Design And Implement Of Video Broadcast System Based On JXTA

Along with the development of Internet and communications technology, especially the improvement of the Internet bandwidth, the codec technologies for video and audio, together with the standardization of streaming-related protocols have facilitated this trend, it more possible for the transmission of high-quality and real-time streaming media, based on streaming media transmission systems are becoming more and more popular. New communications technologies for delivering the latest information and knowledge of teaching provided more channels for the network media streaming resources, Construction has brought a breakthrough. However, based on the traditional C/S or B/S structure of media streaming system, there are also such as the high cost of construction, the server of network bandwidth requirements, users too many players at the poor quality shortcomings. P2P technology applied in the media streaming system to solve the network resource sharing between users and live interaction, the server bottleneck problems, the solution of knowledge acquisition, dynamic learning freedom becomes possible.With regards to NEMIS, the papers analyzes and research the characteristics of the current multimedia network, based on a peer to peer network, a new distributed resources, and share the height of open and free development of JXTA platform based on streaming media system.This paper expounds on the definition of the new technology, the agreement system and the application of objective, and then introduces the JMF, a multimedia technology in java. Paper based on P2P streaming media system design of the system, such as a functional analysis; overall structure of the system and a key module design based on JXTA streaming media system to achieve the specific process was discussed.
