  5. United States digital advanced television broadcasting standard

    NASA Astrophysics Data System (ADS)

    Hopkins, Robert

    1996-01-01

    A demonstration of high definition television (HDTV) was given in the United States in the early 1980s. It inspired the imagination as to what might be seen, someday, in the homes of television viewers. Now, some fifteen years later, we are on the verge of adopting a new television broadcasting standard. In the near future, the Federal Communications Commission is expected to make its final ruling on the new technology. The new standard will be 100% digital, something nobody would have guessed watching those early demonstrations. This paper briefly reviews some key technical debates. The debates were related to HDTV production standards and analog HDTV broadcasting during the 1980s. They began to shift focus in 1990 as the first digital HDTV broadcasting proposals were made public. More recently, the debates have centered on the tremendous flexibility that can be obtained with a digital broadcasting system. The Digital HDTV Grand Alliance system, that has been under study in the FCC's Advisory Committee on Advanced Television Service and documented by the Advanced Television Systems Committee, is highlighted. Current status of the technical standard is explained. To conclude, comments on the future potential of this new television broadcasting technology are offered.

    1973-01-01

    A television multiplexing system which includes a circuit that inserts a digital codes sync signal and a digital code into a video signal for identifying the channel is described. The digital sync signal and the digital coded signals are generated by a single crystal controlled clock so that they are always in synchronism with each other. In demultiplexing the signals are utilized for shifting the digital coded signals into a shift register. The shift register, in turn, activates a decoder according to the code stored in the shift register for selecting the proper recording disk or receiver for storing the video signal.

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

    NASA Technical Reports Server (NTRS)

    Nguyen, Han

    1994-01-01

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

  11. Personalization on a Peer-to-Peer Television System

    NASA Astrophysics Data System (ADS)

    Wang, Jun; Pouwelse, Johan; Fokker, Jenneke; de Vries, Arjen P.; Reinders, Marcel J. T.

    Television signals have been broadcast around the world for many decades. More flexibility was introduced with the arrival of the VCR. PVR (personal video recorder) devices such as the TiVo further enhanced the television experience. A PVR enables people to watch television programs they like without the restrictions of broadcast schedules. However, a PVR has limited recording capacity and can only record programs that are available on the local cable system or satellite receiver. This paper presents a prototype system that goes beyond the existing VCR, PVR, and VoD (Video on Demand) solutions. We believe that amongst others broadband, P2P, and recommendation technology will drastically change the television broadcasting as it exists today. Our operational prototype system called Tribler [Pouwelse et al., 2006] gives people access to all television stations in the world. By exploiting P2P technology, we have created a distribution system for live television as well as sharing of programs recorded days or months ago.

  12. Television systems for remote manipulation. [in space

    NASA Technical Reports Server (NTRS)

    Crooks, W. H.; Freedman, L. A.; Coan, P. P.

    1975-01-01

    An analytical and experimental study was conducted to specify a video system for remote manipulation in space. An operator function analysis identified two basic characteristics, work volume and element relationship, which define four manipulation tasks chosen for examination. A visual function analysis developed a set of elemental scene parameters which grouped the visual dimensions into major areas of influence. Simulation testing was conducted with a four degree-of-freedom motion frame which allowed an operator to perform the manipulation tasks. Four video systems were included in the simulation testing: a black and white and a color monoscopic system, a stereoscopic system, and a black and white two-view system. A sequential experimental plan first provided an overall analysis of the effects of tasks, scene parameters, and video systems. This was followed by a detailed experimental examination of the critical dimensions identified in the first experiment. Results are discussed in terms of a recommended TV system.

  14. 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.

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

    NASA Astrophysics Data System (ADS)

    2002-11-01

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

  4. Directly modulated cable television transport systems using negative dispersion fiber

    NASA Astrophysics Data System (ADS)

    Lu, Hai-Han; Liaw, Je-Wei; Lee, Yi-Shiuan; Tsai, Wan-Lin; Ji, Yu-Jie

    2005-03-01

    A directly modulated AM-VSB cable-television transport system using negative dispersion fiber (NDF) as the transmission medium is proposed and successfully demonstrated. Good performances of carrier-to-noise radio, composite second order, and composite triple beat were obtained over a 70-km NDF transport without optical amplification. The directly modulated laser has a positive chirp, while NDF has a negative dispersion property in the transmission fiber. This negative dispersion property compensates for the laser chirp and results in a system with better transmission performance.

  5. Television camera video level control system

    NASA Technical Reports Server (NTRS)

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

    1985-01-01

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

  6. 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.

  10. 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.

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.

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

    NASA Technical Reports Server (NTRS)

    1979-01-01

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

    Thermodynamic vent system (TVS) is employed for pressure control of propellant tanks at zero gravity. An analytical lumped parameter model is developed to predict pressure variation in an 18.09 m3 liquid hydrogen tank equipped with TVS. Mathematical simulations are carried out assuming tank is filled up to 75% volume (liquid mass equals to 945 kg) and is subjected to heat flux of 0.76 W/m2. Tank pressure controls at 165.5-172.4, 165.5-179.3 and 165.5-182.2 kPa are compared with reference to number of vent cycles, vent duration per cycle and loss of hydrogen. Analysis results indicate that the number of vent cycles significantly decreases from 62 to 21 when tank pressure control increases from 6.9 to 20.4 kPa. Also, duration of vent cycle increases from 63 to 152 and cycle duration decreases from 3920 to 3200 s. Further, the analysis result suggests that LH2 evaporation loss per day decreases from 0.17 to 0.14%. Based on the results of analysis, TVS is found effective in controlling the propellant tank pressure in zero gravity.

    2004-01-01

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

    The last few decades have witnessed the increasing dissemination of information on medical advances such as new medical treatments and prevention/diagnosis technologies through television news. To engage lay audiences with complex information, medical journalists often personalize news stories about medical advances by exemplifying individual patients and their personal experiences. This study investigates the effects of this journalistic technique, which is referred to as human interest framing, on audiences. The results of an experiment provide empirical evidence that the human interest framing of medical news stories can increase audiences' involvement in those stories and facilitate their positive perception of medical advances.

    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.

    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

    We propose and experimentally demonstrate a cable television monitoring system based on a linear-cavity fiber laser and fiber Bragg grating (FBG) sensors. The linear-cavity fiber laser comprises a hybrid amplifier with an erbium-doped fiber amplifier and a semiconductor optical amplifier, a fiber loop mirror with a polarization controller and an optical coupler as a cavity mirror, and the FBG sensors acting as another cavity mirrors. Experimental results showed the feasibility of the monitoring system with sufficient of signal-to-noise ratio over 30 dB and stable output power, and the link of cable television signals on fiber link can monitored in real time. Excellent performances of carrier-to-noise ratio after long-distance transmission are obtained for cable television applications.

    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

  7. Audience responses to television news coverage of medical advances: The mediating role of audience emotions and identification.

    PubMed

    Hong, Hyehyun

    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.

  8. The diffusion of television in India.

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

    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.

    2014-01-01

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

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

    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.

  1. Revisiting the Association Between Television Viewing in Adolescence and Contact With the Criminal Justice System in Adulthood.

    PubMed

    Schwartz, Joseph A; Beaver, Kevin M

    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.

  2. Use of the Society of Motion Picture and Television Engineers test pattern in picture archiving and communication systems (PACS)

    NASA Astrophysics Data System (ADS)

    Gray, Joel E.

    1991-05-01

    In 1985 the Society of Motion Picture and Television Engineers (SMPTE) published a Recommended Practice (RP-133) entitled Specifications for Medical Diagnostic Imaging Test Pattern for Television Monitors and Hard-copy Cameras. Since that time the SMPTE monochrome test pattern has been applied to the acceptance testing and quality control of video and image display systems, and hard-copy (film) recorders. The major features of the test pattern will be discussed along with applications and the problems demonstrated with the pattern. Furthermore, the test pattern will be used to demonstrate that color displays may exhibit only one-half of the resolution of a monochrome monitor while the display contrast (due to limited dynamic range) may be only 10 to 20 of that obtained with a monochrome display.

  3. [Children, television and violence].

    Zann, M

    2000-03-01

    The relationships between children and television are a source of heated debate. Several studies, mainly conducted in North America, have found a correlation between television violence viewing and aggressive behavior, preadolescents appearing as the most vulnerable. However, in France opinions are more nuanced and one generally considers that television-induced violence in children mainly depends upon individual and educative socio-familial factors.

  12. Optical simulations for Ambilight TV systems

    NASA Astrophysics Data System (ADS)

    Bruyneel, Filip; Lanoye, Lieve

    2012-06-01

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

    1979-01-01

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

  15. Hybrid cable television and orthogonal-frequency-division-multiplexing transport system basing on single wavelength polarization and amplitude remodulation schemes.

    PubMed

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

    2011-05-01

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

  16. Design of a video system providing optimal visual information for controlling payload and experiment operations with television

Performance measurements were made under controlled conditions and the results analyzed to permit evaluation of the relative merits (effectivity) of various TV systems. Burden factors were subsequently generated for each TV system to permit tradeoff evaluation of system characteristics against performance. For the general remote operation mission, the 2-view system is recommended. This system is characterized and the corresponding equipment specifications were generated.

  17. Children, adolescents, and television.

    PubMed

    Dietz, W H; Strasburger, V C

    1991-01-01

    As we have indicated, children's television has either a documented or probable effect on a variety of health-related behaviors in children and adolescents in the United States. Studies of cognitive development indicate that television provides a stimulus for learning and that children learn from television. The adverse effects of television appear related to both the time spent watching television and the content of the programs that are viewed. The reviewed observations suggest that a variety of initiatives are warranted to alter the time children spend watching television, the content of programs, and the types of programs for children and adolescents that are produced and broadcast. These initiatives require the development of effective techniques and materials for counseling parents, as well as continued political and legislative activities at the local and national level. We must promote the conviction that time spent in activities other than television viewing will provide our children with the values necessary to understand and interact with an increasingly complex world. Effective governmental action on behalf of children to change television will require a reaffirmation and enforcement of the Public Interest Standard. For half a century, the broadcast media have been licensed to use the airwaves in the public interest. The diversity and magnitude of the adverse effects of television on the health of children strongly suggest that the use of television has not been in the public interest. Although cable television offers multiple alternatives, less than 60% of American households receive cable. Broadcast television still represents the only alternative for 40% of American children. Substantial regulatory change by the current administration is unlikely. Therefore, legislative activity to mandate broadcast practices responsive to the needs of children appears the most appropriate national approach.

    There is presently a strong expectation for the opportunities offered by the deployment of new and sophisticated telecommunication services with increasing interactivity, ranging from distributive to highly interactive, covering heterogeneous areas, like entertainment, tourism, commercial and information. The Project AMUSE (Advanced MUltimedia SErvices to residential users), which s being carried out in the framework of the Advanced Communication Technologies and Services Programme sponsored by the European Union, is proposing effective solutions to various open issues related to the implementation and provisioning of new multimedia services. After an overview of the project and the relevant platform, the paper will introduce a description of the advanced services the project is going to provide to real residential users by means of a state-of-then-art Asynchronous Transfer Mode end-to-end infrastructure. Emphasis will be put on the outcomes of the experiences gained during the first project year, stemming from the implementation and deployment of complex multimedia services developed by means of innovative authoring tools. Particular attention will be paid to the facts and findings resulting from the activities so far performed in the Italian trial island. In particular, the role of contents provisioning and service design, as well as the monitoring of service acceptance and usability by the final users are emerging as outstanding topics, even beyond network technological issues. Finally, an outline of major unsolved problems in the area of interactive multimedia s presented.

  2. A systematic review of digital interactive television systems and their applications in the health and social care fields.

    PubMed

    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.

The program was organized to provide a forum in which researchers from industry, universities, and government could be brought together to discuss the state of knowledge in image gathering, coding, and processing methods.

  9. Television for World Understanding.

    ERIC Educational Resources Information Center

    Tyler, I. Keith

    Television will be a valuable tool in preparing people to cope with a shrinking and increasingly interdependent world. A child left to his own devices will equate "strangeness" with "danger". Television can bring a wide variety of experiences with different cultures to a child and help him to formulate an understanding of his place in the world.…

    ERIC Educational Resources Information Center

    Meyer, Timothy P.

    1973-01-01

    The question of whether violence depicted on television causes viewers to act aggressively is meaningless because it implies a simple "yes" or "no" response. Effects of mass media depend on the types of viewers and content as well as the conditions of message reception. Television violence can affect the behavior of children on some occasions.…

    PubMed

    Till, Benedikt; Truong, Florence; Mar, Raymond A; Niederkrotenthaler, Thomas

    2016-10-01

    Previous studies suggest that distorted representations of reality on television can lead to distorted perceptions of reality among viewers. In this study, 322 individuals in Austria reported their weekly television consumption and whether they believe that there is active practice of capital punishment in Austria, which has been abolished since 1968. The more television participants watched, the more likely they mistakenly believed that there is, or recently was, capital punishment in Austria, even when controlling for participants' age and education. It seems that television has the potential to influence viewers' perception and knowledge of core aspects of society.

    PubMed

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

    1990-01-01

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

    PubMed

    Zuckerman, D M; Zuckerman, B S

    1985-02-01

    Television has a major impact on children's knowledge, attitudes, and behavior. Research has demonstrated the association between television viewing and four areas: (1) children's aggressive behavior; (2) racial and sex-role stereotypes; (3) decreased interest in reading and school activities; and (4) poorer health habits and attitudes. Methodological limitations make it difficult to draw firm conclusions about a causal relationship between television viewing and children's behavior. Representative studies in these four areas are reviewed, important methodological concerns are pointed out, and conclusions from the research findings are drawn. The implications of the data for pediatricians and other health professionals are discussed.

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

    PubMed

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

    2012-08-20

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

    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.

    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.

    1986-01-01

    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.

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

    PubMed

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

    1990-07-06

    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.

  10. Television and children's executive function.

    PubMed

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

    2015-01-01

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

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

    2014-01-01

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

    1972-01-01

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

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

    NASA Astrophysics Data System (ADS)

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

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

    Pervasive change is near. Among the central elements of this change will be digital interactive television. It is generally thought that interactive television can have a profound beneficial impact on every element of the economy from average homeowner, to small and large business, and government agency. We have the opportunity now to engage public debate on what form interactive television should take. Should it come about as a series of private, mutually incompatible, insular systems, or should it be like television has traditionally been treated, subject to FCC standards akin to existing NTSC and the recently agreed HDTV standards. This article attempts to provide a framework for a broad discussion of such standards.

    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. (review)

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

    1990-01-01

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

    A TV image of the entire sun while an importance 2N solar flare was in progress was recorded in the extreme ultraviolet (XUV) radiation band 171-630 A and transmitted to ground from an Aerobee-150 rocket on 4 November 1969 using S-band telemetry. The camera tube was a Westinghouse Electric Corporation SEC vidicon, with its fiber optic faceplate coated with an XUV to visible conversion layer of p-quaterphenyl. The XUV passband was produced by three 1000-A thick aluminum filters in series together with the platinized reflecting surface of the off-axis paraboloid that imaged the sun. A number of images were recorded with integration times between 1/30 see and 2 sec. Reconstruction of pictures was enhanced by combining several to reduce the noise.

    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

    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 5years, 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.

    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.

    2007-04-01

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

    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.

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

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

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

    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.

    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.

  7. Multipurpose closed-circuit television teaching cart.

    PubMed

    Folberg, R; Verdick, R E

    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%.

  13. A forecasting study on Chinese television development (1986 to 2001).

    PubMed

    Sun, L

    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.

    1992-02-01

    For 416 college students, questioned about their experiences with aggression and television viewing, only very weak correlations between preference for violent shows and aggression were observed. Black males watched significantly more television than other respondents. These findings suggest that the frequently reported correlation between viewing televised violence and aggression may not appear when sex, ethnicity, and education are controlled in a sample of young adults.

  15. Depth perception and user interface in digital holographic television

    NASA Astrophysics Data System (ADS)

    Barabas, James; Jolly, Sundeep; Smalley, Daniel E.; Bove, V. Michael, Jr.

    2012-03-01

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

    This study evaluated a directly modulated distributed feedback (DFB) laser diode (LD) for cable TV systems with respect to carrier-to-nonlinear distortion of LDs. The second-order distortion-to-carrier ratio is found to be proportional to that of the second-order coefficient-to-first-order coefficient of the DFB laser diode driving current and to the optical modulation index (OMI). Furthermore, the third-order distortion-to-carrier ratio is proportional to that of the third-order coefficient-to-first-order coefficient of the DFB laser diode driving current, and to the OMI2.

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

    PubMed Central

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

    2014-01-01

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

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.

  1. Broadcasting presence: immersive television

    NASA Astrophysics Data System (ADS)

    Harrison, David; Lodge, Nicholas

    2000-06-01

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

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

  19. 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

    Hoffner, Cynthia A.; Levine, Kenneth J.; Sullivan, Quintin E.; Crowell, Dennis; Pedrick, Laura; Berndt, Patricia

    2006-01-01

    Television regularly depicts work-related activities of fictional characters and is one of several important sources of occupational information for young people. However, no research appears to have examined the influence of televised occupational portrayals on economically disadvantaged youths, although television may be an especially important…

  1. Ground-Commanded Television Assembly (GCTA)

    NASA Technical Reports Server (NTRS)

    1972-01-01

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

  3. Effects of television modeling on residential energy conservation.

    PubMed

    Winett, R A; Leckliter, I N; Chinn, D E; Stahl, B; Love, S Q

    1985-01-01

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

  6. 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.

  7. 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.

    1994-10-01

    Three decades of research suggest a causal link between exposure of children to violent images on television and subsequent violent behavior. The epidemic of violence in American society mandates a critical reappraisal of the televised images that children see. To slow the cycle of violence, pediatricians can: (1) Help shape parental attitudes toward children's viewing habits; (2) lobby for school systems to adopt curricula that include critical viewing skills; and (3) work with Congress, Federal regulators, television producers, and broadcasters to reduce the exposure of children to televised violence.

  5. Prevalence of Infant Television Viewing and Maternal Depression Symptoms

    PubMed Central

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

    2014-01-01

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

  4. Overview of FTV (free-viewpoint television)

    NASA Astrophysics Data System (ADS)

    Tanimoto, Masayuki

    2010-07-01

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

While calibration errors are rather greater than those of the Viking Orbiter cameras, both calibration data and processing software applicable to an improvement program have become available through the USGS's Planetary Image Cartography System.

  6. Exciting story of the high-end television projection systems and the novel compact EIDOPHOR AE-12

    NASA Astrophysics Data System (ADS)

    Schulz-Hennig, Joerg F.

    1998-04-01

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

  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

  1. Future trends in compact TV surveillance systems

    SciTech Connect

    Gaertner, K.; Heaysman, B.; Vodrazka, P.

    1985-01-01

    Up to now the IAEA's Safeguards Surveillance Program has been based upon 8 mm film camera systems. As this type of equipment availability is controlled by the needs of the amateur market, the Agency is forced to follow the changing world trend in replacing film with video. The eventual substitution of film with video systems should be influenced by two design approaches, namely integrated systems, resembling physically the present film cameras, and/or remote camera-control unit systems. This paper describes experiments being carried out on both types by some Member States as well as the Agency's activities in this field.

    1997-07-01

    Children's attitudes toward television violence were studied. A 47-item questionnaire collecting attitudinal and personal information was administered to 316 children aged 11 to 16 years. Cluster analysis was used to split the participants into two groups based on their attitudes toward television violence. A stepwise discriminant function analysis was performed to determine which personal characteristics would predict group membership. The only significant predictor of attitudes toward violence on television was the amount of television watched on school days (p < .05), but we also found that the impact of other predictor variables may have been mediated by this factor.
