中文摘要	The paper presents a scalable, extensible and cost-effective VOD(video-on-demand) integrated system for delivering MPEG-4 streams to PCs or consumer terminals over IP networks. The proposed system includes three parts: the cluster middleware, the VOD servers and the transcoding servers for carrying out the real-time transcoding of MPEG-2 video to MPEG-4 video. The cluster middleware makes the VOD servers easily scalable to resolve a basic performance bottleneck, which has been encountered in the design steps of many other VOD servers. By distributing CPU-exhausted computation to the transcoding servers, the VOD servers can seamlessly integrate some services such as DVB streaming over IP and live broadcasting. Our proposed architecture is believed to provide several strategies for the practical implementation of the VOD system, and the whole system is implemented and tested extensively over university LAN networks.
