摘要近年来视频服务产业链的各大版面都充斥着4K,极致高清,但在网络传输带宽及存储空间有限的情况下传输、存储和显示视频却是一个难题。国际电联(I T U)推出新一代的视频编码HEVC/H.265,作为创新时代下全球视频编解码的主角。基于H.264,对比分析了H.265标准在编码结构、帧内预测、帧间预测以及熵编码等技术上的改进和算法上的优化,通过实验比较其在编码性能上的优越性。 Recently years, video service industry chain is filled with 4K, extreme high definition, but how to transmit, storage and display the video is a difficult problem. In early 2013, the ITU formally approved the new generation of video coding HEVC/H. 265 standard. As a kind of high efficient coding compression technology, it will be the role of global video encoding and decoding under the age of the innovation. Compared with H. 264, on the premise of maintaining the quality of basic, there was a 50% decrease in upload time and the demand for the bandwidth. It also supports resolution of 7680 × 4320. Based on H. 264, coding structure, intraframe prediction, interframe and entropy coding are analyzed for the improvement and optimization algorithm.
