Science and Technology plays an important role in helping in the long river of human history。Looking back at history,The "Pyeongchang Winter Olympics" held in South Korea in 2018,South Korea KT (KOREA Telecom) jointly deployed the most advanced 5G communication network at the time with Intel,Set up 5G lines in the main Olympic venues in South Korea,Support video broadcast、Virtual reality scene、Wireless Networks and other applications,And provide the participating teams and venue audiences with the named Gigabit network speed service。But by technical restrictions,The 5G technology application at that time can only be regarded as test -based commercial,The audience's perception and experience are relatively limited。2022,The Beijing Winter Olympics will fully apply 5G network。5G technology empower the Beijing Winter Olympics,It is both the development opportunity of new technology,It is also the inevitable development of the times。Under the support of mature 5G technology,The Beijing Winter Olympics in 2022 will bring a new technical show and visual feast to the audience。

5G to make high -speed video broadcast become reality。Academician of the Chinese Academy of Engineering, He Hexuan, believes,"The Winter Olympics is the best test of the three major application scenarios of 5G"。The "scene" here mainly refers to enhancing mobile broadband、High reliability, low latency and large connection。bet365 live casino games If the bandwidth is not enhanced,will cause "traffic congestion"; the delay problem directly affects the poor view of the scene and the non -scene;,It's about social development,Everyone interconnection in 5G will drive and accelerate the informationization process of the entire society。After the hardware of the new infrastructure is completed,Everyone、"Share sharing together" for characters and things,It will greatly promote the development of society。

Single for the Winter Olympics,For example,Falter skating project has fast speed、Multi -rotation and other features,When visual communication, you need to present a picture of ultra -high -definition TV。The resolution of a 4K picture is 3840 × 2160 pixel,8K resolution can reach 7680 × 4320 pixels,4 times of 4K screen。There is a device provider to test the 8K format video picture 1 minute length needs to occupy nearly 200GB of storage space。With the storage space without compression,This ultra -high -definition picture cannot be transmitted at all in the 4G era,8K screen requires the network access rate to reach 100m or more,The peak of the 4G network can barely achieve 100M。2019,There are Chinese operators to measure the 5G network,The result has reached 1.25g/s,Compared to 4G network,Speed ​​up 100 times。It can be said,The improvement of the network environment makes the ultra -high -definition presentation gradually embark on the stage of the stage of TV broadcast。

5G to let high -speed three -dimensional video shooting instantly。Many projects in the Winter Olympics have a high speed。For example,2002,French Bet365 lotto review player Philippe Goitschel set a world record for high -mountain skiing -250.7 km/h。Excellent short track speed skating athletes can be nearly 50 km/h。How to show the panoramic view of high -speed exercise in front of the world? Always,The bottleneck that is difficult for practitioners to break through,It is a hardware problem for high -speed equipment。2019,In the World Wushu Championships held in Shanghai,Some media launched "Freedom Viewpoint Technology" during live broadcast,This technology is arranged with a high -precision camera through multiple points,The moment of the instantaneous screen that can be used to shoot instant athletes。Visitors can look back at or solidify the scene of the dynamic 360 degree time according to their needs。In the past,The audience can only watch the single perspective race according to the photographer’s same -pass screen,Even at the scene,It will also be limited by the venue and cannot view the corner。with the support of 5G,Sports videos can be performed without dead angles through drones。For example,The Air Skills Project of the Winter Olympics is strong due to viewing,Known as "air ballet",But because of a single perspective、Establishment of air action,It is easy to bring some regrets to the audience。and the combination of 5G and "Free Perspective Technology",Then it can solve such problems,According to the needs of the audience,Technically "perfect" presents the athlete's up and down、Left and right、Various attitudes before and after。

If the 4G network can allow the audience to achieve a flat view,So,5G network can spread other various technologies bet365 best casino games at high speed、Low latency、In the case of large storage, "like tiger add wings",so that the audience has a three -dimensional view,More "immersive"。

Virtual Reality Technology (Virtual Reality,VR) can realize time and space conversion。Now,Experience ice and snow project does not need to visit ice and snow,VR allows people to switch scenes in summer inflammation,and storage through the cloud,The exotic experience of the audience can be easily realized,time difference、Space asymmetry、Language barrier,or even seasonal conversion is not a problem。The Pingchang Winter Olympics allowed some audiences to experience the visual feast brought by "5G+VR" on the spot,The Organizing Committee provides a 360 -degree VR service、Synchronous perspective service and full scene view service。Current,Similar Olympic experience has been developed and mature around the business districts of major cities in China。For example,When watching a movie waiting,,You can experience the fun of skiing at the virtual ski resort next to the theater。Through "5G+VR",The audience can get a sense of presence in real time。

​​Modern media technology especially emphasizes human -machine interaction and social interaction。5G transmission technology and big data storage complement。Based on this,Various applications developed according to user habits will accurately push the information they want to know。Multi -mode state language research、Fine granularity analysis and depth information mining,Both the audience can control the holographic information across the language,can also make them targetedly choose bet365 Play online games the details they want to follow。In the past,The commentator sitting in the live broadcast room needs to accumulate for a long time to be broadcast,The current database can basically realize real -time interaction。For example,About some well -known athletes,We can quickly generate the latest resume through the information reported publicly,Even the template is ready -made,Previous exercise results、Training status、Exit and come back and other information,All will be clear at a glance。Of course,Some content still requires people to make judgments。In short,This kind of interactive activity,In the era of the mobile Internet, it became less profound and mysterious。

,5G can make the real -time data of the athlete more "clear",so that they can get more comprehensive and scientific "care"。The habitual measurement unit,IMU) The wearable sensor device represented by the representative,It has been used in a large amount of daily sports training。​​Related strength、strength、frequency、Technical action and other data,It has been presented by visualized data,Technician through analysis,Then feedback to the coaching team in the form of instructions or reports。​​Some intended or attemptive、Technical action of possibility,It can also be implemented through bionic forms or robots,Athletes can also learn through VR and other devices,Implementation of simulation training。

The consumption of athletes of the Winter Olympics,Usually bigger than ordinary athletes。They need to consume at least 3000-4000 calories per day,It is twice the average daily bet365 best casino games heat of ordinary people。In the diet,carbohydrates can provide them with daily energy,while fat helps energy maintenance。So,How to eat three meals per day、What to eat requires big data to help research and judgment。During daily training,can supplement energy according to the training intensity。According to the National Academy of Sports Medicine (The National Academy of Sports Medicine),In cold weather,About half an hour before training,It is best to eat foods rich in carbohydrates,The purpose is to ensure that you have sufficient myoggly glycogen during training。After 1 hour of training,then need an appropriate amount of water。Training time exceeds 1 hour,It is necessary to ensure that appropriately intake carbohydrates every 1 hour to supplement the lack of energy。But the diet of athletes at the Winter Olympics should be more detailed,According to the situation of training and competition,Adjust the diet in time,To ensure that the athletes have abundant physical strength。So say,How much to eat and how to eat athletes,It can be calculated according to many conditions。

Athlete from training to rehabilitation,It can be said that "clothing, food, housing and transportation" is in the "control" of big data。Of course,This is an ideal mode。With the development and application of 5G,This "care" can be continuously enhanced。Based on 5G,The various data of the athletes can also be more "clear" due to instantaneousness,Its diet、Training, etc. can also be developed through 5G technologies for coordinated development,More fixed quantification and science。

5G technology makes people who love sports around Bet365 lotto review the world have more expectations for the Beijing Winter Olympics。To achieve a more colorful scene,We need to hurry up and do well in talent training and technical conversion and application。In -depth fit of sports and technology,can be rejuvenated to greater vitality; technology can achieve more scene applications by using sports,can also get more rapid development。
