Abstract :
A novel H.264 frame layer bit allocation scheme based on block histogram difference (BH) is proposed. First, the sufficiency of channel bandwidth is considered at the beginning of each scene. Then, the target bits for each frame are weighted by the relative complexity measurement based on BH. Experimental results show proposed algorithm can adapt to different relationships between channel bandwidth and encoding complexity of video sequence, and achieves better trade-off between channel bandwidth and compressed video quality.
