Abstract

In the video and audio chatting system, the transmission control of media stream is one of the most important issues. This paper introduces system solutions and design of key technologies, including the DirectShow framework of real-time audio and video exchanging, combined with MPEG-4 audio and video coding technology. We streamline the RTP protocol to achieve a good audio and video data analysis and packaging strategy, and we also use RTCP protocol to provide relevant information which can be used to adjust the sending rate of network so that the system will meet the user to the quality of communication.
