Abstract
Since the current rate control schemes in H.264 do not present the capability of efficient frame-level bit allocation, the video quality varies greatly for sequences with scene cuts or large motions. To overcome that limitation, we propose a rate control scheme based on the incremental proportional-integral-differential (PID) algorithm. That algorithm is introduced to control the buffer and decrease the influence of buffer surface fluctuation on the process of frame-level bit allocation. Extensive simulation results show that this rate control scheme, without expensive computational complexity added, decreases the average video quality variations by 21.07%.
