Roger and I happened to shoot the above video in the Samsung booth at CES 2010, but it could have just as easily been in any number of booths from a number of manufacturers. What is impressive is how quickly the component ecosystem is coming together. Panasonic was showing 3D (dual lenses, with sensors spaced about average the size of eyeballs), digital camcorders for a relatively reasonable $21,000; this is amazing as it is well down the cost curve, as compared to HD cameras when HD launched.

I was surprised at the quality of the video especially because the television rendered the video from two to three dimensions. This is truly amazing; as the implication is the bandwidth of the signal to the TV is no different for 3D, since it is in its native 2D format. We also looked at video created originally for 3D, which is the optimal content format as it is the highest quality.

Conversations with various folks from the floor and from the Parks Associates Connections Conference, suggest that the bandwidth considerations will not be two times what is required for 3D, because much of the difference signal can be computed from the original. A higher quality signal is required; however, so encoding bit rates may increase a bit. The other factor playing in the early adoption of 3DTV is the fact that, according to Kurt Scherf of Parks Associates, there are at least 3 million capable 3D television sets deployed today by people who may not even realize their sets have this cool new feature waiting to be unleashed.

With the announcements from ESPN, Discovery and DirecTV regarding distribution of 3D, the support of 3D on BluRay and the momentum gained from movies like Avatar, 2010 should be the year of 3DTV, right?

Whoa, hold your early adoption horses, we have a chasm to cross…..

Sure, the images look great on the tradeshow floor and the device ecosystem seems to be coming together very nicely, but are we looking at a market where the products are a bit ahead of the mainstream consumer?  In reality, 2010 is probably not the year of 3DTV, but maybe it will be remembered as the year that 3DTV was hyped.  There are a number of reasons to be skeptical of the hype and Howard Postley of 3ALITY Digital Productions provides enlightening insight in this video interview shot at Parks Associates Connections Conference at CES. 

As producers of equipment that allow the creation of 3D content, Postley and 3ALITY Digital have taken the proverbial arrows in the back regarding 3D TV content production.  Producing for 3D is a new art and requires looking at things (literally) differently as compared to 2D productions.  Postley explains that the live 3D production for television has required two film production crews, which increases cost of production. 

He also explained that things such as closed captioning and graphics are other challenges that need be dealt with, so that a character zooming across the room doesn’t result in graphics and closed captioning to disappear behind a person’s head.  The MPEG IF is addressing these sorts of technical details. 

Like VOD in its early days, content rights, particularly for content produced in two dimensions, may be an issue, at least for older programs.  Granted, content owners have gotten more sophisticated in their contracts (rights to everywhere in this and every other universe).  Still, there may be talent who has not assigned their 3D rights to a particular content owner. 

The human factors associated with the need for glasses will be probably the biggest determinant in the near-term success of 3DTV.  People may wear glasses for special events and for big productions, but how often will they wear them for everyday television?  The passive glasses don’t work for everyone and the auto-shutter glasses, which have the potential to be tuned to the person, were light enough, but did feel like I was wearing glasses again; I spent decades trying to ditch my glasses, I certainly don’t want to start wearing glasses again for long periods of time again. 

The ideal would be an autostereoscopic display, as glasses would not be required.  Although there were some demonstrations of audostereoscopic displays at CES, the experts on the Connections Conference at CES seemed to agree that is still 5 to 10 years before autostereoscopic technology makes its way to the living room.  They suggest that the first implementations of autostereoscopic displays may be include hand-held devices and digital signage applications. 

The way we interact with television also factors into the success equation of 3D TV.  For instance, right now, I am composing this post on my lap-top, while watching the NFL playoffs on the television.  If I were wearing 3D glasses to watch the football game, would I have to remove them every time I glanced down at the PC? 

This leads me back to my original question – the Navin White question – about eyestrain and other potential long-term health effects of 3D TV. I tend to get queasy after playing video games involving motion, such as flight simulation games.  Will I feel similar watching a full auto race in 3D?   There are others who have similar concerns regarding the potential for 3D to have negative health effects, including David Wood, deputy director general of the European Broadcasting Union, who is referenced in this article, 3D TV, a sight for sore eyes. 

Make no mistake, 3D TV will be here eventually, it just that 3D TV has the same feel that HDTV or VOD had 10 years ago, when there was a lot of hype and most of the elements in place, but some seemingly small details held up widespread deployment for a number of years.
