1 . The 19th Asian Games are about to kick off, opening on Sept 23 in Hangzhou. Held in a city famous for its digital technology, the Games have the principle of “being smart”.
With the rise of high-definition livestreaming(高清直播), sports venues(场馆) have placed higher demands on internet connections. In the Hangzhou venues, 5G-Advanced, or 5.5G technology, will be applied. Zhang Jian from China Telecom told Economic Information Daily: “The technology of 5.5G can support the high-definition livestreaming of about 10 events at the same time.”
A strong signal for a smooth livestreaming experience and fast Internet speed for audiences during the events will be achieved through the use of Reconfigurable Intelligent metaSurface (RIS) technology. It looks like a white-colored board, and is roughly the size of a TV. RIS can effectively reflect signals covering up to 10,000 square meters with no internet dead spots.
Online viewers will also get to enjoy some smart technology. Take the badminton competition venue as an example. On the second floor of the stadium, there are 20 high-definition cameras. A virtual reality (VR) camera is also positioned at the net, capturing(捕捉) athletes’ movements from different angles. Backstage staff can create slow-motion videos 5 to 10 seconds after the move, reported the IT Times.
Viewers wearing VR glasses can see what’s happening within the stadium remotely. They can “move around” in the virtual scene and even stand beside the athletes to cheer them on. When watching the Games on their smartphone, viewers can choose from four perspectives, including a bird’s eye view or a close-up view of an athlete.
Viewers can also get a quick tour of the venues in the metaverse(元宇宙). By clicking into a mini program on Alipay, users can enter the metaverse, where Asian Games venues and maps are re-created in an animated(动画的) style. Each user can have their own digital character. Users can “take a walk” in different venues and chat with other users. They can also play mini-games with other users, such as playing with different competitors in a running contest.
