On 23 March 2021, the National Radio and Television Administration (NRTA) published four standards system documents, specifically for 5G high-tech video on interactive video, immersive video, VR video and cloud games. The documents will give full play to the role of standards in guiding and regulating 5G high-tech videos; they will also contribute to the high-quality and innovative development of the radio, television, and network audio-visual industries.
In 2020, the 2020 White Paper Series of 5G High-tech Video Technology was officially released by NRTA for the first time. It systematically summarized the technologies and principles of the application of 5G high-tech video in the industry. Specifically, high-tech video refers to “high-format, new concept” video in 5G network environment: within this, “high format” refers to the video integrated with 4K/8K, 3D, VR/AR/MR, high frame rate, high dynamic range, wide color gamut and other high-tech formats; while “new concept” refers to an innovative application scene with novel image language and visual experience, which can arouse the interest of the audience. The word “high-tech video”, which is one of the top 10 sci-tech keywords of China’s radio and TV industry in 2020, has also been highlighted in important national policy documents, including the Opinions of the General Office of the State Council on Accelerating the Development of New Types of Consumption Driven by New Business Forms and Patterns.
In general, the standards for 5G high-tech videos mainly cover: (i) foundation; (ii) content production and broadcast; (iii) security; (iv) security; and (v) quality evaluation. Based on the documents, GY/T 332—2020 (sector standard-Specification of data format for interactive video over the Internet) has already been published. And there are also 34 additional standards under development for interactive video, immersive video, VR video and cloud game.
