Some time ago, there was good news from the 5G NR broadcast, which focuses on watching TV without traffic,Radio and Television will work with China Mobile to carry out pre-commercial 5G NR broadcasting in Beijing, Shanghai, Shenzhen and other places, enter after the end of pre-commercializationOfficially commercialized
Since the approval of the project at the 3GPP plenary meeting at the end of 2019, 5G NR broadcasting, which has gone through "twists and turns", may be officially launched in the near future.
As a new operator with its own radio and television attributes, radio and television will naturally take a "different" path with the three major operators. Among them,5G NR broadcasting that can watch TV without trafficIt has high hopes for radio and television, and regards it as an "excellent representative" of 5G innovative applications, and works with operators, chips, terminals and other industry chain partners to promote the commercial use of 5G NR broadcasting.
5G NR broadcasting is a collaborative transmission mode between mobile cellular base stations and radio and television transmission towers to provide new interactive broadcasting and converged information services to various intelligent terminals.
To put it simplyThe base station is regarded as a "transfer station" to send the signal of radio and television to the user terminal, we can broadcast live events and other content through the mobile app**TV. Since the signal is received by broadcasting, there is no need to consume mobile phone data.
In addition, for application scenarios such as public safety, IPTV, and hot spot live broadcast, in the tower broadcast mode, it can ensure a wider range of signal transmission and send public service content; In the small tower broadcast mode, the coverage transmission is more flexible, and it supports the sending of popular content such as events and live performances, including the current popular AR, 360-degree full-scene and other high-definition** applications.
5G NR broadcasting is equivalent to unlocking a new way to open for us**TV programs and other **content, compared with the previous mobile phones, tablets and other portable terminals to short**, watching dramas, all need to consume data traffic.
The first advantage,Even if the phone does not have a SIM card inserted, it can receive a TV signal
The second advantage is that 5G NR broadcasting is in accordance with 5G international standardsThere is no need to change and upgrade the existing core network, base station, mobile terminal and other hardware equipmentIt not only reduces the difficulty and cost of application popularization, but also helps accelerate the progress of 5G NR broadcast online adaptation terminals in the future.
The third advantage is to break down barriersSupport cross-carrier service deliveryUsers of the four major operators can receive 5G NR broadcast signals; At the same time, 5G NR broadcasting uses 5G multicast broadcasting technology to transmit data, which can not only improve transmission and coverage efficiency, but also perfectly avoid network congestion.
But for the market, the most difficult thing is the formation of user habits. In the vast majority of outdoor scenes, there is not much demand for TV programs, and there is mostly WiFi network coverage in indoor scenes.
In addition, there are a number of mainstream live broadcast, long, and short* applications on the market, and how to "stand out" in these popular applications is a big challenge for 5G NR broadcasting, which has not yet been officially commercialized.
At present, on the terminal chip, radio and television, together with UNISOC and ZTE, has fully realized 5G NR broadcasting based on the 3GPP R17 standard, and completed the end-to-end business demonstration of R17 NR broadcasting, which means that in the future, mobile phones equipped with UNISOC 5G chips will automatically have the function of receiving 5G broadcasting.
In addition to the promising 5G NR broadcasting, based on its own characteristics, radio and television has also launched 5G channels and 5G cloud TV and other special applications to create "future TV", innovate 5G consumer personal applications, and continuously expand new services.
Do you think 5G NR broadcasting can become a "killer feature" for radio and television in the future?
