The document specifies the syntax description, semantic description, and packaging definition of the efficient multimedia encoded picture file format, which is suitable for dynamic images, static images and other application fields in Internet multimedia, games, and digital media services.
Since the establishment of the AVS working group in my country in June 2002, with the team efforts of thousands of people for more than ten years, AVS with independent intellectual property rights in my country came into being. AVS3 is the world’s first launched video coding standard for 8K and 5G industrial applications.
AVS International Team Leader Zheng Jianhua previously revealed that AVS has started the standard formulation of AVS4, and called on AVS member units to continue to support the development of AVS's next-generation standard, and various manufacturers to unite to realize the technology Standards go overseas together to promote global deployment.
The above is the detailed content of my country's 6 national standards for AVS multimedia coding and virtual reality were promulgated, and Tencent, Alibaba, Samsung, HiSilicon, etc. participated in the preparation.
