The Control Room in TVC during the Super Hi Vision trial
On Wednesday in Television Centre ´óÏó´«Ã½ 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 ´óÏó´«Ã½ R&D blog:
The main camera, the biggest in the pictures, and the key reason for this demo, was an NHK 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 ´óÏó´«Ã½, the image is actually being down converted from its raw form!
´óÏó´«Ã½ 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.
There's a report on this week's Click and on next week's Digital Planet on ´óÏó´«Ã½ World Service.

There is absolutly nothing "historic" about this publicity stunt. It was probably designed to distract from Sky's opening of the first 3D channel in the UK which is far more historic.
What the ´óÏó´«Ã½ don't tell us with this stunt is that they have no plans what ever to deliver 3D to licence payers let alone Super Hi Vision. In any case this was not a real demonstration of Super HD Vision as it only used 5.1 surround sound where as 22.2 sound channels should have been used.
The ´óÏó´«Ã½ cannot even deliver a decent HD channel. ´óÏó´«Ã½ HD is 1440x1080 which is below the 1920x1080 standard for HD. Sky is transmitting 48 HD channels and the ´óÏó´«Ã½ only contributes one low quality part time channel.

So how come the ´óÏó´«Ã½ broadcast in 1440x1080, and is almost the only channel to do so?
If the ´óÏó´«Ã½ cannot do HD now, it makes me suspicious that when Super HD finally does become available then it too will be broadcast at a lower resolution and bitrate than the rest of the industry, no doubt accompanied by ´óÏó´«Ã½ claims that people can't see the difference...

and the whole HD not being good enough quality for sky viewers surprisingly doesn't affect virgin media homes, I wonder why...
