DVBCN Digital Television Chinese Network News (Ao Rui), on June 6, the General Administration of Radio and Television issued a notice: The industry standard "Advanced Audio and Video Codec for Broadcasting and Television Part 1: Video" has passed review.
It is reported that the Science and Technology Department of the General Administration and the National Radio and Television Standardization Technical Committee held a standard review meeting in Beijing on June 1.
The expert committee reviewed the introduction from the standard drafting group regarding the standard preparation instructions, handling of feedback, intellectual property report, and testing report. They conducted a chapter-by-chapter and item-by-item examination of the draft standard and provided corresponding suggestions for revisions. The committee agreed to approve the standard for review.
The approval of the video standards in the broadcasting industry marks a new stage in the advancement of China's second-generation source coding standard AVS, which is based on independent intellectual property rights.
AVS is China's second-generation source coding standard with independent intellectual property rights. As the name suggests, "source" refers to the "origin" of information. The key issue addressed by source coding technology is the encoding and compression of massive digital audio and video data (i.e., the original data, or source), which is why it is also referred to as digital audio and video coding technology. It is evident that this is the first step in subsequent processes such as digital information storage, transmission, and playback, making it a common foundational standard for the digital audio and video industry.

The Audio Video Coding Standard Working Group (referred to as the AVS Working Group) was established in June 2002 with the approval of the Science and Technology Department of the Ministry of Information Industry of China. The mission of the working group is to address the needs of China's information industry by collaborating with domestic enterprises and research institutions to formulate (revise) common technical standards for the compression, decompression, processing, and representation of digital audio and video. This aims to provide efficient and economical coding and decoding technologies for digital audio and video devices and systems, serving major applications in the information industry such as high-resolution digital broadcasting, high-density laser digital storage media, wireless broadband multimedia communications, and internet broadband streaming media.
