The DVB Project announced that it approved AVS3 from China as one of the next-generation ultra-high-definition video coding standards, aiming to promote the application and development of 4K/8K broadcast and broadband TV industries. This is also the first time that DVB adopts video standards from China.
The DVB organization is responsible for the development of digital broadcasting technology standards such as satellite, cable, terrestrial, and broadband networks. Its standards are issued by the joint technical committee of the European Telecommunications Standards Institute (ETSI), the European Committee for Electrotechnical Standardization (CENELEC), and the European Broadcasting Union (EBU). At present, more than 150 organizations in 25 countries have joined the DVB system, and relevant technical standards are widely used around the world.
The DVB organization started the next-generation codec specification work in May 2020 and announced three candidate codec specifications for 4K/8K broadcast and broadband TV in July 2021, and AVS3 is one of them. Test results show that compared with HEVC, the AVS3 codec can save about 40% of the bit rate under the same picture quality, which makes AVS3 among the most efficient video coding technologies in the world.
China’s AVS working group was established in 2002, in which the first and second-generation AVS video coding has been widely used in Chinese HDTV and 4K TV broadcasting. The AVS3 standard development work started in December 2017 and the main profile was completed in March 2019, and is the latest member of the family of video coding standards developed by the AVS workgroup. The high profile currently adopted in DVB-AVC is to be completed in August 2021 and released as an AVS industry standard.
