What are the highlights of Beijing Winter Olympics?

The scientific and technological highlights of the Beijing Winter Olympics are:

1, the center of the Bird's Nest has an oversized 8K floor screen. The screen area is 10552 square meters, which consists of more than 40,000 LED modules, and an 8K LED screen with 1200 square meters is erected on it. Two screens constitute the world's largest ultra-high definition LED three-dimensional stage.

Screen-integrated intelligent broadcast control system presents ultra-high resolution video materials on all modules every second, which not only perfectly displays various image effects, but also integrates digital technology, artificial intelligence motion capture, virtual reality enhancement technology and so on, subverting the traditional stage performance mode.

2. The "Yang Fei" torch and the main torch platform, which inherit the Olympic flame, have made many innovations in design, hydrogen storage, hydrogen supply and combustion technology, showing the innovative practice of realizing the new concept of green and low carbon by high technology.

3. Virtual simulation technology was applied in the rehearsal of the opening ceremony, which realized the whole process, all elements and all-round visual simulation from the thermal field to the torch relay. The creative arrangement and modification of the director group can be simulated in the simulation environment, which improves the efficiency of arrangement and practice and greatly reduces the cost of on-site rehearsal.

4. In hosting sports events, "Science and Technology Winter Olympics" has solved the technical problems in the design, construction, operation and maintenance of snowmobile track, national ski jumping center, speed skating hall and other venues, and supported the renovation of venues such as "Bird's Nest" intellectualization and water cube ice water conversion.

5. The video service system (Info-AV) of Beijing Winter Olympics press conference provides live news, on-demand and download services for all press conferences during the Winter Olympics, and can independently select the audio output of original sound or simultaneous interpretation. The audio and video production, editing and processing of the conference are all done remotely in the cloud.
