| Abstract: | 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. |
