UHD outdoor LED Advertising Screen industry market size is expected to reach 4 trillion yuan
According to statistics, by the end of 2021, there were 985 high-definition TV channels in China, 8 4K ultra-high-definition TV channels and 1 8K ultra-high-definition TV channel. The Central Radio and Television Station and 25 provincial TV channels basically realized high-definition, with 109 million high-definition and ultra-high-definition users. The State Administration of Radio and Television recently issued "Opinions on Further Accelerating the Development of High-Definition and Ultra-High-Definition Television" to actively promote the development of ultra-high-definition video industry. The market size is expected to reach 4 trillion yuan. Mr. Li of Dong'e County, Liaocheng City, Shandong Province, recently bought a 4K TV, originally just to have a better experience of watching movies and playing games, but when he turned on the new TV, he was pleasantly surprised to find that he could receive more high-definition and ultra-high-definition channels. Most CCTV channels and most local satellite TV stations have corresponding high-definition channels, and can also receive ultra-high-definition channels such as CCTV4K and CCTV8K, and even Liaocheng TV has achieved high-definition. The effect of UHD TV is so cool. Mr. Li said. "Opinions on Further Accelerating the Development of High-Definition and Ultra-High-Definition Television" put forward that by the end of 2025, TV stations at prefecture level and above and county-level TV stations with conditions will complete the transformation from standard-definition to high-definition, standard-definition channels will be basically shut down, high-definition television will become the basic broadcasting mode of television, and the supply of ultra-high-definition television channels and programs will form a scale. The carrying capacity of radio and television transmission coverage network for high-definition and ultra-high-definition television has been significantly enhanced, and high-definition and ultra-high-definition television receiving terminals have been basically popularized. Industry insiders pointed out that China's ultra-high definition video market has broad prospects, and the promotion of high-definition ultra-high definition channels can not only meet the growing needs of the audience, but also drive the development of 5G, AI and other related technologies. According to the research report of CCID Consulting, it is estimated that the direct sales revenue of ultra-high definition video products and services in China will exceed 2.5 trillion yuan in 2022, and with the application of various industries, the overall market scale is expected to be about 4 trillion yuan. The audience felt as if they were on the scene During the Beijing Olympic Winter Games, the outdoor screen of Beijing Contemporary Mall attracted the attention of passers-by. The outdoor LED Advertising Screen is 24 meters wide and 13.44 meters high, with a total area of 322.56 square meters. It simultaneously broadcasts the 8K ultra-high definition content of Beijing TV Winter Olympics documentary. Although the outdoor LED Advertising Screen is large, the picture is clear, the color is gorgeous, the visual effect is real, and the audience seems to be on the scene. It is reported that in order to complete the Beijing Olympic Winter Games relay work, the Central Radio and Television Station took the lead in developing a domestic 8K ultra-high definition camera system. Within the National Speed Skating Oval, the domestic 8K ultra-high definition camera system was successfully connected to the 8K broadcasting system, and successfully completed the broadcasting of all the Winter Olympic Games in the venue. The safety, reliability and functionality of its equipment are fully stress-tested for technical applications. For the first time, it has broken the situation that the front-end broadcast-level professional video recording equipment in the radio and television industry relies on imports. The relevant person in charge of the Central Radio and Television Station said. Technological innovation is ultimately implemented in content upgrading. The Forbidden City, a documentary co-produced by the Palace Museum and Beijing Radio and Television Station, was filmed with 8K ultra-high definition technology. Once broadcasted, it triggered extensive discussion, and the search volume and broadcasting heat ranked at the top of the main list of documentaries on major video websites. "The unique visual perception and more exquisite picture details brought by 8K shooting enable the audience to see history in the lens, expand the visual scope of the audience, and bring more imagination space." For example, when shooting the famous kiln porcelain of the Song Dynasty, the texture of the cultural relics was clearly presented on the outdoor led video wall, and the audience could intuitively feel the spirit of craftsmen behind the ancient craftsmen. Wen Xiaojun, Secretary-General of China Ultra High Definition Video Industry Alliance, believes that to accelerate the landing of the ultra high definition video industry, all links of the industry chain need to work together. Ultra HD content needs to be presented by a good display terminal. Zhao Bin, Vice President of TCL CSOT Technology Co., Ltd., introduced that the development of outdoor led display industry has experienced the industrialization operation of 2K and 4K, and has now reached the ecological establishment and growth period of 8K. The industry is focusing on promoting the cost reduction and efficiency enhancement of materials and design, and accelerating the popularization of 8K. Speed up the formulation of standard system Many viewers have the experience that when watching high-definition TV channels, there is a "high-definition" outdoor led advertising wall sign in the upper right corner, but the picture clarity and display effect are similar to those of standard-definition channels. The relevant person in charge of the State Administration of Radio and Television pointed out that according to the means of shooting and production, the so-called 4K video can be divided into "true 4K" and "pseudo-4K". "True 4K" format is 4K, and the video is shot and produced by 4K or higher format equipment. "Pseudo-4K" is the so-called 4K video obtained by low-resolution or low-frame rate conversion. There is a certain overlap between "true" and "false" 4K. How to tell whether a program is HD or not? Industry insiders pointed out First, the picture quality is different. The fineness of HD programs is 4 times that of SD programs, and the details are more abundant. Second, the display effect is different. ? Standard definition programs generally have a picture ratio of 4:3, and high-definition programs generally have a picture ratio of 16:9, which can perfectly adapt to the display effect of flat panel TV. Third, the sound effect is different. ? High-definition programs are generally stereo sound, and the sound effect is better. Wen Xiaojun believes that we should speed up the establishment of a comprehensive standard system for ultra-high definition video, promote the establishment of a group standard system for 4K end-to-end technology products, and promote the formulation and evaluation of ultra-high definition video content standards. Experts suggest that we should improve the technical standard system, monitoring and supervision system and quality supervision system of HD and UHD TV, strengthen standard publicity, monitoring and supervision and technical quality supervision, and ensure the healthy and orderly development of HD and UHD TV for the outdoor led advertising screen
