IP组播视频会议系统的实现及关键技术的研究

The realization of video conference system based on IP multicast and the research of the key technology

提出了一种采用PC机,视频采集设备,以VC++6.0为开发平台及相应的网络技术构建的纯软件视频会议系统设计方案,并利用IP组播技术实现视频会议系统中视音频数据流的通信。同时对本设计方案中出现的用户端控制及QoS问题作了深入研究。

The paper designs the video conference system by using the personal computer,video capturing device, network technology.The system is based on Visual C++6.0 developing platform.The transmission of the video and audio data uses IP multicast technology.Meanwhile,the paper makes the deep research on the control of the user-end and the Quality of Service which arise from the design.
