    In the next decade, digital techniques will be applied comprehensively in broadcast television studios. Until recently, digital technology has had its greatest impact in applications involving control and maintenance aspects of studio and network design. The video signal path has not yet been subject to digital operation, although considerable research has been reported and much discussion has tak... View full abstract»

  • Development of video cameras and recorders for lightweight television production

    Publication Year: 1982, Page(s):436 - 444
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1408 KB)

    The early development of broadcast television equipment for professional use was constrained by the need for the best possible technical performance for a market that was limited in its extent. Thus video cameras and recorders were expensive, technically complex, bulky and had high power consumption. During this period the use of such equipment was almost exclusively restricted to broadcasters. Gr... View full abstract»

    Over the last few years there have been dramatic changes in the design of telecine. These have been made possible by advances in semiconductor technology. The paper discusses the problems of transferring film to television, and describes the earlier type of flying spot telecine. The potential impairments, particularly in terms of shading and focus interlace flicker effects are discussed. The first... View full abstract»

  • Transportable satellite up-links towards SNG?

    Publication Year: 1982, Page(s):473 - 477
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (808 KB)

    The possibility that satellites could be used for occasional outside-broadcast (OB) links has interested broadcasters for many years. It is only within about the last five years that practical experiments have been possible, but it is clear that highly mobile satellite news gathering (SNG) links are now becoming available. Most of the early satellites used the 6 and 4 GHz frequency bands on relati... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1073 KB)

    A review is given of the various aspects of broadcasting television programmes directly to the public from a geostationary satellite. To implement the basic system requires consideration of the characteristics and control of the satellite, the receiver technology and the link which carries the programmes to the satellite. For Europe, economic considerations suggest that using a power permitting go... View full abstract»

    After giving details of the World Adminstrative Radio Conference plans for satellite broadcasting, the implications of direct broadcasting from satellites in the UK and the rest of Europe are discussed. The technical parameters of the composite television signals in use at present are considered in relation to their transmission via frequency-modulated satellite channels at 12GHz, and a completely...

    The paper describes some recent technical trends in the design of television receivers. It reviews the factors that influence the specification of a modern television chassis, and identifies the main features which are incorporated into it to suport an appropriate product range. The paper deals in detail with the latest circuit and scanning techniques, and a Section is devoted to new electronic se... View full abstract»

  • Unattended television and radio transmitters in the UK

    Publication Year: 1982, Page(s):507 - 514
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1501 KB)

    The paper states that the dramatic growth in the number of UK broadcast transmitters during the last three decades has been made practicable by the almost universal adoption of unattended operation techniques. It discusses the philosophy of unattended operation and then considers the requirements for the transmitters, RF feeders, power supplies and programme inputs necessary to implement such a ph...

    It is reasonable to assume that everybody who listens to the radio or watches the television does so subjectively; it would be delightful if all assessments of the performances of broadcasting equipment could be made entirely in that way. Regrettably, this is not possible owing to human inconsistencies, and so the broadcasting engineer resorts to objective testing. The paper covers some details of... View full abstract»

  • Multiple sound channels in satellite broadcasting

    Publication Year: 1982, Page(s):528 - 531
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (503 KB)

    Since the agreement in 1977 of the plans for satellite broadcasting, there has been a growing interest among broadcasters for improved sound services to accompany the television picture by satellite. The original plans were for one analogue sound channel, but requirements now exist for stereophonic sound, multilanguage sound and also high-quality sound services not associated with the television p...

    In recent years the requirement for the introduction of a two-way speech facility for the public at large has gradually increased. This facility has become well known as citizens-band radio (CB), and is used extensively in the USA and most Western European countries. Equipments operate using frequency modulation, amplitude modulation, single sideband and generally utilise the frequency band 26.960... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (611 KB)

    The UK teletext system, based on a rugged fixed-format concept has proved itself to be an inexpensive and effective means of data broadcasting. In spite of this, there has been recent pressure to make available a greater degree of sophistication, in order to provide facilities at least equivalent to those of subsequently proposed alternative teletext systems. The response has been to develop a ran... View full abstract»
