Recently, the popular video website Bilibili (Station B) announced that it has officially launched the 8K video function, and the video website has officially entered the 8K ultra-high-definition era. In addition, in order to achieve the "Science and Technology Winter Olympics 8K Olympic Games", according to the plan, CCTV will officially launch the 8K ultra-high-definition TV channel in December, and realize the whole process from content production to editing and broadcasting, and the 8K ultra-high-definition standard operation is realized.
In addition to CCTV, local TV stations are also eager to try to open 8K channels. Earlier this month, the Beijing Municipal Bureau of Radio and Television issued the "Opinions on Promoting the High-quality Development of Radio, Television and Online Audio-Visual", which proposed to promote 5G+8K+ interactive video, open an 8K pilot channel, and promote the construction of the "Winter Olympics Ultra-high-definition 8K Digital Retransmission Technology and System" project. Guangzhou proposed that by 2022, the scale of Guangzhou's ultra-high-definition video and digital content industry will exceed 400 billion yuan, and 5G+4K/8K ultra-high-definition video will widely enter daily life scenes.
This means that an era of "8K for all" has slowly begun. It is reported that the resolution of 8K video is 7680×4320 pixels, and the pixels reach 33 million, which is four times that of 4K video and 16 times that of the current mainstream HD video. This allows 8K to deliver skin, texture, light, and texture details far beyond 4K, giving viewers an unparalleled sense of immersion through what can be called "fine-grained" images.
With the promotion and application of 5G, 8K and other technologies, ultra-high-definition video has ushered in a golden period of development. Statistics from the China Electronics Information Industry Development Institute show that in 2020, the direct sales revenue of China's ultra-high-definition video production and terminal presentation will exceed 850 billion yuan, driving the hardware sales and application scale of vertical industries to exceed 930 billion yuan, with a total scale of 1.8 trillion yuan.
From the policy level, the "Ultra-high-definition Video Industry Development Action Plan (2019-2022)" clearly states that by 2022, the overall scale of China's ultra-high-definition video industry will exceed 4 trillion yuan, the sales volume of 8K TV terminals will account for more than 5% of total TV sales, the supply capacity of 4K channels will be greatly improved, the production capacity of ultra-high-definition programs will exceed 30,000 hours / year, and the 8K production and broadcasting trials of Beijing Winter Olympic games will be carried out, and the number of ultra-high-definition video users will reach 200 million. In order to implement the action plan, the Ministry of Industry and Information Technology and other six departments also launched the "100 Cities and 100 Screens" ultra-high-definition video landing promotion activity in October this year.
The Ministry of Industry and Information Technology, the Central Propaganda Department and other six departments recently deployed to carry out the "100 cities and 100 screens" ultra-high-definition video landing promotion activities. With the theme of "Lighting Up 100 Cities and 100 Screens, Dazzling And Ultra-Clear Vision", the event supports qualified cities to set up ultra-high-definition public large screens, enhances the penetration of the ultra-high-definition video industry through the exhibition and broadcast of high-quality ultra-high-definition video content, and accelerates the integration and innovation of ultra-high-definition video in many fields.
With the acceleration of the commercialization of 5G technology, problems such as uneven development of the ultra-high-definition video industry and weak industrial support will be solved. In the next 3 to 5 years, China's ultra-high-definition industry will be more mature from the production of upstream equipment such as high-definition panels and video production, to the construction of transmission systems such as set-top boxes and optical fibers, and then to the production of downstream content.
