Yesterday, the BBC broadcast a gig by British band The Charlatans in Super Hi-Vision between London and Tokyo, its first ever live transmission using the technology.
A specialist camera, one of just three in the world, was used to film the band's live set, while an audience watched in a different room on a 103-inch plasma TV, developed by NHK. Another audience in Tokyo watched the gig on an even bigger screen.
NHK hopes to start broadcasting in Super Hi-Vision by 2020, although no TV set exists that can fully support the 7680x4320 pixel signal, as current 'full HD' sets only display 1920x1080 pixels.
The Japanese broadcaster has worked with the BBC's Research and Development division to compress the massive video signals for Super Hi-Vision. At full resolution, the service transmits at a colossal 24Gbs, compared to around 16Mbps for normal HD.
