The Research And Implementation About Streaming Media System Based On P2P Technology

With the rapid development of video streaming, users have more and more demand on high quality of media streaming. Because of the high structuring fees and low quality of streaming video, traditional client-server(C/S) based multimedia streaming system is less adapt to the current operating requirements. A peer-to-peer (P2P) multimedia streaming system is a system in p2p network architecture, utilizing content exchange technologies for delivering and broadcasting digital content through multiple nodes. Different from traditional C/S model, this system is called P2P model streaming media system. The proposed P2P streaming media system can provide high quality and large capacity of streaming services, which is capable of satisfying the present demand of media service operation. This dissertation will describe the research based on the P2P streaming media system.The P2P streaming media system, which is valuable in business, includes three sub systems: user's portable service, P2P streaming distribution, backend operation and management system. P2P streaming delivering system is the key part and it includes the technology of content delivery on P2P streaming intelligent nodes; the technology of digital rights management for streaming media; the P2P streaming media content for streaming and playing. This dissertation pays more attention to the research on these key technologies, and the results and contributions are listed as following:(1) In the technology of content delivery, a method of setting up secondary buffer is brought up to keep the balance of P2P network, to fit media streaming real time delivering for more nodes; Through transferring media streaming by single node, and organizing paths of nodes arithmetic, delivery of P2P streaming media content is realized.(2) Through analyzing security of delivery and rights requirement, establishing feature codes of streaming media, implementing real time holding back and rights examing and controlling delivery, rights of media streaming based on P2P network...
