Conventional TV viewing via cable is evolving to Satellite, IPTV and P2PTV based systems. Commercial peer-to-peer systems like Zattoo, Joost are some reputed systems for P2P live streaming. When most content is live or not, file transfer is better in broadcast based systems such as youtube. But as the volume of interesting content soars, Internet scale search and delivery beats any local services which are the driving force behind P2P Streaming Services. Peer-to-peer (P2P) streaming has been widely deployed over the Internet. A streaming system usually has multiple channels, and peers may form multiple groups for content distribution. In this paper, we propose a distributed overlay framework (called SMesh) for dynamic groups where users may frequently hop from one group to another while the total pool of users remain stable. SMesh first builds a relatively stable mesh consisting of all hosts for control messaging using the Delaunay Triangulation (DT) protocol. The mesh supports dynamic host joining and leaving, and will guide the construction of delivery trees. Here, we propose to use a new mechanism based on supervision Game, and formulate a mixed Nash equilibrium strategy adopting the supervision game. A balanced supervision cost and peer participation income model is analyzed and implemented along with a limited number of repeater nodes. _________________________________________________________________________________________
