摘要：
This paper presents a novel rate control initialization algorithm for H.264. Firstly the first instantaneous decoding refresh frame in a video sequence is intra-coded to get the mean absolute difference (MAD) value, then the average MAD value of the second, third and fourth frames which are inter-coded is computed, finally the initial quantization parameter is determined depending on the bits per pixel and the two MAD values. When compared with the algorithm JVT-G012 [4] which is the current recommended algorithm implemented in the H.264 reference software JM13.0 and the algorithm [5], the proposed algorithm can increase the average peak signal-to-noise ratio of reconstructed video by tip to 1.241 dB and 1.262 dB, respectively(1).
