"Athletes compete hard, and we are responsible for bringing their best moments to a global audience in the first place, cheering and cheering for them!" At this moment, Fang Guangyun, communication manager of China Unicom Genting Ski Park, is busy in the network equipment room of the stands. Colleagues at various duty points of the Unicom team were very excited at the moment they heard that Xu Mengtao won the championship, and felt that the efforts of day and night here had received the loudest affirmation.
However, the Unicom team will continue to bury their heads in work. "Fast" is an important need in the news coverage of the Winter Olympics. In order to pass on the wonderful events in the first place, every communication service link can not make any small mistakes. From the opening and acceptance and delivery of the broadcast service to the adjustment and testing of the "Media +" business point, China Unicom 5G Grand Connection fully guarantees the smooth flow of the event screen and news.
5G backhaul: Break through the shackles of wired transmission
In the past, the video playback technology of cable transmission was mainly used in the broadcast of events, and the cable transmission was limited by the length of the cable, which was difficult to bring an immersive feeling to the audience. In the broadcast of this event, in addition to ensuring the wired transmission channel, China Unicom also provides 5G backhaul technology, which can take advantage of high bandwidth, low latency and strong mobility to break through the shackles of traditional wired transmission.
Mountain broadcast center is the export of TV broadcast signal in Zhangjiakou area, China Unicom mountain broadcast center communication manager Zhao Juhui introduced, this Winter Olympic Games, in some tracks arranged high-speed mobile high-definition cameras, relying on 5G backhaul technology, the majority of viewers can follow the lens of the mobile camera, multi-angle, immersive viewing of the game.
"It's a great pleasure to see the clear and smooth footage of the TV and the wonderful performances of the athletes as a member of the Mountain Broadcasting Center – each wonderful shot carries the hard work and efforts of every communication support worker in our stadium day and night behind the scenes."
Media +: Instant shooting, instant transmission, instant launch
In addition to television broadcasting, the world's major news agencies can send out pictures and texts for the first time, which is inseparable from the "media +" service provided by China Unicom.
According to Ma Yaheng, communication manager of China Unicom Mountain News Center, the "Media +" service can realize automatic shooting cameras, shooting robot shooting content that is shot and transmitted, from the competition venue to the first time to transmit the mountain news center, to provide materials for the rear photography and text reporters, convenient for rapid editing, instant release.

The Winter Olympics of wisdom originate from the ingenuity of connecting people
On the basis of the successful service of the event, the scientific and technological content should also be full. As early as during the test match, China Unicom provided cloud broadcast and unmanned mixed interview guarantee services in Zhangjiakou, and the "5G + Beidou" precision distribution innovation business also appeared in "Xue Ruyi". At the Olympic Games of the first 5G application scale landing, with the blessing of China Unicom's 5G connection, the style of the Winter Olympics of Science and Technology and the Winter Olympics of Wisdom is also adding icing on the cake for a miracle moment. Behind it are the people who are rooted in this and struggling here.
"What was the first ray of sunlight that the Winter Olympics Unicom people saw? The sun shines on the mountain slope on the west side of the mountain, and the sun rises in the east shines there first", and every day to meet the first rays of sunlight, the Unicom team will embark on the road of inspection on time. They have to reach the various points at the allotted time. Outdoor minus 20 degrees, extremely windy, the guards stood for a while, the soles of their feet channeled cold wind, in the words of China Unicom Genting Ski Park communications manager Fang Guangyun, is "'physical damage' + 'magic damage' at the same time." Although they are frozen, it does not prevent them from doing a good job in every duty and doing their best for every game.
In the weeks before the game, the Zhangjiakou division ushered in several snowcasts, and the thick snow buried 3 "media + cabinets". The Unicom team worked hard for 10 hours, digging at a depth of 8 meters, and finally dug out the cabinet in the middle of the night and re-deployed it on the side of the track. On February 13, heavy snow fell again, and many matches were postponed due to snow, but the Unicom team of each venue completed all inspection tasks as planned as always, ensuring that the wonderful performance on the evening of February 14 was presented as scheduled.
The sword blade came out of the grinding, and the plum blossom fragrance came from the bitter cold. Like the Olympic athletes, the Unicom team has also experienced a series of trials from planning and construction to service guarantee, and has passed one test after another to achieve today's foolproof. They will also witness more excitement with their own eyes and pass on this wonderful to every corner of the world through their ingenuity.
