(A) study on new services under the convergence of broadcasting and telecommunications

Abstract

The rapid development of broadband network and mobile communications technology has made the elimination of border between two different market sectors. This trend is characterized by the convergence of two different market sectors. It includes telecommunication operators and broadcasters who have opened a new market with new opportunities. Based on this background, this study introduced three sections. In the first part of this dissertation, one of the challenges of developing a cost effective distribution system under convergence of broadcasting and telecommunications that supports thousands of new video streams is allocating the video files optimally among various means of media storage. This study develops simple mathematical representations of the cost characteristics of two internet video distribution systems: Content Delivery Network (CDN) and Peer-to-Peer (P2P) networks. This study also identifies conditions under which each or a blend of the two proves most cost-effective. The analysis results show that in many cases a hybrid system is likely to have lower costs than either a pure CDN or a pure P2P network. In the second part of this dissertation, this study decided to analyze the factors that influence users’ adoption of mobile TV in terms of convergence service. This study was to extend the TAM to combine both telecommunication and broadcasting aspects of mobile TV in user behavior. This research also extends the theory of user behavior by incorporating innovation type, gender and age as moderators of user perceptions and individual adoption. Overall, the results revealed that the effect of “ease of use” was very important in attitude toward using mobile TV and both age and innovation type can be key moderators. Finally, this dissertation examines competition between mobile TV services in Korea. This study uses niche theory in which media are modeled as competing scarce resources. The results reveal that the displacement of satellite-based m...
