UHDV - Ultra High Definition Video

- Resolution: 7,680 × 4,320 pixels!!!
- Frame rate: 60 frame/s.
- 22.2-channel audio
- 9 - above ear level
- 10 - ear level
- 3 - below ear level
- 2 - low frequency effects
-21GHz frequency band
- 600MHz, 500~600mbps bandwith

The new format is four times as wide and four times as high (for a total of 16 times the resolution) as existing HDTV, which has a maximum resolution of 1920 × 1080 pixels. Because this format is highly experimental, NHK researchers had to build their own prototype from scratch. In the system demonstrated in September 2003 they used an array of 16 HDTV recorders to capture the 18-minute-long test footage. The camera itself was built with four 2.5 inch (64 mm) CCDs.

18 minutes of UHDV consumes 3.5 terabytes of data.

Preliminary response of the UHDV was somewhat negative. This was not because of the lack of the promised technology, but more in the fact that it was too good. Some viewers got motion sickness when viewing the video image because the image was so close to reality.

Mysteriox,

Oh man, might be a while before that catches on. How many terrabyte size HD's are out there for the average user? And I think I'd hate to know the cost.

Cman,

So that would work out to be roughly $4,000 for HD's? Ouch!

The format, called Ultra High Definition Video, or UHDV, has a resolution 16 times greater than plain-old HDTV, and its stated goal is to achieve a level of sensory immersion that approximates actually being there.
At a picture size of 7,680 by 4,320 pixels -- that works out to 32 million pixels -- UHDV's resolution trounces even high-end digital still cameras. HDTV, by comparison, has about two million pixels, and normal TV about 200,000 (and only 480 lines of horizontal resolution versus 4,000 with UHDV).


Add to that UHDV's beefed-up refresh rate of 60 frames per second (twice that of conventional video), projected onto a 450-inch diagonal screen with more than 20 channels of audio, and you've got an impressive home theater on your hands.........................

I thought my HDTV was pretty close to real life, so I'd probably crap my pants if I saw the UHDV

MysterioX,

I'll be interested to see it but it makes me wonder. If I read correctly, for this to work, won't broadcasters have to upgrade all of their equipment for this to work?

Given that most stations have already paid major moolah just to upgrade to normal HDTV, won't this take at least 20 years (or so) before its economically feasible? Or implemented?

Yeah personally i think it's too far ahead for us at the moment.
I've seen HD and to be honest that's enough for me...
I can only see a good use for it at the movies and after i read what you said about 14 250gb hard drives just for a few minutes of footage its gonna be a long while until our computers can handle it and to think i tried to search for UHDV sample's on google!

If anyone else finds anymore info about it be glad to hear it.
