提出了一种基于H.264/AVC的空域分级视频编码器方案,给出的实验结果表明,和不采用分级编码的H.264/AVC编码器相比,该方案的增强层编码器可以降低视频传输所需带宽约20%～30%,计及传输基本层后,总比特率也仅比不分级的比特率约增加不到10%。
A scheme of space-grade hierarchical video encoder based on H.264 / AVC is proposed. The experimental results show that the enhancement-layer encoder of this scheme can reduce the complexity compared with the H.264 / AVC encoder without hierarchical coding Video transmission bandwidth required about 20% to 30%, taking into account the transmission of the basic layer, the total bit rate is only about a fraction of the bit rate increase of less than 10%.
