6 Immersive Media Short term
400Mbps Class Millimeter-Wave Wireless Transmission Technology for Contents Production
Wireless relay of ultra-high-definition 360-degree video
Outline
STRL is conducting research into large-capacity transmission technology used for 360-degree contents production, to help provide realistic immersive-media services. This demonstration shows real-time transmission of ultra-high-definition 360-degree video using a wireless transmission system with a 400-Mbps-class transmission capacity using millimeter waves*1.
Wireless transmission using millimeter waves
By using millimeter waves in the 42-GHz band allocated for broadcast purposes, cameras can be made wireless, enabling live relay of ultra-high-definition 360-degree video in locations where it is difficult to lay cables.
Expanding transmission capacity using spatial division multiplexing transmission technology
STRL has developed MIMO-SC-FDE*2 technology for spatial division multiplexing transmission of single carrier-modulation signals at the same frequency with smaller transmitters. By using the wide bandwidth of millimeter waves, this has achieved a 400-Mbps-class transmission capacity, around twice that of the conventional system.
[Future plans]
STRL will develop 700-Mbps wireless transmission technology to further improve the definition of 360-degree video by 2025.
