Research on IPTV Scheduling Algorithms Based on Patching Stream

摘要

This paper describes the development status and key technologies of IPTV, and discusses the advantages of video multicast and the basic theory of multicast. Based on the analysis of the basic idea of stream scheduling strategy and the behavior characteristics of user on demand, the mathematical model of stream scheduling strategy is established, and the performance evaluation parameters of stream scheduling algorithm are proposed. The stream scheduling algorithm of patch stream is elaborated in detail. Two improved stream scheduling algorithms of patching stream are proposed, and their advantages are analyzed through experiments.
