From analog to digital standard definition, and then from HD to 4K, China’s video technology is about to enter the 8K era. According to the action plan for the development of ultra high definition video industry (2019-2022), by 2022, the total scale of ultra high definition video industry will exceed 4trillion yuan, the 4K industrial ecosystem will be basically improved, breakthroughs will be made in the R & D and industrialization of 8K key technology products, and a number of internationally competitive enterprises will be formed.
It is understood that the 2021 Spring Festival gala will be produced in 8K, and the live broadcast test will be conducted on the IPTV platform inside the head office in the form of 8K channel. In the past, the annual Spring Festival gala will focus on the innovative application of new technologies. After the 5g+4k/8k production and broadcasting demonstration platform is completed in 2021, the annual production capacity of the total UHD TV programs will reach 10000 hours.
At the same time, the general office of the State Administration of radio and television issued the implementation plan for the iteration of radio and Television Technology (2020-2022), promoting the development of high-definition simulcast to high-definition, shortening the transition period of simulcast, and gradually shutting down standard definition channels. The report points out that by the end of 2022, it is planned to basically realize the simultaneous broadcasting of central and provincial satellite TV programs on live satellite HD; The comprehensive HD upgrade in the field of transmission and broadcasting will further boost the development of China’s UHD video industry.
As China accelerates the promotion of UHD video applications and the advent of 5g era, it will comprehensively promote the rapid development of the content and application layer of UHD video industry. The UHD video industry will usher in a broad market prospect. It is expected that 4k/8k will enter every household in China with a high coverage rate. At the same time, with the development of technology and the improvement of transmission conditions, the demand for the clarity of security monitoring images is also increasing. Since the HD network camera began to challenge the traditional analog camera in 2010, HD has become the basic demand of many users, and users’ pursuit for clarity is increasing year by year.
For security monitoring, image definition is the key. The clearer the image, the more obvious the details, and the better the monitoring effect. The application of ultra-high definition video is to make the video monitoring move from “clear” to “clearer”. The ultra-high definition video shows the picture content more clearly and prepared, and accurately restores the monitoring scene.
For example, in the field of intelligent transportation, ultra-high definition video monitoring can accurately identify license plates, license plates and pedestrians on the road, and realize the intelligent analysis function of behavior and gait recognition; In the field of smart medicine, the ambulance is equipped with an ultra-high definition camera to capture the HD video of the patients in the car, which helps the medical experts to remotely master the situation of the patients, guide the medical staff in the car to carry out first aid, and prepare the surgical plan and surgical equipment in the hospital in advance according to the actual situation of the patients; In the field of UAV, the UHD equipment installed on the UAV can be used to monitor and track the target at high altitude, and can also be used for live broadcast of sports venues, activities and scenic spots.
The promotion and application of ultra-high definition video is a new round of major technological innovation in the field of security monitoring after the digitization and HD of video, which will accelerate the development of the field of security monitoring and promote the upgrading and transformation of the security monitoring system.
In general, during the “14th five year plan” period, the development of China’s ultra-high definition video industry will accelerate. The development prospect of China’s ultra-high definition video industry is bright. Security enterprises should also make preparations as soon as possible to boost the development of ultra-high definition video and popularize ultra-high definition video monitoring as soon as possible.
