  1. 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.

  2. Two-way cable television system characterization

    NASA Astrophysics Data System (ADS)

    Schauer, Paul T.

    1995-11-01

    This presentation is a report of the testing activities of the CableLabs Network Integrity Working Group. The working group consisted of several CableLabs member companies which conducted rf analog and digital bit-error testing at five CATV networks in the U.S. and Canada. The purpose of the working group was to measure the reliability and availability of the contemporary CATV network as specified by traditional switched access telephony performance parameters. Transmission data was collected for both forward and reverse (sub- split) paths of the rf broadband network, in both traditional and hybrid fiber/coax architectures, and for baseline and controlled variation events. The basic premise of this testing was to ascertain which cable television network elements adversely affected transmission of a 'generic' digital communications system and how they can be managed or controlled. The digital transmission utilized in the test was a QPSK modulated, T-1 rate (1.544 Mbit/second), modem without error correction. The intent was not to derive the necessary modulation technique and error correction scheme to properly operate in every cable television system, but rather to determine the principal sources of impairments existing in these networks and deduce corrective measures. The full report of the Network Integrity Working Group is published by CableLabs, Inc., and is titled, 'Two-Way Cable Television System Characterization -- Final Report', April 1995.

    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.

  11. Carrier-interference ratios for frequency sharing between frequency-modulated amplitude-modulated-vestigial-sideband television systems

    NASA Technical Reports Server (NTRS)

    Barnes, S. P.; Miller, E. F.

    1978-01-01

    For just perceptible interference, an FM television signal interfering with another FM television signal must have an average signal power that is 26 to 37 db less than the wanted signal power. For an AM-VSB television signal interfering with an FM television signal, the AM-VSB television's sync peak average power must be 18 to 31 db below the FM television signal's average power. Also, when an FM television signal interferes with an AM-VSB signal, the average signal power of the FM signal should be 56 to 59 db below the sync peak average power of the AM-VSB television signal. The range of power ratios occur as a result of different TV scenes used in the tests and different FM-signal frequency deviations used. All tests were performed using 525 line, system M, color-television signals.

  12. Carrier - Interference ratios for frequency sharing between satellite systems transmitting frequency modulated and digital television signals

    NASA Technical Reports Server (NTRS)

    Barnes, S. P.

    1979-01-01

    As the data rates required for digitally encoded television are reduced, satellite systems employing the transmission of digitally encoded television will become attractive. It is likely that television transmitted in this format will be adjacent to or in the same frequency band as television transmissions in other modulation formats, so a knowledge of carrier to interference power ratios as a function of assessed picture quality will be required for frequency sharing between these different modulation formats. This paper presents the results of subjective and quantitative tests describing the results of interference to a particular digital television system from a frequency modulated (FM) television system, and for interference to an FM television system from a digital television system.

    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.

  3. 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.

  7. TVS: An Environment For Building Knowledge-Based Vision Systems

    NASA Astrophysics Data System (ADS)

    Weymouth, Terry E.; Amini, Amir A.; Tehrani, Saeid

    1989-03-01

    Advances in the field of knowledge-guided computer vision require the development of large scale projects and experimentation with them. One factor which impedes such development is the lack of software environments which combine standard image processing and graphics abilities with the ability to perform symbolic processing. In this paper, we describe a software environment that assists in the development of knowledge-based computer vision projects. We have built, upon Common LISP and C, a software development environment which combines standard image processing tools and a standard blackboard-based system, with the flexibility of the LISP programming environment. This environment has been used to develop research projects in knowledge-based computer vision and dynamic vision for robot navigation.

  9. 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.

    This work develops and demonstrates a double sideband with optical carrier suppression (DSBCS) modulation scheme for a hybrid wireless and cable television system based on a phase modulator (PM) and a polarization beam splitter (PBS). A carrier suppression ratio greater than 20 dB is achieved between two sidebands. In addition, the values of carrier-to-noise ratio, composite second-order and composite triple beat in various channels after 25 km of transmission are higher than the threshold value, and the power penalty of microwave signal in back-to-back and 25 km transmission perform well. Additionally, the constellation diagram of upstream signal is successfully recovered. Above results demonstrate that the proposed scheme is highly promising for practical applications.

    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.

    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.

    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

    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

    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

    1975-01-01

    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.

    During 1985 Bristish Telecom commenced the installation of a number of cable television systems in the United Kingdom. One of these systems, in Westminster, London, is of the Switched Star type, developed by the British Telecom Research Laboratories. The network comprises optical fiber cable between the head-end and the cabinet-mounted switch, and coaxial cable between the switch and the customer. A number of new outside plant products have been developed to meet the special requirements of the Westminister installation. This earlier work, together with the experience gained from the installation of optical fibers in the British Telecom trunk and junction networks, formed an ideal basis for evolving the line plant necessary to enable BT to introduce singlemode optical fiber into the local network. A range of cables is being developed by UK companies, suitable for installing in the harsh environment of the local network. Joint organizers and flexibility nodes are being introduced, both for underground application and for within the exchange and customer's premises. In addition blown-fiber techniques are being used to introduce fiber into these networks.

    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

    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.

    2015-08-01

    Exemplifying a real person in news stories has become a popular journalistic technique to describe an event or issue. With the frequent appearance of medical news reports in local television in recent years, this news presentation style is widely believed to help audiences better engage in and understand complex medical information and to influence their perceptions and judgments. In terms of television news coverage of medical advances, this study investigates how audiences respond to embedded human examples (mainly patients who experience benefits from the advances) and to overall news stories, and how such responses are related to their perception of portrayed medical advances. The experimental results indicate that news stories with a human example were more likely to intensify the audience's positive emotions than those without, which in turn influenced favorable perceptions of the described medical advance. In addition, the extent to which the audience identified with a human example (in particular, sympathy) mediated the relationship between the audience's involvement in the news story and its perception of the portrayed medical advance.

    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.

    Since the development of high-brightness blue and green LEDs, the use of outdoor commercial LED displays has been increasing. Because of their high brightness, good visibility, and long-term durability to the weather, LED displays are a preferred technology for outdoor installations such as stadiums, street advertising, and billboards. This paper deals with a large stereoscopic full-color LED display by use of a parallax barrier. We discuss optimization of the viewing area, which depends on LED arrangements. An enlarged viewing area has been demonstrated by using a 3-in-1 chip LED panel that has wider black regions than ordinary LED lamp cluster panels. We have developed a real-time measurement system of a viewer's position and utilized the measurement system for evaluation of performance of the different designs of stereoscopic LED displays, including conventional designs to provide multiple perspective images and designs to eliminate pseudoscopic viewing areas. In order to show real-world images, it is necessary to capture stereo-images, to process them, and to show in real-time. We have developed an active binocular camera and demonstrated the real-time display of stereoscopic movies and real-time control of convergence.

  14. Pulsed illumination, closed circuit television system for real-time viewing of unsteady (> 1 micros) events.

    PubMed

    Marden, W W; Steinberger, R L; Bracco, F V

    1978-10-01

    A pulsed illumination closed circuit television system is described whereby fast (times <33 ms), unsteady events can be observed in real time. A low-power helium-neon laser beam is modulated to send a short duration light pulse through the unsteady test medium. The light is refracted according to the instantaneous optical properties of the medium. The refracted light travels to a solid state television camera, known as a charge injection device (CID), in which the sensor array is charged within microseconds. The scanning of the charged array then follows, requiring the standard 33 ms for information transfer to video tape and a TV monitor. The image is thus formed during the laser pulse duration (which presently is 10 to 100 micros, but shorter duration pulses are possible with more powerful lasers), but no more than one image every 33 ms can be observed and recorded. Thus this method is particularly suited for the investigation of high frequency periodic events in which one can observe both a single image, or an ensemble average of as many as 100 images, occurring at corresponding times in different cycles. The reported applications include the recording of steady and transient propane torch flames, of the transient fuel injection process in a motored internal combustion engine, and of the propagation of a flame under firing conditions in the engine. In the shadowgraph and Schlieren modes the method is particularly suited for application to periodic combustion events such as those occurring in internal combustion engines. The method then presents the following advantages over high-speed filming (> 3000 pictures/s); real-time observation and recording of chamber events at any crankangle; real-time observation and recording of the effects of changes in the engine variables (speed, load, spark timing, injection pressure and duration, chamber swirl, etc.) on the combustion events; real-time observation and recording of ensemble averages and cycle-to-cycle variations

    NASA Astrophysics Data System (ADS)

    Kozak, P. M.

    2014-07-01

    The universal semi-empirical method for the photometry of low-light meteors is proposed. The method was developed for the photometrical measurements and reductions of meteor images obtained with the observational television systems of super-isocon type, which are well-known due to their non-linearity of the response onto the input signal, and afterimages from the dynamical objects in a television frame, which are not removable because of construction features of the systems. Semi-empirical method was displayed in the fact that the photometrical dependences of the television system for the moving and stationary objects were investigated by means of the test with photographing of the star sky with the camera, which was rotating with different angular velocities including zero velocity (i.e. when the camera was in the stationary state). Basing on the obtained results the calibrating curve was plotted, and light curves of two low-light meteors of 5-6 magnitude were calculated. The proposed method is universal and can be used for the photometrical processing of data obtained with any television or video system.

    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.

    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.

    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.

  2. HELITRAK: A helicopter-tracking receiver system for television outside broadcast links

    NASA Astrophysics Data System (ADS)

    Gandy, C.

    1992-11-01

    Helicopters are used by BBC Television for certain live outside broadcasts which require an elevated platform for a camera or for a radio-link mid-point repeater. Video signals are communicated from the helicopter to the ground using microwave radio links, and the signals are received by a narrow-beamwidth dish antenna which must be kept pointing accurately towards the aircraft. In the past, this receiving antenna has always been pointed manually, but in some circumstances the performance of the radio links can be limited by the ability of an operator to keep the antenna on track. Such a limitation can be avoided by using an automatic tracking system; this report describes the approach taken by the Research Department to develop the 'HELITRAK' tracking receiver system. Unlike some of the proprietary counterparts, this is a set of equipment which facilitates automatic tracking when applied to an existing radio-link receiver. It is specially tailored to the requirements of a video transmission system and needs only one conventionally transmitted radio-link signal. It has the potential to increase the reliability and the maximum range of helicopter links, and to improve operational efficiency. The text covers the development of the tracking system, detailing the operational requirements and the design options. The system uses a novel method of tracking by detecting the direction of incoming RF signals, using higher-order mode synthesis in the antenna feed. Operational experience (from use in live outside broadcasts) and system limitations are noted, and areas for further improvements are identified.

  4. Digital pseudo-analogue satellite TV transmission system

    NASA Astrophysics Data System (ADS)

    Tomlinson, M.; Ward, C.; Rendle, M.

    1986-07-01

    With the advent of high-speed digital signal processing circuits, it is now practicable to transmit television signals by satellite using a variety of digitally derived modulation techniques. By using the concept of E(s)/N(0), the ratio of the energy needed to transmit each sample to the noise spectral density, several different signal formats are critically compared in the paper. It is shown that the wide bandwidths associated with high-definition television may be supported by relatively narrow transponder bandwidths through the use of signal formats using phase-modulated discrete symbols. Furthermore, the bandwidth efficiency is shown to be better than the classical technique of frequency modulation for satellite TV transmission. A digitally implemented system is described and results are given of successful satellite tests using the Eutelsat F1 satellite and the Westar V satellite.

  19. 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

    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.

    Tucker, L A

    1987-10-01

    The purpose of this study was to determine the extent to which multiple health and lifestyle variables differ among 406 adolescent males classified according to average duration of daily television viewing. Cattell's 16PF Questionnaire, Form C, and Rosenberg's Self-Esteem Scale were employed to assess psychological health, and the Physical Performance Test for California was used to measure six dimensions of physical fitness. Participants also completed a questionnaire requesting general demographic data, and information regarding lifestyle and average amount of time spent watching television per day. Results indicated that the well-being of the boys was related significantly to the extent of television viewing. Light television viewers were more physically fit, emotionally stable, sensitive, imaginative, outgoing, physically active, self-controlled, intelligent, moralistic, college bound, church oriented, and self-confident than their counterparts, especially heavy television viewers. Furthermore, light television viewers were less troubled, frustrated, and shrewd, and used drugs less frequently, particularly alcohol, than moderate and heavy television watchers, especially the latter.

    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.

  1. 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.

    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.

    1981-02-01

    Digital transmission and signal encoding methods with redundancy reduction were investigated for a television downlink from a satellite to the home receiver as an alternative method to analog FM transmission, the main criteria being bandwidth, carrier to noise ratio, picture quality and equipment costs at the receiving end. Digital PCM encoded and four phase shift key modulated transmission with a bandwidth of 22.4 MHz, giving very good picture quality, is proposed as advantageous for signal reception with small antennas. An alternative two channel transmission with 27 MHz bandwidth, using a higher order modulation method, is discussed. However, this proposal calls for a higher receiving antenna performance and is thus suitable for community antenna systems only.

    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.

  10. Television image of a large upward electrical discharge above a thunderstorm system.

    PubMed

    Franz, R C; Nemzek, R J; Winckler, J R

    1990-07-01

    An image of an unusual luminous electrical discharge over a thunderstorm 250 kilometers from the observing site has been obtained with a low-light-level television camera. The discharge began at the cloud tops at 14 kilometers and extended into the clear air 20 kilometers higher. The image, which had a duration of less than 30 milliseconds,resembled two jets or fountains and was probably caused by two localizd electric charge concentrations at the cloud tops. Large upward discharges may create a hazard for aircraft and rocket launches and, by penetrating into the ionosphere, may initiate whistler waves and other effects on a magnetospheric scale. Such upward electrical discharges may account for unexplained photometric observations of distant lightning events that showed a low rise rate of the luminous pulse and no electromagnetic sferic pulse of the type that accompanies cloud-to-earth lightning strokes. An unusually high rate of such photometric events was recorded during the night of 22 to 23 September 1989 during a storm associated with hurricane Hugo.

    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.

    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.

    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

    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.

    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.

  20. 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.

    2009-01-01

    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.

    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.

    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.

  6. Sitting and Television Viewing

    PubMed Central

    Kline, Christopher E.; Youngstedt, Shawn D.; Phillips, Barbara; Tulio de Mello, Marco; Hirshkowitz, Max

    2015-01-01

    BACKGROUND: Excess sitting is emerging as a novel risk factor for cardiovascular disease, diabetes, mental illness, and all-cause mortality. Physical activity, distinct from sitting, is associated with better sleep and lower risk for OSA, yet relationships among sitting behaviors and sleep/OSA remain unknown. We examined whether total sitting time and sitting while viewing television were associated with sleep duration and quality, OSA risk, and sleepiness. METHODS: The 2013 National Sleep Foundation Sleep in America Poll was a cross-sectional study of 1,000 adults aged 23 to 60 years. Total sitting time, time watching television while sitting, sleep duration and quality, OSA risk, and daytime sleepiness were assessed. RESULTS: After adjusting for confounding factors (including BMI and physical activity), each additional hour per day of total sitting was associated with greater odds of poor sleep quality (OR [95% CI] = 1.06 [1.01, 1.11]) but not with other sleep metrics (including sleep duration), OSA risk, or daytime sleepiness. For television viewing while sitting, each additional hour per day was associated with greater odds of long sleep onset latency (≥ 30 min) (OR = 1.15 [1.04, 1.27]), waking up too early in the morning (OR = 1.12 [1.03, 1.23]), poor sleep quality (OR = 1.12 [1.02, 1.24]), and “high risk” for OSA (OR = 1.15 [1.04, 1.28]). Based upon an interaction analysis, regular physical activity was protective against OSA risk associated with television viewing (P = .04). CONCLUSIONS: Excess sitting was associated with relatively poor sleep quality. Sitting while watching television was associated with relatively poor sleep quality and OSA risk and may be an important risk factor for sleep disturbance and apnea risk. PMID:25633255

    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.

  16. 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.

  17. HDTV: A chance to enhance television colorimetry

    NASA Astrophysics Data System (ADS)

    Roberts, A.

    The development of a new high definition television (HDTV) system for use within Europe has provided a unique opportunity to depart from standard television colorimetry and coding which has been used worldwide since color television began. All television systems in operation at present use coding systems which allow substantial proportions of the perceived luminance to travel via narrow band coloring channels, thus reducing luminance detail in colored areas. This is known as the failure of constant luminance. Also, the gamut of colors reproducible by existing television systems and equipment does not do justice to saturated colors encountered in real life. A new system was devised which greatly expands the color gamut than can be reproduced, and uses constant-luminance coding to avoid loss of detail in colored areas. This has been achieved without compromising compatibility with the existing television system; the proposed system produces signals which can be decoded by a conventional receiver while still producing satisfactory color reproduction and sharpness. The enlarged color gamut of the proposed system will allow future displays to provide continuing improvements in color performance as new types of display (e.g., laser projectors) are developed with increasingly saturated display primaries. The constant-luminance decoding receiver is necessarily more complex than a conventional receiver, and may not be achievable without resort to digital processing in the domestic receiver. Studio monitoring using constant-luminance decoding could also be prohibitive in both cost and complexity. To overcome both of these problems, a modified form of standard decoder has been developed; it almost completely removes the residual color errors due to compatible decoding while retaining the color sharpness advantage of constant-luminance coding.

    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.

    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.

    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.

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

    SciTech Connect

    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.

    Much attention has been paid to the amount of time Americans spend watching television. Cultivation theory has been important in exploring behavioral effects of television viewing for many years. However, psychosocial health has received much less scrutiny in relation to television viewing time. This investigation examined the hypotheses that television-free individuals and viewers adhering to the American Academy of Pediatrics (AAP) recommendations (up to 2 hr of viewing per day) would display a more positive psychosocial health profile when compared with more frequent television viewers. Results confirmed the hypothesis for women, but not for men. Our analysis showed that moderate television viewing, as defined by the AAP, provides a similar relation with psychosocial health as being television-free. Results are discussed in a cultivation theory framework. PMID:15855072

    1987-08-01

    We developed a mobile closed-circuit television cart for resident and staff presentations at rounds, and fluorescein angiography and pathology conferences. The system, operated without special training, permits presentation of x-rays, CT scans, visual fields, echographic and electrophysiologic tracings, fluorescein angiograms, color photographs, 35 mm slides, and printed text on standard closed-circuit television monitors. For pathology conferences, gross dissections, slides of whole eyes and standard high power microscopic fields may be shown. The cart can be assembled using readily available components for the same cost as a stand-alone glass slide projector. Mounted on wheels, the entire unit may be moved to any location equipped with closed circuit television monitors. Because the cart can be used to teach nearly every medical discipline, the cost of construction can be shared by a number of departments.

    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%.

    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

    1988-01-01

    Given its widespread availability and impact on social values, television is expected to play an important role in China's modernization drive. Necessary to this process is a detailed analysis of the framework in which the technical aspects of television's development are related to political, economic, telecommunications, and social factors. To facilitate this analysis, a Delphi survey was conducted in 1986 as was a cross-impact analysis assisted by computer modelling. Entitled "Future Development of Chinese Television, 1986-2001," the Delphi survey sought to provide decision makers with operationally meaningful assistance in the form of information and analysis. The responses from experts suggested that, if economic growth can be sustained over the next 5 years, telecommunications development will receive top priority in state planning. Cross-impact analysis helps to clarify and promote better understanding of the complex relationships among future events and trends. This analysis tended to confirm the hypothesis that a nongovernmental television station is unlikely to emerge before 1991. Crucial to the success of any television policy (such as cable television service or videotext systems) is legislative support. The appearance of a nongovernmental television station would have a considerable impact on the private sector in China and lead to competition in programming quality, attracting audiences, and further commercialization. While the future development of Chinese television is dependent on economic factors such as purchasing power and the quality of life, its development can thus also be expected to exert a strong influence on economic life.

    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.

Most research has focused analysis on a few weeks of coverage of major stories like the gas leak at Bhopal, the Three Mile Island nuclear accident, or the Mount St. Helen's eruption. To advance the research into television coverage of environmental risk, an analysis has been made of all environmental risk coverage by the network nightly news broadcasts for a period of more than two years. Researchers have analyzed all environmental risk coverage-564 stories in 26 months-presented on ABC, CBS, and NBC's evening news broadcasts from January 1984 through February 1986. The quantitative information from the 564 stories was balanced by a more qualitative analysis of the television coverage of two case studies-the dioxin contamination in Times Beach, Missouri, and the suspected methyl isocyanate emissions from the Union Carbide plant in Institute, West Virginia. Both qualitative and quantitative data contributed to the analysis of the role played by experts and environmental advocacy sources in coverage of environmental risk and to the suggestions for increasing that role.

  4. 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

    In February and March 1989 the Phobos 2 spacecraft took 37 television images of Phobos from a distance of 190-1100 km. The data are being used to update the three-dimensional model of Phobos, to provide improved determinations of its density and orbital dynamics, and to study its surface color, composition, and texture. Preliminary findings are presented here which include different integrated photometric behavior in visible and near-infrared bands, observation of a region immediately west of Stickney which is relatively free of large grooves, the prevalence of bright rims on grooves and younger craters, and low bulk density.

  7. Face recognition system for set-top box-based intelligent TV.

    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

    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.

    2001-01-01

    The nation's hospitals and medical centers are enjoying the legacy of TV audiences' addiction to medical dramas. Cable television has met the challenge with documentary coverage of real live hospitals. The medium offers many benefits and few disadvantages for those marketing managers with the courage to welcome camera crews. Lynn Hopkins Cantwell is director of public relations and marketing for Children's National Medical Center, Washington, D.C., which was covered in a seven-instrument "Lifeline" documentary for the Discovery Channel. James G. Gosky is director of communications for The MetroHealth System, Cleveland, which was the subject of two installments of "Trauma: Life in th ER," produced for the Learning Channel. These marketing pros describe the myriad details they faced when their respective hospitals went "on camera." Among the key factors were good communications with all constituents, attention to detail, and follow-up. PMID:11209289

    Two girls and one boy suffered seizures caused by television and other visual stimuli from 11, 12 and 12 years of age onwards, respectively. EEG recording revealed that intermittent photic stimulation (IPS) provoked epileptiform activity. Technological progress (video games, computer, disco, car, train) has considerably increased the risk for visually-induced seizures. A comprehensive clinical history with special attention to the environmental circumstances is important. For correct diagnosis an EEG with standardised IPS is necessary. Treatment consists of avoidance of strong visual stimuli. Patients may need prophylaxis with valproic acid, which should only be withdrawn after clear reduction of the EEG response to IPS. Repeating the EEG after the dosage has been lowered will help avoiding unnecessary recurrence of seizures. PMID:12085553

    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.

  3. 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 Astrophysics Data System (ADS)

    Vishnevsky, Grigory I.; Ioffe, S. A.; Berezin, V. Y.; Rybakov, M. I.; Mikhaylov, A. V.; Belyaev, L. V.

    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.

  10. Retinally stabilized differential resolution television display

    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.

  11. 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.

  6. It's Better on TV: Does Television Set Teenagers Up for Regret Following Sexual Initiation?

    2010-01-01

    Context Approximately two-thirds of all sexually experienced teenagers in the United States say they wish they had waited longer to have sexual intercourse for the first time. Little is known, though, about why such a large proportion of teenagers express disappointment about the timing of their initial experience with sexual intercourse. Methods Using data from a national longitudinal survey of adolescents (12-17 year olds followed to ages 15-20), we tested for a prospective association between exposure to sex on television and the likelihood of regret following sexual initiation, analyzed the mediating role of shifts in sex-related outcome expectancies from pre- to post-initiation, and investigated gender differences in these relationships. Results Among males (but not females), we found that greater exposure to sexual content on television was associated with an increased likelihood of regret following sexual initiation, an association partly explained by a downward shift in males' sex-related outcome expectancies following sexual initiation. Conclusions These findings, which offer insight into the contextual factors and processes that may foster initiation regret, could be important for advancing critical decision-making by youth about sexual debut.

  16. 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.

  1. Liquid Crystal Television For Optical Correlation

    NASA Astrophysics Data System (ADS)

    Perng, Wen-Sheng; Cheng, Yih-Shyang; Chang, Ming-Wen

    1987-08-01

    In this paper, we present a newly developed hybrid multi-channel real-time pattern recognition system. Two modified commercial liquid crystal televisions are applied as a real-time incoherent to coherent image transducer and a device to produce converging wavelets with different focal positions. Taking advantages of the cross-grating nature of the LCTV screen, a multi-channel correlator becomes possible. This hybrid system has both the high processing speed of an optical system and the flexibility of an electronic system.

    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.

  3. 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.

  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

  5. Digital image processing for the rectification of television camera distortions.

    NASA Technical Reports Server (NTRS)

    Rindfleisch, T. C.

    1971-01-01

    All television systems introduce distortions into the imagery they record which influence the results of quantitative photometric and geometric measurements. Digital computer techniques provide a powerful approach to the calibration and rectification of these systematic effects. Nonlinear as well as linear problems can be attacked with flexibility and precision. Methods which have been developed and applied for the removal of structured system noises and the correction of photometric, geometric, and resolution distortions in vidicon systems are briefly described. Examples are given of results derived primarily from the Mariner Mars 1969 television experiment.

    2000-01-01

    Television viewing patterns in preschool age Hispanic children were studied in order to explore the role of TV in the establishment of early childhood health behaviors. The television viewing habits and patterns of children and parents and parental coviewing, regulation, and encouragement practices were examined. Using the dimensions of regulation and encouragement, four parental typologies were established: laissez-faire, restrictive, promotive, and selective. Children in this study watched television 3-4 hours a day, half of which consisted of viewing adult shows. This amount of time is significantly higher than the guideline of less than 2 hours a day suggested by the American Academy of Pediatrics (AAP). Relationships between television viewing, injury behaviors, risk taking, and acculturation were established and implications for primary care, school, and community health care nursing are discussed.

  20. 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
