Tree-mesh structure for real-time streaming media to playback

in recent years, the function of playback for real-time streaming media turns into a hot issue. How to devise the structure and stored approach of video blocks in nodes is the main problem for playback. In this paper we designed a real-time streaming model-TM for live and playback. This model is designed as a combination of the tree and mesh structure. The buffer which is divided into two ranges, fulfill different two sorts of tasks by turns. From the above work, this model can effectively lower the load on the server and the pressure on the nodes, enhance the efficiency of nodes accessing to playback video blocks.
