摘　　要：随着4K、8K的视频源越来越多,视频格式越来越大,视频会议系统的数据量也越来越大,视频传输和存储成为视频会议发展的瓶颈。如何有效地去除视频数据中的冗余信息,实现低带宽传输高清视频,是视频应用的一项关键技术。H.265标准在H.264标准的基础上,在帧间预测和帧内预测方面有了很大的提升,虽然对计算能力有更高的要求,但是随着计算设备的不断发展,H.265标准以其高效的编码能力必将成为主流。H.265编码技术能够在更低带宽下传输更高质量的动态视频,能够解决视频卡顿、延时、丢包等问题,在提高效率、节约带宽和存储空间方面优势十分明显。With more and more 4K and 8K video sources,larger and larger video formats,and larger and larger data volume of video conference system,video transmission and storage become the bottleneck of video conference development.How to effectively remove redundant information in video data and realize low bandwidth transmission of high definition video is a key technology in video applications.On the basis of H.264 standard,H.265 standard has greatly improved in inter prediction and intra prediction.Although it has higher requirements for computing power,with the continuous development of computing equipment,H.265 standard will become the mainstream with its efficient coding ability.H.265 coding technology can transmit higher quality dynamic video with lower bandwidth,and can solve the problems of video jam,delay and packet loss.It has obvious advantages in improving efficiency,saving bandwidth and storage space.
