| Abstract: | In this paper, we introduce the synchronization of media in distributed multimedia system.and concentrate on the video and audio synchronization of distributed multimedia system based on MPEG I and the synchronization of media server and client.In our mechanism, MPEG I stream split up into video stream and audio stream in media server, then video stream are sent to client via UDP to obtain higher transmission rate and lower delay distorrion, whereas audio stream are sent via TCP to avoid data distortion.We realize the synchronization features of MPEG I.In order to reduce UDP Packet Loss, we put forward one rate based feedback mechanism, in which media client answers for generating feedback info, such as Packet Loss rate and receiving rate, and media server controls the transmission rate according to these feedback. |
