3D is an exciting new market for home theater. Could be dramatic for some movies or soap operas, 3D seems out of place. But for sports, action movies, etc. 3D is much difference between color vs. black and white. And consider the new 3D technology is the 3D system, which is used in cinemas.
The commercial successes of recent 3D films like "Beowulf," "Meet the Robinsons" and "Journey To The Center Of The Earth", arousing the interest is with the studios for the production ofother material contained 3D. Disney, Universal, Philips, Samsung, Sony, Thomson and IMAX are currently exploring the potential 3D HDTV market. Disney said it would start all computer animated films in 3D. According to Dreamworks CEO Jeffrey Katzenberg, all major studios have run a 3-D projects. There are more than 2,500 theater screens equipped with digital 3D technology by the end of 2009. All content will be available for the home theater market. The big question:the 3D market quite common for large networks, particularly the sports section, in 3D program?
3D distribution
It is likely that companies like DirecTV and Dish Network satellite TV, the first 3D version of HDTV programming distributed. 3D movies should have the same bandwidth as the others take 120 fps (frames per second) high-definition movies. The satellite companies have sufficient bandwidth to support niche markets (the cable companies do not), and now,3D HDTV is a niche market.
"Satellite is not limited in how many channels are those that, like many can get," said Bob Scherman, Satellite Business News carried.
By 2010 it is expected that 60% of TV receivers in the United States, a satellite signal will be used by 15% in 2002.
3D HDTV Home Theater Systems
Because of the high frame rate for 3D, and the need for synchronization LCD screens are generally incompatible with advanced 3D.However, Phillips is in pre-production of $ 20,000 is presented, and this technology does not require glasses. Phillips-optic technology is very complicated. In contrast to the electronics can not be assumed that the price will drop.
Manufactured by the end of this year (2008), more than one million 3D-ready DLP HDTV, Mitsubishi and Samsung have sold up the technology works by applying a signal of 60 Hz for each eye (equivalent to 120 Hz in total).These HDTV sets can display standard and are compatible with the 3D material. Part of the source material is available for download from the 3D and Blu-Ray are always available. "Hannah Montana and 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 system. The system is) as "Field Sequential 3D" or HQFS (High Quality Field Sequential. This technology uses electronic glasses shutterInstead of red and blue lenses, which we used in the film. The effect is greater in every case. Our eyes see a vision of a little 'offset of a scene. The two slightly different views are combined by the brain to the result of our ability to see in 3D. Field Sequential 3D simulates the experience with the shutter glasses. The shutter is not mechanical, but a liquid crystal filter, this vision, if the other eye is shown having the blocks.
An HDTV with 120 Hz refresh rate is set for 3D-TV is recommended. The3D system uses half of the total information for each eye. If we have a TV function, with a total of 60 Hz refresh rate, it would be only 30 Hz for each eye problems, and the frame rate will be visible) (Flicker.
In developing a 3D system with earlier 3D technologies, we have a choice between two of the bandwidth of the transmitted signals with all the information, the effective bandwidth of the signal or the signal is doubled, so that either half horizontal or vertical resolution, halffor each eye. The doubling of bandwidth would be a problem, since the HDTV signal of bandwidth capacity is already at a premium. With the same range as non-3D material means that we can use the technology with the latest HDMI or DVI.
Cut The alternative to dissolution is not interesting, because we worked very hard to improve our high-definition, we are not willing to compromise. Through the use of an alternative framework for each eye, we see a high definition signal without. Flickers
Two sets of wireless shutter glasses, with a transmitter control (Infrared (IR), the same technology as the TV remote control) costs about $ 100.
"Hang-Ups" Holding up DLP
Many consumers have a fascination with the idea of hanging up their new big screen HDTV on the wall like a painting. It is worth noting that it is never more LCD and plasma screens really great on the wall. It 'a great challenge, something to weigh 60-150 pounds for the mountainthe wall, and once installed, is a constant 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 have their device mounted on the wall.
DLP is very popular among those who want larger displays high quality images at affordable prices. For the money, DLP offers simply the highest quality value dimensions. A non-LCD of the same size and pricehave the image quality of DLP. DLP is also available in larger LCD TVs, then.
However, it is a DLP rear projection TV a few inches thick compared to an LCD or plasma. LCD screens are typically 7-10 cm thick, set of DLP are typically 12-17 cm thick. Wegen der Faszination für die Montage-Sets an der Wand, so wird diese Differenz von ein paar Zentimeter entscheidende Faktor für den Kauf der viele Entscheidungen des Verbrauchers.
Texas Instruments, DLP manufacturersChip in a foundry in South Korea, sees the potential for a new technology that uses tiny mirrors on a semiconductor. The new LED light 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 few years ago. The LED light engine rarely needs be replaced (unlike the cold cathode fluorescent lamps, which had to be replaced every couple) of years.
DLP HDTVwith an LED engine are more energy efficient with relatively large flat screens, and the lack of a moving color wheel in the development, they play with less noise. The DLP chip is faster than any other HDTV technology, with the mirrors switching on and off moving more than 15,000 times per second the image without blurring of fast images like sports delivered.
DLP HDTV sets are a very wise choice for most people, but selective. Many of the high-definition televisions in stores have not yetimportant technologies like LED backlighting.
Reconciliation will be considered for 3D-TV is seeking input on the back of the unit, "3D Ready".
Home Theater PC (HTPC)
An important trend in home theater is the integration of the personal computer (PC) with the home theater. The integration of a PC in your home entertainment center has many advantages, as well as enabling 3D video. Downloading movies is one of the benefits. TheHTPC should be) a video card with DVI (Digital Video Interface. Both XP and Vista supports Microsoft products for home theater.
HDTV and 3D video is computationally intensive, which means a high-performance computer. For 720p video is a dual-core microprocessor is required, 1080p or 1080i video need a quad-core processor for smooth playback. Video files are very large (!), So that the larger the unit, the better.
Graphics card DirectX 9 software (driver)must be installed if not already exist. For the current version, click on "Start" and then click Run from the Windows desktop. Enter "dxdiag" in "Run" box.
The software is available from several manufacturers, "Stereo" (version 1.3.4) is available from 3DTV.at. The purchase of the stereo is about $ 50. While you're at 3DTV.AT Download GPL MPEG-1 / 2 decoder. Alternatives to a stereo system includes Dynamic Digital Depth (ddd.com), "Stereoscopic Player" and"Tridef Visualizer.
Abstract
3D technology has become a major force in Hollywood. It is likely that the repetition of this trend in home theater. CRT and DLP work best with 3D technology, but also those of plasma are available. DLP offers a better relationship with big-screen HDTV, not only 3D-HDTV.
