    The paper describes a study undertaken to assess the data requirements of the three different frame types of MPEG-2; `I' frames, `P' frames and `B' frames. There are many ways that a combination of these three frame types can be configured to make up a group-of-pictures (GOP) and the intention of this paper is to provide a basis upon which different GOP sequences can be compared. For example: in a... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (460 KB)

    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»

    Publication Year: 1996, Page(s):570 - 575
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (472 KB)

    The film and video production industry in California is using 45 Mbps fiber optic telecommunications lines to increase the speed with which it can send work in progress for review, approval and interactive editing. No longer must film or video languish in the back of a car or in the belly of an airplane-it can be sent in real time across town, across the country, and around the world. Compressed v...

    Cited by:  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (584 KB)

    In a complex broadcast environment, there are significant problems in trying to maintain the correct synchronisation of the various programme elements throughout the production chain. Individual delays introduced by equipment soon lead to obvious timing errors between the sound and picture and this problem is exacerbated as the signals pass through different production and distribution areas. The ... View full abstract»

  • Optimising compressed video satellite link budgets for reception at the margins

    Publication Year: 1996, Page(s):471 - 479
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (732 KB)

    Broadcasting to a mobile military audience creates special problems for the service provider. The distribution network is often called upon to service new regions, sometimes at short notice. In order to extend the limits of satellite reception to meet these new requirements a careful evaluation of all the variables involved is necessary. The philosophy adopted in balancing the parameters relating ... View full abstract»

    Publication Year: 1996, Page(s):565 - 569
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (376 KB)

    In various stages of the processes in the broadcast industry and in high-quality contribution, the questions of transparency and room for further processing, are of utmost importance. In this environment, the 4:2:2 video format plays an important role, and the increased need for networking calls for special attention to 4:2:2 compatible video codecs. The data rate of the 4:2:2 format is 270 Mbit/s... View full abstract»

    Cited by:  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (484 KB)

    This paper reviews the changes to test methodology which are required when moving from traditional analogue broadcasting to the new MPEG and DVB digital TV systems. Dynamic multi-programme transport streams, played at data rates of up to about 60 Mbit/s, are needed to perform the role traditionally taken by static analogue test patterns, such as colour bars. Conformance checks for the relevant sta... View full abstract»

    Cited by:  Patents (11)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (624 KB)

    The serial digital data interface (SDDI) is designed to assist studio equipment with the transmission of multiple compressed signals on a single 270 Mbps coaxial SDI cable. Unlike most networking protocols, SDDI offers a synchronous protocol which makes its introduction into the broadcast studio relatively simple. The primary aim of SDDI is to facilitate transmission of compressed video data betwe... View full abstract»

  • A 2/3-inch two-million pixel CCD camera for HDTV

    Publication Year: 1996, Page(s):495 - 500
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (304 KB)

    We have developed a high-performance 2/3-inch two-million pixel CCD camera for HDTV (high definition television). Its sensitivity is as high and it has as good an S/N ratio as existing one-inch HDTV cameras. It is also the compact, light-weight and power-efficient, with operating convenience and mobility equivalent to those of popular cameras used for CDTV (conventional television) systems. In add...

    The search for planning parameters and guidelines to optimize the single frequency networks (SFN) for the new radio media digital audio broadcasting (DAB) has just started. In addition to improving the coverage inside the SFN by considering the minimum wanted field strength and the self interference, the radiated power to the exterior is of great importance. The size of the coverage area is limite... View full abstract»

    Publication Year: 1996, Page(s):560 - 564
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (420 KB)

    Digital television will fundamentally change the way in which we record, store, distribute, receive and consume television. The arrival of satellite television has changed television in terms of choice: from two or three channels, viewers can now have a choice of 50 or so channels. The satellite and cable industries presently plan “multiplex pay-per-view”, also known as “near-vid... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (420 KB)

    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»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (320 KB)

    High definition television systems were first shown at IBC in the early eighties but have since had only limited impact in specialist areas due to the size, weight and consequential cost of high definition processing, storage and transmission. The tremendous development of integrated circuit technology in the 90s together with the maturing of compression algorithms has meant that the above limitat... View full abstract»

  • The introduction of widescreen television in Europe-the digital transition route

    Publication Year: 1996, Page(s):348 - 353
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (496 KB)

    The transition from the traditional 4:3 to the widescreen 16:9 aspect ratio has been making steady progress in Europe. However, for a complete widescreen transition to be accomplished, the 16:9 format must begin to take advantage of the opportunities offered by the development of digital transmission. There are powerful commercial incentives for broadcasters to shift from analogue to digital trans... View full abstract»

    If the visual, audio and computer worlds could be unified under a common digital umbrella, all media would essentially coalesce into a single, comprehensive resource. This is the concept from which DVD evolved. Super-density DVD, with its extraordinary 17 GB capacity, is an ideal medium for providing theatre-quality movies at home. Despite its extremely compact size, the images and sounds are asto... View full abstract»

    Over the last few years, non-linear, computer-based technology has come to dominate offline editing, and there is now no doubt that the same is about to happen to all aspects of online editing and post production. However, knowing that something is bound to happen doesn't mean that you automatically understand when, how and in what order. Many manufacturers and even some users are leaping to concl...
