摘要：
A new video coding standard H.264/AVC has been recently standardized. It achieves its high coding efficiency by employing a number of advances in video coding technology. In this paper we propose an efficient rate control method for MPEG-2 to H.264/AVC transcoding. Specifically, the values of quantization parameters for I and B frames are computed adaptively based on the side information from the precoded video. Simulations show that our proposed method can meet the target bitrate accurately and achieves a better performance than the rate control scheme of the reference software H.264/AVC JM 7.4 without increasing the complexity.
