The Research And Realizes Of Emergency Command Video Conference System

Being the most popular multimedia conference system technique, it has already got in the top of the common and public project more extensive applied. The multimedia conference system equipments is expensive, the function is single and apply of the network environment request to engrave, usually appearing a lot of units to purchase hereafter the opportunity to apply is not much, the equipments is an idle condition aver along period of time. Result in system of the application is limited by common and public item only, can hardly adapt large item perhaps special kind profession item.On the base of researching the key technology of video conference (picture compress technology, audio compress technology, IP multicast technology), the paper brings up that a Hi-resolution video conference system of emergecy command can meet the best use of net. Uniform management, easy expand features in the special net and the system realizes connection with former H.32X system. Furthermore, the paper research the system structure, the way of making up the net, control mode, switch mechanism of NCU frame.Finally, The causes of these problems are analyzed.
