  12. Based on the research of videoconference systems of h. 323 protocol over ip networks and the author ' s experiences of implementing h. 323 videoconference systems in remote education area, in this thesis the main factors that affect videoconference quality are analyzed, and a dynamic bit rate allocation model is proposed and partly implemented. this model is designed to dynamically allocate bit rate for multi - media data flow ( including audio data and video data ) in fixed bandwidth network environment. when continuous multi - media packet losses are detected in ip based h. 323 videoconference system, the bit rate of video data is adjusted meanwhile the bit rate of audio data remains unchanged, and the bit rate allocation of multi - media data ( including audio data and video data ) is optimized as a whole effect
