The Design And Realization Of MPEG-4 VOD System Based On Campus Network

Abstract The Video-On-Demand(VOD) system is a network system including hardwareand software．The VOD software transmits multi－path,concurrent video data－stream real time from video server to client．It may offer interoperability to user insome degree． The VOD is rapidly developing with computer technology(especiallydigital compression and decompression of multimedia),network communicationtechnology. VOD (Video on Demand) system can be widely used in many fields, such aslong distance education, digital library, news on demand, TV on demand and etc. This paper focuses on the design of setting up a Video-On-Demand systembased on campus network by means of streaming media technology and MPEG-4encoding technology. Then it compares and analyses the key technologies used in setting up aVideo-On-Demand system. Finally, it elaborates on the realization of management informationsystem for Video-On-Demand system.
