Ultra High Definition Television (UHDTV) took an important step towards becoming reality when experts reached agreement on most of the pertinent technical characteristics of this new standard for television. UHDTV marks a leap forward beyond the current standards for high-definition television (HDTV) and brings new levels of visual quality thanks to enhanced resolutions.

“UHDTV promises to bring about one of the greatest changes to audio-visual communications and broadcasting in recent decades. Technology is truly at the cusp of transforming how people experience audio-visual communications,” said Christoph Dosch,  chairman of the broadcasting service study group.

A number of companies are already working on technologies like quad-FHD (3840*2160, QFHD) and even ultra high-definition (7680*4320, UHD, UHDTV or Super Hi-Vision [SHV]). Cameras and screens capable of filming and displaying QFHD and UHD video are very rare these days, but they do exist: earlier this year Sharp demonstrated a direct-view 85" LCD display capable of 7680*4320 pixels at 10 bpp.

Demonstration of 7680*4320 UHDTV with 22.2 multichannel sound using 85" LCD at ITU HQ by ITU staff and NHK (Japan Broadcasting Corp). Both screens are the only 2 prototypes are they have been presented to the press.

The experts, which include scientists and engineers from around the world, have been working together for several years in the ITU study group on broadcasting service (ITU-R study group 6) to jointly develop and agree on the technical specifications that will successfully create ‘UHDTV’.

“The 'relationship' that a viewer has with television viewing is linked to the overall experience of the picture and quality of sound. The extremely high quality of UHDTV will have a definite impact on our lifestyle and on our engagement with the programmes we watch,” said David Wood, chairman of the concerned ITU working party in the broadcasting service study group.

A demonstration of UHDTV was provided by the Japanese public service broadcaster NHK at ITU earlier this month. The screen displayed a staggering 33 million pixels (7680*4320 resolution), compared to a maximum 2 million pixels (1920*1080 resolution) for the highest quality HDTV screens available today today.

In September 2011,  a trial UHDTV link was arranged between London and Amsterdam and plans are under way to cover part of the 2012 London Olympic Games in UHDTV for screening at public venues around the world.

“UHDTV will create an immersive experience for viewers and will generate a host of new business and marketing opportunities,” said Hamadoun Touré, ITU Secretary-General.

This is pretty much a complete waste of time. It might be useful in projectors or for people that like to sit 1 foot away from their TV. The fact is, on a TV less than 55", sitting 6 feet away, most people can't tell the difference between 720p and 1080p. 7680*4320 resolution won't do much for people unless they have a 50 foot screen.

you mean games or just the screens because all screens are 60hrz standard. if you want higher fps games than you need a better computer. and you probably can tell the difference when you see an edge and if yo want to render till the smallest detail like a fens. so you can see all the polygons on the screen.

I believe Patrick was referring to the framerate at which TV/Film is shot and broadcast, which is about 25 fps, not the refresh rate of the TV/Monitor itself. Now if we could get an NTSC update for this new UHDTV so that everything can just be shot in 60 FPS without the need for any "pulldown" or other tricks to match various formatting variances, we should be good.

Oh god no. Have you seen TVs interpolating 24fps to 120fps? It looks like its shot with a camcorder. No thanks, as weird as it sounds, I'd rather watch 24/25fps movies and shows.

24 fps is PERFECT for movies, but 60fps or more is PERFECT for live action scenes like F1, football, etc

This is true, forgot about sports and whatnot.

I'd prefer to see improvements to the handling of high-rate-of-change scenes--not motion blur, but the digital artifacts that are noticeable during action scenes. If they crank up the resolution but don't increase the bits per second well beyond what we have today (which isn't very good) proportionally, what's the point? Great talking heads and still shots?
