Abstract
The standard rate control algorithm works with all the levels such as the GOP, frame, and unit levels. However, it cannot allocate bits reasonably under the condition of scene change. In this paper, an efficient rate control algorithm to detect scene change and reallocate the channel target bits of H.264 is proposed. The proposed method can detect scene change effectively and change the length of GOP adaptively, so the target bits can be allocated more reasonably than standard rate control algorithm.
