Multiple Description Coding Based Video Streaming On JXTA Peer-to-Peer Network

A P2P network is a permanent infrastructure which links computers in a small office with copper wires or a P2P network is also network on a much grander scale in which special protocols and applications set up direct relationships among users over the Internet. Video streaming applications have newly attracted a large number of participants in a distribution network. Traditional client-server based video streaming solutions sustain precious bandwidth provision rate on the server. Recently, several P2P streaming systems have been organized to provide On-Demand and live video streaming services on the wireless network at reduced server cost. Peer-to-Peer (P2P) computing is a new pattern to construct disseminated network applications. Typical error control techniques are not very well matched and on the other hand, error prone channels have decreased the handling of video data greatly for video transmission over wireless networks and wired networks based on IP protocol. These two facts united together provide the essential motivation for the development of a new of technique that is capable of dealing with transmission errors in video systems. In this paper, the system has flexible multiple description coding method which improves the frame loss possibilities over independent paths. It introduces concealment technique at the receiver and to conceal the lost frames more effectively. Experimental results show that, the approach attains reasonable quality of video performance over P2P network. The paper work is carried out on the JXTA framework of java platform. The JXTA is used to build the P2P overlay network. The handling of the video data is performed using the JMF and Fobs4JMF libraries of the java language.
