摘　　要：新一代视频编码标准HEVC更倾向于处理高清视频,实现在设备复杂度有一定增加的前提下提高视频,尤其是高清视频的编码效率。结合现行的H.264标准,对比了HEVC标准在编码结构、帧内预测、帧间预测以及熵编码技术上的改进和算法上的优化。对HEVC的具体编码技术进行分析,并将HEVC与H.264编码性能进行了比较。实验结果表明,HEVC在编码性能上有了明显提高。The new video coding standard, HEVC, mainly focuses on video processing, improving coding efficiency of video, especially HD video, with certain increase of coding equipments. Through comparing with H.264 standard, the improvements and optimized algorithms are summarized in fields of coding structures, intra prediction, inter prediction and entropy coding. The experiment results indicate that the performance of HEVC is improved significantly compared with H.264. In view of processing larger size videos, the enhancement of coding performance is more obvious.
