3D is an exciting new market for home theater. Some might play or magazines, 3D seems to be irrelevant. But made for sports, action movies in 3D, so much color difference between white and black. And the new 3D technology is superior to 3D was used in cinemas.
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 would start all movies in 3D computer animation. According to Dreamworks CEO Jeffrey Katzenberg, all major studios have 3D projects. It will be equipped more than 2500 theater screens with digital 3D technology by end 2009. All content for the home theater market. The big question:the will of the 3D market is fairly common for large networks, particularly the subset of the sport in a 3D program?
3D distribution
It is likely that satellite TV companies like DirecTV and Dish Network and distribution in 3-D version of HDTV programming. 3D films should use the same bandwidth as the other 120 fps (frames per second) high-definition movies. The spacecraft has enough bandwidth to support niche markets (cable companies are not), and now3D HDTV is a niche market.
"Satellite reduced lead not so much how many channels 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 satellite signal, an increase of 15% in 2002.
3D HDTV Home Theater Systems
With the refresh rate for 3D, and the need for synchronization LCD monitors are generally incompatible with 3D technologies.However, the prototype of Phillips on more than $ 20,000 has been shown, and this technology does not require glasses. The technology optically Phillips is very complicated. In contrast to electronics can be assumed that the price will fall.
Sold at the end of this year (2008), more than one million HD-Ready TVs DLP-3D, manufactured by Mitsubishi and Samsung, in which SU-art features and provides a signal of 60 Hz for each eye (equivalent to 120 Hz).These HDTV sets can display standard and are equipped with the 3D hardware is compatible. Some material for download, 3D and Blu-Ray 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) and 3D Field Sequential "or HQFS (High Quality Field Sequential. This technology uses electronic shutter glassesinstead of red-blue lenses we are used to at the movies. The effect is definitely superior. Our eyes see a slightly offset view of a scene. The two slightly different views are combined by the brain to result in our ability to see in 3D. Field Sequential 3D simulates this experience with shutter glasses. The shutter is not mechanical, but instead an LCD filter, that blocks vision when the opposite eye's view is shown.
A HDTV set with 120 Hz refresh rate is recommended for 3D viewing. The 3D system uses half of the total information for each eye. If you provide a television set with a total of 60 Hz refresh rate only 30 Hz for each eye, and the refresh rate would be visible (Flicker).
When designing a 3D system with 3D techniques, we have fully the choice between sending two signals bandwidth, twice the bandwidth of the signal, or by sending the signal, so that horizontal or vertical resolution halved, one half for eachEye. Doubling the bandwidth would be a problem, because the HDTV signal of bandwidth capacity is already at a premium. With 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, which is interesting because we worked so hard to increase our high-definition, we are not willing to compromise. The use of images of replacement for each eye, we see a high-definition signal without. flickers
Two sets of lenses, shutter speed wireless (with a control of the channel infrared (IR), the same technology as the TV remote control costs) is about $ 100.
"Hang-Ups" Brandishing DLP
Many consumers have a fascination with the idea that they hang their new big screen HDTV on the wall like a painting. Note that most LCD TVs and plasma larger never really mounted on the wall. This is a big challenge to get something at a weight of about 60-150 poundsthe wall, and once installed, is a constant challenge for the maintenance (eg, a 50-inch Pioneer PDP-5070HD weighs 128 pounds).
According to the NPD Group, only 13 percent of the current LCD TV owners and 25 percent of the owners of plasma TVs are all mounted on the wall.
DLP is very popular with those who want a better picture quality monitors at affordable prices. For the money, offers the highest quality DLP light size. An LCD of the same size and price is nothave the image quality of DLP. DLP is also available in larger sizes and a television with LCD screen.
However, it is a DLP rear projection TV a few inches thick, compared to an LCD or plasma. LCDs are typically 7-10 cm thick; September DLP are typically 12-17 cm thick. Why the fascination of their sentences mounted on the wall, this difference of a few centimeters, the deciding factor in purchasing decisions of many consumers.
Texas Instruments, which makes the DLPChip in a foundry in South Korea, sees the renewed potential of the technology that 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 had their specialties of LED lamp for a few years. The LED light engine will be replaced fairly often (unlike fluorescent lamps, cold cathode, will be replaced) every few years.
DLP HDTVLED engine are more efficient than the size of flat panel displays and the lack of a spinning wheel of color in the design means 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 an image without blurring of fast moving images like sports offer.
DLP HDTV equipment are a very wise choice for most people, but selective. Many games are not yet in stores HDTVhave an important technology, like LED backlighting.
The compatibility of the 3D-TV by the receipt on the back of the unit, called "3D-ready to be reviewed.
Home theater PC (HTPC)
An important trend in home theater is the integration of the personal computer (PC) with the home theater. Integration of a PC in your home entertainment center has many advantages, as well as enabling 3D video. Downloading movies is one of the advantages. TheHTPC need a video card with DVI (Digital Video Interface). Both XP and Vista support Microsoft products for home theater.
HDTV and 3D video is very computationally intensive, which means a high performance computer. For the 720p video, a heart twice a microprocessor is necessary to 1080p or 1080i video is a quad-core processor for smooth playback. Video files are very large (!), Disco the more the better.
DirectX 9 graphics driver (software)must be installed if not already there. To find the latest version, click on Start, then Run from the Windows desktop. Enter "dxdiag" box in "Run".
The software is used by various vendors, "Stereo" (version 1.3.4) from 3DTV.at disposal is available. Buy a stereo system is about $ 50 While you can also download 3DTV.AT GPL MPEG-1 / 2 decoder. Stereo alternatives include "Dynamic Digital Depth (ddd.com)," Stereoscopic Player "and "Tridef Visualizer.
Abstract
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 better with the 3D technology, where the plasma systems are available. DLP offers the best value for the big screen HDTV, and not only in the 3D high-definition.
