DOCOMO has achieved what it claims the world’s first wireless real-time transmission of 8K video deploying radio access technology for 5G mobile communications systems, in a trial jointly conducted with Nokia.
The transmission of ultra-high-resolution 8K video was achieved by a combination of an experimental system jointly developed by DOCOMO and Nokia, and H.265/HEVC encoding techniques developed by NTT Media Intelligence Laboratories. The system uses beam-tracking techniques to transmit millimetre wavelength signals at an extremely high frequency of 70GHz.
In the trial, 8K video of 48Gbps – a bit rate four times greater than 4K video and 32 times than Full HD – was compressed by the encoder into signals ranging from 145Mbps to 85Mbps and successfully transmitted without delay.
Glenn Booth, Vice President and General Manager, 5G Business Line at Nokia, commented: “We are excited to be collaborating with DOCOMO to shape 5G and show how this technology can be used to dramatically enhance the delivery of services such as video. This world’s first demonstration is a clear indication of our progressive leadership in 5G. We will continue to leverage our expertise and work with industry leaders including DOCOMO to drive further innovation in the industry.”
