The Key Technology Of The Embedded Iptv Streaming Media Player

With the rapid development of Internet technology, streaming media technology and the embedded technology, the IP-based interactive TV which used streaming media technology will be applied more extensively. IPTV take technology advantages of traditional and modern interactive digital television provide users with live television, timeshift television, the video-on-demand, web browsing, games and other interactive television business in internet. Greatly enrich people's family life, and have broad market prospects and value.The subject base on Guangdong Telecom's IPTV project, we design and implement a IPTV Embedded Streaming Media Player. As the ultimate expression of who operations in the terminal equipment - STB, this player compatble ISMA and MPEG-TS digital media transmission standards; support MPEG4/H264 video decoder, support MP2/MP3/AAC audio decoder; design a hierarchical structure, with a high degree of scalability, based on the standard C language, meet the POSIX standard, with good portability and platform independence.Firstly, papers intrduced IPTV technology and the development of streaming media technology. Then analysised the main and the leading technology of audio and video coding standards, as well as streaming media description of the transmission, control related protocl; Sencondly, in view of the subsequent rapid channel switching, buffer management of the IPTV Streaming Media Player, lip synchronization of audio and video, and an analysis of key technologies, on the basis of a detailed exposition of IPTV Streaming Media Player embedded in the design and implementation; The strong expansion of a multi-process architecture Streaming Media Player. Analyze and formulate the end streaming media player and content distribution network interface. Implement all of the IPTV streaming media business.
