| Abstract: | A distributed and loosely coupled multimedia conference system is designed and implemented in this paper.The system uses a special digital-analog hybrid networking technique.And it uses IP multicasting to transfer the video,audio,and monitoring streams.An agent mechanism is incorporated in this system to implement the distributed peer-peer architecture.According to the engineering experience and the users' feedback,the scalability and maintenance of the de-sign are easier to be achieved than that of the conventional H.323multimedia conference system. |
