摘　　要：设计使用独立的网络视频网关将不同协议标准、不同协议栈的网络视频会议终端连接在一起,代替不同视频会议终端携带的不同视频网关,从而克服不能灵活与其他视频终端互通的弊端。此方案只需更换或者开发独立的网络视频网关就可以接入基于不同协议的网络视频会议系统,从而降低网络成本,同时为不同环境下网络互通提供一定参考。In this paper, a separate network video gateway which can connect network video conference terminals in different protocol standards or in different stacks is designed to replace video gateways that are embedded in different video conference terminals. Consequently, this can solve the problem that different protocol standard terminals can＇ t communicate flexibly. The scheme in this paper can adapt to different protocol network video conference systems only by replacing the video gateway or developing this gateway. Therefore, it can reduce the construction cost and provide reference for communication in various network circumstances.
