The Research And Application Of Media Streaming Based On BT Protocol In The Embedded System

In recent years, the application of Internet streaming media has been developing rapidly, but the transmission speed of streaming media is not good. The traditional client/server model very easily leads to the performance bottlenecks of server and the waste of resources, which can not effectively support large-scale data distribution of streaming media. In addition, IP multicast technology can't be disposed easily because of the reasons, such as the complexity of protocol, the heterogeneity of network, and lacking the reliability of multicast. Under P2P model the client network is used as center of date distribution,instead of the streaming media server, so it can effectively resolve the server-side bottlenecks.Meanwhile, with the development of the network technology and microelectronics technology, the embedded devices with a streaming media are porpular to people. The present paper focuses on the researching of streaming media technology applied into the embedded devices, to provide clearer, smoother playback and real-time transmission. The specific contents of the paper are as follows:1.Researching the P2P network and streaming media technology deeply, setting up multicast technology of the P2P network application layer, the network topology design and the development of streaming media and related technology.2.Studying BT protocol widely used download software, and proposing a streaming media system based on BT P2P protocol. The system incorporates traditional P2P networks and C/S technical advantages, which can support a large number of users to receive real-time streaming data. In additional, the self-organizing capacity can effectively reduce the pressure on the server and avoid network congestion from occurring.3. Analyzing the characteristics of embedded systems, and proposing a client system model with P2P streaming media. On the basis of this design, we design the torrent client of embedded streaming media and server-side software. With the existing tracker server software, we ultimately integrate them into a complete P2P streaming media system.
