摘　　要：为增强视频会议临场感,提高视频会议效率,主会场通常需要将图表、数据和文档等计算机图文信息实时传送至分会场。文章对"桌面传送"和H.239双流技术进行对比,指出H.239双流技术已经在高清视频会议系统中逐渐发展成为发送计算机图文的主流技术。分析了高清视频会议系统专线组网带宽分配情况,以华为高清视频终端9039S为参考对象,总结提出了3种计算机图文传送方式,为高清视频会议系统的运维工作提供参考,具有很强的实用性和代表性。In order to strengthen the video conference telepresence, improve the efficiency of video meeting, the main venue usually need to put the graph, data and documentation and computer graphic information to the venue through real-time transmission. For the comparison of desktop transfer and h. 239 double flow technology, this paper points out that the h. 239 double current technology has become the mainstream of the send computer graphic technology in HD video conference system It analyzes the HD video conference system line network bandwidth allocation situation, with Huawei HD video terminal 9039S as the reference object, it puts forward the three kinds of computer graphic mode, provides a reference for operation and maintenance work of HD video conference system, it has very strong practicability and representativeness.
