软件和硬件中不断增长的处理能力推动了视频压缩技术的进步。新兴的高效视频编码（HEVC）标准旨在提供相对于H.264/AVC高配置文件的两倍的编码效率，以一半的比特率提供相同的视频质量。在本文中，复杂性相关的方面，在标准化过程中考虑的描述。此外，参考软件和优化软件的剖析给出了HEVC可能比其前身更复杂以及可能更简单的指示。总体而言，HEVC解码器的复杂度似乎与H.264/AVC解码器的复杂度没有显著差异;这使得HEVC解码在当前硬件上非常实用。HEVC编码器预计比H.264/AVC编码器复杂数倍，并将成为未来几年的研究主题。
Advances in video compression technology have been driven by ever-increasing processing power available in software and hardware. The emerging High Efficiency Video Coding (HEVC) standard aims to provide a doubling in coding efficiency with respect to the H.264/AVC high profile, delivering the same video quality at half the bit rate. In this paper, complexity-related aspects that were considered in the standardization process are described. Furthermore, profiling of reference software and optimized software gives an indication of where HEVC may be more complex than its predecessors and where it may be simpler. Overall, the complexity of HEVC decoders does not appear to be significantly different from that of H.264/AVC decoders; this makes HEVC decoding in software very practical on current hardware. HEVC encoders are expected to be several times more complex than H.264/AVC encoders and will be a subject of research in years to come.
