%X During the video communication process, an improved rate control algorithm was developed based on H.264 video coding standard in order to make the output data stream better adapted to different channels. Contrary to the MAD prediction of the basic unit only considering the relationship of the time in the coding standard, a new prediction method was introduced combining time prediction and space prediction. Compared with coding standard, the experimental results illustrate that the new algorithm can control rate more precisely and increase the peak signal noise ratio of the output video stream effectively. It proves that the new algorithm can make the output data stream of the encoder more stable.
