The Digital Video Broadcasting Project (DVB Project) announced today that it has officially approved China’s “AVS3” as one of the next-generation video codec standards in the DVB standards system. The DVB Project is responsible for the development of digital broadcasting standards for satellite, cable, terrestrial, and broadband networks, and has been widely adopted worldwide, with more than 150 organizations from 25 countries joining the DVB system.
In July 2021, DVB announced three candidate codec specifications for 4K/8K broadcast broadband TV, and AVS3 is one of them.
After nearly two years of promotion by AVS Industry Alliance, AVS Working Group, Shanghai Heisi, Huawei, Shanghai National Engineering Research Center for Digital TV, Peking University, Pengcheng Laboratory and other organizations and enterprises bidding, AVS3 video standard T/AI 109.2-2021 and AVS3 system standard T/AI 109.6-2022 were finally recognized by DVB and incorporated into the standard system and completed the related work 6 months ahead of schedule.
Currently, two DVB Blue Book specifications containing the AVS3 standard have been revised and approved by the DVB Steering Committee meeting, namely the A001 Audio-Video Coding Available Specification (DVB-AVC) and the A168 IP Network Adaptive Streaming Transport Specification (DVB-DASH).
New versions of these DVB Blue Book specifications will be released soon and will further be followed by new versions of the corresponding European Telecommunications Standardization Institute standards, ETSI TS 101 154, TS 103 285, respectively.
DVB’s test results show that AVS3 can save 40.09% of the code rate compared to HEVC (H.265) at the same picture quality, praising it as one of the most efficient video coding technologies in the world.
In 2002, China established the AVS working group, which developed the first generation AVS video coding widely used for HDTV and 4K TV broadcasting in China.
Work on the AVS3 Ultra HD video coding standard started in December 2017, and the mainstream picture quality specification (main profile) will be completed in March 2019, and the high-quality specification (high profile) will be completed in August 2021 and officially released in October 2021.
AVS working group leader Academician Gao Wen said, “AVS3 is an encoding standard for 4K/8K UHD applications, with an encoding efficiency about twice as high as the previous generation of standards, and is the first officially released standard of its kind internationally.”
