Design And Implementation Of P2p Technology-based Streaming Media Player

With the computer network's naissance and its technique rapid development, the network stream-media was widely used in our life. There is no need for waiting for and watching a football match for spending a long time, instead of this, the applications of media-storing-order-program and live-online provided by network stream-media are the most wideness. Even, to become perfect. At the same time, the competitiveness among the network companies is so severity to contest the market. Along with the prompt development of rising P2P technique, the using of network stream-media became more and more widely. The 8010 laboratory have been focus on this field since several years ago. So far, we have researched and developed the digital-organism-stream-media system with our intellectual property rights by our ceaseless efforts. The platform of the system is digital organism operation system with high-flexible, high-reliable and high-capacity. Thereinto, the system consists of stream-media-player as client software, media source data collection-store-forward system as middleware and stream-media server. The most important factors of any types of media player are play effect and quality; therefore, there is no exception for P2P stream-media-player. Stream-Media relevant protocol stack, relevant technique, synchronization among data streams and design of network are the vital factors. So, the dissertation of this article will cover these points.The general content are shown as follows:Introduce stream-media basic conception, major technique, development process, relevant protocol; P2P principium and application; the code format such as H.264 and MPEG, etc.Researching and analysis the stream-media protocols'application and realization within stream-media and sub-system. Fully describe the mostly function interface, function parameters, data structure and message parsing for each protocol such as RTP/RTCP,SDP,RTSP.Introduce the definition and realization of the interface among the stream-media player and its sub-system. Expatiate the design of architecture of stream-media-player. Introduce the popular stream-media synchronization arithmetic, and make the simple comparison; expatiate the significant meaning of synchronization, introduce the one of synchronization mechanism realization in detail. The media-player is base on the digital organism operation system, therefore, it have several special characters besides normal feature, such as Resume broken transfer.
