CCTV, China Mobile and Huawei successfully carried out the first 4K transmission test of 5G network. It is expected that 4K ultra-high definition content 5G network transmission will be realized for the first time in Shenzhen Branch of CCTV Spring Festival Gala this year.

On January 10, Miao Wei, Minister of Industry and Information Technology, said in an interview with the media that in 2019, China will issue 5G temporary licenses in several cities, so that large-scale networking can take the lead in some cities and hot spots.

"5G will help broadcasting and television to realize the desire of pulling users back to the TV set. This is a signal to speed up the 5G process, which is of great benefit to China's 4K ultra-high definition television broadcasting and television industry, which is undergoing transformation and upgrading."

Ultra-High-Definition (Ultra-High-Definition) is the name of the information display "4K resolution (3840*2160 pixels)" approved by the International Telecommunication Union. Ultra-High-Definition TV service has high requirements for integrated user experience including end-to-end bandwidth, delay and packet loss. The characteristics of 5G such as "high speed, low delay and large capacity" will provide large-scale application of Ultra-HD video technology. Necessary foundation.

With the approaching of global 5G commerce, the trend of UHD is sweeping the world. According to the prediction of relevant institutions, the development of UHD video in China will bring about an increase of 2.5 trillion yuan in industrial scale from 2018 to 2022. Among them, the output value of UHD video related services will reach 550 billion yuan.

Jonathan Wood, General Manager of Business Development and Cooperation in Intel 5G's Next Generation and Standards Division, said: "5G will inevitably shake the media and entertainment landscape. Keeping pace with the times, it is a big competitive asset. Otherwise, it will be in danger of failure or extinction.

According to China Mobile, on December 28, 2018, China's first national-level new media platform based on 5G technology was established at CCTV. At the same time, CCTV signed a framework agreement for the construction of 5G new media platform with three major telecom operators and Huawei to support 4K UHD video transmission, 4KVR live production and 4K video mobile editing based on 5G network. As well as 4K channel mobile phone projection screen and other application experiments.

At present, the cooperation has preliminarily completed the planning and design of the laboratory and system preparation. The laboratory will be launched during the two sessions this year, and will simultaneously carry out 5G live broadcasting of 4K UHD video signals in 10 pilot cities.
