    The television production video signal chain was once unbroken in having a consistent scanning and interface standard from beginning to end, with few variations in the physical cable interconnection method. Today, the technical and economic advantages afforded by new technologies are irresistible; they are entering the chain but at the same time disrupting it. These technologies include compressio...

    Computers have failed to eliminate video tape from the production chain because of the cost of hard disc storage and the size of digital video files. Now, developments in disc capacity and video compression have made large, hard disc video stores a reality. Some areas of video server technology are still unclear and it is not yet certain that the advantages in production efficiency are real and la... View full abstract»

    The COFDM (coded orthogonal frequency division multiplexing) modulation scheme is effective for digital transmission under multipath fading conditions. A digital 800 MHz FPU (field pick-up unit) that uses COFDM technology has been developed to enable stable live-TV transmission from moving vehicles. In the experimental COFDM-FPU, compressed digital video/audio data are distributed to 572 carriers ... View full abstract»

  • Development of a compact DAB receiver design for the consumer market

    Publication Year: 1996 , Page(s): 267 - 271

    Digital audio broadcasting, DAB, service is now available in the UK and elsewhere, but today's receivers are still bulky and expensive. For DAB to emulate the success of other European digital radio standards such as GSM cellular and achieve its global mass market potential, low cost compact receivers are essential. This goal motivated Ensigma and Roke Manor Research to join forces in 1995 to deve... View full abstract»

    The BBC is considering making the conversion to widescreen as a part of the move to digital television transmission. The digital broadcasts would offer widescreen versions of the BBC's two terrestrial television networks, BBC1 and BBC2, with a large proportion of the programmes made in widescreen. Programmes produced in widescreen would still need to be presented on the PAL analogue transmissions ... View full abstract»

  • The effect of long multipath on digital transmission

    Publication Year: 1996 , Page(s): 68 - 72
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (244 KB)  

    When transmitting compressed digital video and audio over both cable and wireless systems, adaptive equalization is used to compensate for the intersymbol interference caused by multipath in the transmission channel. However, in some cases the echoes encountered in the transmission medium can exceed the length of the adaptive equalizer. This is most likely to occur in MMDS environments which emplo...

    We have introduced “criticality” as a quantitative measure of the difficulty in digitally coding pictures for the purpose of analyzing picture quality statistically. Because picture quality in digital coding depends greatly on picture characteristics such as spatial details and motion, it is not easy to confirm how well a system performs from only a subjective assessment test, in which...

    This paper deals with the return channel (return interaction path) based on coaxial (MATV) and terrestrial transmission. The system described is based on three segments: from the end-user to the MATV head-end through the existing coaxial cable; from the head-end to a return channel management centre, by RF over-the-air transmission; and from this management centre to the service provider, through ...

    The current expansion of broadcast channels is meteoric and continuous. It follows that the need for programming to fill them will also continue to increase, and much of that will continue to come from studio based and studio controlled environments. The associated voice communications systems are as vital as before, only they now are required to be bigger, wider area, easier to use, and increasin... View full abstract»

    Germany is the last large economy that introduced commercial television in recent years. As a result, the choice of station, the choice of method of delivery and last but not least, the choice of employer for those entering the industry have had profound effects upon the economy as a whole. The bulk of the effects of this change have taken hold over a remarkably short period of just five years. We... View full abstract»

    Until a few years ago, “bits” were used instead of “analog signals” in the content production facilities, for the purpose of providing more flexibility and high quality economically, and to create and store information. The prospects widened considerably when employing digital technology to transport signals from the “emission center” to the end user. Once the b... View full abstract»

    The way that video and audio material is edited in post production has changed, from the so-called “traditional” editing methods, to a range of nonlinear computer based workstations. These systems offer fast access to the original data, allowing multiple versions of the same basic material to be created, and the ability to make creative and technical changes at will.
