Without being able to visit the scene in person, audiences around the world watched the Olympics in the “cloud” mode for the first time. How to ensure the liveliness and liveliness of the event and shorten the distance between the audience and the stadium? This is the biggest problem facing the broadcast team.

On July 22, IOC President Bach said that for the first time this year, the Olympic Games will adopt the technology of Chinese technology company Alibaba Cloud to support global broadcasting. This is an important step for the Olympics to enter the digital age. “OBS Cloud, jointly created by Alibaba Cloud and Olympic Broadcasting Service (OBS), was put into use at this Olympic Games to provide support to authorized broadcasters around the world.” Alibaba Cloud technical expert Wan Yiping introduced that this is the first time cloud computing has supported the Olympic Games.

At the same time, OBS will also produce Olympic content in Ultra High Definition (UHD) and High Range Dynamic (HDR) for the first time, which can provide four times more details than standard HD formats. In addition, OBS Cloud also provides 3D athlete tracking technology. For example, in the track and field sprint event, the audience can see the real-time running speed of each athlete with near-real-time insight and superimposed visualization to enhance the viewing experience.

Zhang Jianfeng, President of Alibaba Cloud Intelligence, said that for this special Olympics, digitalization is not only a challenge, but also an opportunity. For global audiences, it is the first time to watch the Olympics in the “cloud” mode; for global media, based on OBS Cloud, broadcasters do not have to go to the Tokyo Olympics site in person, and can complete the broadcast and editing work remotely.

With OBS Cloud, the cost of Olympic broadcasting is greatly reduced. The area of ​​the international broadcasting center for the Tokyo Olympics can be reduced by 25%, and on-site staff reduced by 27%. “OBS Cloud transfers a lot of hardware-based broadcast work to the cloud, which can make the work of broadcast media more effective and lower cost. This is a major innovation.” OBS CEO Ianis Exakos said.

In addition to the cloud watching games, there is also a strong Chinese power behind the TV broadcast of the Tokyo Olympics. In July, the 4K/8K ultra-high-definition broadcast vehicle of China Central Broadcasting and Television Headquarters crossed the ocean and appeared on the streets of Tokyo. A 316-member international public signal production team from the main station will undertake the five events of the Tokyo Olympics gymnastics, badminton, table tennis, rock climbing, and track and field shot put finals, and the Tokyo Paralympic Games track and field and goalball for the blind.

In the traditional competitive sports of table tennis, badminton, gymnastics and other traditional Chinese competitive sports, the main station signal production team has also reached the international top level.

Due to the impact of the epidemic, the signal production encountered special difficulties. “We must focus on key athletes and outstanding athletes while being fair and just, which increases the difficulty of production.” said Wang Ping, head of the public signal production team at the main station. When the personnel and equipment are not in place, the time left for the production team to prepare and run-in is greatly shortened. In addition, the empty game also requires corresponding adjustments in the deployment of the broadcast screen.

Faced with multiple difficulties, the Chinese production team strives to make up for it by various means. For example, new equipment was used in gymnastics, and the athletes’ shots in the warm-up area were added; in the rock climbing event that became an Olympic event for the first time, virtual reality technology was used in signal production…All efforts were made to present the most exciting live broadcast.
