摘要
超高清(UHD)视频能为用户带来质量更高、沉浸感更强的视觉体验,但高带宽成本限制了其推广和应用。为解决超高清视频传输和存储的难题,中国数字音视频编解码技术标准(AVS)工作组制定了新一代视频编码标准——AVS3,并在超高清产业化应用方面取得重要进展。介绍了AVS3视频编码关键技术,以及其与AVS2、多功能视频编码(VVC)、开放媒体联盟视频(AV1)等标准的性能对比情况。
Ultra-high definition(UHD)videos can provide users a higher quality and more immersive visual experiences.However,the application of UHD is limited by high bandwidth cost.To solve the transmission and storage problem of UHD,China Audio and Video Coding Standard(AVS)workgroup established a new generation of video coding standard—AVS3.Currently,AVS3 has made a great contribution to the development of UHD industries in China.Key technologies of AVS3 are described,and a comprehensive comparison with AVS2,versatile video coding(VVC)and alliance for open media video 1(AV1)is conducted.
