Historic broadcast of Super HD 8k (UHDTV) TV from UK to Japan

“TV 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 hopes to broadcast in Super Hi-Vision by 2020, although no television currently exists that can fully show off the 7680-by-4320 pixel signal.
At full resolution, those signals are transmitted at a staggering 24Gb/s, and the Super Hi-Vision camera was made possible by NHK’s development of an optical data transmitter inside that can handle the stream.”
