Data show that the national advertising revenue in 2020 was 207.527 billion yuan, up 11.30% year on year. Among them, it is worth mentioning that the traditional radio and television advertising revenue was 99.885 billion yuan, down 9.13%, while the new media advertising revenue was 82.876 billion yuan, up 68.49% year on year.
With the advent of 5G era, 5G network technology has promoted the rapid improvement of immersive experience in the new media industry, video business has become the development form of mainstream media, image definition has also been improved from HD to uHD 4K / 8K, and scene video has also shifted from two-dimensional planar to VR and free perspective immersive experience.
2.1. VR panoramic video
VR technology will be widely used in various fields, including video games, tourism and entertainment, live streaming activities, medical education, and construction engineering. VR panoramic video technology brings users into the 360 panoramic virtual space, providing users with an immersive experience. For example, smart gloves, which transfer the surface of the hand through more than 300 tiny air bubbles, make the user feel the weight of the stone or the ripples of the plant meridians. The immersive learning experience of VR education can help learners quickly digest difficult knowledge points and create a good learning environment for them.”
In the 5G era, the development of the video industry mainly focuses on the “5G + VR video” business in the new media form of VR panoramic video. The VR market is expected to reach $300 billion in 2025, and VR will be widely used in education, social networking, shopping, navigation, and gaming.
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.
3.2. 5G + VR Panoramic Video Live Broadcast
In the era of omnimedia, radio and television new media can improve its capabilities of HD live broadcasting and online and offline interaction by expanding its functions on the basis of the existing studios. Through the fusion application of “5G + VR” panoramic video immersive technology, the studio can create an immersive 720 free viewing vision, so that the host or live guests can feel as if they are on the scene.
