Cultivation in the epidemic | 5G+4K remote production
In recent years, the fifth-generation of mobile communication system, 5G, has become a hot topic in the field of communication and academia, and 2019 is also known as the first year of 5G technology. The application of 5G in the broadcasting industry has also become a subject for the entire broadcasting industry to explore new technologies in the future.
At the beginning of 2020, the Covid-19 spread rapidly around the world. In this epidemic time, the isolated living environment determines that traditional method of program production can no longer be carried out. The advantages of remote production are particularly prominent under this situation. .
In this special time, SMT relies on the technical advantages of original large-scale long-distance remote production, based on the larger bandwidth and lower latency of 5G network, which opened up the 4K remote production linkage on the public network and realized an "anytime, anywhere" method of remote production.
In 2018, SMT has already made some achievements in the field of remote production including the completion of remote production test for Chinese Football Association Super League, the LPL 8th anniversary (45 km) urban transmission, and the 25-site plus 6-day full-range remote production of Wuhan Military Games. To produce remote production on the public network environment can greatly reduce the threshold conditions for remote production, and effectively saved the energy consumption in the coordination and construction of dedicated lines.
The Meaning of Public Network Transmission
Save bandwidth resources
Compress the video and audio feeds, use the minimum bandwidth resources to transfer back to the production center, and even in an ordinary home network environment can produce a small-scale production.
Overcome regional restrictions
Long-distance feed transmission is no longer subject to regional restrictions, cross-province or cross nation transmission can now be achieved, and that will inspire more imagination of new area in broadcasting business.
Remote Communication system on public network solves the problem of cross-region
SMT takes the communication system as a starting point and has now completed the test of remote transmission of communication system on public network. In the actual program application, various communication problems that caused by cross-region in remote production can be completely solved. The successful application of the remote communication system can helped to achieve smooth communication in cross-region program production and some other aspects, and escort the success of program’s live broadcast.
The upgrade of cross-region connection technology for remote communication system on public network
The success of transmission of communication system on public network has driven SMT's further attempts. Through VPN, EIP and other technologies, LAN network is established on basis of the public network, those devices that could only "shake hands" in the same room before can now be connected in two separated locations. Video (4K), audio, call, TALLY, control and other indispensable system links in the conventional production process can now be directly transmitted in this way.
Since 5G technology has been rapidly developed, SMT has completed the precise layout of 5G + 4K link technology of remote production on public network, and establish remote production environment merely through public network. It is foreseeable that in the near future, no matter in the remote live broadcast of small to medium size sports events or in a remote production of e-sports, or marathons, bicycles and other related games, remote transmission on public network will definitely create a new world for it.
