Abstract: With the development of streaming media technology and cloud computing, and the emerging on more and more streaming application platform, transmission and sharing on steaming information have been facilitated. But there exist a lot of problems, for example, playing state handover and broken-point continuingly-playing, and so on. A streaming media application system based on live mesh of cloud computing was proposed in this paper. The system adopted URI and XML to accomplish media source centralize management, and used LAN UDP broadcast and multi thread mechanism to realize real-time handover on steaming media playing state between terminals. At the same time, the broken-point continuingly-playing was carried out with message management mechanism based on Live Mesh. The experiments show that the sharing on the same streaming media resource and the seamless handover on playing state have been well implemented between terminals, and the broken-point continuingly-playing has also been intelligently achieved.
