Brand Manager Zhang Zheng Column: [correspondents] Xiao Xiao “China Security”: H.265 as a new generation of video Compression technology, compared with H.264, performance optimization? Liang Liwei: H.265 is the latest generation of video by ITU-T’s video coding expert group VCEG and ISO / IEC’s Moving Picture Experts Group MPEG jointly launched Encoding standard, which is designed to double the compression efficiency of the previous generation H.264 standard, which means that the same bit rate of H.264 video is half the same. According to the video subjective quality test results released at the 17th JCT-VC meeting concluded in April 2014, with a bit rate reduction of 52% to 64%
