According to news from this site on June 4, on May 28, the State Administration for Market Regulation (National Standardization Administration Committee) issued China National Standards Announcement No. 9 of 2024, approving 195 recommended national standards and 1 national standard. Standard revision sheet.
This site noticed that the revision order includes 6 national standards organized and revised by the AVS working group, 5 of which are national standards in the "Information Technology Efficient Multimedia Coding" series, and 1 It is the AVS virtual reality national standard "Information Technology Virtual Reality Content Expression Part 2: Video".
The details of the six AVS national standards promulgated this time are as follows:
"Information Technology Virtual Reality Content Expression" Part 2: Video》
Standard number: GB/T 44115.2-2024
by Peking University Shenzhen Graduate School, Peng It was jointly compiled by 21 units including City Laboratory, Peking University, University of Science and Technology of China, and Alibaba (China) Co., Ltd.
The document specifies the coding representation and reconstruction method of virtual reality panoramic video and free-view video, including the syntax, semantics and reconstruction process of the compressed domain, as well as the interface with the flat video coding standard, Suitable for virtual reality video content production, broadcast, transmission and other applications.
"Information Technology Efficient Multimedia Coding Part 2: Video"
Standard number: GB/T 33475.2-2024, replacing GB/T 33475.2-2016
This product was developed by 27 companies including Peking University, Zhejiang University, Beijing Samsung Communication Technology Research Co., Ltd., Shenzhen HiSilicon Semiconductor Co., Ltd., and Zhongguancun Audiovisual Industry Technology Innovation Alliance Prepared jointly by the units. This product is jointly developed by 27 organizations including Peking University, Zhejiang University, Beijing Sanxing Communication Technology Research Co., Ltd., Shenzhen Hisilicon Technologies Co., Ltd., and Zhongguancun Audiovisual Industry Technology Innovation Alliance.
This standard will replace "Information Technology Efficient Multimedia Coding Part 2: Video" (Standard Number: GB/T 33475.2-2016).
The document specifies the decoding process of an efficient video compression method that adapts to various bit rates, resolutions and quality requirements. It is suitable for broadcast television, digital movies, online television, online video, digital storage media, still images, etc. Video encoding.
"Information Technology Efficient Multimedia Coding Part 4: Conformity Testing"
- ##Standard number: GB/T 33475.4-2024
- was jointly compiled by 11 units including China Electronics Technology Standardization Institute, Pengcheng Laboratory, Beijing Atmos Information Technology Co., Ltd., Shenzhen DJI Innovation Technology Co., Ltd., and Tsinghua University.
"Information Technology Efficient Multimedia Coding Part 5: Reference Software"
- ##Standard number: GB/T 33475.5-2024
- was jointly compiled by 11 units including China Electronics Technology Standardization Institute, Pengcheng Laboratory, Huawei Technologies Co., Ltd., Peking University, and Beijing Atmos Information Technology Co., Ltd.
- The document defines reference software that meets the requirements specified in GB/T 33475.2-2016 and GB/T 33475.3-2018, and is suitable for digital TV broadcasting, interactive storage media, and live satellite video services , multimedia mail, packet network multimedia business, real-time communication business, remote video monitoring and other application system development, debugging and acceptance.
- Standard number: GB/T 33475.6-2024
- was jointly compiled by 10 units including Shanghai Jiao Tong University, Beijing Samsung Communications Technology Research Co., Ltd., Peking University, Beijing University of Technology, and ZTE Corporation.
- The document specifies intelligent media transmission technology for multimedia data transmission under heterogeneous packet switching networks, covering data model, data transmission, signaling, media rendering, HTTP/2 live broadcast and Adaptive forward error correction coding and other content are suitable for applications such as network streaming media, Internet TV and video on demand.
- Standard number: GB/T 33475.7-2024
- is jointly compiled by Tencent Technology (Shenzhen) Co., Ltd., Peking University, Pengcheng Laboratory, Zhongguancun Audiovisual Industry Technology Innovation Alliance and other units.
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.
