In addition, more than 50 companies are involved in various types of security services. Among the listed companies on the Science and Technology Innovation Board, Kingsoft Office is the official collaborative office software supplier of the Beijing Winter Olympic Games, Qianxin is the official sponsor of the network security services and anti-virus software of the Winter Olympic Games, and Danghong Technology provides technical support for the ultra-high-definition video broadcast of the Winter Olympic Games.

Li Zhi, an expert at the Whale Platform think tank and president of the Analysys Wisdom Institute, told the "Science and Technology Innovation Board Daily" reporter that the Winter Olympics is mainly a comprehensive application display of various digital technologies, not only to present advanced digital technologies, but to show the positive effects of digital technologies on users, the development of the industry and urban governance, and this application demonstration will also catalyze the accelerated development of digitalization of some industries and tracks.

Wang Yingbo, an expert at the Whale Platform think tank and a doctor of economics at the Shanghai Academy of Social Sciences, also said that a major feature of the Winter Olympics is comprehensive digitalization, which is a stage of development of the digital economy towards the metacosm.

The first cloud-on-cloud Olympics and 8K Ultra HD live streaming

It is understood that for the first time in the history of the Olympic Games, the core system has been fully clouded, and will broadcast 6,000 hours of content through the cloud to billions of viewers around the world, so that the Olympic broadcast no longer relies solely on satellite transmission. At the same time, for the first time, 8K ultra-high-definition live broadcast technology will be used to bring a better viewing experience to the audience in front of the TV.

Wang Yingbo pointed out that this is the first cloud Olympic Games, will be broadcast live on Alibaba Cloud, 8K ultra-high-definition live broadcast will bring the audience immersive experience and more abundant, real-time interactive mode, although now due to the bottleneck of computing power and network speed, it is not yet possible to achieve holographic imaging and deep immersion effects, but compared to the past has been a very big leap.

In terms of viewing experience, on the basis of the cloud, the application of visual intelligence, algorithms, AR and other technologies in the arena allows the audience to be immersed in the scene. For example, through multi-angle intelligent synthesis technology, multi-array video is combined into a panoramic dynamic picture, which brings more dimensions of viewing perspectives for short track speed skating, curling and other competitions.

As one of the technical support parties for this 8K ultra-high-definition broadcast, Tan Ya, secretary of the board of directors of Danghong Technology, introduced to the "Science and Technology Innovation Board Daily" reporter that the amount of 8K ultra-high-definition video data is huge, and CCTV uses Danghong's 8K ultra-high-definition coding technology to compress the signal into a 120Mb code stream, greatly reducing the pressure of transmission bandwidth, ensuring efficient, smooth and safe content transmission and playback, and providing users with a more extreme visual experience.

For the development of 8K HD after the Winter Olympics, Tanya analyzed that large-scale sports events and broadcasting technology are mutual achievements. The development of satellite communications has made it possible to broadcast live globally, and billions of people can share the excitement of the Olympic Games. The development of optical fiber communications, 5G, and ultra-high-definition coding technology has made 8K ultra-high-definition live broadcasting a reality. Ultra-high-definition technology, first of all, is applied in the field of radio and television with the highest professional requirements, and the next step will be extended to the fields of culture, education and entertainment, medical health, and industrial manufacturing.

The combination of ultra-high definition and AR/VR brings more imagination space. Pan Helin, member of the Information and Communications Economic Expert Committee of the Ministry of Industry and Information Technology and executive dean of the Digital Economy Research Institute of Zhongnan University of Economics and Law, said, "With the improvement of the living standards of the Chinese people, the demand for high-definition TVs has increased, and the supporting high-definition live broadcast and high-speed 5G communication have greatly improved the live broadcast experience of the living room. In the future, VR/AR will break the regional restrictions of the Winter Olympics, such as simulating the sports experience at home through somatosensory devices and VR. ”

Li Zhi believes that for users, "5G+8K" and through cloud broadcasting and other ways, can present ultra-high-definition game screens, at the same time, the application of VR in live broadcasting of events will give the audience a more shocking viewing experience, which is an important expansion of ultra-high-definition and VR scenes.

IPv6+ technology is making its first appearance at the Olympics

The "Science and Technology Innovation Board Daily" reporter learned that in terms of communication networks, this Winter Olympics is the first time that IPv6+ technology has been applied in large-scale events.

According to Yang Lifan, deputy general manager of Beijing Unicom, a number of key technologies of IPv6+ are necessary to build a smart Winter Olympics private network. The communication network of the Winter Olympics needs to cover more than 80 venues in three competition areas of Beijing and Zhangjiakou City, Hebei Province, as well as high-speed and high-speed rail transportation lines between Beijing and Zhangjiakou, and serve more than 2,600 international mainstream media staff, more than 30,000 Olympic family members and many well-known broadcasters to meet the high-quality unlimited speed access needs of more than 150,000 terminals.

IPv6+ routing technology and intelligent SDN network controller provide low latency path selection, latency degradation perception and latency tuning capabilities. "At the time of the front-line net test, the entire delay indicator was far better than the requirements put forward by the Olympic Organizing Committee." Yang Lifan revealed.

At the same time, the smart Winter Olympics private network is based on IPv6+'s network programming capabilities, with strong service rapid provisioning capabilities and flexible service adjustment capabilities. "We all know that in major events, one of the most headaches encountered in the past was the emergency opening and frequent adjustment of the private line service, which can now provide media customers with rapid opening services."

In addition, by introducing IPv6+ current detection, AI-assisted O&M, and protection reversal technology that can cover 100% of all links, it can realize the active perception of service quality difference at the granularity of the minute level, realize the minute-level artificial intelligence assisted fault handling, and protect the reverse in any fault scenario for 50 milliseconds.

Accelerate the development of the digital economy

In Pan and Lin's view, the digital innovation of the Winter Olympics is reflected in all aspects. First of all, the current athlete training relies more on digital technology, statistics on data, the formation of targeted training programs, more scientific and more efficient; followed by the Winter Olympics broadcast technology, higher purity, better results; and then the Winter Olympics payment field, digital yuan and various scenarios integration, to create a new digital scene; and finally better bandwidth, more high-quality communication experience.

Li Zhi believes that the Winter Olympics will bring benefits to green energy vehicles, especially hydrogen energy vehicles, and will further accelerate penetration. At the same time, the Intelligent Vehicle Networking System based on the 5G network and Beidou high-precision positioning built by the Winter Olympics is a large-scale application of L4-level automatic driving. It also has a role in promoting intelligent medical treatment, on the one hand, it is the monitoring and analysis of real-time data on athletes' physical signs, on the other hand, it is the analysis of epidemic prevention data and emergency treatment.

In terms of urban governance, Li Zhi pointed out that the Winter Olympics will enable the digital twin system, fully digitize and model the stadiums and surrounding areas, gain real-time insight into the operation of venues, meteorological changes and the current situation of urban transportation operations, and give full play to the management, guarantee and optimization value of urban governance.

Wang Yingbo told the Science and Technology Innovation Board Daily that more digitization processes of the Winter Olympics are hidden behind the scenes, such as digital modeling to reduce the error rate of communication equipment installation, and the overall operation is gradually moving towards automation and digitization.

"It is believed that this Winter Olympics will promote the further digital transformation of the overall economy and accelerate the development of China's digital economy." Wang Yingbo said.
