[Explanation] On November 8, the "Meet in Beijing" ice hockey domestic test event kicked off at the Wukesong Sports Center.
Due to epidemic prevention and control reasons, this test match is not open to spectators.
In order to allow the audience to truly experience the fun of the ice and snow project outside the stadium, the event has a number of innovations in the TV broadcast technology.
In the inner ring corridor of the competition venue, 60 cameras are hoisted 180 degrees below the ring screen in the hall, plus three spherical cameras in the middle of the seats. This multi-dimensional game viewing experience and VR live broadcast technology bring more to the audience. Yuan's game watching experience.

With the development of 5G and the Internet, it can now be used to watch games in multiple dimensions. What is the concept?
It is through the mobile phone or the large screen, the audience can freely choose your perspective.
If we are (providing) a 180-degree free viewing, you can watch it at 180 degrees; if it is a 360-degree free viewing angle, you can watch it in 360 degrees.
So it realizes a kind of interactive (match broadcast), so everyone's broadcast experience will be better.
[Explanation] According to Li Xufeng, a technician at Peking University, in the 5G and Internet environment, viewers can use mobile phones, VR helmets and large TV screens to achieve free viewing angles and VR live viewing.
This method breaks through the limitations of traditional fixed viewing angles and passive game viewing, allowing the audience to experience an autonomous and interactive way of watching the game.

One is VR (viewing angle).
Everyone knows that the definition of VR has generally been improved to 8K, but this 8K transmission is very bandwidth-consuming, and at least 60 megabytes of bandwidth is required for transmission.
But we use a new technology based on a main perspective (technology), that is, we can transmit whatever we see, to reduce the bandwidth to 10 megabytes or even lower bandwidth, so that everyone can see the past through 10 megabytes of bandwidth. An effect of 60 trillion.
[Explanation] This broadcast technology is a key project of the national key research and development plan "Science and Technology Winter Olympics", which is led by Peking University to specifically research and develop the characteristics of the ice and snow sports in the Beijing Winter Olympics.

In fact, this technology is still in the experimental stage and there is no large-scale commercial use, but it has already been used in some competitions. For example, in our CBA competitions and in the just-concluded National Games competitions, we have already begun to use this technology. Technology.
The future development is that traditional live broadcast is definitely not a substitute, so the organic integration of the two will greatly enhance the audience's watching experience.
[Explanation] It is reported that in the "Meet in Beijing" Winter Olympics series of test activities in April, the results of the project debuted at the Winter Olympics venues.
During the Winter Olympics, it may be widely applied to the broadcast of multiple events.
