| Abstract: | With the speed development of Internet and TCP/IP technology .desktop video conference system based on IP multicast technology has been regarded as the hot area of multimedia network application . Video conference system based on IP multicast takes many advantages ,such as less requires on bandwidth, ease of the management of the conference . We have developed an IP multicast video conference system with Microsoft's TAPI 3. 0 , which is a powerful tool for developing H. 323 and IP multicast video conference systems. This paper introduces the architecture of TAPI 3. 0 , specifically the architecture of IP multicast conference. How to realize the multipoint conference is discussed ,also including the deployment of the system on actual network. |
