A prototype digital video system producing images of such high quality that the human eye struggles to distinguish them from reality has been developed by Japanese engineers.

The system, called ultra high definition video (UHDV), achieves image resolution 16 times greater than even the most advanced video broadcasting technologies now available.

Its developers at the Japan Broadcasting Corporation (NHK) said the system could be used to provide an ultra realistic 'immersive' viewing experience when, for example, showing sporting events.

UHDV displays images with 4,000 horizontal scanning lines, compared to the 1,000 offered by the current state-of-the-art high definition television (HDTV) technology and just 625 for standard TV broadcasts.

just imagine how much storage they will need to hold 2 hour movie

I want it now!!


I'm going to call up Dish and ***** them out for not carrying UHDV.

Now I'm gonna have to buy a new projector, new switcher, new playback devices, new UHDV receiver. I can just imagine the reaction from the wife. "but honey, what do you mean I can't get a new projector, it's better than reality!"


Seriously, I truly hope this comes to pass in the next decade. Maybe they can find a way to fit the UHDV signal within the existing HD bandwith with out compromising the quality.

From the article ...
Quote:

They have now built a disc recorder system made up of 16 HDTV recorder units with a capacity of about 3.5 terabytes, allowing them to shoot 18 minutes of UHDV footage.

So that would be ... 23 terabytes for a two hour movie? Wow ...

Even the 4,000 scanning lines will fall by the wayside in 40-50 years. Progress in quality of picture (and sound to a lesser degree) will never cease. Making a profit will drive it. And I say that in a good way! Bottom line, enjoy what you're seeing and hearing today. knowing tomorrow everthing will be of higher quality, but do not worry or fret about it !

By then we wont need TV's we will be in holodecks or just put on a special pair of glasses!

Uh, what is the point with such high resolutions if the human eye can't discern them? Bigger screens?


This would be great for VR environments, but totally impractical for home viewing.

peter0302..


Remember, my friend, until you see something better, you believe you are seeing, hearing the best availlable. And you may be at that point in history. But progress continues, remember. What we are seeing in 2003 will not look very good in..say..2043.

Companies must always come out with newer, better products..or this old world would fold up..and fade away. And this shall not happen.

That's exactly the point.

That does seem logical.

Yes, the equipment they are using right now appears impractical. However, my understanding of the article was that the technology is in the development stage.


Would you not want a VR-type environment in your home?

You MIGHT not want to have that conversation with your wife..... porn might be the only thing left for ya!

Recall another article discussing similar systems and the proposal was to allow viewers to zoom in areas that interested them with some graphics-input device. Maybe all that unresolvable detail would be gobbled up rapidly--with still more required--if scenes were delivered in high-quality stereoscopic 3D. Of course 3D HD is also possible without extreme total detail and bandwidth. -- John

By the time we'd need to worry about recording that stuff, people will be talking about their latest Petabyte, or Exabyte media servers. |-]

'things are moving fast'.


The bottleneck for progress will be the consumer. The majority will not get into HD until 8 years from now. And, at that point, you cannot expect the public willnot be moving up to another level until 15-20 years after that.

Well, maybe, but there comes a point where you can get out of control. Higher numbers just for the sake of higher numbers isn't always better. Take audio - now they're pushing 96 KHz audio as superior to 48 KHz. The human ear can hear no more than 24 KHz, translating to 48 KHz sample rate. Scientifically, 96 KHz is no better than 48 KHz. But yet they're still trying to sell it to us.


Instead of higher numbers, let's put our resources to better things. Alternative display devices, such as paper-think flexible screens, or 3D holographic projection. Those would be a lot more worthwhile than having the resolution of a 35 mm projector in your own home.


This is also typical of Japanese electronics companies. So rarely do they come up with revolutionary innovations of their own, but rather just take what's already been done and make it bigger. Now they're doing it in the extreme. So what, we can become obsessed with and throw our money away for resolution we don't need?

Wow baby am i dreaming or what ?


Bring it on here., now

I'm just sick about this. I'm getting ready (or was) to buy my first ordinary HDTV.

 

[peter0302]

See this is what I'm talking about. Don't hesitate to buy an HDTV because of this. It'll be a decade before this becomes affordable, or even before there's a practical application for it. 56" screens are NOT suitable for this type of resolution.
