Study of Video Conference System Based on RTI and Floor Transmission

With the rapid development of simulation technology and video conference, the research of the video conference in distributed interactive simulation environment is important. The transfer of floor is deeply discussed; the structure of scheduling system and two indicators (Loss Rate and Average of Tardiness) which measure the efficiency of scheduling algorithm are introduced in this paper. An algorithm of the floor transfer is advanced; this algorithm achieved the expected goals in the experiment. Based on the algorithm, the total design of video conference based on RTI is introduced, and the method of video and audio data transmission, which is implemented by HLA interactive class and RTI services, is described in detail.
