However, problems of complexity and burden of network structure, packet loss, packet damage, and packet delay are rising with the growing video and audio traffics, and furthermore will destroy the basic function as a result of bursting network traffic. In order to solve the problem described before, we adopt a control mechanism for network video and audio data transmission and it was be implemented on embedded platform with H.263 Video Codec and G.723.1 Audio Codec. We expect this mechanism can work efficiently on controlling the video and audio transmission data size via the initial bandwidth estimation and dynamic throughput adjustment. After a series of verification, the result comes to a conclusion of the embedded video phone system with rate control can work correctly in any kind of network environment and performs the video quality smoothly.
