China’s Ren Ziwei and Li Wenlong won the men’s 1,000m short track speed skating final at the Beijing Winter Olympics on Sunday night after the Hungarian skater was disqualified for foul play.When the whole network boiling, many netizens launched a “thank you ‘cheetah'” activity.It is believed that the 4K high-speed camera named “Cheetah” captured the entire race and caught the “little moves” that were hard to detect in the high-speed travel, enabling China to win the gold medal with its strong strength and down-to-earth and clean competitive spirit.Instead of the Cheetah camera system, 40 4K camera arrays and three 8KVR cameras were installed at the Capital Stadium.Both serve only as live television footage, and their footage is not used for adjudication.Zhao Wei, head of the special equipment department of the second broadcasting Department of the Technology bureau of China Central Television, clarified that the “Cheetah” was just special equipment for live TV broadcast, and that the independent arbitration camera system used in the short track speed skating competition was also based on the video system, the website of the CPC Central Commission for Discipline Inspection and the National Supervisory Commission reported Wednesday.China’s short-track speed skating team won gold, prompting a frenzy of “thanks to cheetahs” from netizens’ memes: “Let’s see who dares to foul!”As the men’s 1,000m short track speed skating final was decided last night, many Internet users gave thanks to a super-high speed 4K track camera system called Cheetah.As the crowd debated whether Hungary’s Liu Shaolin had committed a foul, several cameras from different angles clearly showed him blocking his arm at the finish line.In the live broadcast of different scenes, the referee at the scene made a ruling after watching the video, judged Liu Shaolin to be disqualified for foul play, and the Clean Chinese team won the gold medal.Netizens gave the cheetah the credit, believing it had taken live footage to be used for refereeing decisions.”Cheetah”, as it is called by netizens, is a special camera equipment developed by the China Media Group after five years of research and development, which is specially used for broadcasting speed skating events of the Winter Olympics.The system consists of a gyroscope rail car and a 360-meter-long U-shaped track, with a cheetah-like speed, ccTV.com reported.In winter Olympics speed skating, athletes can reach speeds of 15 to 18 meters per second, or about 50 kilometers per hour. Top athletes can reach speeds of 70 kilometers per hour.The cheetah is designed to reach a speed of 25 meters per second, which is equivalent to 90 kilometers per hour.At the same time, because of its 4K high-definition capture technology, even the micro expressions of players can be clearly captured.Not only that, it can also achieve acceleration, deceleration and overtaking actions according to the needs of the live broadcast, so as to more flexible and random capture of the various scenes in the speed skating competition.At the Meet me In Beijing test event in March 2021, the cheetah made an impressive debut as it followed the sprinting runners around the 400-meter track, making every move impossible to miss.But the cheetah that netizens are talking about is actually located in the “Ice Ribbon” China National Speed Skating Hall, a speed skating competition venue.That night’s game was held at the Capital Stadium, which did not feature cheetahs.In the Capital Stadium, 40 4K camera arrays and 3 8KVR cameras are deployed, and the images captured by these lenses will be used for “interactive multi-dimensional viewing experience technology and system of ice and snow Projects”.Once the game starts, the 4K cameras will start working in sync.Due to the software control, multiple cameras can realize the synchronization of shooting parameters, ultra-fast focus, accurate capture of the details of athletes’ movements and other functions in a very short time, realizing the true sense of “see where you point”.The video footage shot by high-definition cameras is first transmitted to the image processing engine and processed by the chip to form multi-dimensional video data, which is then transmitted to TV /PC/ mobile phone and other user terminals by making full use of the “low delay and high throughput” capabilities of 5G network.In this way, viewers can not only enjoy the “bullet time” surround shot, but also choose the viewing Angle, zoom in and out, as their own “guide.”But neither the cheetah nor the camera array served only as live television footage, and the content of the footage was not used in the ruling.Zhao Wei, head of the special equipment department of the second broadcasting Department of the technology bureau of China Central Television (CCTV), clarified that the independent arbitration camera system used in short-track speed skating is different from special equipment such as cheetah, reported the website of the CENTRAL Commission for Discipline Inspection and the National Supervisory Commission Thursday.He said, the arbitration of camera system involve many cameras, video recording and slow-motion replay system precision by a fixed camera filming, recording every athlete or every lap game information, can be in slow motion mode and detailed analysis of athlete’s every movement, short track speed skating last night two decisions is based on the video system.Source: Ruan Jiaqi
