Source Title: A batch of new technology applications can watch the 8K game screen during the Beijing Winter Olympics
China News Service, Beijing, November 18 (Reporter Chen Hang) During the Beijing Winter Olympics, audiences can watch the 8K game screens on TV, and can also watch the super on 8K terminals in the Winter Olympics venues, city squares and other places. High-definition picture.
This is what the reporter learned from the Science and Technology Winter Olympics press conference held by the Beijing Winter Olympics Organizing Committee on the 18th.
Technology is an indispensable support for the Beijing 2022 Winter Olympics and Paralympics. On the basis of traditional Olympic technical services, there will be new technical applications in every Olympic event.
Yu Hong, director of the Technology Department of the Beijing Winter Olympics Organizing Committee, said that the Beijing Winter Olympics Organizing Committee focuses on new technology needs in infrastructure, green environmental protection, smart services, broadcast technology, artificial intelligence and other aspects. A batch of new technology achievements have been tested this year. Application in competitions and testing activities.
As the iconic venue of the Beijing competition area of the Beijing Winter Olympics, the National Speed Skating Stadium adopts the world’s largest single-layer two-way orthogonal saddle-shaped cable net roof, which uses only one-fourth of the traditional roof; it is called “Snow You Dragon” The national snowmobile sled center adopts “millimeter-level” hyperboloid concrete spraying and finishing molding technology, and the 1.9-kilometer race track is sprayed and poured at one time.
“The Internet of Things and artificial intelligence technologies are building the Bird’s Nest into a digital, low-carbon, and smart stadium.” Yu Hong said that 5G signals cover all Winter Olympic venues and roads connecting the venues, providing ultra-high-definition video, various intelligent services, etc. The application scenario provides the necessary network connection.
Broadcasting is indispensable in the modern Olympics, allowing Olympic fans all over the world to feel the wonderful performance of athletes no matter where they are.
“Because of the 5G signal coverage, there is a new mode of broadcasting.” Yu Hong said that the cloud broadcasting 5G backpack can realize high-definition video instant transmission; weather data will also be transmitted in real time through the 5G communication system.
Outdoor events such as alpine skiing, ski jumping, and aerials at the Beijing Winter Olympics require very accurate weather forecasts. The weather conditions determine whether certain events start on time or need to be delayed.
Yu Hong said that the Winter Olympics weather forecasting system can achieve “hundred-meter-level, minute-level” precise weather forecasts. In the test event in February this year, the Beijing Winter Olympics Organizing Committee adjusted the schedule of 12 games and training based on weather forecasts.
In order to achieve the carbon neutral goal of the Beijing Winter Olympics, the Zhangbei Flexible DC Grid Project will import green electricity produced by wind and solar energy in the Zhangbei area into Beijing, and all venues will achieve 100% green power supply during the Beijing Winter Olympics.
At the same time, the National Speed Skating Stadium, Wukesong Sports Center and other Winter Olympic venues use carbon dioxide transcritical refrigeration systems, the temperature difference of the ice surface is controlled within 0.5 ℃, and the carbon emissions are close to zero. And the cooling waste heat is recycled, and the energy efficiency is increased by 30% to 40%.
Yu Hong said that all the relay torches in the Beijing Winter Olympics will use hydrogen fuel; 80 hydrogen fuel cell vehicles have been tested in the Zhangjiakou competition area of the Beijing Winter Olympics, and more than 700 hydrogen fuel cell vehicles will be put into the Yanqing and Zhangjiakou competition areas during the competition. Fuel buses provide transportation service guarantee.
In the application of new technology, the audience will also experience a different way of watching the game.
Yu Hong said that the free-view technology allows the audience to freely choose the viewing angle and time on the screen; the stadium panoramic picture guide can browse the stadium online; the indoor accurate navigation helps the audience quickly reach the stadium seating area.
In addition, during the Beijing Winter Olympics, spectators have the opportunity to see 8K game images on TV, and also have the opportunity to see ultra-high-definition images on 8K terminals in Winter Olympic venues, city squares and other places.
“Today is 79 days from the opening of the Beijing Winter Olympics.” Yu Hong said that he expects athletes to have a wonderful performance in the competition, and also expects that these technical achievements can provide better match-time services to the Beijing Winter Olympics customer groups.
