What communication network should be built to provide these services for the Winter Olympics?

Take the game broadcast as an example. In order to help the global audience better enjoy the live broadcast of the event, the Winter Olympics fully adopts 8K ultra-high-definition live broadcast, and introduces video technologies such as "free viewing angle" and "bullet time". With the help of "free viewing angle" technology, when watching the game through TV, mobile phone or VR equipment, the audience can "direct the broadcast" by themselves, change the viewing angle at any time, and enjoy the wonderful performance of the athletes in all directions. With the help of "bullet time" technology, the audience can also "freeze time and space" and feel the wonderful moments during the game. This interactive and immersive viewing experience not only puts high demands on the on-site shooting technology, but also brings severe challenges to the processing and transmission of video signals. The communication network of Beijing Winter Olympics should not only meet strict requirements in performance indexes such as speed, bandwidth and delay, but also be watertight in safety and reliability. In addition, based on the national strategy of "double carbon", the communication network must also meet the requirements of low energy consumption and environmental protection.
