the first cloud Olympics and 8K UHD live broadcast
It is understood that the Winter Olympic Games has realized the full cloud of the core system for the first time in the history of the Olympic Games, and will broadcast 6000 hours of content to billions of viewers around the world through the cloud, so that the Olympic Broadcasting will no longer rely solely on satellite transmission. At the same time, 8K UHD live broadcast technology will be used for the first time to bring a better viewing experience to the audience in front of the TV.
Wang Yingbo pointed out that this is the first Olympic Games on cloud. The Games will be broadcast live on Alibaba cloud. The 8K ultra-high definition live broadcast will bring the audience an immersive experience and a richer and more real-time way of interaction. Although it is still unable to achieve the effect of holographic image and deep immersion due to the bottleneck of computing power and network speed, it is a very big leap compared with the past.
In terms of viewing experience, on the basis of cloud, the application of visual intelligence, algorithm, AR and other technologies in the field allows the audience to be immersive. For example, through the multi angle intelligent synthesis technology, the 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 guarantors of this 8K UHD broadcast, Hangzhou Arcvideo Technology Co.Ltd(688039) Board Secretary Tan Ya introduced to the reporter of science and Innovation Board daily that 8K UHD video data is huge. CCTV adopts danghong's 8K UHD coding technology to compress the signal into 120MB code stream, greatly reducing the pressure of transmission bandwidth and ensuring efficient, smooth and safe content transmission and playback, Provide users with 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 broadcasts around the world, and billions of people can share the highlights of the Olympic Games. The development of optical fiber communication, 5g and UHD coding technology has made 8K UHD live broadcast a reality. Ultra high definition technology is first 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 and health, industrial manufacturing and so on.
The combination of Ultra HD and AR / VR brings more imagination space. Pan Helin, member of the information and communication economy expert committee of the Ministry of industry and information technology and executive director of the Digital Economy Research Institute of Zhongnan University of economics and law, said, "With the improvement of China's Lbx Pharmacy Chain Joint Stock Company(603883) living standards, the demand for high-definition TV increases, and the supporting high-definition live broadcasting and high-speed 5g communication greatly improve the live broadcasting experience of the East Olympic Games in the living room. In the future, VR / AR will break the regional restrictions of the Winter Olympic Games. For example, you can simulate the sports experience at home through somatosensory devices and VR."
Li Zhi believes that for users, "5g + 8K" and through cloud broadcasting can present ultra-high definition game pictures. At the same time, the application of VR in the live broadcast of events will give viewers a more shocking viewing experience, which is an important expansion of ultra-high definition and VR scenes.
IPv6 + technology appears in the Olympic Games for the first time
The reporter of "science and Innovation Board daily" learned that in terms of communication network, this winter Olympics is the first application of IPv6 + technology 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 Olympic private network. The special communication network for the Winter Olympics needs to cover more than 80 venues in the three competition areas of Beijing and Zhangjiakou, Hebei Province, as well as the high-speed, high-speed rail and other transportation lines between Beijing and Zhangjiakou. It needs to serve more than 2600 staff of international mainstream media, more than 30000 members of the Olympic family and many well-known broadcasters, so as to meet the high-quality and unlimited access needs of more than 150000 terminals.
IPv6 + routing technology and intelligent SDN network controller provide low delay routing, delay degradation perception and delay tuning capabilities. "When testing the frontline network, the whole delay index is far better than the requirements put forward by the Olympic Organizing Committee." Yang Lifan revealed.
At the same time, the intelligent Winter Olympics private network has the network programming ability based on IPv6 +, and has the strong ability of fast service opening and flexible service adjustment. "We all know that one of the biggest headaches in major events in the past was the emergency opening and frequent adjustment of special line services. Now we can provide fast opening services for media customers."
In addition, by introducing IPv6 + streaming detection, AI assisted operation and maintenance and protection switching technology that can cover 100% of all links, we can realize the active perception of poor service quality with minute granularity; Realize minute level artificial intelligence assisted fault handling, and 50 millisecond protection switching in any fault scenario.
accelerate the development of digital economy
In Pan Helin'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 to make statistics on the data and form a targeted training scheme, which is more scientific and efficient; The second is the broadcasting technology of the Winter Olympic Games, which is higher definition and better effect; Furthermore, in the payment field of the Winter Olympic Games, digital RMB is integrated with various scenes to create a new digital scene; Finally, better bandwidth and better communication experience.
Li Zhi believes that the Winter Olympics will bring benefits to green energy vehicles, especially hydrogen energy vehicles, and will further accelerate the penetration. At the same time, the intelligent vehicle networking system based on 5g network and Beidou high-precision positioning built by the Winter Olympics is a large-scale application of L4 level automatic driving. It can also promote intelligent medical treatment. On the one hand, it is to monitor and analyze the real-time data of athletes' signs, on the other hand, it is to analyze the 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, comprehensively digitize and model the stadiums and surrounding areas, have real-time insight into the venue operation, meteorological changes and the current situation of urban traffic operation, and give full play to the management, guarantee and optimization value of urban governance.
Wang Yingbo told the science and Innovation Board daily that more digital processes of the Winter Olympics are hidden behind the scenes, such as digital modeling, reducing the error rate of communication equipment installation, and the overall operation is gradually moving towards automation and digitization.
"I believe 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.
