英文摘要：

With the rapid development of computer technology and Internet, the broadband VOD （video on demand） technology is popular with education and entertainment fields because of its good human-computer interaction and streaming media transmission technology. A VOD system based on DireetShow technology is designed in this paper, in which the VC programming language is adopted. Its communication network is built on the basis of C/S architecture. The communication between muhiclient and server is realized through socket. The test results show that the system can run normally and video playing is fluent. Therefore, it can meet the requirements of network video on demand.
