引言在安防监控行业的快速发展中,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。目前安防行业中H.264算法的应用已十分普及,从H.264发
Introduction In the rapid development of security monitoring industry, facing the trend of video application gradually developing toward high resolution, high frame rate and high compression ratio, the limitation of H.264 video compression standard which is widely used nowadays has become increasingly apparent. The H.265 standard is the new video coding standard developed by ITU-T VCEG after H.264. H.265 standard revolves around the existing video coding standard H.264, retaining some of the original technology, while some of the technology to be optimized and improved. The new standard uses state-of-the-art technology to improve the relationship between codestream, code quality, latency and algorithmic complexity to optimize performance. The security industry in the H.264 algorithm has been very popular applications, from the H.264 hair
