3D is an interesting new market for home theater. For some drama or journals, 3D might seem irrelevant. But for sports, action movies, made in 3D, so much color difference between white and black. And the new 3D technology is superior to 3D was used in theaters.

The commercial successes of recent 3D films like "Beowulf" "Meet the Robinsons" and "Journey to the Center of the Earth, it is with interest that has attracted film studios to producehardware 3D content. Disney, Universal, Philips, Samsung, Sony, Thomson and IMAX are currently exploring the potential 3D HDTV market. Disney has said it wants to begin making all its movies in 3D computer animation. According to Dreamworks CEO Jeffrey Katzenberg, all major studios have 3D projects. There will be more than 2500 theater screens equipped with 3D digital technology by the end of 2009. All content is available for the home theater market.The big question: will the market for 3D is quite common for large networks, particularly the subset of the sports broadcast in 3D?

3D Distribution

It is likely that satellite television companies like DirecTV and Dish Network, and distribution of 3D version of HDTV programming before. 3D movies should take about the same bandwidth, like the other 120 fps (frames per second) high-definition movies. The satellite has enough bandwidth to support niche markets (cablecompanies do not), and for now, 3D HDTV is a niche market.

"Satellite will be constrained not so much how many channels can carry and how many can get," said Bob Scherman, Satellite Business News.

In 2010, it is expected that 60% of TV receivers in the United States the use of a satellite signal, an increase of 15% in 2002.

3D HDTV Home Theater Systems

Due to the refresh rate for 3D, and the need for synchronization,LCDs are generally incompatible with 3D technologies. However, the prototypes Phillips has been shown at more than $ 20,000, and this technology does not require glasses. The technology optically Phillips is very complicated. Unlike electronics, it can be assumed that the price will drop.

At the end of this year (2008), over one million HD Ready TVs DLP 3D, manufactured by Mitsubishi and Samsung, have been sold on functions in technologyproviding a signal of 60 Hz for each eye (equivalent to 120 Hz). These HDTV sets can display standard and are compatible with the 3D hardware. Some material is available for download, 3D and Blu-Ray are available. "Hannah Montana & Miley Cyrus: Best of Both Worlds Concert" was the first 3D Blu-ray Disc.

Glasses: Field Sequential 3D

Special glasses are used with the DLP 3D. The system is called Field Sequential 3D "or HQFS (HighQuality Field Sequential). This technology uses electronic shutter glasses instead of red-blue glasses that we have in the cinema. The effect is much greater. Our eyes see a vision of a little 'offset of a scene. Both views are slightly different from the brain to the combined result of our ability to see in 3D. Field Sequential 3D simulation experiment with shutter glasses. The shutter is not mechanical, but instead of a liquid crystal filter that blocks the display of sight when the eye is oppositeshown.

An HDTV and a refresh rate of 120 Hz is recommended for 3D visualization. The 3D system uses half of the total information for each eye. If using a TV with a total of 60 Hz refresh rate would provide only 30 Hz for each eye, and the refresh rate would be visible (Flicker).

When designing a 3D system with 3D techniques, we've a choice between sending two signals of equal bandwidth, full information, doubling the bandwidth of the signal, orsending the signal so that both the horizontal and vertical resolution is halved, one half for each eye. With the doubling of bandwidth would be a problem because the HDTV signal of bandwidth capacity is already at a premium. Using the same bandwidth as the non-3D hardware means that we can use current technology with HDMI or DVI.

The alternative to reduce the resolution is interesting, because we worked so hard to increase our high definition, therecompromise. Using images of replacement for each eye, we see a high definition signal without flicker.

Two sets of lenses, shutter wirelessly with a control of the transmitter (infrared (IR), the same technology that TV 's remote control) costs about $ 100.

"Hang-Ups" Brandishing DLP

Many consumers have a fascination with the idea of hanging up their new big screen HDTV on the wall like a painting. Note that most LCD televisions and plasma larger everactually get mounted on the wall. This is a major challenge to get something that weighs 60-150 pounds on the wall, and once installed, is an ongoing challenge for maintenance (for example, a 50-inch Pioneer PDP-5070HD weighs 128 pounds).

According to the NPD Group, only 13 percent of current LCD TV owners and 25 percent of the owners of plasma TVs are all mounted on the wall.

DLP is very popular among those who want the superior image quality of the displayaffordable. For the money, DLP provides easily the highest of quality-size. An LCD of the same size and price will not have the picture quality of a DLP. DLP is also available in larger sizes and TV with LCD screen.

However, a DLP rear projection TV is a few inches thick compared to a LCD or plasma. LCDs are typically 7-10 cm thick; September DLP are generally 12-17 cm thick. Why the fascination of their sets mounted on the wall, this differencefew centimeters becomes the determining factor in purchasing decisions of many consumers.

Texas Instruments, which makes the DLP chips in a foundry in South Korea, sees the renewed potential of technology, which uses tiny mirrors on a semiconductor. The new LED engine called "PhlatLight" (manufactured by Luminus) replaces the arc lamp and color wheel design of previous DLP HDTV. Samsung has had its own specialty LED lamp for a couple of years. The LED Light Engineto be replaced fairly often (unlike fluorescent lamps, cold cathode, which had to be replaced every few years).

DLP HDTV with an LED engine are more efficient than that of the size of flat screens, and the absence of a rotating wheel of color in the design means that place with less noise. The DLP chip is faster than any other HDTV technology, with the mirrors switching on and off over 15,000 times per second to provide an image without motion blur fastimages such as sports.

DLP HDTV sets are a very smart choice for most people, but selectively. Many games shops HDTV still missing important technologies, like LED backlighting.

The compatibility of the 3D TV to be verified by looking for input on the back of the unit, labeled "3D Ready".

Home Theater Personal Computer (HTPC)

An important trend in home theater is the integration of the personal computer (PC) withhome theater. Integrating a PC into your home entertainment center has many advantages, as well as enabling 3D video. Downloading movies is one of the benefits. The HTPC should have a graphics card with DVI (Digital Video Interface). Both XP and Vista support Microsoft products for home theater.

HDTV and 3D video is computationally intensive, which means a high-performance computer. For the 720p video, a heart double microprocessor is necessary, 1080i or 1080p videoneed a quad-core processor for smooth playback. Video files are very large (!), Disco more, the better.

DirectX 9 graphics drivers (software) must be installed if not already present. To find the current version, click on "Start" then "Run" from the Windows desktop. Type "dxdiag" in "Run" box.

The software is available from several different vendors, "StereoPlayer" (version 1.3.4) from 3DTV.at is available. StereoPlayer Buy is about $ 50. While you are 3DTV.AT also download the GPL MPEG-1 / 2 Decoder. Alternatives Stereoplayer include "Dynamic Digital Depth (ddd.com)," Stereoscopic Player "and" Tridef Visualizer.

Summary

3D technology has become a major force in Hollywood. It is likely that this trend will be repeated in the home theater. CRT and DLP work better with the 3D technology, where systems of plasma are also available. DLP offers the best value for the big screen HDTV, and not only in 3D> HDTV.
