Broadcast Engineering on 3-D

 John Honeycutt, executive vice president and head of international business operations for Discovery International, described the Panasonic AG-3DA1 3-D camcorder as a tool to be used extensively (and cost-effectively). He also called a new concept camera from Sony “the future.”
From the vendors selling 3-D equipment to buyers on the fast track to purchase it, NAB came back to life this year after last year’s economic meltdown. Whether 3-D succeeds in the long term or not, major broadcasters are fearful of being left behind.
One example is Turner Broadcasting, who is “moving full speed ahead” on 3-D technology, said Ron Tarasoff, Turner’s vice president of broadcast technology and engineering. He said Turner sees 3-D as a viable way of transmitting TV in the future.
Today, most of Turner’s work involves equipment testing as the 3-D standards bodies consider setting future standards. “There are many different possibilities in how you produce and distribute content in 3-D,” Tarasoff said. “We need to look very carefully at what will help us with 3-D delivery. We’re almost at the same point we were many years ago with HD. There’s this big push toward 3-D, and there’s very little 3-D equipment out there. There are still many different possibilities in how you produce and distribute content in 3-D.”
Also checking out 3-D gear was ESPN, who is committed to airing 85 events this year. Kevin Stolworthy, the network’s senior vice president of technology, said that at NAB he was looking for vendors with whom he was not familiar. “We think there’s going to be a lot more people out there with new 3-D equipment, software and production tools,” he said.

There is a bit of a joke starting to circulate through the press gatherings and cocktail parties at this NAB convention where everything is supposed to be about 3-D. While we all knew that professional 3-D screens almost universally are designed to work with cheap polarized lens glasses (the kind you get in movie theaters), it is starting to become apparent that the home sets will require much more expensive active shutter glasses. In addition, each manufacturer is making them proprietary to their own systems. So if you own a Sony home 3-D set, you cannot take your glasses over to a neighbor’s house and use them with their Panasonic or Samsung set to watch the Big Game. Sure, they all have flicker lenses, but the triggering mechanism each uses is different. So unless you are willing to shell out in the range of $150 for another pair of fancy specs, watching 3-D in the home will really mean watching 3-D only in your home. Read the rest of this entry »

 HDI plans to show its laser-driven 100in 3-D TV at NAB 2010.
Arriving in Las Vegas, I was somewhat disappointed not to see the halls of the Convention Center floating above the desert skyline like the Hallelujah Mountains in Avatar. The preshow hype of “This is the year of 3-D” has become a mantra for NAB 2010 with the hope of revitalizing equipment providers’ bottom lines with a rush into home-delivered 3-D as powerful as the HDTV onslaught. Maybe, maybe not. Read the rest of this entry »

 XpanD, a European manufacturer that makes active-shutter glasses for movie theaters, as well as 3-D glasses for Panasonic and Vizio TV sets, is developing universal glasses that will work across manufacturer lines.
One of the negatives of 3-D TV is that viewers must always wear special glasses to view the three-dimensional effect. But one “gotcha” that most viewers don’t know yet is that virtually all of the glasses being packaged with early 3-D TV sets are proprietary to the manufacturer’s brand.
That means 3-D glasses sold by Samsung won’t work with Panasonic, Sony or other set brands. Forget bringing your 3-D glasses to a viewing party for a sporting event at the home of a friend using a different kind of 3-D display.
The cheap, polarized spectacles required to view 3-D in movie theaters won’t work at home, either. Most of the new 3-D receivers require “active-shutter” glasses that have to electronically synchronize with the TV set.

 ESPN will produce both 2-D and 3-D broadcasts of the 2010 World Cup events with a single mobile production vehicle on-site in South Africa.
ESPN has been making some big promises about bringing to home viewers a minimum of 85 sporting events in 3-D over the next year. Those programs will launch on the fledgling ESPN 3D network on June 11 with a World Cup soccer match between South Africa and Mexico. The network said it eventually will air 25 World Cup matches, Summer X Games, college basketball and football and the BCS National Championship game.
In the meantime, ESPN’s production staff is learning how to produce -3D programming in the most efficient and cost-effective way. It’s a lesson that many will be watching and ultimately benefiting from. Read the rest of this entry »

 When viewing movies, most less than two hours in length, binocular dysphoria has not been a huge issue for audiences.
Most 3-D display technology, whether in the theater or at home, requires viewers to wear electronic glasses that are timed to open and close rapidly. A slightly different image is projected to each eye, and from that difference, the brain creates the illusion of depth.
However, our brains process visual information in many different ways, and human depth perception is a very complicated business. The brain uses 10 different cues to figure out the distance of an object. One if them is parallax, which is used by most 3-D TVs. For 3-D to work, the brain must reject several of the other cues in favor of parallax. Read the rest of this entry »

 Aside from its new 3-D TV sets, Sunny Ocean Studios claims it can retrofit regular displays for 3-D and also assist in 2-D-to-3-D image conversion.
Following predictions at this year’s CES that it would take many years to create affordable 3-D video displays without glasses, Sunny Ocean Studios of Singapore has introduced a 27inch 3-D HDTV offering 64 viewing angles without glasses.
A serious upgrade from eight or nine viewing angles and lenticular displays shown at CES, Sunny Ocean Studios claims it can retrofit regular displays for 3-D and also assist in 2-D-to-3-D image conversion. Where most companies offer stereoscopic 3-D, which uses glasses, Sunny Ocean is pushing auto-stereoscopic, which is glasses-free 3-D.
“We are presenting a solution where the image appears to float spatially in front of the screen without the help of the usual aids like 3-D glasses,” said Armin Grasnick, founder and managing director of Sunny Ocean Studios. Read the rest of this entry »
