  5. Zero-G Thermodynamic Venting System (TVS) Performance Prediction Program

    NASA Technical Reports Server (NTRS)

    Nguyen, Han

    1994-01-01

    This report documents the Zero-g Thermodynamic Venting System (TVS) performance prediction computer program. The zero-g TVS is a device that destratifies and rejects environmentally induced zero-g thermal gradients in the LH2 storage transfer system. A recirculation pump and spray injection manifold recirculates liquid throughout the length of the tank thereby destratifying both the ullage gas and liquid bulk. Heat rejection is accomplished by the opening of the TVS control valve which allows a small flow rate to expand to a low pressure thereby producing a low temperature heat sink which is used to absorb heat from the recirculating liquid flow. The program was written in FORTRAN 77 language on the HP-9000 and IBM PC computers. It can be run on various platforms with a FORTRAN compiler.

  10. Experimental system of free viewpoint television

    NASA Astrophysics Data System (ADS)

    Na Bangchang, Purim; Fujii, Toshiaki; Tanimoto, Masayuki

    2003-05-01

    In this paper, we proposed a new realtime dynamic ray data acquisition and rendering system named the "Free Viewpoint Television" or "FTV". With this system, the user can freely control the viewpoint position of any dynamic real-world scene in realtime. The basic idea of this system is based on the ray-space method in which an arbitrary photo-realistic view can be generated from a collection of real view images. Since the system is aimed for realtime operation, the collection of images is obtained through an array of cameras where the generation of the missing ray information can be obtained by interpolation of data between cameras. The prototype system used here includes 16 CCD cameras forming a camera array. The interpolation is based on the adaptive filtering ray-space data interpolation technique. Between each pair of cameras, up to 15 interpolated views can be generated to ensure that no aliasing occurs. The system fully operates under consumer-class hardware. The results achieved from the system are good in terms of both image quality and rendering speed.

    The various optical measuring methods for deriving information about the size and form of objects are now used in difference branches- mechanical engineering, medicine, art, criminalistics. Measuring by means of the digital television systems is one of these methods. The development of this direction is promoted by occurrence on the market of various types and costs small-sized television cameras and frame grabbers. There are many television measuring systems using the expensive cameras, but accuracy performances of low cost cameras are also interested for the system developers. For this reason inexpensive mountingless camera SK1004CP (format 1/3', cost up to 40$) and frame grabber Aver2000 were used in experiments.

  16. Telecommunications: Additional Federal Efforts Could Help Advance Digital Television Transition

    NASA Astrophysics Data System (ADS)

    2002-11-01

    The transition to broadcast digital television(DTV) will provide new television services and the improved picture quality of 'high definition television'. It will also allow some portions of the radiofrequency spectrum used for broadcasting to be returned for public safety and commercial uses. The Congress set December 2006 as the target date for completing the DTV transition and turning the analog broadcast signals. However, this date can be extended if fewer than 85 percent of households in a market are able to receive the digital signals. GAO (General Accounting Office) was asked to assess issues related to the DTV transition.

    NASA Technical Reports Server (NTRS)

    Kravitz, M.; Freedman, L. A.; Fredd, E. H.; Denef, D. E. (Inventor)

    1985-01-01

    A video level control system is provided which generates a normalized video signal for a camera processing circuit. The video level control system includes a lens iris which provides a controlled light signal to a camera tube. The camera tube converts the light signal provided by the lens iris into electrical signals. A feedback circuit in response to the electrical signals generated by the camera tube, provides feedback signals to the lens iris and the camera tube. This assures that a normalized video signal is provided in a first illumination range. An automatic gain control loop, which is also responsive to the electrical signals generated by the camera tube 4, operates in tandem with the feedback circuit. This assures that the normalized video signal is maintained in a second illumination range.

  2. Boeing Satellite Television Airplane Receiving System (STARS) performance

    NASA Technical Reports Server (NTRS)

    Vertatschitsch, Edward J.; Fitzsimmons, George W.

    1995-01-01

    Boeing Defense and Space Group is developing a Satellite Television Airplane Receiving System (STARS) capable of delivering Direct Broadcast Satellite (DBS) television to an aircraft in-flight. This enables a new service for commercial airplanes that will make use of existing and future DBS systems. The home entertainment satellites, along with STARS, provide a new mobile satellite communication application. This paper will provide a brief background of the antenna issues associated with STARS for commercial airplanes and then describe the innovative Boeing phased-array solution to these problems. The paper then provides a link budget of the STARS using the Hughes DBS as an example, but the system will work with all of the proposed DBS satellites in the 12.2-12.7 GHz band. It concludes with operational performance calculations of the STARS system, supported by measured test data of an operational 16-element subarray. Although this system is being developed for commercial airplanes, it is well suited for a wide variety of mobile military and other commercial communications systems in air, on land and at sea. The applications include sending high quality video for the digital battlefield and large volumes of data on the information superhighway at rates in excess of 350 Mbps.

  5. Orbital docking system centerline color television camera system test

    NASA Technical Reports Server (NTRS)

    Mongan, Philip T.

    1993-01-01

    A series of tests was run to verify that the design of the centerline color television camera (CTVC) system is adequate optically for the STS-71 Space Shuttle Orbiter docking mission with the Mir space station. In each test, a mockup of the Mir consisting of hatch, docking mechanism, and docking target was positioned above the Johnson Space Center's full fuselage trainer, which simulated the Orbiter with a mockup of the external airlock and docking adapter. Test subjects viewed the docking target through the CTVC under 30 different lighting conditions and evaluated target resolution, field of view, light levels, light placement, and methods of target alignment. Test results indicate that the proposed design will provide adequate visibility through the centerline camera for a successful docking, even with a reasonable number of light failures. It is recommended that the flight deck crew have individual switching capability for docking lights to provide maximum shadow management and that centerline lights be retained to deal with light failures and user preferences. Procedures for light management should be developed and target alignment aids should be selected during simulated docking runs.

  6. Environmental performance evaluation of an advanced-design solid-state television camera

    NASA Technical Reports Server (NTRS)

    1979-01-01

    The development of an advanced-design black-and-white solid-state television camera which can survive exposure to space environmental conditions was undertaken. A 380 x 488 element buried-channel CCD is utilized as the image sensor to ensure compatibility with 525-line transmission and display equipment. Specific camera design approaches selected for study and analysis included: (1) component and circuit sensitivity to temperature; (2) circuit board thermal and mechanical design; and (3) CCD temperature control. Preferred approaches were determined and integrated into the final design for two deliverable solid-state TV cameras. One of these cameras was subjected to environmental tests to determine stress limits for exposure to vibration, shock, acceleration, and temperature-vacuum conditions. These tests indicate performance at the design goal limits can be achieved for most of the specified conditions.

  14. PC-based closed-circuit television system

    NASA Astrophysics Data System (ADS)

    Christoffersen, Daniel; Clark, Carl

    The PC-based closed-circuit television (CCTV) system is a low-cost, highly functional alternative to conventional video system equipment. The system provides routing switching, character generation, video presence detection, and solid-state video recording and replay by using four uniquely designed boards that fit into the backplane slots of an IBM PC-XT-compatible personal computer. Each board controls 16 separate channels, and the boards can be daisy-chained together to build larger, more powerful systems. The system can be configured to handle as many as 240 input signals or up to 48 output channels, and uses a redundant video bus loop. The video bus can be tapped into throughout the loop to provide localized routing switching within several buildings, and video termination at multiple locations, such as security operators' stations. This approach reduces cabling costs and allows additional routing switchers to be added easily with little impact on existing equipment. The system is capable of communicating with several control interfaces, and control software is currently in place for communicating via an RS-232 link and the Intel BitBus network. The hardware drivers are Microsoft C modules that can be linked with a user developed control program.

    2004-05-01

    We have been developing a new television system named Free Viewpoint Television (FTV) that can generate free views. We propose a new user interface of FTV using an automultiscopic display (multi-viewing autostereoscopic display) and a head tracking system. We made a head tracking system which used cameras and didn't need to attach any sensors to a person. We succeeded to extend the viewing zone of an automultiscopic display. It brought us to interface with FTV naturally.

  17. Digital item for digital human memory--television commerce application: family tree albuming system

    2004-01-01

    Technical advance in creating, storing digital media in daily life enables computers to capture human life and remember it as people do. A critical point with digitizing human life is how to recall bits of experience that are associated by semantic information. This paper proposes a technique for structuring dynamic digital object based on MPEG-21 Digital Item (DI) in order to recall human"s memory and providing interactive TV service on family tree albuming system as one of its applications. DIs are a dynamically reconfigurable, uniquely identified, described by a descriptor language, logical unit for structuring relationship among multiple media resources. Digital Item Processing (DIP) provides the means to interact with DIs to remind context to user, with active properties where objects have executable properties. Each user can adapt DIs" active properties to tailor the behavior of DIs to match his/her own specific needs. DIs" technologies in Intellectual Property Management and Protection (IPMP) can be used for privacy protection. In the interaction between the social space and technological space, the internal dynamics of family life fits well sharing family albuming service via family television. Family albuming service can act as virtual communities builders for family members. As memory is shared between family members, multiple annotations (including active properties on contextual information) will be made with snowballing value.

    Integral three-dimensional (3D) television based on integral imaging requires huge amounts of information. Previously, we constructed an Integral 3D television using Super Hi-Vision (SHV) technology, with 7680 pixels horizontally and 4320 pixels vertically. We report on improved image quality through the development of video system with an equivalent of 8000 scan lines for use with Integral 3D television. We conducted experiments to evaluate the resolution of 3D images using an experimental setup and were able to show that by using the pixel-offset method we have eliminated aliasing produced by full-resolution SHV video equipment. We confirmed that the application of the pixel-offset method to integral 3D television is effective in increasing the resolution of reconstructed images. PMID:23481805

    Feldman, Sidney; Barton, George G.

    1997-01-01

    A unique, versatile, non-mechanical, non-rotating 360 degrees imaging system has been developed and field-tested successively with conventional black and white, color television, 35-mm, motion picture cameras to prove that intruders, vehicles, radiation can be detected and recognized from any direction using one camera. The system consists of a low-cost, unique first surface reflective conical mirror with special computer programmed aspheric surfaces in operation with conventional narrow field of view (FOV) cameras and objective lenses. The cameras are converted to the 360 degree horizontal FOV and flexibility in conical mirror design provides variable elevation FOV to fit the security application. The wide, efficient spectral reflectance of the conical mirror means that UV, LLLTV, far IR thermal TV cameras can be converted, as well, to 360 degree imaging. The TV real-time 360 degree circular image can be processed electronically and presented on the TV monitor as a typical linear undistorted 360 degree rectangular scene or stacked rectangular scenes and also processed to provide analog to digital real-time motion detection and audible alarm to alert security personnel. For the 360 degree imaging systems or any television systems, the motion detection electronics has been designed to function effectively with image digital memory requirements reduced by magnitudes, thereby, increasing computer speed, but reducing computer costs. The 360 degree TV real-time intruder detection systems can operate in internal and external locations. For external locations, optical filtering and electronic processing has been designed to minimize motion detection false alarms caused by the changing illumination, cloud motion, sun glitter, etc. of the outdoor land or marine environment. The versatile 360 degree TV imaging systems objectives are to replace several narrow FOV cameras for an instantaneous 360 degree sweep, accordingly to reduce number of motion detection accessories, to

    Video data require a very large memory capacity. Optimal ratio quality / volume video encoding method is one of the most actual problem due to the urgent need to transfer large amounts of video over various networks. The technology of digital TV signal compression reduces the amount of data used for video stream representation. Video compression allows effective reduce the stream required for transmission and storage. It is important to take into account the uncertainties caused by compression of the video signal in the case of television measuring systems using. There are a lot digital compression methods. The aim of proposed work is research of video compression influence on the measurement error in television systems. Measurement error of the object parameter is the main characteristic of television measuring systems. Accuracy characterizes the difference between the measured value abd the actual parameter value. Errors caused by the optical system can be selected as a source of error in the television systems measurements. Method of the received video signal processing is also a source of error. Presence of error leads to large distortions in case of compression with constant data stream rate. Presence of errors increases the amount of data required to transmit or record an image frame in case of constant quality. The purpose of the intra-coding is reducing of the spatial redundancy within a frame (or field) of television image. This redundancy caused by the strong correlation between the elements of the image. It is possible to convert an array of image samples into a matrix of coefficients that are not correlated with each other, if one can find corresponding orthogonal transformation. It is possible to apply entropy coding to these uncorrelated coefficients and achieve a reduction in the digital stream. One can select such transformation that most of the matrix coefficients will be almost zero for typical images . Excluding these zero coefficients also

    1993-01-01

    This paper introduces the new concept of digital direct satellite broadcasting (D-DBS), which allows unprecedented flexibility by providing a large number of audio-visual services. The concept elaborated on in this paper assumes an information rate of about 40 Mb/s, which is compatible with practically all present-day transponders. After discussion of the general system concept, the optimization procedure is introduced and results of the transmission system optimization are presented. Channel distortion and uplink/downlink interference effects are taken into account by means of a time domain system computer simulation approach. It is shown, by means of link budget analysis, how a medium power direct-to-home TV satellite can provide multimedia services to users equipped with small (60 cm) dish antennas.

We had previously developed an integral 3-D television that used a high-definition television system. The new system uses -6 times as many elemental images [160 (horizontal) x 118 (vertical) elemental images] arranged at -1.5 times the density to improve further the picture quality of the reconstructed image. Through comparison an image near the lens array can be reconstructed at -1.9 times the spatial frequency, and the viewing angle is -1.5 times as wide. PMID:16572684

    Two digital video data compression systems directly applicable to the Space Shuttle TV Communication System were described: (1) For the uplink, a low rate monochrome data compressor is used. The compression is achieved by using a motion detection technique in the Hadamard domain. To transform the variable source rate into a fixed rate, an adaptive rate buffer is provided. (2) For the downlink, a color data compressor is considered. The compression is achieved first by intra-color transformation of the original signal vector, into a vector which has lower information entropy. Then two-dimensional data compression techniques are applied to the Hadamard transformed components of this last vector. Mathematical models and data reliability analyses were also provided for the above video data compression techniques transmitted over a channel encoded Gaussian channel. It was shown that substantial gains can be achieved by the combination of video source and channel coding.

    1975-01-01

    Remotely controlled systems which use television for visual feedback require that depth cues be available to the operator. A number of techniques have been developed to provide stereoptic video. An analysis of parameters of such systems as related to the depth cues of convergence and retinal disparity was carried out. Parameter requirements were determined for the provision of natural and exaggerated stereoptic cues and expressions were developed for range resolution limits based on the retinal disparity threshold. An empirical study was conducted using a stereoptic video system to determine threshold values

  3. Numerical Investigation on Performance of In-Building Plastic Optical Fiber Transmission Systems and Role of Digital Television Broadcasting

    Matera, Francesco; Tiano, Stefania; Settembre, Marina

    2012-07-01

    This article reports a numerical investigation on the transmission performance of multilevel systems operating in building links encompassing step-index plastic optical fibers. For such an aim, a simplified model for the multimode fiber propagation is introduced. A sub-carrier multiplexing technique is also simulated to demonstrate the distribution of broadcasting television channels by adopting such fibers. The reported results show that a unique building network based on step-index plastic optical fibers is suitable to carry both Ethernet and broadcast TV signals in all rooms.

    An optical pickup comprising an electrooptical device located between two crossed polarizing devices all positioned along a common optical axis is described for switching a TV system between a color mode and a black and white mode. Embodiments in which the electrooptical system is used as a neutral density filter, a selective color filter, or a light shutter as applied to a television camera are described. Where the optical system is used as a selective color filter to produce light beams of alternating color in a field sequential color television system, deactivation of the optical system renders the television a black and white system.

    There are two primary methods of transmitting signal of digital television to the home in China. The first one is HFC mode, which is widely used. The other is IPTV mode, which is emerging. In this paper, the scheme of digital television over Ethernet PON is proposed. There are several differences from this system to IPTV and Video over LAN: the real-time transmission of equal-bandwidth based on statistical multiplexing, channel switching based on multicast and IP CA system, etc.. And these are also the key techniques used in this system. The architecture of DTV over EPON system, the function of every component, the framing process and the multiplexing of Ethernet frame are described. The implementation procedure of the system is shown. The mechanism of channel switching using multicast technique is designed and realized. We also present the method of using static VLAN and IGMP snooping mechanism to implement statistical multiplexing on Ethernet layer, and put forward the concept of IP Conditional Access System and define it. An experimental system of DTV over EPON is set up and the experimental result is significant.

    Shatil, Evelyn; Mikulecká, Jaroslava; Bellotti, Francesco; Bureš, Vladimír

    2014-01-01

    The main study objective was to investigate the effect of interactive television-based cognitive training on cognitive performance of 119 healthy older adults, aged 60-87 years. Participants were randomly allocated to a cognitive training group or to an active control group in a single-blind controlled two-group design. Before and after training interactive television cognitive performance was assessed on well validated tests of fluid, higher-order ability, and system usability was evaluated. The participants in the cognitive training group completed a television-based cognitive training programme, while the participants in the active control group completed a TV-based programme of personally benefiting activities. Significant improvements were observed in well validated working memory and executive function tasks in the cognitive training but not in the control group. None of the groups showed statistically significant improvement in life satisfaction score. Participants' reports of "adequate" to "high" system usability testify to the successful development and implementation of the interactive television-based system and compliant cognitive training contents. The study demonstrates that cognitive training delivered by means of an interactive television system can generate genuine cognitive benefits in users and these are measurable using well-validated cognitive tests. Thus, older adults who cannot use or afford a computer can easily use digital interactive television to benefit from advanced software applications designed to train cognition. PMID:24992187

    To solve the inconvenience of routine transportation of chronically ill and handicapped patients, this paper proposes a platform based on a hybrid fiber coaxial (HFC) network in Taiwan designed to make a home telecare system feasible. The aim of this home telecare system is to combine biomedical data, including three-channel electrocardiogram (ECG) and blood pressure (BP), video, and audio into a National Television Standard Committee (NTSC) channel for communication between the patient and healthcare provider. Digitized biomedical data and output from medical devices can be further modulated to a second audio program (SAP) subchannel which can be used for second-language audio in NTSC television signals. For long-distance transmission, we translate the digital biomedical data into the frequency domain using frequency shift key (FSK) technology and insert this signal into an SAP band. The whole system has been implemented and tested. The results obtained using this system clearly demonstrated that real-time video, audio, and biomedical data transmission are very clear with a carrier-to-noise ratio up to 43 dB. PMID:10761772

  12. New Compact And High Resolution Optical Lens System For Projection Television

    NASA Astrophysics Data System (ADS)

    Yoshioka, Takayuki

    1989-07-01

    We have developed a new optical system for projection television to achieve high luminance and excellent image quality with light weight compact size cabinet. This optical lens system has a hybrid structure employing four plastic and one glass lens. By introducing an aspherical surface on both sides of all plastic lenses, we have achieved an improvement of image quality over the entire screen. The lenses controlled to be thinner in this design method simplifies molding. Plastic lenses are imperfect in that they are subject to focus drift due to changes in ambient temperature. To minimize this effect, glass is employed in the main power lens. Furthermore, the lenses are arranged in such a way to eliminate the drift by optimum use of power distribution. This system has a short focal length and thus employs a single-reflection optical path system, ensuring a compact cabinet size and a reduction of chromatic abberation which cannot be achieved by simply introducing aspherical lenses. The design reduced the focal length from our conventional figure of 156 mm to 86 mm. Despite the large aperture FN0 of 1.0 an approximate increase of 30% in the MTF value has been achieved. The image quality is perfectly maintained over a temperature fluctuations of ± 20°C. Overall weight of the lens assembly has been reduced by 1/5. The system has been in operation in Pioneer 40 and 50 inch T.V. sets since 1987. The system is applicable to and essential for the future HDTV.

    1984-03-01

    Intelsat began offering leased transponder capacity for domestic services in 1974. At the end of 1983, thirty-seven 36 MHz transponders had been leased by 24 countries. At present, seven leased international television channels are operating, with an eighth scheduled for 1984. Programming, program receiving, or both, is being shared by eight countries. Intelsat's satellite reliability record has encouraged many countries to realize the benefits of transponder leasing, which is currently based on the use of the Intelsat V and V A satellites. The domestic services provided by the 24 countries through Intelsat can be grouped into four categories: trunk telephony, thin-route telephony, television distribution intended for rebroadcast, and television distribution intended for community reception. Intelsat's international television service has grown from a total of 7300 hours in 1974 to more than 50,000 hours in 1982, using at least 4 channels each to cover the Atlantic, Pacific, and Indian communities. International leasing of television programs among relatively large earth-stations complements Intelsat's television offerings.

    Singhal, A; Doshi, J K; Rogers, E M; Rahman, S A

    1988-01-01

    Between 1980 and 1987, the number of television sets increased by 10 times in India. Television now reaches an audience of about 800 million, 10% of the population. 3 main reasons account for the rapid diffusion of television in India: the role of communication satellites in expanding access to television signals, the introduction and popularity of soap operas, and the increasing revenues to the national television system (Doordarshan) from commercial advertising. Hum Log, the 1st soap opera on the national network, was patterned after pro-development soap operas in Mexico and addresses social issues such as family communication, women's status, small family size, national integration, dowry, and alcoholism. The main lesson from the Hum Log experience was that indigenous soap operas can attract large audiences and substantial profits. A 1987 household survey indicated that television ownership is more common in urban areas (88% of households) than rural areas (52%) and among households with incomes above RS 1500 (75% of television owners). The commercialization of Indian television has precipitated a policy debate about television's role. Supporters of further expansion of television services cite popular will, the potential to use this medium for educational development, high advertising incomes, the ability of satellite television to penetrate rural areas, and high government expenditures for television broadcasting. On the other hand, detractors of the commercialization policy argue that television promotes consumerism, widens the gap between the urban elite and the rural poor, disregards regional sociocultural norms, and diverts funding from development programs in areas such as health and education.

    Digital TV is now being enhanced with interactivity based on such standards as Multimedia Home Platform (MHP) and Digital TV Application Software Environment (DASE). However, recording interactive DTV programme is not that straightforward as it seems. The user will expect the interactivity to still be accessible when a recorded programme is played back from storage. Due to the complexity of the iTV broadcasting, there are many problems for recording interactive TV programme. In this paper we analyze the MHP transport stream structure, describe the recording solution and storage format. Implementation system examples both for recording and playing back are depicted as well.

    2016-09-01

    A substantial number of previous studies have reported significant associations between television viewing habits and a host of detrimental outcomes including increased contact with the criminal justice system. However, it remains unclear whether the results flowing from this literature are generalizable to other samples and whether previously observed associations are confounded due to uncontrolled genetic influences. The current study addresses these limitations using the National Longitudinal Study of Adolescent to Adult Health (Add Health). The results of the preliminary models, which do not include controls for genetic influences, produced a pattern of results similar to those previously reported in the extant literature. The results of the genetically informed models revealed that the associations between television viewing and antisocial outcomes are not causal, but rather are driven by uncontrolled genetic influences. Further replication is required, but these findings suggest that results drawn from the extant literature may not be trustworthy. PMID:25818861

    Gee, S. W.; Carr, P. C.; Winter, W. R.; Manke, J. A.

    1978-01-01

    A flight program was conducted to develop a landing technique with which a pilot could consistently and safely land a remotely piloted research vehicle (RPRV) without outside visual reference except through television. Otherwise, instrumentation was standard. Such factors as the selection of video parameters, the pilot's understanding of the television presentation, the pilot's ground cockpit environment, and the operational procedures for landing were considered. About 30 landings were necessary for a pilot to become sufficiently familiar and competent with the test aircraft to make powered approaches and landings with outside visual references only through television. When steep approaches and landings were made by remote control, the pilot's workload was extremely high. The test aircraft was used as a simulator for the F-15 RPRV, and as such was considered to be essential to the success of landing the F-15 RPRV.

    1979-01-01

    The results are presented of a continuing research and development program the objective of which is to develop a reduced bandwidth television system and a technique for television transmission of holograms. The result of the former is a variable frame rate television system, the operation of which was demonstrated for both black-and-white and color signals. This system employs a novel combination of the inexpensive mass storage capacity of a magnetic disc with the reliability of a digital system for time expansion and compression. Also reported are the results of a theoretical analysis and preliminary feasibility experiment of an innovative system for television transmission of holograms using relatively conventional TV equipment along with a phase modulated reference wave for production of the original interference pattern.

  20. Optical simulations for Ambilight TV systems

    NASA Astrophysics Data System (ADS)

    Bruyneel, Filip; Lanoye, Lieve

    2012-06-01

    Ambilight is a unique Philips feature, where RGB LEDs are used to create a dynamic light halo around the television. This extends the screen and hence increases the viewing experience, as it draws the viewer more into the action on the screen. The feature receives very positive consumer feedback. However, implementing Ambilight in the increasingly stringent design boundary conditions of a slim and thin TV set is a challenging task. Optical simulations play a vital role in each step of the Ambilight development. Ranging from prototype to final product, we use simulations, next to prototyping, to aid the choice of LEDs, optical materials and optical systems during different phases of the design process. Each step the impact of the optical system on the mechanical design and TV set dimensions needs to be taken into account. Moreover, optical simulations are essential to guarantee the required optical performance given a big spread in LED performance, mechanical tolerances and material properties. Next to performance, optical efficiency is also an important parameter to evaluate an optical design, as it establishes the required number of LEDs and the total LED power. As such optical efficiency defines the thermal power which needs to be dissipated by the LED system. The innovation roadmap does not stop here. For future systems we see a miniaturization trend, where smaller LED packages and smaller dies are used. This evolution makes the impact of mechanical tolerances on the optical design more severe. Consequentially, this approach poses a whole new challenge to the way we use optical simulations in our design process.

  13. Television and contraception.

    PubMed

    Klein, L

    1986-01-01

    This article consists of excerpts from a speach made on October 19th at the 1986 annual meeting of the Association of Planned Parenthood Professionals by Dr. Luella Klein, President of the American College of Obstetricians and Gynecologists (ACOG) between 1984-85. The speaker described the reaction of US television network to the ACOG's request that the networks air a public service announcement encouraging responsible sexual behavior among the nation's young people. In 1984 the ACOG initiated a public information program aimed at reducing the high number of unwanted births among young people. The ACOG with the help of an advertising agency developed a 27-second public service announcement stressing responsible parenthood and informing young people that they could write or call for further information. A booklet, entitled "Facts," was prepared for distribution to those who inquired. It advised young people to consider postponing sexual intercourse but to use the most effective methods of contraception if they decided to be sexually active. Oral contraceptives for females and condoms for males were recommended as the most effective methods. When the 3 major television networks, i.e., the American Broadcasting Company (ABC), the National Broadcasting Company (NBC), and the Columbia Broadcasting System (CBS), were requested to carry the announcement, all 3 networks claimed the announcement was too controversial to air. These same networks do not hesitate to show blatant, irresponsible sexual behavior repeatedly during their entertainment programming, and commercials with sexual innuendos are routinely accepted for airing by the networks. In July, 1986, the ACOG called a news conference in New York City to inform the news media about the rejection of the announcement by the networks. The conference stimulated considerable interest, and the story was carried by many newspapers and by radio and television news programs. Many of the news accounts of the story contained

    Sato, Eiichi; Isobe, Hiroshi; Takahashi, Kei; Tamakawa, Yoshiharu; Yanagisawa, Toru

    1991-04-01

    The fundamental studies for the repetitive flash x-ray generator operated at lowdose rates for a medical x-ray television system are described. This x-ray generator consisted of the following components: a high-voltage power supply, an energy storage condenser of lOOnF, a coaxial cable condenser with a capacity of l000pF, a repetitive impulse switching system, a turbo molecular pump, and an x-ray tube having a cold cathode. The condenser was charged from 40 to 70kV by a power supply, and the electric charges stored in the condenser were discharged repetitively by using a trigger electrode operated by an impulse switching system. The x-ray tube was of the triode-type which was connected to the turbo molecular pump and had a large discharge impedance in order to prevent the damped oscillations of the tube current and voltage. The maximum tube voltage was equivalent to the initial charged voltage, and the peak current was less than 70A. The durations were about 2ps, and the x-ray intensities were less than 1. OpC/kg at 0. 5m per pulse. The repetition frequency was less than 50Hz, and the effective focal spot size was equivalent to the anode diameter of 3. 0mm. For the x-ray television system used in conjunction with this repetitive pulsed x-ray generator, since the electromagnetic noise primarily caused by the high tube current was decreased, noise-free stroboscopic radiography performed by the television system could be realized.

    Chang, Ching-Hung; Liu, Wei-Chen; Peng, Peng-Chun; Lu, Hai-Han; Wu, Po-Yi; Wang, Jyun-Bo

    2011-05-01

    A hybrid community antenna television (CATV) and orthogonal-frequency-division-multiplexing (OFDM) transport system is proposed and experimentally demonstrated to transmit multiple CATV channels and bi-directional radio frequency signals on a single optical carrier. By polarization remodulating an optical CATV signal with downstream OFDM signals and then amplitude remodulating upstream OFDM signals with the hybrid CATV/OFDM signals, this architecture can efficiently utilize only one optical carrier to support optical analog/digital CATV transmission and bi-directional wireless broadband services for each client. Good experimental results prove that this architecture provides a proper wavelength utilization scheme for future multiwavelength optical transport systems. PMID:21540979

    Blackburn, Steven; Brownsell, Simon; Hawley, Mark S

    2011-01-01

    We conducted a systematic review of the applications and technical features of digital interactive television (DITV) in the health and social care fields. The Web of Knowledge and IEEE Xplore databases were searched for articles published between January 2000 and March 2010 which related to DITV systems facilitating the communication of information to/from an individual's home with either a health or social care application. Out of 1679 articles retrieved, 42 met the inclusion criteria and were selected for review. An additional 20 articles were obtained from online grey literature sources. Twenty-five DITV systems operating in health and social care were identified, including seven commercial systems. The most common applications were related to health care, such as vital signs monitoring (68% of systems) and health information or advice (56% of systems). The most common technical features of DITV systems were two-way communication (88%), medical peripherals (68%), on-screen messaging (48%) and video communication (36%). Digital interactive television has the potential to deliver health and social care to people in their own homes. However, the requirement for a high-bandwidth communications infrastructure, the usability of the systems, their level of personalisation and the lack of evidence regarding clinical and cost-effectiveness will all need to be addressed if this approach is to flourish.

  11. ObesiTV: how television is influencing the obesity epidemic.

    PubMed

    Boulos, Rebecca; Vikre, Emily Kuross; Oppenheimer, Sophie; Chang, Hannah; Kanarek, Robin B

    2012-08-20

    Obesity is a major public health concern in the United States. Over the last several decades, the prevalence of obesity among both adults and children has grown at an alarming rate and is now reaching epidemic proportions. The increase in obesity has been associated with rises in a host of other chronic conditions including cardiovascular disease, type 2 diabetes, and some cancers. While the causes of obesity are multifaceted, there is growing evidence that television viewing is a major contributor. Results of numerous studies indicate a direct association between time spent watching television and body weight. Possible explanations for this relationship include: 1) watching television acts as a sedentary replacement for physical activity; 2) food advertisements for nutrient-poor, high-calorie foods stimulate food intake; and 3) television viewing is associated with "mindless" eating. In addition to decreasing physical activity and increasing the consumption of highly palatable foods, television viewing can also promote weight gain in indirect ways, such as through the use of targeted product placements in television shows; by influencing social perceptions of body image; and airing programs that portray cooking, eating and losing weight as entertainment. This paper will provide an interdisciplinary review of the direct and indirect ways in which television influences the obesity epidemic, and conclude with ways in which the negative impact of television on obesity could be reduced.

  12. Television Transmission Technology

    NASA Technical Reports Server (NTRS)

    1996-01-01

    The VKP-7990 Multistage Depressed Collector (MDC) Klystron is a result of cooperative development by Varian Associates, Inc., the National Association of Broadcasters, Lewis Research Center, the Public Broadcasting System and TV transmitter manufacturers. The effort was initiated to make power amplifying devices with efficiencies comparable to VHF available to UHF operators. The klystron is a vacuum tube used to generate and amplify ultrahigh frequencies but at low efficiencies because most of the energy is dissipated as waste heat. Lewis had earlier developed the MDC to enhance the efficiency of communications satellite transmissions. Varian Microwave Power Tube Products, which has since become Communications and Power Industries, and Lewis combined the MDC and the klystron, resulting in a product which increases efficiency by recovering some of the residual energy that normally would be lost as heat. The MDC klystron cuts the electric power consumption of UHF-TV transmitters in half; there are 90 units in operation in 36 UHF-TV stations.

  17. Multitasking With Television Among Adolescents

    PubMed Central

    Christensen, Claire G.; Bickham, David; Ross, Craig S.; Rich, Michael

    2015-01-01

    Using Ecological Momentary Assessment, we explored predictors of adolescents’ television (TV) multitasking behaviors. We investigated whether demographic characteristics (age, gender, race/ethnicity, and maternal education) predict adolescents’ likelihood of multitasking with TV. We also explored whether characteristics of the TV-multitasking moment (affect, TV genre, attention to people, and media multitasking) predict adolescents’ likelihood of paying primary versus secondary attention to TV. Demographic characteristics do not predict TV multitasking. In TV-multitasking moments, primary attention to TV was more likely if adolescents experienced negative affect, watched a drama, or attended to people; it was less likely if they used computers or video games.

    This paper describes experiments designed to evaluate the impact of HDTV on the performance of typical remote tasks. The experiments described in this paper compared the performance of four operators using HDTV with their performance while using other television systems. The experiments included four television systems: (1) high-definition color television, (2) high-definition monochromatic television, (3) standard-resolution monochromatic television, and (4) standard-resolution stereoscopic monochromatic television. The stereo system accomplished stereoscopy by displaying two cross-polarized images, one reflected by a half-silvered mirror and one seen through the mirror. Observers wore a pair of glasses with cross-polarized lenses so that the left eye received only the view from the left camera and the right eye received only the view from the right camera.

  1. Television and children's executive function.

    PubMed

    Lillard, Angeline S; Li, Hui; Boguszewski, Katie

    2015-01-01

    Children spend a lot of time watching television on its many platforms: directly, online, and via videos and DVDs. Many researchers are concerned that some types of television content appear to negatively influence children's executive function. Because (1) executive function predicts key developmental outcomes, (2) executive function appears to be influenced by some television content, and (3) American children watch large quantities of television (including the content of concern), the issues discussed here comprise a crucial public health issue. Further research is needed to reveal exactly what television content is implicated, what underlies television's effect on executive function, how long the effect lasts, and who is affected.

    PubMed Central

    Clarke, Ken; Kwong, Mabel; Alzougool, Basil; Hines, Carolyn; Tidhar, Gil; Frukhtman, Feodor

    2014-01-01

    Background The use of Internet protocol television (IPTV) as a channel for consumer health information is a relatively under-explored area of medical Internet research. IPTV may afford new opportunities for health care service providers to provide health information and for consumers, patients, and caretakers to access health information. The technologies of Web 2.0 add a new and even less explored dimension to IPTV’s potential. Objective Our research explored an application of Web 2.0 integrated with IPTV for personalized home-based health information in diabetes education, particularly for people with diabetes who are not strong computer and Internet users, and thus may miss out on Web-based resources. We wanted to establish whether this system could enable diabetes educators to deliver personalized health information directly to people with diabetes in their homes; and whether this system could encourage people with diabetes who make little use of Web-based health information to build their health literacy via the interface of a home television screen and remote control. Methods This project was undertaken as design-based research in two stages. Stage 1 comprised a feasibility study into the technical work required to integrate an existing Web 2.0 platform with an existing IPTV system, populated with content and implemented for user trials in a laboratory setting. Stage 2 comprised an evaluation of the system by consumers and providers of diabetes information. Results The project succeeded in developing a Web 2.0 IPTV system for people with diabetes and low literacies and their diabetes educators. The performance of the system in the laboratory setting gave them the confidence to engage seriously in thinking about the actual and potential features and benefits of a more widely-implemented system. In their feedback they pointed out a range of critical usability and usefulness issues related to Web 2.0 affordances and learning fundamentals. They also described

    Underhill, A. B.

    1984-01-01

    Low-resolution SWP spectra and high-resolution LWR spectra of the SRc variable star TV Gem have been studied. The available ultraviolet spectrophotometry and UBV photometry of the system can be interpreted in terms of the blended light from a B3.5 IV star and an M1 Iab star. The separation of the two stars is less than about 3 arc sec. Since the magnitude difference is a minimum in the B filter, being about 1.6 mag there, direct observation of TV Gem in a passband at 4400 A under conditions of good seeing might reveal the blue companion. No evidence was found for absorption lines of Mg II formed in the part of the wind of the M star which is projected against the disk of the B star.

    Brown, J D; Childers, K W; Waszak, C S

    1990-01-01

    Existing studies of the sexual content of television programming and advertising and the effects of this content on adolescent viewers are reviewed. Content studies show that the frequency of sexual references have increased in the past decade and are increasingly explicit. Studies of the effects of this content, while scarce, suggest that adolescents who rely heavily on television for information about sexuality will have high standards of female beauty and will believe that premarital and extramarital intercourse with multiple partners is acceptable. They are unlikely to learn about the need for contraceptives as a form of protection against pregnancy or disease. Suggestions for future research and trends in television programming policies are explored. PMID:2307597

    A system which simulates observation of the earth surface by aerial or orbiting television devices has been developed. By projecting color slides of photographs taken by aircraft and orbiting sensors upon a rear screen system, and altering scale of projected image, screen position, or TV camera position, it is possible to simulate alternatives of altitude, or optical systems. By altering scan line patterns in COHU 3200 series camera from 525 to 945 scan lines, it is possible to study implications of scan line resolution upon the detection and analysis of geographic patterns observed by orbiting TV systems.

  16. A Target Advertisement System Based on TV Viewer's Profile Reasoning

    NASA Astrophysics Data System (ADS)

    Lim, Jeongyeon; Kim, Munjo; Lee, Bumshik; Kim, Munchurl; Lee, Heekyung; Lee, Han-Kyu

    With the rapidly growing Internet, the Internet broadcasting and web casting service have been one of the well-known services. Specially, it is expected that the IPTV service will be one of the principal services in the broadband network [2]. However, the current broadcasting environment is served for the general public and requires the passive attitude to consume the TV programs. For the advanced broadcasting environments, various research of the personalized broadcasting is needed. For example, the current unidirectional advertisement provides to the TV viewers the advertisement contents, depending on the popularity of TV programs, the viewing rates, the age groups of TV viewers, and the time bands of the TV programs being broadcast. It is not an efficient way to provide the useful information to the TV viewers from customization perspective. If a TV viewer does not need particular advertisement contents, then information may be wasteful to the TV viewer. Therefore, it is expected that the target advertisement service will be one of the important services in the personalized broadcasting environments. The current research in the area of the target advertisement classifies the TV viewers into clustered groups who have similar preference. The digital TV collaborative filtering estimates the user's favourite advertisement contents by using the usage history [1, 4, 5]. In these studies, the TV viewers are required to provide their profile information such as the gender, job, and ages to the service providers via a PC or Set-Top Box (STB) which is connected to digital TV. Based on explicit information, the advertisement contents are provided to the TV viewers in a customized way with tailored advertisement contents. However, the TV viewers may dislike exposing to the service providers their private information because of the misuse of it. In this case, it is difficult to provide appropriate target advertisement service.

    2009-02-01

    A European consortium of six partners has been developing core technological components of a mobile 3D television system over DVB-H channel. In this overview paper, we present our current results on developing optimal methods for stereo-video content creation, coding and transmission and emphasize their significance for the power-constrained mobile platform, equipped with auto-stereoscopic display. We address the user requirements by applying modern usercentered approaches taking into account different user groups and usage contexts in contrast to the laboratory assessment methods which, though standardized, offer limited applicability to real applications. To this end, we have been aiming at developing a methodological framework for the whole system development process. One of our goals has been to further develop the user-centered approach towards experienced quality of critical system components. In this paper, we classify different research methods and technological solutions analyzing their pros and constraints. Based on this analysis we present the user-centered methodological framework being used throughout the whole development process of the system and aimed at achieving the best performance and quality appealing to the end user.

    2015-04-01

    This review addresses various approaches to television projection imaging on large screens using lasers. Results are presented of theoretical and experimental studies of an acousto-optic projection system operating on the principle of projecting an image of an entire amplitude-modulated television line in a single laser pulse. We consider characteristic features of image formation in such a system and the requirements for its individual components. Particular attention is paid to nonlinear distortions of the image signal, which show up most severely at low modulation signal frequencies. We discuss the feasibility of improving the process efficiency and image quality using acousto-optic modulators and pulsed lasers. Real-time projectors with pulsed line imaging can be used for controlling high-intensity laser radiation.

    1990-01-01

    A low light-level TV camera is used to obtain an unusual image of luminous electrical discharge over a thunderstorm 250 km from the observation site. The image is presented and the discharge in the image is described. It is suggested that the image is probably due to two localized electric charge concentrations at the cloud tops. The hazard of these discharges for aircraft and rocket launches is examined. Consideration is given to the possibility that these discharges may account for unexplained photometric observations of distant lightning events that show a low rise rate of the luminous pulse and no electromagnetic sferic pulse like that in cloud-to-earth lightning strokes. The photometric events of this type that occurred on September 22-23, 1989 during hurricane Hugo are noted.

  1. DBS television systems under development in the United States of America

    NASA Astrophysics Data System (ADS)

    Clark, J. F.

    1985-01-01

    DBS system technology tradeoffs which were being considered as of October 1984 are reviewed. The economic goal is to provide acceptable image and programming quality at costs lower than those of CATV systems. Although receiver dish antenna costs are incurred by the DBS user, the satellite link avoids the capital intensive cable infrastructure. The DBS antennas may cause legal difficulties as DBS subscribers receive CATV regional unscrambled feeder signals. DBS service at 11 GHz has already begun in the NE U.S. with the Anik C2 satellite, which provides a 10 dB clear sky carrier/noise (C/N) ratio signal. Transponders on a Comsat DBS system (in advanced development) will employ vertically polarized signals to attain C/N ratios over 17 dB in concert with 75 cm home terminal antennas. The FCC has ruled that all DBS equipment shall have sufficient commonality at the receiving end so that a customer will need only to replace a baseband processor unit to change sources.

  2. Enabling active and healthy ageing decision support systems with the smart collection of TV usage patterns

    Smart monitoring of seniors behavioural patterns and more specifically activities of daily living have attracted immense research interest in recent years. Development of smart decision support systems to support the promotion of health smart homes has also emerged taking advantage of the plethora of smart, inexpensive and unobtrusive monitoring sensors, devices and software tools. To this end, a smart monitoring system has been used in order to extract meaningful information about television (TV) usage patterns and subsequently associate them with clinical findings of experts. The smart TV operating state remote monitoring system was installed in four elderly women homes and gathered data for more than 11 months. Results suggest that TV daily usage (time the TV is turned on) can predict mental health change. Conclusively, the authors suggest that collection of smart device usage patterns could strengthen the inference capabilities of existing health DSSs applied in uncontrolled settings such as real senior homes.

  3. An intelligent subtitle detection model for locating television commercials.

    PubMed

    Huang, Yo-Ping; Hsu, Liang-Wei; Sandnes, Frode-Eika

    2007-04-01

    A strategy for locating television (TV) commercials in TV programs is proposed. Based on the observation that most TV commercials do not have subtitles, the first stage exploits six subtitle constraints and an adaptive neurofuzzy inference system model to determine whether a frame contains a subtitle or not. The second stage involves locating the mark-in/mark-out points using a genetic algorithm. An interactive user interface allows users to efficiently identify and fine-tune the exact boundaries separating the commercials from the program content. Furthermore, erroneous boundaries are manually corrected. Experimental results show that the precision rate and recall rates exceed 90%. PMID:17416175

    1992-01-01

    The two component dustball model was used in numerical lag computation. Detached grain lag is typically less than 2 km, with expected wakes of a few hundred meters. True wake in television meteors is masked by apparent wake due to the combined effects of image persistence and blooming. To partially circumvent this problem, we modified a dual MCP intensified CID video system by addition of a rotating shutter to reduce the effective exposure time to about 2.0 ms. Preliminary observations showed that only 2 of 27 analyzed meteors displayed statistically significant wake.

  15. The MiSPOT System: Personalized Publicity and Marketing over Interactive Digital TV

    NASA Astrophysics Data System (ADS)

    López-Nores, Martín; Pazos-Arias, José Juan; Blanco-Fernández, Yolanda; García-Duque, Jorge; Tubío-Pardavila, Ricardo; Rey-López, Marta

    The development of Interactive Digital TV bears a great potential for electronic commerce, which remains heavily underexploited to date. The early initiatives to harness these technologies rely on the advertising techniques traditionally employed by the television industry, which have proven deficiencies related to viewers' comfort, locality and targeting. Furthermore, out of dedicated channels, there are very few attempts to provide interactive commercial functionalities through the TV, for example to sell products or to hire services. This chapter presents an overview of a system called MiSPOT that introduces solutions to these problems in two levels: (i) to advertise items that match the preferences and needs of the viewers, without interfering with their enjoyment of the TV programs; and (ii) to assemble specialized interactive applications that provide them with tailor-made commercial functionalities. These solutions are grounded on techniques from the Semantic Web, and are valid for both domestic TV receivers and mobile ones.

  16. Evaluation of high-definition television for remote task performance

    SciTech Connect

    Draper, J.V.; Fujita, Y.; Herndon, J.N.

    1987-04-01

    High-definition television (HDTV) transmits a video image with more than twice the number (1125 for HDTV to 525 for standard-resolution TV) of horizontal scan lines that standard-resolution TV provides. The improvement in picture quality (compared to standard-resolution TV) that the extra scan lines provide is impressive. Objects in the HDTV picture have more sharply defined edges, better contrast, and more accurate reproduction of shading and color patterns than do those in the standard-resolution TV picture. Because the TV viewing system is a key component for teleoperator performance, an improvement in TV picture quality could mean an improvement in the speed and accuracy with which teleoperators perform tasks. This report describes three experiments designed to evaluate the impact of HDTV on the performance of typical remote tasks. The performance of HDTV was compared to that of standard-resolution, monochromatic TV and standard-resolution, stereoscopic, monochromatic TV in the context of judgment of depth in a televised scene, visual inspection of an object, and performance of a typical remote handling task. The results of the three experiments show that in some areas HDTV can lead to improvement in teleoperator performance. Observers inspecting a small object for a flaw were more accurate with HDTV than with either of the standard-resolution systems. High resolution is critical for detection of small-scale flaws of the type in the experiment (a scratch on a glass bottle). These experiments provided an evaluation of HDTV television for use in tasks that must be routinely performed to remotely maintain a nuclear fuel reprocessing facility. 5 refs., 7 figs., 9 tabs.

    Instead of colorimetirc color reproduction, preferred color correction is applied for digital TVs to improve subjective image quality. First step of the preferred color correction is to survey the preferred color coordinates of memory colors. This can be achieved by the off-line human visual tests. Next step is to extract pixels of memory colors representing skin, grass and sky. For the detected pixels, colors are shifted towards the desired coordinates identified in advance. This correction process may result in undesirable contours on the boundaries between the corrected and un-corrected areas. For digital TV applications, the process of extraction and correction should be applied in every frame of the moving images. This paper presents a preferred color correction method in LCH color space. Values of chroma and hue are corrected independently. Undesirable contours on the boundaries of correction are minimized. The proposed method change the coordinates of memory color pixels towards the target color coordinates. Amount of correction is determined based on the averaged coordinate of the extracted pixels. The proposed method maintains the relative color difference within memory color areas. Performance of the proposed method is evaluated using the paired comparison. Results of experiments indicate that the proposed method can reproduce perceptually pleasing images to viewers.

    We examined the nutritional content of and characters' attitudes toward foods depicted in Public Broadcasting System (PBS) television programs aimed at children under age 5. Two-hundred and forty-five episodes from 10 programs were rated, totaling 136 h. There was almost twice the total airtime for depictions of unhealthy (321.03 min) versus healthy (184.72 min) foods, and significantly higher ratings for excessive consumption and valuing (characters' expressions of endorsement) of unhealthy versus healthy foods. Unhealthy foods were shown being valued significantly more than they were shown resulting in negative consequences. Our findings suggest concern for how foods are presented on children's television programs. PMID:18691621

    Obtaining sufficient labelled training data is a persistent difficulty for speech recognition research. Although well transcribed data is expensive to produce, there is a constant stream of challenging speech data and poor transcription broadcast as closed-captioned television. We describe a reliable unsupervised method for identifying accurately transcribed sections of these broadcasts, and show how these segments can be used to train a recognition system. Starting from acoustic models trained on the Wall Street Journal database, a single iteration of our training method reduced the word error rate on an independent broadcast television news test set from 62.2% to 59.5%.

    2012-03-01

    A holographic television system, featuring realtime incoherent 3D capture and live holographic display is used for experiments in depth perception. Holographic television has the potential to provide more complete visual representations, including latency-free motion parallax and more natural affordances for accommodation. Although this technology has potential to improve realism in many display applications, we investigate benefits in uses where direct vision of a workspace is not possible. Applications of this nature include work with hazardous materials, teleoperation over distance, and laparoscopic surgery. In this study, subjects perform manual 3D object manipulation tasks where they can only see the workspace through holographic closed-circuit television. This study is designed to compare performance at manual tasks using holographic television compared to performance with displays that mimic 2D, and stereoscopic television.

  17. Tapping the television cable.

    PubMed

    Clarke, M; Findlay, A; Canac, J F; Vergez, A

    1996-01-01

    Immediate access to patient data is essential to support good clinical decision making and support. However, away from the surgery, the doctor is currently unable to have any access to the clinical database. Solutions exist to support remote access, such as modems or radio data networks, but these are slow, with typical speeds in the 2-10 kbaud region. We propose a novel solution, to use the TV cable already installed in many homes. Using this technology, a suitably equipped computer (RF modern) is capable of connecting at speeds in excess of 500 kbaud and will run applications in exactly the same way as if connected to a surgery network: the cable TV becomes a LAN, but on a metropolitan scale. Brunel University, in collaboration with the Cable Corporation, has been piloting such a network. Issues include not only levels of service, but also security on the network and access, since the data are being effectively received in every home. However, close scrutiny of channel use can create closed networks reserved for specific users. The technology involves use of an RF modem to transmit data on a reverse channel (based at 16 MHz) on each subnet to a router at the head end of the cable network. This frequency translates the packet and retransmits it to all the subnets on a forward channel (based at 178 MHz). Each channel occupies the bandwidth normally allocated to one TV channel. Access is based on a modified CSMA/CD protocol, so treating the cable network as single multiple access network. The modem comes as a standard card installed in a PC and appears much as an ethernet card, but at reduced speed. With an NDIS driver it is quite able to support almost any network software, and has successfully demonstrated Novell and TCP/IP. We describe the HomeWorker network and the results from a pilot study being undertaken to determine the performance of the system and its impact on working practice. PMID:9375105

  20. Reuse of secondhand TVs exported from Japan to the Philippines

    Yoshida, Aya; Terazono, Atsushi

    2010-06-15

    The trade of secondhand electrical and electronic equipment (EEE) from developed to developing countries has become a growing environmental issue owing to concerns about improper recycling of these goods in developing countries. We followed a 12-m cargo container of cathode-ray-tube color TVs exported from Japan to the Philippines in February 2008. We surveyed the number of TVs damaged in transport, as well as the number of malfunctioning TVs from this shipment. In addition, we present the results of interviews with 113 Filipino consumers who intended to buy secondhand EEE at nine secondhand shops in Metro Manila. Approximately 3% of the imported TVs were damaged upon arrival. The importer sold some of the units directly to local dealers, and kept the rest to repair, refurbish and resell. Approximately 40% of the imported TVs malfunctioned and needed repair in addition to basic reconditioning. Most interviewees indicated that they prefer to buy secondhand EEE because the prices are lower than those of brand-new products. Consumers indicated that they planned on using the product for an average of about 5 years, but the actual period of use may be lower. Most end-of-life EEE in the Philippines is dismantled and recycled by unregulated companies and untrained individuals in markets or near landfill sites, and it is clear that a proper collection system and treatment methods are needed for e-waste. In addition to the material flow of secondhand TVs, we also discuss several economic aspects and appropriate control measures of the international reuse of secondhand TVs.

  18. Face Recognition System for Set-Top Box-Based Intelligent TV

    PubMed Central

    Lee, Won Oh; Kim, Yeong Gon; Hong, Hyung Gil; Park, Kang Ryoung

    2014-01-01

    Despite the prevalence of smart TVs, many consumers continue to use conventional TVs with supplementary set-top boxes (STBs) because of the high cost of smart TVs. However, because the processing power of a STB is quite low, the smart TV functionalities that can be implemented in a STB are very limited. Because of this, negligible research has been conducted regarding face recognition for conventional TVs with supplementary STBs, even though many such studies have been conducted with smart TVs. In terms of camera sensors, previous face recognition systems have used high-resolution cameras, cameras with high magnification zoom lenses, or camera systems with panning and tilting devices that can be used for face recognition from various positions. However, these cameras and devices cannot be used in intelligent TV environments because of limitations related to size and cost, and only small, low cost web-cameras can be used. The resulting face recognition performance is degraded because of the limited resolution and quality levels of the images. Therefore, we propose a new face recognition system for intelligent TVs in order to overcome the limitations associated with low resource set-top box and low cost web-cameras. We implement the face recognition system using a software algorithm that does not require special devices or cameras. Our research has the following four novelties: first, the candidate regions in a viewer's face are detected in an image captured by a camera connected to the STB via low processing background subtraction and face color filtering; second, the detected candidate regions of face are transmitted to a server that has high processing power in order to detect face regions accurately; third, in-plane rotations of the face regions are compensated based on similarities between the left and right half sub-regions of the face regions; fourth, various poses of the viewer's face region are identified using five templates obtained during the initial user

  1. 3-D Television Without Glasses: On Standard Bandwidth

    NASA Astrophysics Data System (ADS)

    Collender, Robert B.

    1983-10-01

    This system for stereoscopic television uses relative camera to scene translating motion and does not require optical aids at the observer's eyes, presents a horizontal parallax (hologram like) 3-D full motion scene to a wide audience, has no dead zones or pseudo 3-D zones over the entire horizontal viewing field and operates on standard telecast signals requiring no changes to the television studio equipment or the home television antenna. The only change required at the receiving end is a special television projector. The system is compatible with pre-recorded standard color television signals. The cathode ray tube is eliminated by substituting an array of solid state charge couple device liquid crystal light valves which have the property to receive television fields in parallel from memory and which are arrayed in an arc for scanning purposes. The array contains a scrolled sequence of successive television frames which serve as the basis for 3-D horizontal viewing parallax. These light valves reflect polarized light with the degree of polarization made a function of the scene brightness. The array is optically scanned and the sequence rapidly projected onto a cylindrical concaved semi-specular screen that returns all of the light to a rapidly translating vertical "aerial" exit slit of light through which the audience views the reconstructed 3-D scene.

  11. Broadcasting presence: immersive television

    NASA Astrophysics Data System (ADS)

    Harrison, David; Lodge, Nicholas

    2000-06-01

    Being present at a live event is undeniably the most exciting way to experience any entertainment. This is true whether we are talking about a musical concert, a theatrical performance, a cricket match, or even a firework display. The ability to direct your gaze where you wish, to hear sounds from all around you, to experience the immediacy and expectation of an unscripted happening, to feel the buzz of the crowd and to smell the grass or smoke, are all sensory cues which contribute to the powerful experience of being there. This paper examines the ways in which entertainment media have attempted to recreate experiences which encourage the viewer to suspend disbelief and become part of a remote or recorded event. We introduce the concept of immersive television and look at some of the research, spanning many disciplines of science and art, which the ITC is conducting to explore the potential of this new medium.

    According to the technical features and requirements of the television imaging system for tracking and measuring, we designed a TV system with focal length of 2800mm, F/11.7 and 2ω(FOV) of 14.2'. The system is compact and easy to fabricate and align, with good image quality. Meanwhile, we performed stray light analysis with ASAP optical software, described stray light suppression techniques used in the TV for tracking and measuring, proposed a method to determine optical properties of the system components and parameters of the scattering model reasonably. We calculated the PST curve of the system for incident angle from -45° to 45°. The results show that when the off-axis angle is larger than the critical incident angle of the sun, PST value is less than 10-8.

  4. Remote health monitoring for elderly through interactive television

    PubMed Central

    2012-01-01

    Background Providing remote health monitoring to specific groups of patients represents an issue of great relevance for the national health systems, because of the costs related to moving health operators, the time spent to reach remote sites, and the high number of people needing health assistance. At the same time, some assistance activities, like those related to chronical diseases, may be satisfied through a remote interaction with the patient, without a direct medical examination. Methods Moving from this considerations, our paper proposes a system architecture for the provisioning of remote health assistance to older adults, based on a blind management of a network of wireless medical devices, and an interactive TV Set Top Box for accessing health related data. The selection of TV as the interface between the user and the system is specifically targeted to older adults. Due to the private nature of the information exchanged, a certified procedure is implemented for data delivery, through the use of non conditional smart cards. All these functions may be accomplished through a proper design of the system management, and a suitable interactive application. Results The interactive application acting as the interface between the user and the system on the TV monitor has been evaluated able to help readability and clear understanding of the contents and functions proposed. Thanks to the limited amount of data to transfer, even a Set Top Box equipped with a traditional PSTN modem may be used to support the proposed service at a basic level; more advanced features, like audio/video connection, may be activated if the Set Top Box enables a broadband connection (e.g. ADSL). Conclusions The proposed layered architecture for a remote health monitoring system can be tailored to address a wide range of needs, according with each patient’s conditions and capabilities. The system exploits the potentialities offered by Digital Television receivers, a friendly MHP interface

    NASA Technical Reports Server (NTRS)

    1972-01-01

    A ground-commanded color television assembly (GCTA) was designed for use on lunar explorations associated with NASA manned Apollo missions. The camera system as seen on Apollo 15 provided television coverage in the vicinity of the lunar module (LM) landing site, and was mounted on the lunar roving vehicle (LRV) to provide color coverage of astronaut activity and lunar topography during traverses on the surface. Remote control of the camera from earth was accomplished through the existing real-time Apollo command links. The assembly is illustrated. The configuration satisfied all anticipated requirements of the Apollo 15 mission and was fully responsive to specifications. The technical approach was based on proven designs and offered maximum mission flexibility, potential growth, and capability to withstand environmental extremes encountered on the lunar surface.

    Winett, Richard A.; Leckliter, Ingrid N.; Chinn, Donna E.; Stahl, Brian; Love, Susie Q.

    1985-01-01

    A combination of social marketing, communications, social learning (particularly modeling), and behavior analysis may provide an effective framework for behavior change via films and television. We used this approach in developing special television programs about residential energy conservation. The programs were tailored and directed to preselected middle-class homeowners (N = 150), and delivered over a public access channel of a cable TV system. The results indicated that after one program exposure (about 20 minutes), viewers adopted simple strategies modeled in the programs which led to savings of approximately 10% on their home energy use for a substantial part of the cooling and heating season. Although the potential benefits to costs of large-scale media efforts seemed great, institutional barriers for such programs were identified. Less expensive, more local programs seem more viable.

    1991-06-01

    In certain test, measurement, and research applications of CCD TV systems, the greater accuracy than usual 8-bit frame-grabbers can provide is demanded without the system being too expensive. The paper presents the concept and features of the high-precision low-cost digital CCD TV system intended for obtaining 12-bit monochrome images of immobile or relatively slow moving objects. The increase in accuracy is achieved by the specific digitization procedure -- one column per frame, which combines the benefits of a slow A/D converter with real-time TV imaging compatibility. To reduce speed restrictions on sample- and-hold circuits, a zoomed pixel read out cycle, corresponding to the pixel to be digitized, is proposed. The system provides great flexibility in choice of integration times and readout rates by means of a programmable readout sequencer, and is easily adaptable to various user demands and CCDs types.

    NASA Technical Reports Server (NTRS)

    Ruoff, C. F., Jr. (Inventor)

    1985-01-01

    A remote television viewing system employing an eye tracker is disclosed, wherein a small region of the image appears in high resolution, and the remainder of the image appears in low resolution. The eye tracker monitors the position of the viewer's line of sight. The eye tracker position data is transmitted to the remote television camera and control. Both the remote camera and television display are adapted to have selectable high-resolution and low resolution raster scan modes. The position data from the eye tracker is used to determine the point at which the high-resolution scan is to commence. The video data defining the observed image is encoded in a novel format, wherein in each data field, the data representing the position of the high resolution region of predetermined size appears first, followed by the high resolution zone video data and then the low-resolution region data. As the viewer's line of sight relative to the displayed image changes, the position of the high resolution region changes to track the viewer's line of sight.

  16. Television Viewing Does Not Have to Be Sedentary: Motivation to Participate in a TV Exercise Program.

    PubMed

    Meis, Jessie J M; Kremers, Stef P J; Bouman, Martine P A

    2012-01-01

    The present study explored which underlying motivations induced people to participate in a television exercise program called "The Netherlands on the Move!-television" (NOM-tv). A cross-sectional study was carried out among 1,349 viewers of NOM-tv. The respondents completed the intrinsic motivation inventory (IMI), assessing their levels of intrinsic motivation towards participating in the NOM-tv exercises. The results showed that higher levels of intrinsic motivation (i.e. enjoying the NOM-tv exercises, feeling competent to perform this activity, and willingness to put effort into the exercises) were the most important predictive factors of more frequent participation in the NOM-tv exercises. Future screen-based interventions to reduce sedentary behavior should aim especially at encouraging people's intrinsic orientations towards physical activity in an autonomy-supportive way.

  17. Technology for Television

    NASA Technical Reports Server (NTRS)

    1986-01-01

    A project being conducted by Varian Associates, Inc. and Lewis Research Center would allow a Ultrahigh Frequency (UHF) TV station to save 50% of its electricity cost. Because UHF stations need substantially more transmitter power, an amplifying device was needed. In the early 1970's Dr. Henry Kosmahl of Lewis had developed a radiowave amplifier to improve satellite transmission. He later worked with modifying klystron transmitters, electronic vacuum tubes used to generate and amplify UHF frequencies. If Dr. Kosmahl's multistage depressed collector or MDC can be incorporated into the klystron, the magnetic field shapes of electron beams can be changed to aid the energy recovery function of the MDC.

    1982-02-01

    The Department of Defense ranges have relied on photographic instrumentation for gathering data of firings for all types of ordnance. A large inventory of cameras are available on the market that can be used for these tasks. A new set of optical instrumentation is beginning to appear which, in many cases, can directly replace photographic cameras for a great deal of the work being performed now. These are television cameras modified so they can stop motion, see in the dark, perform under hostile environments, and provide real time information. This paper discusses techniques for modifying television cameras so they can be used for motion analysis.

  7. How older people watch television. Telemetric data on the TV use in Germany in 1996.

    PubMed

    Grajczyk, A; Zöllner, O

    1998-01-01

    This study has been prompted by the relatively small body of knowledge on the media use of the elderly. The aim of this study was to show how people 50 years and older use the medium television in Germany. Therefore, the 1996 television usership data collected in a representative 'peoplemeter' panel of about 4,800 German television households have been surveyed, processed and analyzed using standard audience research software. In 1996, Germans 50 years and above watched on average 233 min television per day. The older a person, the longer he or she watches television. Individuals 65 years and older watch television for 253 min per day. This subgroup appears to comprise the most intensive users of the medium. Men 65 years and above may be depicted as the heaviest weekend TV watchers, older women as the medium's closest followers from Monday to Friday. Television program broadcast late in the afternoon and early in the evening have by far the best chances to be chosen by seniors. The affinity of the elderly for the medium can be explained by its potential for offering entertainment, information, and companionship, being a substitute for primary interpersonal communication, a tool for structuring time patterns and keeping up the rhythms of long-established everyday rituals. On the one hand, television can be a 'lifeline' and a 'window to the outside world' for people with little opportunity for direct, unmediated social contact, thus possibly raising their satisfaction of life. On the other hand, prolonged TV use may be seen as an indicator for the degree of loneliness and neglect of the elderly. PMID:9592692

    2008-04-01

    Our Institute of Physics exposes since 1980 didactical exhibitions of holography in Brazil where nice holograms are shown altogether with basic experiments of geometric and wave optics. This experiments lead to the understanding of the phenomenon of images of an ample way. Thousands of people have been present at them, in their majority of the Universidade Estadual de Campinas, where since 2002 they have taken the format of a course without formal evaluation. This way the exhibition has been divided in four modules, in each one of them are shown different holograms, experiments of optics and applications of diffractive images with white light developed in the Institute of Physics. The sequence of the learning through the modules begins with the geometric optics, later we explain the wave optics and finally holography. The phenomenon of the diffraction in daily elements is shown experimentally from the beginning. As well as the application of the holographic screens in white light: the television images that appear in front of the screen and the spectator can try to experience the reality illusion. Put something so exclusive (that only exists in the laboratory) to the public is a way to approximate the persons to an investigation in course. The vision of images that seem to be of holograms, but in movement, and size of until a square meter completes this exhibition of an exclusive way in the world.

  15. Violence on Canadian Television Networks

    PubMed Central

    Paquette, Guy

    2004-01-01

    Introduction Over the past twenty years, the question of the effects of violence on television has figured prominently in public opinion and hundreds of studies have been devoted to this subject. Many researchers have determined that violence has a negative impact on behavior. The public, broadcasters and political figures all support the idea of reducing the total amount of violence on television - in particular in shows for children. A thousand programs aired between 1993 and 2001 on major non-specialty television networks in Canada were analyzed: TVA, TQS, as well as CTV and Global, private French and English networks, as well as the English CBC Radio and French Radio-Canada for the public networks. Method The methodology consists of a classic analysis of content where an act of violence constitutes a unit of analysis. Results The data collected revealed that the amount of violence has increased regularly since 1993 despite the stated willingness on the part of broadcasters to produce programs with less violence. The total number of violent acts, as well as the number of violent acts per hour, is increasing. Private networks deliver three times more violence than public networks. Researchers have also noted that a high proportion of violence occurs in programs airing before 21:00 hours, thereby exposing a large number of children to this violence. Conclusion Psychological violence is taking on a more significant role in Canadian Television. PMID:19030148

    Anand, Vibha; Downs, Stephen M; Bauer, Nerissa S; Carroll, Aaron E.

    2014-01-01

    Background Early TV viewing has been linked with maternal depression and has adverse health effects in children. However it is not known how early TV viewing occurs. We evaluated the prevalence at which parents report television (TV) viewing for their children if asked in the first two years of life and whether TV viewing is associated with maternal depression symptoms. Methods Using a cross-sectional design, we evaluated TV viewing in children 0 – 2 years of age in 4 pediatric clinics in Indianapolis, IN between January 2011 and April 2012. Families were screened for any parental report of depression symptoms (0 – 15 months) and for parental report of TV viewing (before 2 years of age) using a computerized clinical decision support system (CDSS) linked to the patient’s electronic health record (EHR). Results There were 3,254 children in the study. By parent report 50% of children view TV by 2 months of age, 75% by 4 months of age and 90% by 2 years of age. Complete data for both TV viewing and maternal depression symptoms were available for 2,397 (74%) of children. In regression models, the odds of parental report of TV viewing increased by 27% for each additional month of child’s age (OR: 1.27, CI: 1.25 – 1.30, p < 0.001). The odds of TV viewing increased by almost half with parental report of depression symptoms (OR: 1.47, CI: 1.07 – 2.00, p = 0.016). Publicly insured children had three times the odds of TV viewing compared to children with private insurance (OR: 3.00, CI: 1.60 – 5.63, p = 0.001). Black children had almost four times the odds (OR: 3.75, CI: 2.70 – 5.21, p < 0.001) and White children had one and a half times the odds (OR: 1.55, CI: 1.04 – 2.30, p = 0.032) of TV viewing when compared to Latino children. Conclusions By parental report TV viewing occurs at a very young age in infancy, usually between 0 to 3 months and varies by insurance and race/ethnicity. Children whose parents report depression symptoms are especially at risk

  11. Digital coding of Shuttle TV

    NASA Technical Reports Server (NTRS)

    Habibi, A.; Batson, B.

    1976-01-01

    Space Shuttle will be using a field-sequential color television system for the first few missions, but the present plans are to switch to a NTSC color TV system for future missions. The field-sequential color TV system uses a modified black and white camera, producing a TV signal with a digital bandwidth of about 60 Mbps. This article discusses the characteristics of the Shuttle TV systems and proposes a bandwidth-compression technique for the field-sequential color TV system that could operate at 13 Mbps to produce a high-fidelity signal. The proposed bandwidth-compression technique is based on a two-dimensional DPCM system that utilizes temporal, spectral, and spatial correlation inherent in the field-sequential color TV imagery. The proposed system requires about 60 watts and less than 200 integrated circuits.

    In this research, image analysis was used to optimize the visual output of a traditional Closed Circuit Television (CCTV) magnifying system and a head-mounted display (HMD) for people with low vision. There were two purposes: (1) To determine the benefit of using an image analysis system to customize image quality for a person with low vision, and (2) to have people with low vision evaluate a traditional CCTV magnifier and an HMD, each customized to the user's needs and preferences. A CCTV system can electronically alter images by increasing the contrast, brightness, and magnification for the visually disabled when they are reading texts and pictures. The test methods was developed to evaluate and customize a magnification system for persons with low vision. The head-mounted display with CCTV was used to obtain better depth of field and a higher modulation transfer function from the video camera. By sensing the parameters of the environment (e.g., ambient light level, etc.) and collecting the user's specific characteristics, the system could make adjustments according to the user's needs, thus allowing the visually disabled to read more efficiently.

  3. Overview of FTV (free-viewpoint television)

    NASA Astrophysics Data System (ADS)

    Tanimoto, Masayuki

    2010-07-01

    We have developed a new type of television named FTV (Free-viewpoint TV). FTV is the ultimate 3DTV that enables us to view a 3D scene by freely changing our viewpoints. We proposed the concept of FTV and constructed the world's first real-time system including the complete chain of operation from image capture to display. FTV is based on the rayspace method that represents one ray in real space with one point in the ray-space. We have developed ray capture, processing and display technologies for FTV. FTV can be carried out today in real time on a single PC or on a mobile player. We also realized FTV with free listening-point audio. The international standardization of FTV has been conducted in MPEG. The first phase of FTV was MVC (Multi-view Video Coding) and the second phase is 3DV (3D Video). MVC was completed in May 2009. The Blu-ray 3D specification has adopted MVC for compression. 3DV is a standard that targets serving a variety of 3D displays. The view generation function of FTV is used to decouple capture and display in 3DV. FDU (FTV Data Unit) is proposed as a data format for 3DV. FTU can compensate errors of the synthesized views caused by depth error.

    1998-04-01

    With the new light valve technologies and availability of international broad-band communication channels high-end large screen TV projection is a highly growing contribution to the multi-media world of today. The exciting story already started 58 years ago with the invention of the EIDOPHOR diffractive oil light modulator. The long way to turn electronic cinema into a reality triggered novel applications, e.g. teleconferencing and real time surgery transmissions at universities. Several technical approaches of spatial light modulation were tried, and finally several different solutions are feasible to provide video projectors, meeting the requirements of the different display applications of today and tomorrow. The technical history is reviewed and the limitations and feasibilities of new technologies are presented in respect to existing and new applications.

  19. Constrained TV-minimization image reconstruction for industrial CT system

    NASA Astrophysics Data System (ADS)

    Chen, Buxin; Yang, Min; Zhang, Zheng; Bian, Junguo; Han, Xiao; Sidky, Emil; Pan, Xiaochuan

    2014-02-01

    In this work, we investigate the applicability of the constrained total-variation (TV)-minimization reconstruction method to industrial CT system. In general, industrial CT systems have the same principles of imaging process with clinical CT systems, but different imaging objectives and evaluation metrics. Optimization-based image reconstruction methods have been actively developed to meet practical challenges and extensively tested for clinical CT systems. However, the utility of optimization-based reconstruction methods is task-specific and not necessarily transferrable among different tasks. In this work, we adopt constrained TV-minimization programs together with adaptive-steepest-descent-projection-ontoconvex-sets (ASD-POCS) algorithm for reconstructing images from data of a concrete sample collected using a laboratory industrial CT system developed for non-destructive evaluation. Our results, compared to those reconstructed from FBPbased algorithm, suggest that the constrained TV-minimization program combined with ASD-POCS algorithm can yield images with comparable or improved visual quality and achieve equivalent or better imaging objectives over the currently used FBP-based algorithm under dense sampling data condition.

    Senoh, Takanori; Wakunami, Koki; Ichihashi, Yasuyuki; Sasaki, Hisayuki; Oi, Ryutaro; Yamamoto, Kenji

    2014-11-01

    A holographic TV system based on multiview image and depth map coding and the analysis of coding noise effects in reconstructed images is proposed. A major problem for holographic TV systems is the huge amount of data that must be transmitted. It has been shown that this problem can be solved by capturing a three-dimensional scene with multiview cameras, deriving depth maps from multiview images or directly capturing them, encoding and transmitting the multiview images and depth maps, and generating holograms at the receiver side. This method shows the same subjective image quality as hologram data transmission with about 1/97000 of the data rate. Speckle noise, which masks coding noise when the coded bit rate is not extremely low, is shown to be the main determinant of reconstructed holographic image quality.

  3. The influence of television on cultural values -- with special reference to Third World countries.

    PubMed

    Goonasekera, A

    1987-01-01

    In focusing on the influence of television on cultural values, particularly in third world countries, the discussion covers the impact of the technology of communication on cultural values, the impact of existing, that is traditional, cultural values on television, and the impact of television programs on cultural values. It is not a problem to set up a television transmitting station in any third world country; the hardware is manufactured in developed countries and assembled in a third world country by technicians of the television manufacturing company. The key question is whether the third world country that has acquired this modern piece of technology can put it into operation run it. The operation of a modern television station calls for 3 types of professionals: engineers and technicians, television journalists and producers, and managers and administrators. Consequently, if the host country is to benefit from this transfer of technology it needs to have a community of modern professionals. Also, for a culture to successfully utilize television, it is helpful if the other media of communication are developed. In sum, at the time of the introduction of television in third world countries, such countries should possess an advanced sector of education and mass media which could form the basis for initiating the multiplier effect for which television has the potential. When introducing television to a third world country, one further needs to be aware of the impact that traditional values may have on the utilization of this medium. It can work to entrench traditional inequities in social relationships in the name of cultural uniqueness, and from the perspective of disadvantaged minority groups it could be a form of "cultural imperialism." Thus, when introducing television, the governments of these countries need to consider fostering a set of values and norms that could assist in the modernization of these countries. These should be values that promote human

    SciTech Connect

    Herndon, J.N.; Kring, C.T.; Rowe, J.C.

    1986-01-01

    The Consolidated Fuel Reprocessing Program at Oak Ridge National Laboratory has been developing advanced techniques for remote maintenance of future US fuel reprocessing plants. The developed technology has a wide spectrum of application for other hazardous environments. These efforts are based on the application of teleoperated, force-reflecting servomanipulators for dexterous remote handling with television viewing for large-volume hazardous applications. These developments fully address the nonrepetitive nature of remote maintenance in the unstructured environments encountered in fuel reprocessing. This paper covers the primary emphasis in the present program; the design, fabrication, installation, and operation of a prototype remote handling system for reprocessing applications, the Advanced Integrated Maintenance System.

  1. Characterization of photocathode dark current vs. temperature in image intensifier tube modules and intensified televisions

    NASA Astrophysics Data System (ADS)

    Bender, Edward J.; Wood, Michael V.; Hart, Steve; Heim, Gerald B.; Torgerson, John A.

    2004-10-01

    Image intensifiers (I2) have gained wide acceptance throughout the Army as the premier nighttime mobility sensor for the individual soldier, with over 200,000 fielded systems. There is increasing need, however, for such a sensor with a video output, so that it can be utilized in remote vehicle platforms, and/or can be electronically fused with other sensors. The image-intensified television (I2TV), typically consisting of an image intensifier tube coupled via fiber optic to a solid-state imaging array, has been the primary solution to this need. I2TV platforms in vehicles, however, can generate high internal heat loads and must operate in high-temperature environments. Intensifier tube dark current, called "Equivalent Background Input" or "EBI", is not a significant factor at room temperature, but can seriously degrade image contrast and intra-scene dynamic range at such high temperatures. Cooling of the intensifier's photocathode is the only practical solution to this problem. The US Army RDECOM CERDEC Night Vision & Electronic Sensors Directorate (NVESD) and Ball Aerospace have collaborated in the reported effort to more rigorously characterize intensifier EBI versus temperature. NVESD performed non-imaging EBI measurements of Generation 2 and 3 tube modules over a large range of ambient temperature, while Ball performed an imaging evaluation of Generation 3 I2TVs over a similar temperature range. The findings and conclusions of this effort are presented.

  5. Fingerprinting Codes for Internet-Based Live Pay-TV System Using Balanced Incomplete Block Designs

    NASA Astrophysics Data System (ADS)

    Hou, Shuhui; Uehara, Tetsutaro; Satoh, Takashi; Morimura, Yoshitaka; Minoh, Michihiko

    In recent years, with the rapid growth of the Internet as well as the increasing demand for broadband services, live pay-television broadcasting via the Internet has become a promising business. To get this implemented, it is necessary to protect distributed contents from illegal copying and redistributing after they are accessed. Fingerprinting system is a useful tool for it. This paper shows that the anti-collusion code has advantages over other existing fingerprinting codes in terms of efficiency and effectivity for live pay-television broadcasting. Next, this paper presents how to achieve efficient and effective anti-collusion codes based on unital and affine plane, which are two known examples of balanced incomplete block design (BIBD). Meanwhile, performance evaluations of anti-collusion codes generated from unital and affine plane are conducted. Their practical explicit constructions are given last.
