A graphics system and editing platform are among the innovations developed by Japanese broadcaster NHK for the Super Hi-Vision (SHV) production of the London 2012 Olympics.

A lightweight SHV camcorder will also be previewed, but not used in the trials.

Uncompressed signals will be taken from Olympic venues back to Television Centre, where the BBC is building a production suite to generate a live feed and 45-minute highlights reel for showing on giant screens in the UK, US and Japan.

“This includes an ability to render the world’s first SHV graphics,” said Tim Plyming, project executive, digital, and editor, live sites, BBC London 2012.

Pictures will be streamed across the UK’s Janet research network, a 20GB IP network, to Washington via other academic networks, and streamed to Tokyo and Fukushima by telco NTT.
