视频会议及H.264关键技术在其应用的研究

With the development of computer network technology, the video conference has been greatly improved and wide applications. The structure of the video conference framework, related protocols and their functions in the video conference system are analyzed in this paper, and some problems in video conference are also discussed, such as how to realize the effective video quality, the process of the audio stream, the security of video conference, ect. In particularly, the applications of video codec based on H.264 in video conference system are analyzed, and also we propose some solutions. The experiment shows that the solutions proposed in this paper attain the expected results, possesses a certain practical value and meaning.
