On March 29th, the China Ultra-High-Definition Video Industry Development Conference was held in Guangzhou. The conference was organized by the Ministry of Industry and Information Technology, the State Administration of Radio, and the People's Government of Guangdong Province, the Guangdong Provincial Commission of Economics and Information Technology and the Guangdong Bureau of Press, Publication, Radio, Film and Television , Guangdong Provincial Communications Administration, Guangzhou Municipal People’s Government, China Electronic Information Industry Development Research Institute and China Ultra-High-Definition Video Industry Alliance. Ding Wenhua, Academician of Chinese Academy of Engineering attended the conference and published the title of “4K/UHD Times New Opportunities for Industrial Development” Presentation. Ding Wenhua said that the 4K/UHD industry chain includes three links: content production, network transmission and terminal viewing. In terms of content production, movies, film and television dramas, sports events and variety shows have become hot items around the world. In the category, 4K terminal display devices are not single, there are UHD, HDR and laser display devices. He also pointed out that the development direction of digital high-definition is driven by the back-end consumer industry, promote new transmission mechanisms and generate more content, ie Content-end-operated programs: Creating demand from the content end, establishing a transmission system, and driving the terminal For this reason, the perfection of digital copyright protection technology (DRM) is more important because it protects the content protection of terminal protection terminals. He believes that this move creates a good environment for the healthy development of 4K industry. Ding Wenhua affirmed the recent years China's related results in the 4K/UHD industry chain. In terms of standardization, Guangdong Province began to establish a series of end-to-end technical standards as early as 2004. In terms of radio and television networks, existing channels for dissemination can be provided in a timely and effective manner. 4K network transmission service. In addition, AVS2 encoding technology with domestic intellectual property rights has also been par with international popular HEVC performance. In addition, the Ministry of Industry and Information Technology promotes a 100M home broadband network, which basically can provide a smooth 4K viewing experience. The upgrading of China's next-generation basic network infrastructure is critical to the development of the 4K industry. The popularization of 100M home broadband still requires relevant departments to continue to promote speed-up and fee-reduction policies. In 2017, the output of 4K TVs in China has reached 3300 million units, accounting for 4K in the world. 42% of the total TV sets. In 2020, the number of global 4K homes will exceed 330 million, and China will become the world’s largest 4K TV consumer market. This shows that China’s ultra-high-definition video industry will enter a period of rapid development. Ding Wenhua put forward three proposals for the development of China’s 4K/UHD industry: First, the industry chain still needs to obtain content, network, and terminal companies in the three major parts of the unanimously approved The three parties should work together to promote the overall development of the industrial chain. Second, the basic industrialization conditions for China to promote 4K/UHD are basically met. The second half of 2018 will accelerate the industrial deployment. The third is the development of China's 4K/UHD in the next five years. In the golden period, the industry should seize the opportunity to ensure the global leading position of China's electronic consumer industry.
