HDTV Almanac - CES 2010: Do We Need 3DTV Content?
by Alfred Poor on January 8, 2010 Category: General Interest

As I mentioned yesterday, we will need a sufficient quantity of 3D content in order for 3D channels and 3D television sales to succeed, but only a limited amount is available at this point. But maybe that’s not the obstacle that it would appear to be.

At the press conferences at CES on Wednesday, two companies — Toshiba and Samsung – both announced that they will be shipping LCD TVs this year that will be able to convert standard 2D content to 3D on the fly “in real time”. While there are certainly plenty of visual cues that provide depth information in a 2D image, it still takes a lot of processing power and sophisticated computing algorithms to do the job. Is it practical to expect that a television controller can do an adequate job of this complex task?

Well, yesterday I went to find out for myself. I went to both the Toshiba and Samsung booths to view the converted 2D content first hand. And I’m surprised to report that my skepticism was erased by what I saw. In both cases, the 3D effects made a noticeable difference on the 2D source content. The depth effects were not overdone, and at no time did any part of the image extend out “in front” of the screen (minus-Z in 3D parlance), which resulted in a very attractive and watchable image.

This is a critical time for 3DTV. If companies come out with sets that produce images that don’t look good, it could slow the adoption rate severely. A poor job of converting 2D to 3D in real time could be worse for the industry than no conversion at all. But in both cases, the demonstrations looked really good to me. In fact, I would prefer to watch the content in the “simulated” 3D than in the original 2D, because it somehow looked more natural.

The real time conversion of 2D to 3D content has enormnous implications for the 3DTV market, as it could remove the absence of 3D content as a barrier to adoption. And I might be buying a 3D-capable TV a lot sooner than I have been planning to this point.

My own personal feeling is that 3D TV is going to be the next big flop.

(1) You must wear the special glasses.

(2) We're still recovering from the worst recession and at best, 3D sales will be so so.

(3) There's still limited programming....

Alfred,

thanks a lot for sharing your experience! This may be the best news of all in the 3D arena, for this show. Like yourself, I considered the paucity of 3-D content to be the Achilles heel, and wondered if they weren't jumping the gun. I don't expect there will be any significant quantity of "real" 3-D to justify these sets for at least another year, if not longer.

However, the ability to convert 2D to 3D, especially dynamically, in real-time, sidesteps that problem neatly and makes 3D sets viable immediately. I'm not really surprised that it's possible to do so, considering what todays GPU chips are capable of. Taking one HD image, and doing shift and scaling ops to create 2 separate stereoscopic images isn't overly difficult, and exposes the latent dimensionality inherent in the 2D source material. I.e., it triggers those receptors in the brain that perceive "depth".

What I am a bit surprised about though...

3D, with the glasses, wasn't exactly a big hit in the 50's either. It's a gimmic that people will tire of really fast. I had a computer game with 3D LCD glasses and it made me sick after 30 minutes.

I'll wait until they have perfected (and cheapend) laser holography......

Mr. Poor - -

Please share your opinions as to in what ways this "3D" will or might be affected w/ the coming Bandwidth limitations?

{IF downloads, etc., as opposed to only cable connections become involved, etc..}

Thanks!

This is the worst idea since color filters were marketed to turn black and white TV into color TV. Just like that horrible idea, turning a 2D picture into a 3D picture would involve assumptions about what was on the screen. If it's at the top it's far away. If it's at the bottom it must be close. Combine this with some assumptions based on relative motions and you're guaranteed to get an unwatchable mess much worse that the original 2D. But no doubt some people will buy it, use it once and then we'll be reading about how the public was ripped off.

More formally, the second law of thermodynamics says:

In any closed system, the entropy of the system will either remain constant or increase. QED...
