Abstract

With the development of information technology, the application of network TV service has been developed rapidly. Reducing the channel switching time is the key factor to improve the quality of service, and is also one of the problems to be solved in the large-scale application of IPTV service, on the basis of summarizing the main channel switching schemes at present, an improved fast channel switching scheme is proposed in this paper. A temporary channel is used to speed up the transmission of streaming media in the process of media transmission, and a double buffer is used to store the media data in the transmission terminal to realize the fast switching between different channels.
