"A gig by The Charlatans has been sent to Japan in a first-of-its-kind broadcast of Super Hi-Vision TV. The technology, 16 times sharper than HDTV, has been developed by Japanese public broadcaster NHK. The standard could be used on giant public viewing screens, some of which may be in place for the 2012 Olympics.
NHK hope to broadcast in Super Hi-Vision by 2020, although no television currently exists that can fully show off the 7680-by-4320 pixel signal. The "full HD" currently available means a display of 1920 by 1080 pixels - a quarter the number of pixels both vertically and a quarter horizontally."
