Trends of Media Productions Commercialization and Factors of Information Allotment in developing Countries

The public service media (PSM) theory differs from the commercial theory by its inclusiveness of ‘public interest’ in addition to media sustainability for both public and private media. In public goods theory, the nature of media economics is far reaching. Thus, the aim of this study is to investigate factors that determine healthy media development of Ethiopia on account of its fast economic growth. About 10 media houses were purposively selected. The selection merits of media study for content analysis relay on media categorical share (print, broadcast), circulation and area coverage. The study applies primary and secondary data collection. Descriptive statistics and multiple regressions are taken as an analytical tool. The study finds out that news has scale effect on public service media at every unit analysis of media strata. As air time/column space changes by unit measurement, news package information delivery for poverty alleviation had an increase changing pattern. Moreover, the tendency of media capital formation (private, public) development of media in the country shows strong positive relation with the public service media value. Finally, public media exposure which stands at 30% is below the minimum requirement compared to speed of radio coverage which stands at 85% for the country in the study year. The promising news information delivery in poverty alleviation should be kept by reinforcing editorial policy and strictly implementing the law that prohibits advertisement on news package. Promotion of circulation and program rating, standardization and modernization of program differentiation are vital to improve Advertisements/Sponsorship expediency and enhancing variety of programs/ editorials for poverty alleviation respectively

Building Internet caching systems for streaming media delivery

The proxy has been widely and successfully used to cache the static Web objects fetched by a client so that the subsequent clients requesting the same Web objects can be served directly from the proxy instead of other sources faraway, thus reducing the server\u27s load, the network traffic and the client response time. However, with the dramatic increase of streaming media objects emerging on the Internet, the existing proxy cannot efficiently deliver them due to their large sizes and client real time requirements.;In this dissertation, we design, implement, and evaluate cost-effective and high performance proxy-based Internet caching systems for streaming media delivery. Addressing the conflicting performance objectives for streaming media delivery, we first propose an efficient segment-based streaming media proxy system model. This model has guided us to design a practical streaming proxy, called Hyper-Proxy, aiming at delivering the streaming media data to clients with minimum playback jitter and a small startup latency, while achieving high caching performance. Second, we have implemented Hyper-Proxy by leveraging the existing Internet infrastructure. Hyper-Proxy enables the streaming service on the common Web servers. The evaluation of Hyper-Proxy on the global Internet environment and the local network environment shows it can provide satisfying streaming performance to clients while maintaining a good cache performance. Finally, to further improve the streaming delivery efficiency, we propose a group of the Shared Running Buffers (SRB) based proxy caching techniques to effectively utilize proxy\u27s memory. SRB algorithms can significantly reduce the media server/proxy\u27s load and network traffic and relieve the bottlenecks of the disk bandwidth and the network bandwidth.;The contributions of this dissertation are threefold: (1) we have studied several critical performance trade-offs and provided insights into Internet media content caching and delivery. Our understanding further leads us to establish an effective streaming system optimization model; (2) we have designed and evaluated several efficient algorithms to support Internet streaming content delivery, including segment caching, segment prefetching, and memory locality exploitation for streaming; (3) having addressed several system challenges, we have successfully implemented a real streaming proxy system and deployed it in a large industrial enterprise

On Transmission System Design for Wireless Broadcasting

This thesis considers aspects related to the design and standardisation of transmission systems for wireless broadcasting, comprising terrestrial and mobile reception. The purpose is to identify which factors influence the technical decisions and what issues could be better considered in the design process in order to assess different use cases, service scenarios and end-user quality. Further, the necessity of cross-layer optimisation for efficient data transmission is emphasised and means to take this into consideration are suggested. The work is mainly related terrestrial and mobile digital video broadcasting systems but many of the findings can be generalised also to other transmission systems and design processes. The work has led to three main conclusions. First, it is discovered that there are no sufficiently accurate error criteria for measuring the subjective perceived audiovisual quality that could be utilised in transmission system design. Means for designing new error criteria for mobile TV (television) services are suggested and similar work related to other services is recommended. Second, it is suggested that in addition to commercial requirements there should be technical requirements setting the frame work for the design process of a new transmission system. The technical requirements should include the assessed reception conditions, technical quality of service and service functionalities. Reception conditions comprise radio channel models, receiver types and antenna types. Technical quality of service consists of bandwidth, timeliness and reliability. Of these, the thesis focuses on radio channel models and errorcriteria (reliability) as two of the most important design challenges and provides means to optimise transmission parameters based on these. Third, the thesis argues that the most favourable development for wireless broadcasting would be a single system suitable for all scenarios of wireless broadcasting. It is claimed that there are no major technical obstacles to achieve this and that the recently published second generation digital terrestrial television broadcasting system provides a good basis. The challenges and opportunities of a universal wireless broadcasting system are discussed mainly from technical but briefly also from commercial and regulatory aspectSiirretty Doriast

Instructional television utilization in the United States

Various aspects of utilizing instructional television (ITV) are summarized and evaluated and basic guidelines for future utilization of television as an instructional medium in education are considered. The role of technology in education, capabilities and limitations of television as an instructional media system and the state of ITV research efforts are discussed. Examples of various ongoing ITV programs are given and summarized. The problems involved in the three stages of the ITV process (production, distribution, and classroom utilization) are presented. A summary analysis outlines probable trends in future utilization

Dynamics of a Periphery TV Industry: Birth and Evolution of Korean Reality Show Formats

Television format, a tradable program package, has allowed Korean television the new opportunity to be recognized globally. The booming transnational production of Korean reality formats have transformed the production culture, aesthetics and structure of the local television. This study, using a historical and practical approach to the evolution of the Korean reality formats, examines the dynamic relations between producer, industry and text in the context of cultural globalization and suggests a new perspective of television studies challenging the center-periphery model
