Applications Of Multiple Screen Interactive In High-definition TV Platform

With the pace of convergence in China continues to advance, the cable TV network,wired communication networks, broadband Internet in the process of integration of unifieddirection of evolving, technology, services and features tend to be consistent, the scope ofbusiness tends to be the same, network interconnection, sharing of resources, to providecomprehensive services for users (including but not limited to voice, data and broadcasttelevision and other services). Domestic radio and television industry and telecom operatorshave to deploy their convergence work, but because of policy and the distribution of benefitsthe country given the uncertain, multi screen interactive business now mainly rely onintelligent television terminal manufacturer, intelligent Internet video terminal manufacturersand telecom operators to promote. The radio and television industry will encounter manyproblems in the early development of multi screen interactive service. In order to solve theseproblems, broadcasters must do various business and technical reserve in advance.In this paper, I am radio and television industry in the background of networkconvergence, build a high-definition TV platform, multi screen interactive applications withradio and TV characteristics, especially the discussion and Research on the technology systemof multi screen interaction and the practical development and application.This paper first introduces the domestic each big operators or other fields of enterprisesin the development of multi screen interactive applications, with the domestic broadcastingindustry platform HD TV as an example, introduces the construction background of HD TVplatform integration, including its main Portal portal system, BO system (business operationsupport system), a few big plug flow system and CDN system. Then through the introductionof technology system of multi screen interactive system and the realization of the program,such as video broadcasting, time shift back to see, video on demand, the remote control, leftscreen and other categories of business functions to elaborate the multi screen interactivebusiness in HD TV platform is how to achieve; through the research and analysis of thedetailed process of Guangdong Radio and television network multi screen interactiveapplications, technical architecture, discusses the relationship of multi screen interactivesupport system core functions and application of the surrounding system.
