APPLICATIONS OF 3D TV

In the world of television, content is king but in 3D land it's looking more like the court jester.

The first 3D televisions went on sale on Friday, but it will be several months until programming catches up.
                                    
The football World Cup will be beamed to international 3D viewers in June and July, but SBS is yet to finalise its plans. Pay TV network Foxtel has said it will begin test broadcasts next year.

For now, early adopters have to be content with watching 3D movies on Blu-ray or using a converter on some models to regular content to 3D. But the quality is inferior to made-for-3D content, Mark Leathan, head of marketing consumer electronics for Samsung, said.

He predicted 3D sets would account for 10 per cent of television sales over the next year and people who buy now are ''future prepping'' themselves for the content onslaught.

But being first doesn't come cheap. Base model 3D TVs cost $2500, plus $599 for a Blu-ray player. Sony will launch its 3D sets in July, after which Mr Leathan expects prices to drop.

The technology that's supposed to convince me that a 3D image exists when I look at a 2D screen doesn't work for me.

Nor does it work for a small but significant percentage of the population -- 4 percent to 10 percent, depending on which expert you ask. Me, and millions of people like me, are being left behind by content and hardware companies as they move to 3D.

I don't mean to complain. It's not the end of the world. Flat-viewers, like me, can watch 2D versions of 3D content. I saw "Avatar" in the non-3D version. As a bonus, the theater was nearly empty--the 3D showing down the hall was more crowded. Plus, we didn't have to wear those dorky glasses.

Of course, we are social beings, and not being able to view 3D means that group or family outings to 3D showings are awkward for the flat viewers, who may have to sit through a showing that will cause headaches or just look bad to them.
                    
But the flat-viewer's experience with 3D imagery can vary. While I find viewing 3D imagery uncomfortable, Daniel Terdiman, another person at CNET who can't see 3D, saw the 3D version of Avatar and wore the 3D glasses. It looked fine to him, just not 3D.

At CES this year, the trend toward 3D in home television sets was unmissable, but there was no mention by the manufacturers of how this move would affect flat viewers. I was curious how the hardware companies, which fight for every point of market share jealously, could cavalierly ignore the large number of us who won't like this new direction.

Oddly, none of the HDTV manufacturing companies I reached out to could provide a direct comment on this topic, but I did talk with people familiar with the industry and with an optometrist who has a vested interest in promoting the growth of 3D content viewing.

Bruce Berkoff of the LCDTV Association and formerly a marketing executive at LG, noted that for all the hype around 3D, the television manufacturers are not really investing much in putting products on store shelves, nor are they expecting consumers to pay for it yet.

Adding the capability for televisions to display alternating images for stereoscopic viewing through electronic shutter glasses is not expensive. It's the glasses themselves that are, and only a few 3D-capable sets actually come bundled with them. So consumers will be able to soon buy televisions ready for 3D without spending much.

Berkoff, and everyone else I talked to about 3D TV, reminded me that a good 3D TV is also a good 2D TV. You should be able to turn off the 3D display features and view content designed specifically for 3D but in 2D: You just show the view for only one eye. If the refresh rate of the program is high enough, you should not notice much of a difference in picture quality.

From the optometrist's perspective, the inability to process stereoscopic imagery is, for many people, a treatable condition. Dr. Brad Habermehl, president of the College of Optometrists in Vision Development, told me, "You don't have to be a 3D refugee if you get to the root of the problem. The majority of stereo-blind people really can be helped."

Habermehl says that there are methods to teach people to see in 3D. Using graduated methods and physical aids (lenses) as "training wheels," he says, people can eventually learn how to "point both eyes to focus on the same space." It's like riding a bike. Once you learn, the training wheels come off and you can't imagine not doing it. "Vision is definitely learned," he says. "That's what vision training is."

The doctor sounded to me suspiciously like a spokesperson for the 3D television manufacturers, or at least a recipient of some marketing dollars from them. But he's not.

"It would be nice if they would fund us," he said. But after reminding me that "Avatar" had already made $1 billion in box office receipts, he added, "I don't think the industry is worried about this."

Personally, I have no interest in undergoing medical treatment just so I can spend more money on consumer electronics. Although Dr. Oliver Sacks, in a compelling New Yorker article, did make me wonder what my kind is missing.

And regardless of whether you see in 3D or not, the technology is inexorably changing the visual language of movies and television shows. When directors create shows for 3D, they can't rely on cinematic methods viewers are used to in 2D for conveying action, depth, and movement.

Hard cuts and swooping camera moves can disorient viewers new to 3D. The new standard of practice is to lock down the camera and move the action around it, instead of the reverse, which is the case in today's 2D movies. Good 3D movies today will appear subtly more stately and cinematic than 2D shows.

For all the hype at CES, 3D for the next few years is likely to be a "feature" in the new crop of TVs, according to Gary Merson of the HDGuru3D site.

"It's not black-and-white to color," Merson says. "It's a feature, like Internet connectivity and stereo."

He also points out that the content is not there yet, and that many consumers have only recently upgraded their tube televisions to HD flat screens.

For people like me, for whom the world is flat, this feature can not roll out slowly enough.

ABOUT THE GLASSES OF 3D TV



                                          
Makers are blaming disappointing sales of 3-D TVs last year in part on the bulky glasses they came with. They're trying to tackle that this year by introducing sets that work with lighter, cheaper glasses of the kind used in movie theaters.

Manufacturers don't plan to completely supplant the 3-D TVs that require the heavier, battery-powered glasses, which went on sale last year for the first time. But Samsung Electronics Co. estimates 1 million 3-D sets were sold in the U.S in 2010, far short of its initial estimate of 3 million to 4 million, and the introduction of a competing technology a year later is another sign that the first 3-D TVs didn't live up to expectations.

LG Electronics Inc. was the first major TV to announce new 3-D sets Wednesday, a day ahead of the opening of the International Consumer Electronics Show in Las Vegas. LG, a South Korean company, said it will start selling two models, a 47-inch and a 65-inch one, later this year that use the lighter, cheaper glasses. Each will include four pairs. Current 3-D sets usually include one or two pairs of the bulkier glasses; some don't include any, requiring consumers to pay about $100 per pair.

"We're meeting consumers' needs by eliminating some of the pain points" by addressing the 3-D glasses issue, said Tim Alessi, director of new product development at LG Electronics USA. "It's going to be the most comfortable viewing experience, just like going to the movies."

Vizio Inc., one of the largest sellers of TVs in the U.S. but not a leader in the high end of the market, which includes 3-D sets, announced in December that it would sell a 65-inch 3-D set with the lighter glasses.

The two types of glasses are called "active" and "passive," and each has its benefits and drawbacks.

Last year's TVs relied on active glasses, which have battery-powered shutters that alternately black out each of the eyes to create the 3-D effect. They worked with some high-end flat-panel TVs with little modification required, but they require periodic charging. They also darken the image and may make it flicker.

The lighter glasses, called passive, are not much different from polarized sunglasses. They don't cause video to flicker, and glasses from any manufacturer will work with sets from another manufacturer, or in movie theaters. They don't block as much light as the active shutters, either. However, they only work with LCD TVs that have an extra layer to the screen, and in LG's implementation, the passive glasses cut the resolution of the image in half.
                                      
Not all major manufacturers are on board with the new screen technology. Panasonic Corp., which along with Samsung pioneered 3-D TVs last year, is sticking to active glasses.

The latest PR blurb from CEA headquarters shows that, in a survey taken of 250 sales associates in retail stores, consumer enthusiasm for 3D is strong, with 50% of customers reporting a positive response to 3D technologies, and only 2% reporting a negative response.

That’s not necessarily good news. Do the math, and you’ll see that 47% of customers had no feelings about 3D TV one way or the other, or didn’t respond. (Or were distracted by their teenagers repeatedly begging Mom and Dad for an iPhone or iPod Touch.)

The CEA report does go on to say that “…While nearly 70 percent of sales associates feel well trained to answer questions about 3D, there is still consumer confusion. According to the retail associates interviewed, roughly half of consumers had some confusion about the technology.” That pretty much covers the 47% who didn’t respond positively or negatively.

And now for the devil in the details! “…For most retail associates, 3D content is pivotal. Nearly 80 percent of the associates interviewed believe sales of 3D technologies will not be strong until more 3D content is available.  Moreover, some of the most frequently asked questions by consumers revolved around the availability of 3D content. “

There’s the rub. 3D may look great in the store, but how much 3D World Cup coverage can you watch before nodding off? (Hey, did you catch Paraguay and Japan fighting to a 0-0 tie?) And there are only a couple of 3D Blu-ray discs out there that haven’t been exclusively linked up to a 3D TV bundle promotion.

DirecTV is taking some steps to solve the problem today, announcing the launch of its 24-hour 3D channel in conjunction with Panasonic at a New York City press event. That’s good news for DirecTV customers, but it’s not much help to cable or Dish Network subscribers who are currently limited to ESPN 3D.

If this seems like déjà vu all over again (apologies to Yogi Berra), it is. Remember the start of the digital TV transition in 1998, when exactly two DTV stations went on the air? (For trivia buffs, they were WRAL (CBS) in Raleigh, NC, and WFAA (ABC) in Dallas-Ft. Worth, TX.)

Set-top boxes cost about two grand. You needed component inputs on your TV that could accept the 1080i signal from the box (good luck with the 720p outputs), plus an antenna, and maybe a preamp, and a bunch of coax, and a compass to tell you where to aim the antenna.

Oh, and yes – you needed HDTV content. But there was very little of it back then, aside from some CBS prime-time programs and the ABC Saturday Night Movie. It wasn’t until four years later (2002) before most of the TV networks were carrying a majority of their evening programs and sports coverage in HD. Can 3D TV manufacturers afford to wait that long?

It’s encouraging that 70% of the sales associates interviewed by CEA felt competent enough to answer questions about 3D. But that’s not the problem, based on my experience last Sunday at Best Buy. Only two out of four 3D TV demos in the store were actually working, and one was located in the worst possible spot for a demo. The other had only one pair of working 3D glasses. How do you answer questions about 3D, when customers can’t even see a demonstration of it?

This is where a company like Sony has a leg up with their Sony Style company stores. They can ensure (and they’d better!) that potential customers get the best possible 3D demo, with a large screen LCD TV and comfortable seats positioned at the correct viewing distance. And they can put together a nice mix of live 3D (Sony is a World Cup sponsor) and clips from Sony Pictures 3D movies (think Cloudy with a Chance of Meatballs).

Samsung’s ‘experience’ store in the Time-Warner Center in New York City is also an excellent place to demo 3D. (Hmmm. Maybe Samsung should be thinking about opening their own company stores!) Alas, Panasonic has no such showcase and is at the mercy of Best Buy and Sears. And Mitsubishi (who has some of the most compelling 3D TV value propositions right now) has no 3D showcases at all. (Too bad they can’t just truck their June NYC line show around the country!)
