Design And Realization Of USB Player Of Internet TV And Radio Based On P2P

In recent years, with the rapid development of Internet,and based on IP various Internet application emerge in endlessly, living program, vod video and network radio service is also one of them and has become the mainstream of the Internet business. However, the traditional streaming media system is mainly using C/S (client/server) mode, server connects every client by unicast way, and many users joining often cause server bandwidth bottlenecks, P2P technology is a kind solution of solving centralized service with many technical shortcomings (reduce server stress, relieve server load), making full use of network resources, which is widely used day by day. Moreover, currently popular Internet based player most needs to be installed in a computer, not convenient for the user to carry, And playing when plug-in type USB player can greatly user-friendly, ordinary Usb Dongle size, easy to carry, safety, green software, compatible with many Windows operate systems, thus not again confined to a computer.This project main task is to achieve a based on P2P technology esay to plugin-and-play type USB player, can be shown living program, vod video, network radio service and so on.This paper firstly studied P2P technology, compared existing main P2P network structure topology, points out the advantages and disadvantages of different structure topology, and introduces various network structure of representative product realization principle. Then analyzes USB player the status quo and potential market demand, and carried on the detailed analysis and product design, and mainly analyses the USB player of the realization of network video to gain and receiving part, which based on directshow pull mode source filter realization. Then introduces in detail the usb dongle player autorun to play and close technology, and network radio media used by the Windows Media Player introduction and switching technology, etc, and achieve the system. Finally, the paper made a summary of the research content, and puts forward the future direction of the research, etc.
