在数字视频应用产业链的快速发展中,面对视频应用逐步向高分辨率、高帧率、高压缩率方向发展的趋势,当前普遍采用的H.264视频压缩标准的局限性日益显现出来。 H.265标准是ITU-T VCEG继H.264之后所制定的新的视频编码标准。 H.265标准围绕着现有的视频编码标准H.264,保留了原来的某些技术,同时对部分技术加以优化改良。新标准使用先进的技术用以改进码流、编码质量、延时和算法复杂度之间的关系,进而达到性能最佳化。

In the rapid development of industrial chain of digital video applications,facing the trend of video applications gradually to the high resolution,high frame rate,high compression direction,the current widely used H. 264 video compression standard limitations is in-creasingly prominent. H. 265 standard is developed by ITU-T VCEG following the H. 264. The existing H. 265 around video coding standard H. 264,retains some of the original technique,while some technical improvements to be optimized. New standard uses advanced technologies to be used to improve the relationship among stream,encoding quality,delay and the complexity of the algorithm,to achieve the most optimal settings.
