数字视频广播组织(DVB Project)今天宣布,正式批准中国的“AVS3”成为DVB标准体系中下一代视频编解码标准之一。这也是DVB第一次吸纳中国视频标准。

DVB组织负责制定卫星、有线、地面和宽带网络等数字广播技术标准,在全球范围内得到广泛采用,已有25个国家的150多个组织加入到DVB体系中。

2020年5月,DVB启动下一代编解码规范工作。

2021年7月,DVB宣布了4K/8K广播宽带电视的三个候选编解码规范,AVS3就是其中之一。

在AVS产业联盟、AVS工作组、上海海思、华为、上海数字电视国家工程研究中心、北京大学、鹏城实验室等各方面组织、企业竞购近两年的推动,AVS3视频标准T/AI 109.2-2021、AVS3系统标准T/AI 109.6-2022最终得到了DVB的认可,被纳入标准体系,并提前6个月完成相关工作。

目前,包含AVS3标准的两份DVB蓝皮书规范已经完成修订,并由DVB指导委员会会议批准,分别是A001可音视频编码规范(DVB-AVC)、A168 IP网络自适应流媒体传输规范(DVB-DASH)。

这些DVB蓝皮书规范的新版本很快就会发布,后续将进一步成为相应的欧洲电信标准化协会标准的新版本,分别为ETSI TS 101 154、TS 103 285。

DVB的测试结果显示,AVS3相比于HEVC(H.265)可以在同等画面质量下节省40.09%的码率,称赞其是世界上最高效的视频编码技术之一。

2002年,中国成立AVS工作组,其制定的第一代AVS视频编码广泛用于中国HDTV、4K电视广播。

AVS3超高清视频编码标准工作2017年12月启动,2019年3月完成主流画质规范(main profile),2021年8月完成高画质规范(high profile),2021年10月正式发布。

AVS工作组组长高文院士表示:“AVS3是面向4K/8K超高清应用的编码标准,编码效率比前一代标准高一倍左右,是国际上第一个正式发布的同类标准。”

The Digital Video Broadcasting Organization (DVB Project) announced today that it has officially approved China’s “AVS3” as one of the next-generation video codec standards in the DVB standard system. This is also the first time that DVB has absorbed Chinese video standards.

The DVB organization is responsible for formulating digital broadcasting technology standards such as satellite, cable, terrestrial and broadband networks, which are widely used around the world. More than 150 organizations in 25 countries have joined the DVB system.

In May 2020, DVB started work on the next-generation codec specification.

In July 2021, DVB announced three candidate codec specifications for 4K/8K broadcast broadband TV, AVS3 being one of them.

Driven by the AVS Industry Alliance, AVS Working Group, Shanghai HiSilicon, Huawei, Shanghai Digital TV National Engineering Research Center, Peking University, Pengcheng Laboratory and other organizations and enterprises bidding for nearly two years, the AVS3 video standard T/AI 109.2-2021, AVS3 system standard T/AI 109.6-2022 was finally recognized by DVB and included in the standard system, and related work was completed 6 months ahead of schedule.

At present, two DVB Blue Book specifications including the AVS3 standard have been revised and approved by the DVB Steering Committee meeting, namely A001 Audio and Video Coding Specification (DVB-AVC), A168 IP Network Adaptive Streaming Media Transmission Specification (DVB-DASH) ).

The new versions of these DVB Blue Book specifications will be released soon, and will further become new versions of the corresponding European Telecommunications Standards Institute standards, namely ETSI TS 101 154 and TS 103 285.

DVB test results show that compared with HEVC (H.265), AVS3 can save 40.09% of the bit rate under the same picture quality, which is praised as one of the most efficient video coding technologies in the world.

In 2002, China established the AVS working group, and the first-generation AVS video coding developed by it is widely used in HDTV and 4K TV broadcasting in China.

The AVS3 UHD video coding standard work was started in December 2017, the main profile was completed in March 2019, the high profile was completed in August 2021, and it was officially released in October 2021.

Academician Gao Wen, head of the AVS working group, said: “AVS3 is a coding standard for 4K/8K ultra-high-definition applications. The coding efficiency is about double that of the previous generation standard. It is the first officially released international standard of its kind.”
