%X Aiming at the shortcoming of H.264 TM5 rate control algorithm on sequence smoothness keeping and buffer controlling, the picture complexity and buffer situation were considered simultaneously, and an improved frame layer rate control algorithm based on H.264 TM5 was proposed. The frames of higher picture complexity were quantized with bigger parameter, while frames of lower picture complexity were quantized with smaller parameter. The buffer situation was also monitored to prevent the buffer from overflowing. The simulation shows that the improved algorithm can not only get smoother picture sequence, but also control the buffer better.
