3D is a new interesting feature for the home theater market. For some drama or soap opera, 3D might seem out of place. But for sports, action movies, etc. vs. 3D is very different in black and white. And the 3-D technology is higher than the new 3D system that was used in theaters.
The commercial successes of recent 3D films like "Beowulf" "Meet the Robinsons" and "Journey to the Center of the Earth," iswith the studios for the production of 3D content material sparks interest. Disney, Universal, Philips, Samsung, Sony, Thomson and IMAX are currently examining the potential 3D HDTV market. Disney said it would start all their computer-film 'in 3D animation. According to Dreamworks CEO Jeffrey Katzenberg, all major studios have 3D projects. It will be more than 2,500 screens equipped with digital 3D theater technologyEnd of 2009. All this content will be available for the home theater market. The big question: will the pervasive enough market for 3D large networks, especially the part of sports broadcasting in 3D?
3D distribution
It 's probably the first satellite-television companies like DirecTV and Dish Network programming, distribute versions of 3D HDTV. 3D films are all about to take the same bandwidth as the other 120 fps (framessecond) high def movies. The satellite companies have enough broadcast bandwidth to support niche markets (the cable companies do not), and for now, 3D HDTV is a niche market.
"Satellite's going to be constrained not so much by how many channels they can carry than by how many they can get," said Bob Scherman, Satellite Business News.
By 2010, it is projected that 60% of TV receivers in the United States will use a satellite signal, up from 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, prototypes by Phillips have been demonstrated at upwards of $20,000, and this technology does not require glasses. The Phillips technology is optically very complicated. Unlike electronics, it cannot be assumed that the price will come down.
By the end of this year (2008), more than one million 3D ready DLP HDTVs, manufactured by Mitsubishi and Samsung, will have been sold in the U.S. The technology functions by supplying a 60 Hz signal to each eye (equivalent to 120 Hz total). These sets can display standard HDTV, and are compatible with 3D material. Some source material is available for download, and Blu-Ray 3D discs are becoming available. "Hannah Montana and Miley Cyrus: Best of Both Worlds Concert" was the first 3D Blu-ray Disc.
The Glasses: Field Sequential 3D
Special glasses are used with the DLP 3D system. The system is called "Field Sequential 3D" or HQFS (High Quality Field Sequential). This technology uses electronic shutter glasses instead 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 we use a TV with a total of 60 Hz refresh rate, it would supply only 30 Hz to each eye, and that refresh rate would be visible (flicker).
When designing a 3D system with previous 3D techniques, we have the choice of either sending two equal bandwidth signals with full information, effectively doubling the signal bandwidth, or sending the signal such that either the horizontal or vertical resolution is halved, one half for each eye. Doubling the bandwidth would be a problem since the HDTV signal bandwidth capacity is already at a premium. Using the same bandwidth as non-3D material means that we can use the latest technology with HDMI or DVI interfaces.
The alternative for the resolution is to cut off-putting, because we worked so hard to improve our high-definition, we do not want to jeopardize. The use of alternative frames for each eye, we see a high definition signal without flicker.
Two sets of wireless glasses, with a transmitter (infrared (IR), the same technology as the TV remote control) costs about $ 100.
"Hang-upHolding on DLP
Many consumers have a fascination with the idea of hanging their new big screen HDTV on the wall like a painting. It is worth noting that most LCD and plasma TV has never really great mounted on the wall to get there. It 's a great challenge, something that weighs 60-150 pounds on the wall, and once installed, is a constant challenge for the maintenance (for example, a 50-inch Pioneer PDP-5070HD weighs 128 pounds).
According to the NPD Group, only13 percent of current LCD TV owners and 25 percent of plasma TV owners have installed their unit on the wall.
DLP is popular among those who want to monitor more high image quality at affordable prices. For the money, the DLP light provides the highest value for size. An LCD of the same size and price is not the picture quality of DLP. DLP is also available in screen sizes larger LCD then.
However, a DLP rear projection television a few inches thick compared to a LCDor plasma. LCDs are generally 7-10 cm thick, pre-set DLP are usually 12-17 cm thick. Because of the appeal of their sentences on the wall mounting, this difference of a few centimeters of the deciding factor for many consumers purchasing decisions.
Texas Instruments DLP chip that produces in a foundry in South Korea sees the potential for renewed technology that uses tiny mirrors on a semiconductor. The new engine called PhlatLight LED "(produced byLuminus replaced), the arc lamp and the front wheel of the DLP HDTV color design. Samsung had its owner LED lamp for a few years. The LED engine should be replaced often (in contrast to the cold cathode fluorescent lamps, which had to be replaced every few years).
DLP HDTV with an LED engine are more energy efficient similar-sized flat panel displays and the lack of a color wheel in motion design, leading to less noise. DLPChip is faster than any other HDTV technology, with the mirrors switching on and off over 15,000 times per second to provide a sporty image without blurring for fast moving images like.
DLP HDTVs are a very good choice for most people, but selective. Many of the HDTVs in the stores do not have major technologies, like LED backlighting.
The compatibility of the TV and 3D can be re-checked with the search for an item onUnits, with "3D Ready".
Home Theater Personal Computer (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 the home entertainment center has many advantages as well as enabling 3D video. Downloading movies is one of the benefits. The HTPC should be a graphics card with DVI (Digital Video Interface). Both XP and Vista, the Microsoft productfor home theater.
3D and HDTV video is computationally intensive, so a high-performance computers. For the 720p, is a dual-core microprocessor needed, 1080p or 1080i video requires a quad-core chip for video playback smooth. Video files are very large (!), So the bigger the hard drive, the better.
DirectX 9 graphics driver (software) must be installed if not already exist. In order to upgrade to "Start" and then "Run" from theWindows desktop. Type "dxdiag" in the "Run".
Software from multiple vendors, "stereo" (version 1.3.4) is available from 3DTV.at. Acquisition of stereo is about $ 50. While you're there 3DTV.AT also download the MPEG-1 / 2 decoder GPL. The alternatives to a stereo system are "Dynamic Digital Depth (ddd.com)," Stereoscopic Player "and" TriDef Visualizer. "
Summary
3D technology has become a driving force in Hollywood. E 'likelyThis trend is repeated in the home theater. CRT and DLP-work best with the 3D technology, even though the plasma systems are also available. DLP offers better value with large HDTV screens, not just 3D HDTV.
