2.2. Augment Reality
AR is an augmented reality technology that integrates virtual information with the real world. It simulates computer-generated images, text music, 3 D models and videos into the real world by using three-dimensional modeling, multimedia, real-time tracking, intelligent interactive sensing and other technologies. In visual augmented reality, users can see the virtual world by recombining their computer graphics with the real world through a helmet display. Based on this, the future of advertising, shopping, cultural entertainment, work style will be changed.
With the advent of 5G era, with the flexible use of mobile AR, operators will innovatively launch new commercial scenarios and business models, making their application scope more and more extensive, related equipment is everywhere, and the market economy revenue has soared. It is predicted that by 2022, the overall value of AR market will reach 80 billion to 90 billion US dollars.
3.Application of AR and VR technology in broadcasting media
3.1 5G + Ultra HD video + VR
The rate of 5G is 10-100 times that of 4G, the delay is only 0.01s, the large capacity connection is 5-10 times that of 4G, and the peak speed is much higher than 4G. The transmission bandwidth of 4K video broadcast is 6075 Mb/s, while the transmission bandwidth of 8K video broadcast is 100 Mb / s, so 5G is the best carrier for ultra HD video transmission.
As early as 2018, the "5G + 8K" video live broadcast conference appeared in Hangzhou through the collaborative networking of cloud management terminal, 8K professional camera collected material video, transmitted video code from 5GCPE terminal to the local 5G core network, and realized the interconnection with the public cloud through the data cloud dedicated line with a transmission distance of 400km. Live streaming data is transmitted to Shanghai Live streaming Center and then distributed through 5G network, so as to realize real-time reception of 8K ultra HD TV sets. The live broadcast process also shows two "5G + 8K" application fields, one is the future home entertainment consumption of 8K live broadcast and on-demand, and the other is the professional application scenario of 8K ultra HD video remote consultation.
The 2019 Jiangxi Spring Festival Gala was recorded and broadcast with "5G + 8K + VR" for the first time. Four VR positions were designed on the shooting site. The 5G site base station and core network were connected through 5GCPE, and the field guidance and broadcast switching station was transmitted back through the core network special line. At the 4th "Capital State-owned Enterprises Open Day" venue, the "5G + 8K" intelligent financial media project ultra HD live broadcast special vehicle was presented for the first time.
