On the evening of February 7th, in the men's short track speed skating1000m final held in the Capital Gymnasium, China's Ren He won the championship and runner-up respectively. Hungarian Liu Shaolin, who was the first to cross the finish line, was disqualified for a foul. After the game, netizens independently launched the "Thanks to Cheetah" activity. Everyone thought that this ultra-high-speed 4K track camera captured the athletes' "little moves", but in fact, others made meritorious deeds.

According to the website of the State Supervision Commission of the Central Commission for Discipline Inspection reported on February 8, Zhao Wei, the director of the second special equipment column broadcast by the Technical Bureau of CCTV General Station, clarified that "Cheetah" is located in the National Speed Skating Hall, known as "Ice Ribbon", and not in the Capital Gymnasium. And "Cheetah" is a special equipment for live TV broadcast. In the short track speed skating competition, an independent arbitration camera system was adopted, and the two penalties for short track speed skating on the evening of the 7th were also based on this video system.

In other words, it was the arbitration camera system that contributed to the short track speed skating men's 1000 meter final. It is reported that the system mostly includes multi-camera video recording and slow-motion playback system, which records the information of each athlete or each lap through the accurate shooting of fixed cameras, and can carefully analyze every movement of athletes in slow-motion mode.

The short track speed skating men's 1000m competition venue of the Capital Gymnasium is not equipped with the "Cheetah" camera system, but equipped with 40 4K camera arrays and 3 8KVR cameras, which is one of the applications to enhance the audience's viewing experience of the Winter Olympics. Like cheetahs, these cameras only play the role of live TV cameras, and the content of the images taken is not used for adjudication.

Cheetah runs faster than speed skaters.

The "Cheetah" thanked by netizens is a 4K high-speed camera independently developed by the Central Radio and Television General Station for five years, which belongs to the special equipment for live TV broadcast. Zhao Wei said in an interview with the media that it is called "cheetah" because it is very agile. In the speed skating competition of the Winter Olympics, the speed of athletes can reach 15 to 18 meters per second, which is about 50 kilometers per hour, while the speed of top athletes can reach 70 kilometers per hour. The design technical standard of "Cheetah" can reach 25 meters per second, which is about 90 kilometers per hour. "Cheetah" can also accelerate, decelerate and surpass according to the needs of live broadcast, thus capturing various scenes in speed skating competition more flexibly and casually.

Zhao Wei revealed that there is only one set of "Cheetah" system, which is installed in the "Ice Ribbon" venue. Because the high-speed track system has certain requirements for the venue, it is necessary to install the track system behind the sponge pads of athletes outside the stadium, and also install isolation plates to ensure the safety of people around. However, this short track speed skating venue does not meet the deployment requirements of cheetahs. For the sake of adaptability and safety, the cheetah system was not installed in the short track speed skating competition.
