Recently, the China Academy of information and communications announced that the "Winter Olympic wisdom network" created by China United Network Communications Limited(600050) has taken the lead in passing the "IPv6 +" test and evaluation, and won the "IPv6 +" ready1.0 for the first time in China 0 certificate. In the process of private network construction, China United Network Communications Limited(600050) fully considered the flexibility of IPv6 + protocol, combined the smart Winter Olympic private network with IPv6 + innovative technology, and built a high-quality private network based on IPv6 + technology base, which can meet the high-quality and speed unlimited access needs of more than 150000 terminals. According to the China United Network Communications Limited(600050) official website, this winter Olympics is the first application of IPv6 + technology in large-scale events.
5g enables digital Winter Olympics. As the venue for the opening ceremony of Beijing 2022 Winter Olympic Games, the bird's nest has achieved 5g full coverage through China United Network Communications Limited(600050) careful planning and deployment. At the opening ceremony, China Unicom 5g network met the needs of nearly 40000 live audiences and performers to send and receive short videos, video calls, live broadcasts and other services online, as well as the audience's immersive live broadcast experience. The mobile network team innovatively adopted eight "black technologies" such as "distributed large-scale antenna technology", "space frequency multi-dimensional 5g capability integration", "carrier aggregation", "comprehensive SA network", "5g slicing", "cell merging", "intelligent dynamic beam" and "large uplink", so as to create an advanced 5g network with full coverage and extreme capacity for the bird's nest, which has increased its 5g capability by more than 20 times compared with 4G, Fully meet the 5g network experience of core athletes and the network requirements of tens of thousands of spectators.
According to BOE's official website, the overall hardware support and software system of the "snowflake" form main torch platform of the East Olympic Games are independently developed and designed by BOE. At the moment when the torch was lit, the giant snowflake screen radiated from the center to the surrounding, shining a wave like bright light layer by layer. Behind the fast changing and perfect synchronous display screen, the Boe Technology Group Co.Ltd(000725) IOT technology system and the self-developed synchronous / asynchronous compatible messaging system were adopted. The asynchronous centralized control can quickly distribute large-scale video content in a very short time, Synchronous centralized control ensures that 102 double-sided screens achieve millisecond response; In addition, the highly redundant control system of "main circuit + loop" backup ensures the ultra-high reliability of the broadcast control system of the flare station. At the same time, by using Lora (long-distance radio) low delay control system and synchronous playback time correction technology, we can further ensure that the command is issued without fail and realize the perfect coordination of video images. In addition, the stage floor of the opening ceremony is the largest 8K UHD ground display system at present, with an overall area of 10393 square meters. BOE adopts multiple picture fusion technologies with 8K + resolution. The super large-scale optical correction algorithm can perform pixel level optical correction for each display picture, showing 100000:1 ultra-high contrast, 3840hz ultra-high refresh rate, and 29900x15096 ultra-high resolution ultra-high definition gorgeous pictures.
Intel ® The powerful computing power and advanced AI algorithm of 3dat make it possible to realize real-time data acquisition and analysis with large range, large number of people, high accuracy and low delay. The real-time "interaction" between the LED large screen system laid in the National Stadium and the actors has become a highlight of the opening ceremony of the Winter Olympics. This real-time interaction is not the result of accurate rehearsal, but from Intel ® 3dat three-dimensional athlete tracking technology. The "Ai based real-time special effects system for large-scale performance" customized for the scene of the Winter Olympic opening ceremony based on Intel's 3dat technology is the key technology to realize the creativity of the whole program. Intel ® 3dat 3D athlete tracking technology is a complex system, which is composed of three subsystems: camera information acquisition, data analysis and artistic effect rendering. Its core algorithm is real-time human body detection and position tracking technology based on computer vision and AI. It is precisely because this system runs in the third generation Intel ® xeon ® On the scalable processor, its powerful computing power plus advanced AI and computer vision algorithms make it possible to realize large-scale, large number of people, high accuracy and low delay real-time data acquisition and analysis, and make this huge LED screen laid on the ground of the National Stadium "interactive".
Investment suggestion: it is suggested to pay attention to the valuation improvement of relevant sectors brought by the implementation of 5g applications in the middle and later stage of construction, and the relevant sub sectors of Gigabit broadband, 5g main equipment, cloud computing and Internet of things
Risk tip: 5g construction is less than expected, and the growth of traffic demand is less than expected
