Groundbreaking transmission trials of the Super Hi-Vision video format are being planned for later this year.
Super Hi-Vision, also known as Ultra High Definition, is proposed as a successor to the high definition standard. The specification includes 7680x4320 resolution images and 22.2 three-dimensional surround sound.
Two world-first test transmissions of UHD video will be carried out during the Amsterdam IBC 2008 technology show in September.
In the first, video will be fed by SIS Outside Broadcasts, formerly part of the BBC, over an ultra-broadband fibre connection to the event.
Another test will see Super Hi-Vision pictures transmitted live via satellite from Italy and displayed at the IBC show.
The BBC's research and innovation team will be showing compression and decompression of Super Hi-Vision using an algorithm they have developed.
Japanese broadcaster NHK has been leading the early development of the format. Dr Kenkichi Tanioka, director general of NHK's science and technical research labs, said: "It is a tribute to the alliance of forward-looking companies working on this project that we are confident all will be well.
"In particular, I know that my colleagues at the BBC and RAI would like to thank our industry partners who are investing heavily in broadband and satellite capacity over an extended period to make this work."
