BBC, the world's largest broadcaster, sent a Super Hi-Vision TV broadcast of a band gig to Japan's national public broadcasting organization on Wednesday in a successful transmission test of the experimental digital video format.

NHK's powerful optical data transmitter inside the Super Hi-Vision camera captured a live set by the group The Charlatans in and streamed the video at 24Gb/s to a large screen in Tokyo where it was watched by locals. The video will be rebroadcast on 6Music's website on Thursday for the U.K. audience.

The Super Hi-Vision TV can generate a 7680-by-4320 pixel signal, which no TV could show yet. The highest resolution that current high-definition display can show, 1920 by 1080 pixels, is only one-fourth of the Super Hi-Vision's signal.

BBC is planning to use the technology in capturing the 2012 Olympics in London and showing the video on test screens.

NHK plans to broadcast in Super Hi-Vision by 2020.
