What digital technologies are used in the Winter Olympics? Why are the competitions of skaters so clear?

From the TV, it seems that there are more than unmanned kitchens, unmanned high-speed trains, epidemic prevention robots and memory beds ... All of these make people really feel the scientific and technological atmosphere of the Winter Olympics. There is also an army of robots: atomizing disinfection robots, robot waiters, epidemic prevention robots, inspection robots, and cute robots will identify people who don't wear masks. If you don't wear a mask, you should immediately rush to the front to remind you.

From ordering to taking meals, the restaurants in Beijing Winter Olympics are all served by machines, intelligent ordering systems and intelligent transmission equipment, which minimizes the close contact between people. About 120 catering machines, such as Hamburg robot, wok robot, clay pot robot and even coffee robot, bring you a brand-new experience. After guests order food intelligently, robots can make hamburgers, French fries and even kung pao chicken and Dongpo meat, which are "taught" by world famous chefs, and then "fall from the sky" through intelligent transmission equipment to meet the dining needs of athletes from all over the world and realize contactless intelligent food delivery.

Commuting between the three competition areas of the Winter Olympics is handled by Fuxing intelligent motor train with a speed of 350 kilometers per hour. The train integrates high-speed rail, 5G and 4K technologies, builds the world's first high-speed rail 5G ultra-HD Olympic studio, realizes the live broadcast of 5G HD events, and has the 4K live broadcast capability of 6 channels.

The cheetah system is set in the National Speed Skating Hall. This equipment, which was developed by CCTV for five years, consists of spiral rail cars and 360-meter-long U-shaped tracks, and is specially used for the broadcast of speed skating events in the Winter Olympics. Cheetah's camera system adopts 4K ultra-high definition resolution, which is four times that of 1080p, and can bring the most realistic visual experience to the audience. In terms of speed, the design technical standard of this camera system can reach 25 meters per second, which is about 90 kilometers per hour. The average speed of speed skaters is 50 kilometers per hour, so Cheetah can easily keep up with the skaters, speed up, slow down and overtake according to the broadcast demand, capture the game pictures flexibly, and provide us with the most wonderful moments. I believe these technologies will be applied to each of us soon, because every Olympic Games is a weather vane, which indicates the future development direction.
