On the evening of September 23, the opening ceremony of the 19th Asian Games in Hangzhou came to an end, with digital torchbearers, opening ceremony AR, interactive 3D TwinWire, etc. becoming the biggest highlights. At the opening ceremony,Over 100 million digital torchbearers ran out of the Alipay App to gather on the Lotus to light the main torch, achieving the world's first digital ignition ceremony.
"Digital people participate in the ignition, which is the first of its kind in the world. Tens of millions of torchbearers are a flame, a spark point, which converge over the Qiantang River to form a digital person." said Sha Xiaolan, chief director and chief producer of the opening ceremony of the Hangzhou Asian Games.
"Of course, the lighting of the flames includes not only the live audience, but also audiences across the country, Asia and even the world. When the torch is lit, I believe those participating audiences will be more excited than us. Because this idea allows more people to participate." Cui Wei, deputy director of the opening ceremony, said.
After the lighting ceremony, each digital torchbearer can receive a digital lighting certificate, engraved with the unique image of each digital torchbearer. This certificate is stored on the blockchain through distributed technology and can forever remember the glorious moment of lighting the torch. At the same time, the Hangzhou Asian Games also simultaneously released the first "Digital Main Torch Tower" in history through the Alipay App. Relying on physical restoration design and three-dimensional rendering technology, it is the first Asian Games digital licensed product that can be upgraded and deformed.
In addition to the exciting lighting ceremony, the AR interaction at the opening ceremony also impressed the audience. By opening Alipay and scanning the main stage, you can summon the mascot "Three Little Ones" on the spot, release wishing lanterns, and send postcards... The technological integration of AR (Augmented Reality) and AI (Artificial Intelligence) is refreshing.
It is reported that the technical team sent a team of nearly 30 people to collect 10-20 seconds of data at different angles and in different ways in the 3-story Grand Lotus Grandstand, 24 areas, and 216 points. A total of more than 400,000 frames of image data were collected. All picture data are trained by AI algorithms, and the recognition success rate exceeds 95%, ensuring that even viewers sitting in the corner can participate in the dark light environment.
"We hope that tens of thousands of spectators can participate in the opening ceremony and become part of the live performance." Chief Director Sha Xiaolan said, "This is also a manifestation of the smart Asian Games, using the power of technological innovation to create classic memories of the Asian Games."
Sha Xiaolan also introduced,For the first time, the team applied dual 3D wire technology to the air in a large sports stadium. The three-dimensional male and female actors flying in the air interact with the waves on the ground in real time., “This is a two-way journey between people, grassland, and beauty.”
At present, the application of artificial intelligence in sports, especially competitive sports, is becoming more and more widespread. A "technological storm" in competitive sports has swept across.
A reporter from the "Science and Technology Innovation Board Daily" learned that Lenovo provided AI-embedded smart terminals for the Asian Games, including more than 10,000 computers and other equipment, including 6,000 Lenovo Zhaoyang commercial notebooks, more than 3,000 Lenovo ThinkCentreM master series commercial desktops, and more than 160 sets of Lenovo Savior consoles and professional e-sports monitors and other terminals.
The first two are distributed in 6 major competition areas and 74 competition and non-competition venues, fully supporting the daily office and event operation tasks of 18 teams including the Asian Games General Headquarters, Competition Information Inquiry Center, Athlete Registration Center, and Media Center. The latter serves as the official designated e-sports computer for the Hangzhou Asian Games, providing high-performance configuration support for e-sports.
Off the field, it helps the Zhejiang Meteorological Bureau build a comprehensive meteorological computing resource platform that includes physical and virtual computing resource pools, storage resource pools and meteorological big data resource pools to provide accurate weather forecasts and "escort" each event.
Ye Jianhua, vice president of Danghong Technology and general manager of the Media and Culture Business Department, told a reporter from the Science and Technology Innovation Board Daily,The Hangzhou Asian Games is the first time in the history of Asian Games broadcasting to provide viewers with the ultimate audio-visual experience by applying my country's independent intellectual property rights "8KAVS3+Dual Vivid" ultra-high definition technology..
"The resolution of 8K is 16 times that of 1080P, which can bring richer details and a more shocking visual experience to the audience. During this Asian Games, Danghong Technology supports China Central Radio and Television, China Mobile Migu Company, Douyin, Tencent Video and other rights-holding broadcasters to apply my country's audio and video standards (AVS3, HDRVivid, AudioVivid) with independent intellectual property rights."
Among them, AVS3 is the world’s first video and audio source coding standard for 8K and 5G industrial applications. Dual Vivid refers to HDRVivid (Essential HDR) and AudioVivid (Three-Dimensional Sound), which are HDR standards and three-dimensional sound standards with independent intellectual property rights in my country, allowing 8K videos to have better light and dark details and an immersive sound experience.
E-sports has become an official competition event for the first time in this Asian Games. Many listed companies such as Jinling Sports, Shuhua Sports, and Dianhun Network are involved in Asian Games-related businesses. Ye Jianhua said that Danghong Technology provides technical support for e-sports live broadcasts through AI coding technology based on the subjective vision of the human eye.
"The live broadcast of e-sports events has the characteristics of complex scenes and rapid changes; game players have demands for ultra-low latency, delicate images, silky smoothness, etc. for e-sports videos. We provide broadcasters with rights to provide high frame rates of 50/60fps, low latency within 50ms, and support for dozens of concurrent live broadcasts on a single server. At the same time,Based on technical research and algorithm optimization of e-sports video, AI coding technology based on human subjective vision is added, to further improve the image quality of parts sensitive to the human eye. In addition, it can also provide 4K/8KHDR (high dynamic range) and VR/AR technology processing capabilities across the entire link, making the picture as close to the real world as possible. "
