Ahead of the Opening ceremony, the International Olympic Committee (IOC) publicly announced that the Beijing Winter Olympics would be broadcast entirely in 4K ultra HD format, reaching billions of viewers around the world through an Olympic broadcast cloud backed by Chinese tech company Ali Cloud.What are the advantages of “cloud broadcasting” technology over traditional broadcasting?What benefits can the Beijing Winter Olympics bring to global participants?The reporter recently interviewed the head of ali Cloud Olympic project, the key supporting technology of “Cloud on the Olympic Games” was revealed.Alibaba Cloud data center, located in Zhangbei County, Hebei Province, is the key data center for the Beijing Winter Olympics, which opened on February 4, becoming the first full cloud Olympic Games in history.It is understood that the Beijing Olympics is not only the global event broadcast on the cloud, and completed the core system historic project of 100% on cloud, will the results, the broadcast of the event, information release, athletes, all the information such as location, room and board, transportation system migration on the cloud, unified portal, application integration and data integration.Under the challenge of the global epidemic, the cloud broadcasting technology enables the massive high-definition images of the Beijing Winter Olympics to go global with the help of the “cloud” end.The cloud-based broadcast technology used for this year’s Games is cheaper and more flexible than traditional satellite broadcasts.In traditional broadcasting, the rights-holding TV stations of each country need to go to the competition country to report, transport 15 tons or more of broadcasting vehicles and editing equipment across the sea, and send a large number of technical transport and editing staff together with the reporters to the Olympic Site.”The layman’s idea is that with cloud broadcasting, a lot of broadcasting equipment that used to need to be transported to the field can be moved to the cloud.”Ali Cloud Olympic project director Zhang Dazhi said.With the support of the broadcast cloud, many equipment can be moved to the cloud without having to be transported, and technical and editorial staff can also work remotely, even if no one goes to the site, the Olympics can be completed.It is worth noting that the performance of cloud broadcasting is better than that of satellite broadcasting. Under normal circumstances, the bandwidth of cloud broadcasting is one order of magnitude higher than that of satellite broadcasting, and in extreme cases, it can even be expanded to TB level, equivalent to transmitting 500 HD movies in one second.Zhang Dazhi believes that with the increasing content of the Olympic Games broadcast, it can be foreseen that its content may exceed the limit of satellite transmission in the future, and cloud broadcast will become an inevitable trend.”The data we have from OBS, the Olympic Broadcasting Service, is that OBS plans to produce 6,000 hours of HD 4K programming during this year’s Winter Games, a 50 percent increase over the last Winter Games.”With cloud coverage, broadcasters have 40 percent fewer staff and 30 percent fewer latency across the network.”Zhang Dazhi said.Green and low-carbon are also important features of this year’s Winter Olympics.Ali cloud has said, ali provide the data support for the Beijing Olympics center a large number of used the clean energy such as wind, solar, and adopted the latest artificial intelligence technology to reduce the energy consumption, make the data center energy consumption dropped 70% than traditional data center, can save 80000 tons of coal a year, equivalent to planted more than 400 trees per year.In January 2017, a team of Aliyun engineers from China went to the INTERNATIONAL Olympic Committee headquarters in Lausanne, Switzerland for negotiations. At the scene, the cloud technology team, which had carried the traffic peak of “Double 11”, deployed a cloud-based broadcast environment in only 10 minutes, which impressed the IOC.In the same year, Ali Cloud was selected by the International Olympic Committee as the only cloud service provider for the Global Olympic Games, which started the journey of cloud service together with the Olympic Games.In 2018, The “Olympic Broadcast Cloud”, jointly developed by AliYun and Olympic Broadcasting Services, made its debut and was used for the first time at the Tokyo Olympics in 2021, supporting 9,500 hours of event content broadcast.In the Beijing Winter Olympic Games, retransmission cloud once again ushered in a major upgrade, for the global TV, network media to provide high-definition live events signal.
