The National Radio and Television Administration recently revealed that it plans to launch 13 new ultra high definition channels, including CCTV and provincial-level satellite TV, nationwide by the end of 2025, bringing the total number of ultra high definition channels in China to over 20. Moreover, ultra high definition programs will gradually become mainstream on online audiovisual platforms such as iQiyi, Youku, and Tencent. The so-called ultra high definition video refers to a new generation of video with 4K or 8K resolution that meets technical requirements such as high frame rate, high bit depth, wide color gamut, and high dynamic range. During the Paris Olympics, ultra high definition videos allowed sports fans to experience the exciting moments of the competition firsthand; Sanxingdui Archaeological Live allows netizens to immerse themselves in viewing national treasures, thanks to the innovative application of ultra high definition video technology. These are typical application cases in the field of ultra high definition video. Ultra high definition video has not only emerged in fields such as broadcasting and television, culture and entertainment, but also has broad application prospects in security monitoring, medical imaging and other fields. Many years ago, foreign technology companies competed to layout the ultra high definition video industry. In recent years, the State Administration of Radio and Television, the Ministry of Industry and Information Technology, and other departments have successively issued multiple policies to promote the "ultra high speed" development of ultra high definition videos in China. Currently, ultra high definition video technology has accelerated its penetration into various fields of the economy and society, becoming an important engine for cultivating and developing new quality productivity. From the demand side, developing ultra high definition videos helps meet people's demand for high-quality audiovisual programs. From early black and white screens to today's color high-definition smart TVs, technological advancements have made people's entertainment lives increasingly rich and colorful. The breakthrough and application of ultra high definition video technology will further change the way people watch TV, bringing users an immersive audio-visual experience and better meeting their growing spiritual and cultural needs. From the perspective of production, the development of ultra high definition videos is an important direction for improving the quality and upgrading of broadcasting and television, which is of great significance for expanding domestic demand, promoting cultural industry and digital economy development. The development of ultra high definition video industry can directly drive the overall iteration and upgrading of the production and broadcasting equipment, terminal products, display panels, chips and other industrial chains, promoting digital technology innovation and content creation prosperity. Promoting innovation in ultra high definition technology and product applications can also help boost bulk consumption such as electronic products. With the deep integration of technologies such as 5G, AI, VR/AR, and ultra high definition video technology, a large number of new scenarios, applications, and models will emerge, continuously promoting the prosperity and development of the cultural industry. Technological innovation is the fundamental guarantee for the rapid development of industries. China's video technology has evolved from learning from standard definition and catching up with high-definition, to now achieving some independent core technologies in the ultra high definition field that are at the world's advanced level, fully reflecting the importance of independent innovation. In the future, the field of ultra high definition video will also strengthen collaborative innovation across the entire industry chain, including core components, key equipment, and display terminals. Through technological iteration, it will promote consumption upgrading and form more new economic growth points. The ability to provide ultra high definition video content directly determines the speed and level of industrial development. Currently, ultra high definition video technology is advancing rapidly, but there is still a shortage of high-quality content that cannot meet market demand. The field of content creation needs to quickly adapt and keep up with the pace of technological development, constantly enriching the supply of content related to ultra high definition videos. Only by adhering to the dual wheel drive of technological innovation and content innovation, and integrating culture and technology, can we further stimulate the greater potential of the ultra high definition video industry.
