Research On The Key Technology Of Video Living System Based On P2P Network

With the popularization of Internet networks day by day, and the rapid development of information transmission technology, p2p network technology has obtained the great progress. At the same time, p2p video on demand, Video Living System, the distance education, security monitoring have obtained massive applications, the success utilization of p2p technology in such system have received many attention from domestic and foreign scholar's.In recent years, streaming media technology is the emerging multimedia technology, media Streaming file coded by the front server, it allow downloaded and played the multimedia data through the internet at the same time, users do not need to wait for the time when the file downloading finished. At present, streaming media technology and p2p technology have combined, and apply in the Video Living System.This paper take the application of P2P networks in video living system for study, through the research, we have completed the following work:1. Author deeply understand the P2P network's developing process, and the basic structure principle, which included the characteristic and the application domain of P2P; I deeply study the streaming media technology, which included the basis of streaming media technology and transport protocols.2. The overall framework of the video living system has been designed in this paper, author elaborated the function and structure of each module in detail, and which included front living module streaming media server, the client broadcast system. 3. This paper study several issues about the system, this paper designed an effective incentive mechanism to encourage users to upload resources according to the selfish of most users. This incentive mechanism take the resource management system based on auction,this way can makes the system user nodes willing to contribute resources, so,it can achieve the goal of raises the efficiency.The main purpose of this paper is to realize Video Living Video Living, we can realize that the sound, the video multimedia information may transport through the P2P network high quality, small delay, as long as in the wired network environment, and also assure the synchronous of the picture and the sound. This kind Video Living System can realize the transmission of multimedia information high quality, this system have wide applications according to the many features, for example, real-time,high reliability, small delay, the system have cost-effective commercial value, and also the huge economic prospect and the social benefits.
