Super Hi-Vision Trial: Reaction
The Control Room in TVC during the Super Hi Vision trial
On Wednesday in Television Centre BBC Research and Development and Japanese public broadcaster NHK sucessfully transmitted Super Hi-Vision Footage of the Charlatans playing live to Japan. There was widespread coverage and some excitement.
Ant Miller on the BBC R&D blog:
The main camera, the biggest in the pictures, and the key reason for this demo, was an NHK Super Hi-vision camera, which records an image of mind blowingly high resolution, 33Mega pixels per frame. These images were displayed around the studio on 4k (4000 horizontal lines resolution) monitors- even though these are the highest definition monitors in the BBC, the image is actually being down converted from its raw form!
BBC News' headline described the event as "historic". Here's their video report:
High-quality 1080p images are already impressive (and disturbing) enough. With Hi-Vision, we'll be able to make out every fine detail of each pore on the faces of TV personalities.
Of course, transmitting this much data was a challenge in itself, and this is what the researchers at the Beeb's R&D labs have been working on. As well as developing some advanced compression-algorithms, they combined multiple high-speed internet connections across the planet to create a single 350Mbps link. Because of the massive amounts of bandwidth required, satellite broadcasts were prohibitively expensive, forcing the team to look for another option.
