Bouncing, soaring, spinning, and stable landing... The gymnastics vault event at the Paris Olympics is a perfect combination of technique and strength. From takeoff to landing, the athlete's display time is only about 3 seconds, and all movements must be completed in one go, instantly determining the world. However, the momentary beauty often makes TV viewers feel 'unsatisfied'. How to enhance the viewing experience and allow TV viewers to see every key detail in a coherent set of athletes' movements? The 'time slicing' technology presents frames in every 3 seconds. The "time slicing" technique is similar to the multiple exposure technique of a camera, slicing the movements of athletes at different time points into images, flexibly capturing each frame of the action picture, and forming a "gathering" of exciting movements in the same background. Chen Xin, the person in charge of the cloud production platform of China Central Radio and Television Station, said that the "time slicing" technology is a new perspective provided by the station for the production of public signals. During the 2022 Winter Olympics in Beijing, the "time slicing" technology was used as a "small test" in the broadcast of ski jumping events. During the 2024 Paris Olympics, this technology will further mature, especially in athlete contour recognition and information extraction. The "time slicing" technology has made a qualitative leap, and the presented background has changed from a blurred background to a real-life environment, with clearer details of athletes' movements. At present, in addition to gymnastics, the "time slicing" technique has also been fully applied in the broadcasting of events such as diving and table tennis at the Paris Olympics. On July 31st Beijing time, during the broadcast of the event where Quan Hongchan and Chen Yuxi won the gold medal in the women's synchronized 10 meter platform diving for the Chinese delegation, it was with the help of "time slicing" technology that viewers could intuitively see through video playback that Quan Hongchan and Chen Yuxi seemed to have the "clone technique". From jumping to entering the water, the aerial trajectory composed of multiple body postures was frozen in the same picture, and the "water spray disappearance technique" also had a different way of presentation.
