CNET’s guide to 3D TV: What you (still) need to know

3D TV may be a flop in many ways, but there’s no doubt it’s here to stay as a feature on many higher-end TVs. If you’re curious about 3D, here’s the place to find out more.

by David Katzmaier

What is 3D TV?

When we say “a 3D TV” what we mean is “an HDTV with 3D compatibility.” 3D compatibility is a feature on higher-end LED LCD and plasma TVs released since 2010. It allows those TVs to display specialized, made-in-3D video with the right accessories — namely 3D glasses and a 3D source device. With that in mind, here are a few basic points about 3D TV.

All 3D TVs are first and foremost 2D TVs

All 3D TVs will display current 2D high-def and standard-def content with no problem and no glasses required. In fact, for the foreseeable future we expect most 3D TVs to spend the vast majority of their time showing the same 2D video delivered by other HDTVs.

Moreover, the 2D picture quality of 3D TVs is not affected in any negative way we’ve noticed by their 3D capabilities.

That’s why we prefer to think of 3D compatibility as “just another feature,” like Internet streaming or a fancy remote control. You can take it or leave it, but for most TV shoppers it’s not the most important feature on a modern television.

Here’s an example of what 3D looks like without glasses. Notice the doubling of onscreen objects.Sarah Tew/CNET

How 3D TV works
A screen showing 3D content displays two separate images of the same scene simultaneously, one intended for the viewer’s right eye and one for the left eye. When viewed without the aid of 3D glasses, the two full-size images appear intermixed with one another, fuzzy and basically unwatchable. When viewers don the glasses, they perceive these two images as a single 3D image, a process known as “fusing.” The system relies on a phenomenon of visual perception called stereopsis, so it’s not “true” 3D like real life or a hologram.

3D content is also different from standard HD content in a few important ways. For a primer on that, check out “How 3D content works: Blu-ray vs. broadcast.”

To view 3D on a 3D TV, you need 3D glasses, a 3D source device, and 3D video content

Despite the launch of glasses-free 3D products like the Nintendo 3DS and certain phones and laptops — and breathless reports by bloggers — we think an affordable, practical 3D TV that doesn’t require glasses is at least five years away. For now, every viewer of a 3D TV needs to wear a pair of special glasses to see the 3D effect.

                                                              3D glasses are designed to fit over standard glasses.Sarah Tew/CNET

In addition to a new TV and glasses, you’ll also need a 3D source, typically a 3D-capable Blu-ray player or cable/satellite/Internet video box. You’ll also need the 3D version of the Blu-ray disc, or be watching a 3D program on a 3D channel or streaming service. (While most 3D TVs offer 2D-to-3D conversion, the process isn’t really good enough to compete with native 3D content.)

New 3D TVs have 3D quality comparable to a theater
3D TVs released since 2010 can display high-resolution, color-correct 3D images, which blows away the old “anaglyph” method using red-and-blue filtered glasses. The biggest differences between theatrical 3D and 3D TV in the home are the size of the screen and the distance you sit from it. If you enjoy 3D theatrical presentations, you’re a prime candidate for caring about 3D in the home.

Not everyone can see 3D, and sometimes 3D causes discomfort
Between 5 percent and 10 percent of Americans suffer from “stereo blindness.” They often have good depth perception — which relies on more than just stereopsis — but cannot perceive the depth dimension of 3D video presentations.

Warnings like this one from LG are a little alarmist, but comfort during 3D viewing is a legitimate concern.Sarah Tew/CNET

By the same token, some 3D presentations can cause eye fatigue, headaches, or other discomfort in some viewers, particularly over long periods of time. In CNET’s experience, and in the opinions of most experts we’ve consulted, the main cause of eye fatigue isn’t the 3D technology itself — it’s badly produced 3D content. That said, you’ll still need to give yourself a few minutes to get used to the effect, which can seem jarring at first. Check out “Don’t sit too close to the (3D) TV” for more on how 3D can affect viewers.

Active vs. passive 3D TVs

There are two types of 3D TVs on the market today: active and passive. Both will work with any source — there’s no such thing as “active” or “passive” 3D Blu-ray players, for example — but they produce the 3D effect in distinctly different ways.

Active 3D was first widely introduced in 2010 by most TV makers, while passive 3D widely debuted in 2011. The main difference is in the glasses: active glasses use liquid crystal shutters that run on batteries, while passive glasses use simple polarizing lenses, similar to what you’ll get in most U.S. 3D theaters. You’ll hear a lot of claims about each if you’re comparing 3D-compatible TVs, so here’s what you need to know.

3D technology varies by brand and TV display type
In 2013 LG, Vizio and Toshiba are in the passive camp, while Samsung is exclusively active. Sony sells mostly passive, while Panasonic offers passive LCDs and active plasmas.

Active 3D is starting to become less popular with TV makers than it was in the last couple of years, but with Samsung’s strong support it isn’t going anywhere soon. LG is the main developer of the “pattern retarder” technology used by all current passive sets.

It’s also worth remembering that while an LED LCD TV can be either active or passive, plasma TVs can only be active.

Active and passive 3D TVs have similar pricing, but passive 3D glasses are cheaper
The main market advantage of passive 3D TV is inexpensive glasses. Most passive 3D TVs come with at least four pairs of passive glasses today, and some even more. In a new development for 2013, most active 3D TVs include glasses by default, too — usually two but sometimes four pair as well.

                                                                                                     Samsung’s $20 active 3D glasses

Bought individually, active 3D glasses start at $20 for Samsung’s models and go up from there. Very recent-vintage active 3D TVs that comply with the universal full HD 3D standard work with any active glasses that also comply, including those cheaper Samsung’s. Older active 3D TVs typically require the same brand of glasses (2011 Panasonic TVs need 2011 Panasonic 3D glasses, for example) or more expensive universal glasses.

Extra passive glasses cost $5 to $20 each from TV makers, and you can get them cheaper from third parties and/or in packs of four or more. You can use pretty much any circular polarized passive glasses — including off-brand versions or even ones “borrowed” from a theater, with any passive 3D TV.

                                                                                  Some passive glasses, like these from Sony, can be pretty sleek.

Passive glasses are easier to use and wear
Since they don’t have electronics or batteries, passive glasses are lighter and more comfortable than most active glasses — although new active glasses are generally lighter than their predecessors, and we’ve found most of them comfortable enough. Passive glasses come in many form factors, including designer and clip-on versions for people who wear regular glasses. They also don’t introduce flicker when you’re multitasking with a laptop, phone, or other screen while wearing them, nor under bright fluorescent lighting.

Active glasses flicker in both circumstances, but in our experience they don’t usually introduce visible flicker when you’re actually watching 3D TV. They do need to be turned on and synced with the TV, although that’s usually a simple process. Their batteries also need to be periodically replaced or recharged, typically via a USB port (below).

Active and passive both have picture quality pros and cons

In our experience, 3D picture quality varies greatly depending on manufacturer, model, glasses, technology type (LED LCD or plasma), and even screen size. That said, we can make some broad generalizations between active and passive based on what we’ve seen.

Passive 3D TVs have a brighter 3D image than active, although active 3D TVs can get bright enough for most viewing environments. Passive generally causes less crosstalk — a major 3D-specific artifact — than active.

Note that even though your eyes together are getting all the pixels from the TV, you can still see these lines depending on how close you sit, and how big the TV is.Geoffrey Morrison/CNET (

Active 3D TVs don’t show jagged-edge artifacts and line structure that can be seen on passive models, although these artifacts are less visible on smaller screens and farther distances. They also keep their 3D effect better when seen from extreme angles to either side or above and below the image — although from most normal viewing angles, passive 3D TVs have no issues maintaining the 3D illusion. The fact that passive isn’t available on plasma TVs is also an issue to home-theater enthusiasts who don’t want to buy an LCD.

We prefer the 3D picture quality of the best active 3D TVs over passive for critical viewing
Our main hangup with passive 3D TV is the presence of the artifacts mentioned above, which we find especially distracting at the closer seating distances and with the large screen sizes favored by home-theater enthusiasts. But with the practical and certain picture quality strengths of passive 3D, especially in bright rooms, an argument can certainly be made that it’s the better choice overall.

Check out “Active 3D vs. passive 3D: What’s better?” for more.

4K TVs with passive 3D potentially represent the best 3D picture quality
The “best of both worlds” would be all of the brightness and ease of passive 3D without the artifacts. That’s what 4K TVs that employ passive 3D promise. Their higher resolution should eliminate most of those jagged edges and line structure. The only passive 3D 4K TV we’ve seen so far is the 84-inch Sony XBR-X900 , which, in limited testing, showed the best 3D TV image we’ve ever seen.

What about 3D content?

You need made-in-3D source material to take full advantage of a 3D TV. Many 3D products feature 2D-to-3D conversion options, but they’re a far cry from a real 3D source. 3D content is still quite rare, and in our opinion that’s the No. 2 obstacle (besides the glasses) preventing 3D TV from quicker adoption.

3D Blu-rays are rare, but they easily provide the best 3D home video experience
A total of just 96 3D Blu-ray discs were released in 2012, according to Blu-ray.com — compared with more than 2,700 2D Blu-ray releases. The 2011 ratios are comparable, and so far in 2013 3D Blu-ray releases are on the same pace as the last two years. In other words, 3D Blu-rays aren’t getting much more common as the format matures.

Many 3D Blu-rays are documentaries, particularly IMAX, or children’s animation titles. There are also quite a few blockbusters; nearly every big-budget 3D theatrical release also makes it to 3D Blu-ray. The 3D Blu-ray format, and made-in-3D movies, definitely represent the state of the 3D art, with full high-def resolution and the benefit of the latest filming techniques to make the 3D effect comfortable and enjoyable.

Actual 3D TV channels are rarer still, and have compromised picture quality
Currently there are only two nationwide 24-7 TV channels that offer 3D content: ESPN 3D and 3net. As we mentioned previously, ESPN has announced that it will pull its 3D channel by the end of 2013. 3net offers primarily documentaries and IMAX. DirecTV and Comcast have exclusive 3D channels, called n3D and Xfinity 3D, that feature niche 3D content, but they’re part time, not 24-7.

Side-by-Side

Unlike Blu-ray, 3D broadcasts on TV currently use a half-resolution 3D format known as side-by-side, resulting in a significantly softer, non-high-def look. We know of no plans to add more 3D channels or introduce a full-HD resolution 3D broadcast. Click here for more on the differences between Blu-ray and broadcast 3D formats.

LG’s “3D World,” found on its Smart 3D TVs, is an example of an on-demand 3D content portal. Even the menu is in 3D, hence the blurry look here.Sarah Tew/CNET

Other sources of 3D content include VOD, special events, streaming services, and video games
Most pay TV providers, including DirecTV, Comcast, Time Warner Cable, and Verizon Fios, offer 3D pay-per-view/video-on-demand movies and select special events, for example the 2012 Summer Olympics . The Vudu streaming service also has a smattering of 3D movies available. Some 3D TV makers, namely Samsung, LG, and Sony, have also launched 3D pay-per-view streaming services built into their Internet TVs, although content is very limited at the moment. Sensio’s 3DGo app, currently only available on Vizio TVs, promises more content than other comparable services.

If few people own 3D TVs, content producers have little incentive to deliver 3D programming and games. But lack of 3D content is a big reason people don’t want to get a 3D TV today. We don’t see this situation changing in the immediate future, and we feel glasses-free 3D TVs need to be available at mainstream prices — and work well — before 3D content has a chance to become as common as 2D high-def content is today.

 

CNET’s 3D recommendations

How should 3D shape your TV buying decision? Not strongly, in our opinion. Here are few things to keep in mind.

The best way to think about 3D is as ‘just another feature’
Manufacturers construct their product lines to get you to pay more for “step-up” features. 3D is just that, just like Smart TV, a nicer remote, or fancy improvements to picture quality. They’re generally all tied together, too, which is why nearly all high-end TVs — and many midrange ones — now feature 3D compatibility. At CNET we tend to focus on midrange and flagship models, and among the 55 TVs we reviewed in 2012, 27 were 3D compatible.

2D-only TVs usually have worse 2D picture quality than 3D-compatible TVs
If you “boycott” 3D by restricting your search to 2D-only televisions, you’re missing out on the TVs with the best 2D picture quality. In our experience, the best-performing 2D TVs happen to have the 3D feature as well. If you’re willing to pay extra for an improvement in 2D picture quality, chances are you’ll be getting 3D whether you like it or not. That said, just because you buy a 3D TV — even just to get the best 2D picture quality — doesn’t mean you need to ever use the 3D feature.

Don’t buy a 3D TV just to stave off obsolescence
If the only reason you’re considering stepping up to the 3D feature is to avoid buyer’s remorse in the next couple of years, in anticipation of 3D content becoming widespread, you should stick with a 2D TV. For reasons discussed in the content section, we don’t see 3D as a “must-have” for most TV buyers, either now or in the near future.

Toshiba's glasses-free 3D TV uses lenses to direct light to in separate left and right channels across nine different angles so 3D video can be seen from different vantage points.

3D Printer

Posted by admin | 3D Printing,3D Tech | Wednesday 20 July 2011 19:40

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.

3D Film

Posted by admin | 3D Film,3D Tech | Thursday 14 July 2011 21:59

There are two type of transparent film, which allows to display stereoscopic 3D image on any screen, such as laptop, monitor, or television. Read more about GlobalWave Pic3D film here.

There are two distinguished methods presently available on the market: parallax barrier and lenticular film. The difference between those two is self-explanatory as shown below:

 

Lenticular screens

Screens with a molded lenticular surface are frequently used with projection television systems. In this case, the purpose of the lenses is to focus more of the

light into a horizontal beam and allow less of the light to escape above and below the plane of the viewer. In this way, the apparent brightness of the image is increased.

Ordinary front-projection screens can also be described as lenticular. In this case, rather than transparent lenses, the shapes formed are tiny curved reflectors.

RealD Launches First 3D Stereoscopic Converter ‘PODs’

RealD Pro, the world’s most trusted 3D visualization source for industrial applications, has introduced the first3D stereoscopic converter PODs. The PODs present a simple conversion solution when upgrading to a new stereoscopic display monitor, such as a DLP or XPOL HDTV.

The PODs automatically detect the output format from a connected display device and convert most stereo-enabled software applications from native stereoscopic output format to the required format for stereo viewing on the display monitor. The RealD converter POD provides an immediate, affordable replacement option for CRT or LCD monitor users. When combined with DLP TV kits available from RealD Pro, the user simply plugs the source data into the input port on the POD via an HDMI cable and the output HDMI cable into the 3D-ready HD TV.

RealD Side-by-Side 3D-POD

3D Converter:

  • The 3D converter PODs are designed specifically for research and development environments, where 3D visualization is heavily used and where departments or organizations are seeking alternatives to CRT display technology for stereoscopic applications.
  • Industries include government and defense, entertainment, oil and gas, education, design and development, and medical.
  • The RealD 3D-PODs make this transition fast, easy, and inexpensive.
  • The 3D-PODs also enable development teams to more easily present their work in front of customers or senior management, providing greater collaboration, improving productivity, reducing prototype expenses and accelerating time to market.

The three PODs include dual input to checkerboard, side-by-side to horizontal interlace or checkerboard, and page-flip to checkerboard:

Dual Input POD – a flexible dual stream video format conversion system that converts a dual stream of data, such as one intended for a dual projector installation, into a checkerboard output for visualization in stereo on 3D DLP or plasma systems. It can also produce the simultaneous independent video streams used by RealD’s new CrystalEyes 5 active eyewear. This POD also supports side-by-side conversion when using just a single input. (MSRP $2000)

Side-by-Side (SBS) 3D-POD – receives and transmits a single HDMI compatible audio / video signal. When the content is received in RealD SBS format, it is automatically converted into either checkerboard or horizontal interlace format, depending on the connected display device. (MSRP $500)

Page Flip 3D-POD – converts a page-flip (frame sequential) stereo output to a checkerboard format for display on a DLP TV. This POD is ideal for stereoscopic software applications formerly used with CRTs. The Pod functions as an “HDMI Repeater,” as defined in the HDMI version 1.3a standard at up to 1080p@60Hz, and complies with the HDCP security protocol. (MSRP $500)

Bring Home 3D Technology Today

(by abt.com)

From the advent of moving pictures to the invention of TV, historic developments drove image technologies through the 20th century. Among them, color and high definition (HD) were two major advances. Now, we present a third breakthrough in the form of full HD 3D. This new viewing experience is creating a new dimension of video realism. 3D is great in the theater; bring the same amazing technology home today. Don’t get stuck in 2D when you can bring 3D right to your living room. 3D is the latest dimension in gaming, movies, and TV programming. Don’t watch TV, live it. The amazing images jump off the screen, bringing the action so close, you can almost feel it.

What Does 3D Mean?
3D images are a made with a special camera that records one image from two perspectives. One of the images is recorded and projected for the viewer’s right eye and the other image for the left. When 3D glasses are worn, an illusion of depth as well as the image’s height and width is created. If you look at the images without the assistance of 3D glasses, the image will appear blurry.

  • The only way to immerse yourself in 3D is to have a 3D TV.
  • A 3D TV isn’t the only component you will need to bring your TV to life.
  • You will need a 3D Blu-ray player, 3D Glasses and HDMI 1.4 cables.
  • If you love to play video games, think of a Sony Playstation 3.
  • You will be able to watch Blu-ray and 3D Blu-ray DVDs as well as play games in 3D.

3D Compatible TV

3D has been around for decades, only now can you get a movie-quality 3D experience at home. A 3D TV can have an LED, LCD, or plasma screen. The only difference from a 2D TV is the screen is designed to show two versions of the same image. This works because the two versions are alternated at speeds that are so fast, they are undetectable by the human eye.

Three Types of 3D TVs
There is a 3D TV for everyone. Because 3D technology is so new, manufacturers are giving consumers options.

3D-Ready
Most TVs are 3D-ready. What does that mean? The TV will be equipped with a 3D emitter to send signals to the 3D glasses that you will be wearing. These TVs usually do not come with 3D glasses.

3D-Capable
These TVs are made with the screens that can play a 3D image, but they lack the emitter that is necessary to project a 3D image. 3D emitters are available to purchase for these TVs and they are external additions to the TV.

Full 3D
Similar to 3D-ready TVs, these sets are equipped with 3D emitters and the proper screen to produce a 3D image. They will usually come with 3D glasses.

Choose from:


LCD

LED

Plasma

3D Compatible Blu-ray Player or Playstation 3 (PS3)

The PS3 will be 3D compatible through a firmware upgrade sometime in 2010.

It means you can watch 3D Blu-ray DVDs and play games in 3D after downloading a firmware upgrade.

3D Glasses

Until recently, 3D glasses were plastic with one red lens and one blue. Improvements have been made on the technology; consequently the new 3D movies, TV broadcasts, and games can be viewed in 1080p, full 3D HD.

Active Liquid Crystal Shutter Glasses
Active liquid crystal shutter glasses replace older tinted glasses to give a 1080p, full 3DHD image. Each lens alternates blocking each eye up to 120 times per second, like opening and closing a shutter, one side at a time. They link to the TV by an infrared Bluetooth signal and most use rechargeable batteries.

3D Content

3D movies and animated cartoons are available on 3D Blu-ray DVDs. More than movies will be available in 3D.

Both ESPN and the Discovery Channel are developing channels devoted to 3D. ESPN channel is slated to begin in June 2010 and the Discovery Channel late 2010/ early 2011.

PS3 will also have games available in 3D with the option to be played in 2D.

HOW 3D TV WORKS

3D or stereoscopic imaging is a technique capable of recording three dimensional images, which gives the illusion of image depth. 3D TV technology encompasses TV programming, movies, or games. Stereopsis is the process which allows our individual eyes to see depth in an image. One of the images is projected for the viewer’s right eye and the other image for the left. When the two images are displayed they are layered one on top of the other; one is slightly to the right and one is slightly to the left. When looking at the images without the assistance of 3D glasses, the image will appear blurry. When wearing 3D glasses, the images blend together and give the illusion of depth as well as the image’s height and width. 3D is filmed using two cameras in 1920 X 1080 full HD. When both sets of recordings are played at the same time and overlapped, an illusion of depth is created. When you wear 3D glasses, images recorded this way will jump off the screen.

YOU NEED TO KNOW

When purchasing 3D technology for the home, it is very important to note that all brands are not compatible with each other. Buying a 3D compatible Sony TV with a 3D compatible Samsung Blu-ray player will not work correctly.

*Please note that all 3D technology will work with 2D television broadcasts and Blu-ray media that you enjoy today.

Frequently Asked Questions:

 

Q: Do I need to buy a 3D TV to watch 3D programming, movies, or play games?
A: Yes. Currently none of the traditional standard or high-definition TVs on the market can be upgraded to support the new 3D technology. You will need to buy a TV specifically made for viewing 3D TV broadcasts, movies, or playing games. There are a few 3D-compatible DLP and Plasma TVs which have been recently released by Samsung. There is no confirmation by Samsung as to whether they will be compatible with other manufacturer’s 3D sources, like 3D Blu-ray players. Mitsubishi also has a 3D adapter box available sometime in 2010, which will be compatible with sources like Blu-ray players. The image quality post 3D upgrade is in question.

Q: Can everyone see 3D?
A: No. According to the College of Optometrists, approximately 5-10% of the population has stereo blindness. That segment of the population can’t see 3D images. If you have stereo blindness you can still watch 3D programming, unfortunately, it will only be perceived in 2D. If you have stereo blindness and watch 3D you may experience headaches and/or your eyes could feel tired.

Q: Will I get a headache?
A: Most people will not get headaches or eyestrain from watching 3D programming. 3D programming can cause headaches or strain after extended periods of watching. You eyes could feel tired.

Q: Do I Have to Wear the 3D Glasses?
A: Yes. If you watch without the glasses then you will see a blurry, unwatchable image. All who watch 3D must wear the 3D eye wear.

Q: What equipment will I need to buy in addition to a 3D TV?
A: For watching TV, a pair of active liquid crystal shutter glasses will be needed. Also, if you would like to watch Blu-ray movies, you will need to purchase 3D compatible equipment. A standard Blu-ray player will not play 3D Blu-rays. You will need a 3D Blu-ray player to se 3D images.The stand alone exception is Sony’s Playstation 3. By the end of 2010 Sony will release a firmware upgrade allowing users to play 3D Blu-ray discs and games in 3D.

Q: Is a 3D Movie in the Theater the Same as a 3D Movie at Home?
A: The technology is similar with two major differences, the size of the screen projecting the images and the glasses. In the theater the images are very large and don’t require the same active liquid crystal shutter glasses that you need in a home setting. It’s necessary to sit closer to the TV than you would to a screen in a theater.

Leonar3Do: Virtual Reality in 3D

Leonar3Do – The 3D Virtual Reality Kit

The first time you wear your Lenoar3Do 3D glasses and hold the bird in your hand that functions as a 3D mouse, you will have a feeling of wonder such as when a person first drives a car and feels control over the power of the engine. With Leonar3Do, you are able to control how you move within space: you can create and pull objects ‘out’ from the monitor with the cursor. As with the car, the experience is real: the control is yours, you have power over space. This alone is a unique experience, but with Leonar3Do you are capable of much more.

 Main components of the Leonar3Do Interactive Desktop VR (virtual reality) hardware:

  • A spatial input device (the ‘bird’), 3D glasses and monitor-mounted sensors.
  • The ‘bird’ operates in six degrees of freedom, which means that you can not only move any objects or the whole virtual space, but also you can rotate them.
  • 3D glasses allow users to perceive a stereoscopic image being displayed in a free air as a 3D object.
  • Visual sensors continuously track positions of both, the ‘bird’ and the glasses.
  • Application  software generates, manages, and displays virtual reality.
  • Users, even a 10-12-year-old, can create their own virtual world in space right in front of 3D monitor: they can also design in a free air, create models and parts, make new toys, design and play their own games, construct buildings using library of shapes, and much more, – all,which had been only dreamed of in the world of science fiction.

(PhysOrg.com) — Critics of 3D viewing may call the technology a passing fad, but if engineers can overcome some of the challenges of today’s 3D systems, 3D TV could work its way into becoming a common household product. There are several different ways to create 3D images on a display, and each has its own advantages and disadvantages. In one of the latest approaches, researchers from Japan have developed an integral 3D TV system based on the 100-year-old technique of integral photography that uses large numbers of lenses and pixels to transform ordinary photographs into 3D video.

The engineers, from NHK (the Japan Broadcasting Corporation) in Tokyo and JVC Kenwood Holdings, Inc., in Kanagawa, have been developing and improving their integral 3D TV system for the last several years. Their most recent system will be published in an upcoming issue of The Journal of Display Technology.

One advantage of the integral 3D method is that, since it relies on a large lens array (400 lenses in the horizontal direction and 250 in the vertical direction), it doesn’t require viewers to wear glasses and offers more viewing flexibility.”

“The greatest advantage of our system is its suitability for the broadcasting system, i.e., glasses-free display, full-parallax (viewers can enjoy 3D images from any posture) and real-time motion imaging,” Jun Arai of NHK told PhysOrg.com.

Integral 3D TV system projects a promising future (w/ Video)

The experimental setup for (a) capturing video and (b) displaying video. Both steps involve a large array of convex lenses to generate a 3D effect. Image credit: Arai, et al. (c)2010 IEEE.To record images, a large array of many convex lenses is placed in front of a Super Hi-Vision camera, which records the direction and intensity of light as viewed from slightly different directions. To display the images to a viewer, a Super Hi-Vision projector projects the images onto a diffusion screen, in front of which is an identical convex lens array. This set-up can recreate the direction and intensity of the light that was originally recorded. Since each lens looks slightly different at different viewing angles, the images look slightly different from different directions, giving a 3D impression.In terms of the image characteristics, there is a trade-off in the system in which an increase in the viewing angle results in a decrease in the image resolution. To maximize both characteristics, the researchers explain that it is necessary to shorten the distance between the lens array and the display device, and also narrow the pitch of the lenses, which requires a large number of pixels. Overall, the system uses a total of 7,680 pixels in the horizontal direction and 4,320 pixels in the vertical direction. With these adjustments, the researchers could ensure a viewing angle of 24 degrees and a spatial frequency that is 2.4 times higher than that of their previous system. Arai added that it should be possible to further improve both the viewing angle and image resolution with future research.

3-D movies via Internet and satellite

August 26, 2010

With MVC, the two images needed for the 3-D effect are packed together to reduce the movie’s bit rate.

Multiview video coding (MVC) is the new standard for 3-D movie compression. While reducing the data significantly, MVC allows at the same time providing full high-resolution quality. At the International Broadcasting Convention in Amsterdam from Sept. 10-14, 2010, researchers will showcase how 3-D movies can be transmitted via Internet and digital television channels such as via satellite.

Blockbusters like Avatar, UP or Toy Story 3 will bring the 3-D into home living rooms, televisions and computers. There are already displays available and the new Blu-Ray players can already play 3-dimensional movies based on MVC. The first soccer games were recorded stereoscopically at the Football World Championships in South Africa. What is missing is an efficient form of transmission.

The problem is the data rate required by the movies – in spite of fast Internet and sat-ellite links. 3-D movies have higher data rate requirements than 2-dimensional movies since at least two images are needed for the spatial representation. This means that a 3-D screen has to show two images – one for the left and one for the right eye.

Researchers at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut, HHI in Berlin, Germany have already come up with a compression technique for movies in particularly HD quality that squeezes movies while maintaining the quality: the H.264/AVC video format. What H.264/AVC is for HD movies, Multiview Video Coding (MVC) is for 3-D movies. The benefit is reducing the data rate used on the transmission channel while maintaining the same high-definition quality.

Videos on the Internet have to load quickly so that the viewer can watch the movies without interruptions. Thomas Schierl is a scientist at the HHI in Berlin and he explains that “MVC packs the two images needed for the stereoscopic 3-D effect so that the bit rate of the movies is significantly reduced.” These 3-D movies are up to 40 percent smaller. Thomas Schierl and his colleagues are working to establish the MVC codec for television transmission over satellites or the Internet. “New TV sets will start off by only playing 3-D movies from the Blu-Ray disc that is now coming into the third dimension. The next step to bring 3-D into living rooms will be made possible via broadcast or IPTV channels running via DSL or cable.”

You will be able to experience 3-dimensional movies in your living room in future without any 3-D glasses because the MVC format has the technical features to code and compress several views. After all, everybody enjoying the movie with you on the sofa has a different viewing angle. That is why they need a separate view – their “own” 3-D movie – for his or her individual seat. MVC compresses all of these views into one compact file or stream and one receiver, one set-top box decodes this information and passes it on to the television.

It will also be possible to play the MVC-coded movies on older televisions and set-top boxes and Thomas Schierl tells us how: »The first view corresponds to the signal that the existing television can receive and we would hide the second view in the same stream so that only the new receivers can use it. They are invisible to older tele-visions.« That is especially interesting to movie lenders and television stations because they do not have to worry about compatibility. And even mobile radio and mobile phone manufacturers can join the trend towards 3-D with the MVC standard. In the meantime, there are even displays the size of a mobile phone that allow a good 3-D impression.

The experts from the HHI show how the MVC-Codec functions transmitting television via DVB-S2 satellite from September 10-14, 2010 at the IBC in Amsterdam.

High-Resolution Imagery from Two Data Streams

Side-by-side is not the only possibility when it comes to broadcasting and distributing 3D image streams. If there is no need to retain frame compatibility with existing MPEG-2 based broadcasting, there are a number of ways to transmit natural 3D images with no resolution degradation. One of these is the dual-stream approach (Fig. 5).

Fig.  Dual Stream Approach for Higher-Definition 3D Broadcasting
Diagram outlines dual stream broadcasting, now being considered for simultaneous transfer of multiple data streams. Korea is expected to begin 3D broadcasting in October 2010, packing MPEG-2 and H.264 data into a single channel on terrestrial waves (a). MVC and Sensio’s SENSIO Advanced also use dual streaming (b). The National Institute of Information and Communications Technology (NICT) is working on a concept called “depth broadcasting,” which will add depth information via the network to standard 2D broadcast data (c).

Compression

Compression/Decompression Technology Makes the Difference in Image Quality

That alone will not wholly resolve the compatibility issues between different 3D broadcasters and TVs, though. The problem is that there is a variety of implementation for the above-mentioned RealD and SENSIO 3D formats. Concretely, there are differences in image compression and decompression technology, and which (if any) error correction technologies are used. These differences manifest themselves as differences in image resolution and data processing speed in many cases. The details of the physical implementation will sway image fidelity and price.

Assuming that side-by-side is the easiest method to implement, then the horizontal image resolution after compression will degrade to half the source for both left and right images (Fig. 4). This compression is, in principle, non-recoverable, which means significant quality loss in unavoidable when the images are decompressed for viewing on the set. A number of proprietary specifications have emerged as engineers search for ways to minimize this image deterioration. A source at one broadcaster says “The difference in compression/decompression technology between the first 3D sets in about 2007, and the sets today, makes an enormous difference in image quality.”

Fig. Multiple Proprietary Specs for Side-by-Side Compression/Decompression
Differences in the compression/decompression technology used in side-by-side can result in significant differences in 3D image resolution, resistance of the transmission path to noise, data volume and interoperability.

3D Broadcasting Worldwide Technology

The broadcast signal input interface in television sets is actually settling on side-by-side technologyNote 1) (Fig. 2). Different manufacturers have adopted different approaches to displaying the 3D imagery, such as frame sequential (FS) or Xpol, but the input interface is fairly independent of the display technology. Panasonic and Sony say their 3D sets can handle 3D broadcasting and video distribution from BS11, Jupiter Telecommunications Co., Ltd. (J:COM) of Japan and SKY Perfect JSAT Holdings Inc. of Japan. BS11’s Endo adds “We are still verifying interoperability of sets from various manufacturers, but there aren’t any problems so far.”

Note 1) 3D TVs from Panasonic and Sony support side-by-side, High-Definition Multimedia Interface (HDMI) 1.4, and top-and-bottom, which inserts each images for left and right eye at the top and bottom of each frame.

Fig. 2 3D Imagery Display Method Independent of Broadcast/Transfer Data Format
Diagram shows content flow for display of 3D imagery on a 3D set. The multiplexing technology for the left and right images, broadcast encoding technology, and 3D image display technology are largely independent of each other.

†Frame sequential (FS) method: One method of displaying 3D imagery. The frame of the images for left and right eye are displayed alternately over time, synched to LCD shutter glasses for viewing.

†Xpol method: Another method of displaying 3D imagery. Polarizing film is affixed over the panel, and the polarization direction alternated for each horizontal row of pixels. The left and right images are displayed line-by-line.

Most 3D image broadcasting systems have adopted side-by-side because it ensures frame compatibility with existing broadcast technology (Fig. 3). In side-by-side, two images for left and right eye captured with the 3D camera are compressed into two frames, and broadcast as a single video frame. The television splits out the left and right images from the received frame, decompresses each to 2x and displays the result.

†Frame compatibility: A video frame using the new broadcasting method is still compatible with existing broadcast video frames, which means that the relay systems will not have to be changed when the broadcasting scheme is.

Broadcasting Technology: Interoperability or Resolution?
The side-by-side solution retains frame compatibility with existing 2D broadcasting, but horizontal resolution is roughly halved. MVC, on the other hand, offers high-resolution frames incompatible with existing schemes, making it impossible to use in general MPEG-2 based broadcasting.

Standards

Firing Up Competition for Industry Standard

Jun 1, 2010 00:05  by Tetsuo Nozawa

The three-dimensional (3D) imagery boom began back in about 2005, and is finally beginning to move into broadcasting. Moving pictures began in the 1890s, with moving pictures evolving from silent imagery to the “talkies,” from black-and-white to color, and recently to digital… the next step is full-scale 3D broadcasting and distribution services for 3D TVs. There are no standards yet, though, like an orchestra lacking a conductor. This article probes interoperability between competing broadcasting and distribution methods, and the future of standardization.

  • “It’s a whole new ball game this time, because 3D TVs are on the shelves, and the environment is ready for 3D broadcasting. Finally 3D broadcasting and 3D sets are both getting ready at the same time,” says Hiroshi Endo, Nippon BS Broadcasting Corp. (BS11) of Japan.
  • In December 2007, BS11 was the first broadcaster in the world to begin 3D broadcasting on an almost continuous basis. It stood alone for years, but the situation changed dramatically in 2010 as a host of broadcasters around the world began offering 3D broadcasting and distribution services using the same technology, and 3D-capable TVs became generally available from multiple manufacturers.
  • The 3D broadcasting method adopted by BS11 is called side-by-side broadcasting. It offers excellent compatibility with the Moving Picture Experts Group 2 (MPEG-2) high-efficiency coding scheme commonly used in broadcast data, which seems to be emerging as the de facto standard for 3D broadcasting. It is unclear whether or not it will be established as the standard, however, and it is entirely possible that side-by-side could end up as merely a transitional step.

Side-by-side: In the broadest sense, this applies to all transmission schemes sending the image streams for left and right eyes in parallel. 3D Video of the US began trial 3D broadcasting in Mexico in 1954, and today the general opinion in the industry is that side-by-side is not covered by a specific patent. In 1991, however, RealD, Inc. of the US claimed that it had acquired the basic patent for side-by-side. Concretely, two image streams compatible with existing broadcasting are compressed as left and right images positioned next to each other horizontally, transmitted, decompressed at the TV set, and displayed in a time-multiplexed manner. The image display is synched to the LCD shutter speed of the glasses worn by the viewer. The patent is US5193000. It expires in August 2011.

There are a number of issues involved with side-by-side, namely (1) existing side-by-side technology has limitations in terms of resolution (it cannot display full-high definition imagery) and 3D image fidelity, (2) there are a number of varieties of side-by-side, possibly making it impossible to guarantee interoperability between various broadcasts and sets, and (3) The International Telecommunication Union (ITU) and other standardization organizations are talking about standardizing H.264-based 3D broadcasting into addition to MPEG-2. In other words, 3D broadcasting standardization is only really starting now that a number of broadcasters and TV manufacturers are actually offering the commercial services (Fig. 1).

Fig. 1 Evolution Continues in 3D Broadcasting
Diagram shows future evolution in resolution and viewpoints for 3D broadcasting. Side-by-side and MPEG-2 are the most common technologies in use now, but H.264-based 3D broadcasting is likely to become more common in some satellite and networked services.

RealD Method Sweeping the Industry

  • It would be no exaggeration to say that the 3D broadcasting starting up around the world is all “private brand,” because the vast majority of it is using proprietary broadcasting methods. The 3D TV manufacturers have no obligation to support them all, and there are no guarantees that broadcast interoperability will be achieved. Worse, the various 3D broadcasters working on standardization are not pulling in the same direction: Most of them are primarily concerned about not falling behind in the surging “3D broadcasting” boom.
  • One 3D broadcasting/distribution technology has made great strides in the market in 2010, though: the RealD format for side-by-side, developed by RealD, Inc. of the US. Following the announcement by Sony Corp. of Japan in December 2009 that it had adopted the format, there was a rush of similar announcements at the 2010 International Consumer Electronics Show (CES) held in January 2010. Companies announcing adoption of the method include JVC Kenwood Holdings Inc. of Japan, Panasonic Corp. of Japan, Toshiba Corp. of Japan, Samsung Electronics, Co., Ltd. of Korea and DIRECTV, Inc. of the US.
  • RealD is famous for its 3D filming technology and viewing glasses, using polarized light, but it also holds a number of crucial patents in side-by-side transmission and LCD shutter glasses, for example. The flood of announcements at CES was driven by these resources. JVC Kenwood Holdings, for example, cited one of the key reasons for their selection of the RealD format as the fact that the firm already holds basic patents to side-by-side and 3D glasses.

Channel 4 3D Movie technology revealed

When Channel 4 demonstrates the wonders of 3D TV next week, the audience will need to wear coloured (anaglyph) glasses. No great surprise there, but I imagine most people will be expecting the traditional red-blue lenses. While familiar, the red-blue glasses can be quite uncomfortable to wear. The left, red lens is much darker than the right, and is used for depth cues rather than details. It give the 3D effect, but with a side-effect of making you feel uncomfortably like you are wearing an eye-patch.

A posh version of the Sainsbury 3D specsThankfully Channel 4 is using a more modern technology, though still anaglyph. It’s called ColorCode 3D, a patented version of anaglyph that uses amber and dark blue which allows a more balanced level of light through. It also makes colour range broader, for a more natural look. If you are in the UK you can pick up your glasses free from Sainsbury’s.

Presumably Channel 4 is working from original film in most of these cases, and will be encoding the video to match the ColorCode format. That means the footage exists in a format that could be encoded into any other format too. I’d love to see a parallel side-by-side version of the movies show up in iTunes.

RealD Launches First 3D Stereoscopic Converter ‘PODs’.

3D-PODs provide a plug-and-play solution for switching from CRT (cathode-ray tube) displays to other displays without software enhancements or plug-Ins:

  • LOS ANGELES — RealD Pro, the world’s most trusted 3D visualization source for industrial applications, has introduced the first 3D stereoscopic converter ‘PODs.’
  • The PODs present a simple conversion solution when upgrading to a new stereoscopic display monitor, such as a DLP[R] or XPOL HDTV.

Features:

  • The PODs automatically detect the output format from a connected display device and convert most stereo-enabled software applications from native stereoscopic output format to the required format for stereo viewing on the display monitor.
  • The RealD converter POD provides an immediate, affordable replacement option for CRT or LCD monitor users. When combined with DLP[R] TV kits available from RealD Pro, the user simply plugs the source data into the input port on the POD via an HDMI cable and the output HDMI cable into the 3D-ready HD TV.
  • The 3D converter PODs are designed specifically for research and development environments, where 3D visualization is heavily used and where departments or organizations are seeking alternatives to CRT display technology for stereoscopic applications. Industries include government and defense, entertainment, oil and gas, education, design and development, and medical.
  • The RealD 3D-PODs make this transition fast, easy, and inexpensive. The 3D-PODs also enable development teams to more easily present their work in front of customers or senior management, providing greater collaboration, improving productivity, reducing prototype expenses and accelerating time to market.

“RealD’s introduction of 3D-POD technology brings yet another tool to the industry, cost effectively facilitating 3D visualization,” said Michael Lewis, CEO of RealD. “As a leader in 3D visualization systems, RealD is committed to bringing new products to market that will enhance our customers’ abilities and services.”

Notes: The three PODs include dual input to checkerboard, side-by-side to horizontal interlace or checkerboard, and page-flip to checkerboard:

  • * Dual Input POD – a flexible dual stream video format conversion system that converts a dual stream of data into a checkerboard output for visualization in stereo or as simultaneous independent video streams using RealD’s new CrystalEyes 5 active eyewear. This POD also supports side-by-side conversion when using just a single input.
  • * Side-by-Side (SBS) 3D-POD – receives and transmits a single HDMI compatible audio / video signal. When the content is received in RealD SBS format, it is automatically converted into either checkerboard or horizontal interlace format, depending on the connected display device.
  • * Page Flip 3D-POD – converts a page-flip (frame sequential) stereo output to a checkerboard format for display on a DLP[R] TV. This POD is ideal for stereoscopic software applications used with CRTs.

Autostereoscopic 3D LCD


MASTERIMAGE 3D’s patented TN-LCD-based autostereoscopic technology allows for direct viewing of 3D content on flat screen displays (TFT-LCD, PDP, OLED) without the need for glasses.  Our ‘Cell Matrix Parallax’ display modules allow for the highest brightness and no crosstalk (ghosting).

  • Displays utilizing our ‘Cell Matrix Parallax’ technology can offer both portrait and landscape modes in 3D.  By utilizing TN-LCD technology, our displays can also switch between 2D and 3D modes.
  • Furthermore, MASTERIMAGE 3D has developed and patented a special manufacturing process that allows for precise alignment between our 3D module and the display.  Our equipment aligns each pixel of both panels with a maximum tolerance of 2 microns to ensure the highest manufacturing yield.

Features

  • High brightness level and wide viewing angle, delivering the sharpest and highest quality 3D images
  • Elimination of crosstalk (ghosting)
  • Switchable between 2D and 3D modes.  Reverse compatible with existing 2D content
  • Switchable between portrait and landscape modes in 3D, unique to ‘Cell Matrix Parallax’
  • Compatible with all existing flat display technologies
  • Cost effective – Manufacturing simplicity resulting in high yields

Technology

  • By modifying the cell structure of TN-LCDs to build the parallax barrier, we maintain cost effectiveness while greatly improving upon other parallax barrier-based technologies available in the marketplace.
  • Our technology uses a group of cells, by column unit, to form the parallax barrier instead of using conventional stripe type cells.
  • This methodology creates more gaps between cells, allowing for more brightness and no crosstalk.
  • This also allows for the ability to switch between portrait and landscape modes, as well as the ability to switch between 2D and 3D modes, all without compromising picture quality.

Posted by admin | 3D Tech | Monday 12 July 2010 00:31

Forum8, in cooperation with Subaru, displayed this driving simulator that used the company’s UC Win/Road Driving Simulator software. This was on display at the 3D & VR Expo in Tokyo, Japan: 

In addition to developing a variety of CAD, VR, simulation, and analysis software packages, Forum 8 also produces a series of drive simulators, made from the interior of authentic Hyundai vehicles.

In addition to this 3-monitor model, Forum 8 also produces a 3-monitor simulator mounted on a multi-axis motion platform, a single monitor simulator, and a compact demo simulator.

 

Forum 8 software UC-win/Road offers a wide variety of visualization options for civil engineering projects of all shapes and sizes.

UC-win/Road’s advanced traffic generation and analysis capabilities can be combined with its powerful road modeling features to create simulations for virtually any kind of project: roads and freeways, complex intersections and interchanges, on and off ramps, roundabouts – even railways and flight paths.

UC-win/Road also features 3D object animation and scripting capabilities, allowing the construction phases of a project to be visualized from start to finish.
