Recently, during FIBA Basketball World Cup, Beijing successfully applied "5G + 8K" technology.
Beijing Municipal Science and Technology Commission, together with relevant departments, carried out the demonstration application of "5G + 8K" technology live broadcast trial for games for the first time. For nine trials in Wukesong stadium, it comprehensively and systematically verified the reliability of 5G network transmission and 8K ultra-high definition video, and opened a new starting point for the whole industry chain.
It is understood that the world's first "5G + 8K" rebroadcast vehicle and 8K professional rebroadcast camera are used in the production of the event; in terms of network transmission, Nufront's EUHT network realize cross regional ultra-high-speed wireless transmission through two 5G networking modes NSA and SA, and transmit 8K pictures in the competition from Wukesong stadium to the designated broadcast and display site in real time.
As one of the proven transmission technologies, EUHT technology transmits the image of the broadcast signal of the Basketball World Cup through the Gehua cable TV network. "At the beginning of the design, EUHT takes into account the diversity of application scenarios. The system design is simple, flexible and efficient, with high throughput, high reliability, high speed mobility, low latency, low cost and low power consumption. It is an ultra-high-speed wireless communication technology, which can be widely used in high-speed rail, subway, rural wireless and other fields. In the live broadcast of the Basketball World Cup, the data transmission speed of EUHT reached more than 200MB per second, which verified the high-speed transmission of 8K Ultra HD video. " Lei Jun, vice president of technology of Nufront, said.
Under the leadership of Beijing Municipal Science and Technology Commission and other departments, through the EUHT uplink wireless channel of basketball stadium, Gehua cable TV backbone transmission network and the EUHT downlink wireless channel, Nufront and Gehua Group realize the complementary advantages sharing and resource sharing of both sides .
"This live broadcast trial has set a precedent for the application of" 5G + 8K "technology in world-class sports events, opened up the collaborative innovation of the whole industry chain of" 5G + 8K ", and played an unimaginable role in driving and promoting the industry." Zhang Hong, general manager of Ultra High-Definition Video (Beijing) Production Technology Collaboration Center, said.
