Abstract:

This thesis is concerned with the FM demodulator techniques used in terrestrial TV receiver designs for Direct Broadcast Systems (DBS) from satellites. The various MAC/Packet schemes intended for DBS applications are described and the international standards that apply to them considered, with particular emphasis on the D2-MAC system. Noise in FM systems is discussed and a suitable threshold noise model is chosen for use in DBS TV demodulator systems. The characteristics of the various types of noise effects are considered in terms of their effect upon the TV picture. The threshold performance of a conventional FM demodulator for differing types of modulation is reviewed and it is shown how the threshold characteristic depends upon the nature of the modulation. The literature review carried out represents a significant component of the thesis and combines material from patent literature with more conventional source materials from professional journals, conferences, textbooks, etc. Some ten existing demodulator concepts that exhibit threshold extension characteristics are examined, and where relevant their potential performance in D2-MAC format systems is assessed. The demodulator characteristics that limit their performance in TV systems are identified. It is concluded that designing a threshold extension demodulator, with reliable operation, for all picture contents and for a wide range of input carrier-to-noise ratios, is a formidable task using existing design techniques. On the basis of this examination an adaptive threshold extension demodulator concept is proposed, that utilises information contained within the signal structure to achieve an improved performance over a wide range of input carrier-to-noise ratios and picture content. It is shown how the relevant signal structures may be derived from conventional (PAL, SECAM and NTSC), MAC format and all-digital television systems. Illustrations are given that show how the adaptive demodulator concept can be applied to certain existing threshold extension demodulators, enhancing their performance for television picture reception. Future trends in all-digital DBS TV systems intended ultimately for DBS applications are briefly discussed together with their demodlilation requirements.

Abstract:

An important problem for economists and policy-makers concerning the cable industry is whether the cable industry faces widespread direct competition. Only one roughly comparable, nation-wide competitor exists, Direct Broadcast Satellite ("DBS"), and there are some indications that DBS does not constrain cable prices. The model presented in this paper indicates that DBS and cable compete imperfectly in terms of monthly prices, if at all, but compete more directly in terms of the premium-level services they offer. Other factors may indicate whether a community is open to advanced services like DBS, such as whether the cable operators offers high-speed Internet access.

Abstract:

This thesis focuses on the development of the Direct Broadcasting Satellite in Japan under its Kodo Johoka Shakai (Highly Advanced Information Society) policy. The field of new media policies is relatively new but very important in communications studies. The development of new media technologies changes into existing media systems, and profoundly influences economies which are increasingly dependent upon information services.
Japan's case is particularly interesting. Relatively little is known about its DBS policy compared to other industrialized countries, even though Japan has already begun to operate DBS under its own version of the "information society", the Kodo Johoka Shakai (Highly Advanced Information Society). The formulation of DBS policy is related to many factors, including space development, research and development, broadcasting, international telecommunications regulations and economic competition both in international and domestic markets. In order to take these factors into consideration, an historical approach and institutional analysis are used in this thesis.

Abstract:

Within the context of debates surrounding the consumption of global media by local audiences in Third World countries, this study explores the reasons behind satellite television subscription, and consumption of international news among a sample of young professional men and women in contemporary Zimbabwe. The study seeks to uncover how the research participants respond to news broadcast on SABC Africa's '60 minutes live in Africa', a programme which they can only access via satellite television in their country. Working within the frame of audience studies which insists on understanding media consumption and reception in context, this study examines how the respondents, situated within the specific Zimbabwe context, characterised as it is by serious social, economic and political challenges, respond to both regional news and news about their country on '60 minutes live in Africa'. Within the frame of qualitative research the study employs a two-stage sampling procedure and data collection strategy to uncover the factors that underpin international media consumption and reception by professional men and women situated in a country undergoing rapid change. The findings of the study point to the various social and individual factors that underlie media consumption choices as well as to the different socially patterned reasons why local audiences are either attracted to, or reject global media. The study found that SABC Africa's '60 minutes live in Africa' is more popular and better received than Western-broadcast programmes on channels such as BBC, CNN, and Sky News among Zimbabwean professionals. I also uncovered some evidence that cultural proximity and relevance are of supreme importance in determining which media audiences chose to consume and what level of engagement they bring to their reception of global media. These and other findings directly confront media models that privilege beliefs in cultural imperialism and the dominance of Western media and their effects on Third World audiences.

Abstract:

The growth of direct broadcast satellite television distribution to the home as a viable competitor to cable and terrestrial broadcast has fostered the availability of special interest or niche channels and therefore provided greater choice to the viewer. This study, based on uses and gratifications theory, examined the relationships among ritual and instrumental viewing motivations and satisfactions, viewer religiosity, and viewing attentiveness as they related to the selection of a niche television channel, Brigham Young University Television. The uses and gratification approach provides an appropriate framework for studying "media consumption, the interrelated nature of television user motives, and the relationships among viewing motives and viewing patterns" (Abelman, 1989, p. 57). Data was gathered by way of an online survey of non-random, self-selected BYU Television viewers. Participants answered 67 questions about their motives for choosing to view BYU Television and the gratifications they received from their viewing. The 596 valid responses to the survey were analyzed. The study results are in harmony with previous uses and gratifications studies examining ritual and instrumental viewing patterns. The data found positive relationships between instrumental viewing motives and instrumental viewing satisfactions, as well as instrumental viewing motives and viewing selectivity. There was no support for those hypotheses that dealt with the level of viewing attention as it related to religiosity or instrumental viewing motives. Future topics of study are suggested including the opportunity an expanded media universe provides to increase the depth and breadth of uses and gratification theory, as well as to study the role of niche television services in community building.

Abstract:

Le phénomène des télévisions satellitaires a fait son apparition dans le monde arabe en 1990-1991. Date de l’instauration du Nouvel Ordre Mondial. Une progression foisonnante s’est produite, par la suite, profitant d’un espace géolinguistique étendu, d’une ouverture sans précédent et d’un financement généreux. Sont-elles l’expression d’un changement ou bien celle d’une adaptation ? Et au service de qui ? L’étude des chaines d’information en continu Al Jazeera, Al Arabiya ou « flexibles », Abou Dhabi et Al Manar est particulièrement intéressante pour répondre à cette question. Comprendre le fond de ce phénomène, les intérêts qu’il représente, qu’il sert, et les limites du changement qu’il est capable de produire, exige de dresser un état des lieux panoramique, une étude de la géopolitique qui a donné lieu à la naissance de ces télévisions, et qui a dicté les évolutions qu’elles ont subit. L’analyse du contenu et du discours vient repérer les expressions d’une culture démocratique, ou anti démocratique, dont dépend la nature du changement
Since 1990-1991, the number of satellite channels and viewers has grown exponentially in the Arab world, taking advantage of a geolinguistic space that afforded unprecedented degree of openness in a field previously dominated by t ightly-controlled state-owned television stations. The date also coincides with the inception of the New World Order, the waging of the first Gulf War which established a new regional order, and the stirrings of the society of communication. This study of news channels (Al Jazeera, Al Arabiya) and “flexible” channels such as (Abu Dhabi and Al Manar), aims to examine whether they are an expression of change or adaption and whether they serve to perpetuate the status quo of the powers that fund them

Abstract:

Abstract One form of broadcasting that threatens to overcome national boundaries is high-powered direct broadcast satellites (DBS). DBS as a concept goes back to 1977, when a World Administrative Radio Conference (WARC), in a contentious meeting pitting the United States against the rest of the world, established the basic framework (Pool, 1991). At the time, European officials saw DBS as imminent. They regarded it as a wide-open field where no country had yet achieved technological dominance and where the potential existed to develop domestic electronic strength. It was also viewed as a way to establish the traditional national broadcast institutions in space, since DBS’s large power requirements permitted only a small number of channels, thus causing little disruption to the existing national systems. To achieve high-power beam required a small “footprint” of coverage; thus, the scarcity of channels in the sky would match the scarcity of channels on the ground.

Abstract:

Abstract The advent of Direct Broadcast Satellites requires the associated development of origination facilities supporting hundreds of viewer channels. Such facilities use highly automated, fault tolerant control systems to facilitate cost-effective staffing levels and the flexibility to support services that are only now evolving. We summarize the capabilities and architecture of two such facilities that are among the largest in the world: the more than 175 channel DIRECTV® Castle Rock Broadcast Center (CRBC) servicing the continental United States from Colorado, and the 72 channel DIRECTV International Inc. California Broadcast Center in Long Beach servicing Latin America and the Caribbean. For program transmission, these services use the latest, high-powered Hughes Kuband communication satellites. For program playback, each plant uses relatively conventional digital tape-based technology. Two factors make the program playout operations unique. First, their extreme size and scope. Second, all the resources in the plant are sharable and schedulable among different viewer channels to assure the plant can adapt to the services demanded by their evolving market. Some “lessons learned” are then discussed as suggestions to aid future product and facility developments.
