摘要
基于JMF和多播技术实现了一个没有多点控制单元的分布式视频会议。视音频的压缩由各个客户端来处理,并引入了视频会议的自由模式和主讲模式,两种模式之间的切换由各个对等点之间协调同步完成。在没有多点控制单元的情况下,依然保证视频会议的正常进行。会议中的各个对等点采用多播技术传输视音频流,以尽量减少对带宽的占用。
It is based on JMF and multicast to implement a distributed video meeting with no muhipoint control unit（MCU）. In this system video and audio compression would be managed by clients. And there are two modes of video meeting existing, free mode and speaker mode and the convertion between two modes is done by each peer concurrently and synchronizedly.Without MCU, video meeting would be still normal. To reduce the occupation of bandwidth,each peer in meeting transmits video and audio stream using muhicast technology.
