摘要：
A method to control weighted prediction for video compression. The method comprises (A) generating statistics based upon analysis of a plurality of video frames, (B) detecting a fade condition based upon the statistics, (C) generating one or more estimated weighted prediction parameters based upon the statistics when the fade condition is detected and (D) encoding the plurality of video frames. The encoding takes into account the estimated weighted prediction parameters when generated.
