BEIJING, Jan. 8 (Xinhua) -- More than 70 technological achievements will be applied during the Beijing 2022 Winter Olympic and Paralympic Winter Games (hereinafter referred to as the "Beijing Winter Olympics"), and new technologies such as artificial intelligence, high-definition display, and virtual reality will help improve the viewing experience in scenarios such as event reporting, event broadcasting, and live navigation. At that time, whether they are in the Winter Olympic venues or not, the audience will be able to get a high-quality viewing experience.
Inside the venue: Smarter event services
The Beijing Winter Olympics event service will reach more groups through advanced technology. The sign language broadcast digital people who will be put into use are specially designed for the hearing impaired, and can provide the whole process of intelligent digital human sign language generation services, which is convenient for the hearing impaired to watch the special report of the event.
In order to improve the accuracy of the Winter Olympic broadcast, the digital people also "mastered" the Winter Olympic sign language corpus, which includes multi-modal body movements, expressions, fingers and other corpora, which is convenient for hearing-impaired people to understand the progress of the event in real time.
Inside the venue, new technologies bring innovative guided tours to athletes, spectators and event staff, among others, safer and more intimate. It is understood that the Beijing Winter Olympics will apply the Winter Olympics virtual tour system based on three-dimensional space reconstruction technology, including the VR cloud experience platform for winter Olympic venues and the VR tour service platform for arrival and departure, to achieve functions such as scene display, facility description, activity promotion, and online VR self-service tour service.

In front of screen: The sensory experience is more fulfilling
What is so special about the "on the clouds" at the Beijing Winter Olympics? How does the new technology make the audience in front of the screen feel "immersive"?
On the 7th, the reporter saw at the TELEVISION program production center of the 8K Ultra-high-definition Experimental Channel of the Winter Olympics documentary of Beijing Radio and Television Station that in the 8K documentary broadcast on the TV, the snowflakes falling on the birds were clearly recognizable, and the water surface was glowing with bright light.
He Wenlin, television program production center of Beijing Radio and Television Station, introduced that 8K ultra-high-definition technology is the latest achievement in the upgrading of radio and television technology. The screen resolution of the program being played is 7680×4320, which is 4 times that of 4K and 16 times that of HIGH-definition, which can make the TV picture more brilliant and wide, the light and shade effects clearer and richer, and the details more beautiful and delicate.
On December 31, 2021, the country's first TV channel that provides 8K services to a wide audience, the Beijing Radio and Television Station Winter Olympics Documentary 8K Ultra HD Test Channel, was launched. At the same time as the visual effects have been improved, the program audio broadcast by the 8K channel has also been "upgraded". When the 8K graphics are combined with 5.1 multi-channel surround sound, the actual situation will be more realistic and shocking, and the scene will be more immersive.
The 5.1 channel allows the event to be broadcast "into the hearts of the people". It is understood that the 5.1 multi-channel surround sound applied by the 8K channel increases the environmental information and low-frequency information compared with the traditional stereo sound, which makes the finished audio product after production closer to perfection, and also makes the listener's perception of each sound source more clear and vivid.
Mobile: Video interaction is more diverse
The beijing winter olympic games will not only be transmitted to thousands of households through television, but also mobile devices can enjoy the wonderful moments of the 8K ultra-high-definition winter Olympic games.
Ou Xiaoxiao, information network management center of Beijing Radio and Television Station, introduced that the newly developed 5G high-tech video mobile application "8K APP" is expected to be launched this month. After going online, it is synchronized with the 8K channel and can watch the live broadcast of the Winter Olympic Games. She said that the biggest highlight of the APP is that the video can be enlarged during playback, so that the audience does not miss every detail.
Next to the 5G high-tech video station, Ou Xiaoxiao demonstrated to reporters the new gameplay of the 8K APP: by dragging and dropping, the video screen is enlarged from 20% to 200%, and the grass and trees in the classical garden in the picture are fully seen.
In response to the problem of device requirements, she said that 5G mobile phones above the middle and low end on the market can access and browse the APP, and can basically achieve smooth video playback without catatonic.
"We hope that users can participate more, and after the launch, we will continue to introduce high-quality resources such as VR video, panoramic video, and H5 interactive mini-games to meet people's curiosity when using it," Ou Xiaoxiao said. (End)
