Goodbye HDTV, hello 3-D TV.

Well... Very Happy

@David cv,
Not surprising... given that the latest TVs boast up to 240Hz refresh rates (progressive nonetheless) doing shuttered and polarized 3D becomes much easier since you won't have the visible flashing and lines you get with the standard 29.97Hz interlaced NTSC we all grew up with and loved.

I expect video games to take full advantage of this in about two or three console generations... once there's a large enough install base of TVs which can fully support this option without causing headaches (think the Virtual boy).

Very Happy If they make another 1, they better jive Jaws something other then paper teeth that can't bite a O2 can.

@David cv,
I really don't see this happening anytime soon unless they find a strong alternative to those goofy looking glasses you have to wear.

That's like saying that space travel won't take off unless they find an alternative to those goofy looking spacecraft.

The only other method is holographic technology. We have a way to go on that front. The glasses are what make the illusion work, its been that way since red/blue anaglyphic images. Now televisions have caught up and can display proper images without being overly expensive.

Not at all.

The fact that a TV requires special equipment for it to work is going to make is less preferable to a TV that requires no special equipment. People don't like having to wear glasses just to watch the TV in their living rooms, especially when they are doing other things.

We've had 3d technology for decades and yet it's never really taken off.

We definitely have had 3D technology for decades. The trick is that TV technology has finally caught up to such a level that 3D won't give the viewer headaches after a half hour of watching. NTSC is 29.97Hz interlaced, so there's a flicker to begin with. When you split that again to do stereoscopic images, the flicker is unbearable. In movie theaters, they can use special equipment to overcome this (some use two projectors, others use high framerate projectors). We in TV land have had to deal with either watching 3D in red and blue or popping Advil like M&Ms. Now with 120Hz and 240Hz screens, you can shove two overlapping images onscreen fast enough to retain a crisp display.

As for the glasses, there really isn't a way around this. Something has to handle the stereoscopy or polarization on the user's end... something has to translate two 2D images into a proper 3D one. Anaglyphic, polarized and shuttered glasses are the best (and currently the only) way to do proper 3D. Its been that way for ages because that's how the illusion works... one eye is shown a slightly different image than the other, simulating a feel of depth in what you are seeing. The only other 3D is holographic, which has actual depth to its imagery.

Either make it or fake it, those are your only real choices.

Actually 3d television sets are being developed that do not require glasses.

That is impressive, although still not 100% sorted out, however it still lacks the ability to bring depth towards the viewer. Looking at a TV and seeing depth into the TV is one thing, seeing depth come out of the TV is totally different. You won't be able to have the illusion of a monster popping out of the screen to bite your head off with this.

Its a start, and holographic tech is on the rise... not long till we have our holodecks Smile
