3-D DLP HDTV

3D is an exciting new feature for the home theater market. For some drama or soap opera, 3D might seem out of place fails. But black sports, action movies, 3D, etc. makes much difference and color vs. black. And is larger than the new 3D technology, the 3D system 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 sparks interest with movie studios for the production ofmore 3D material. Disney, Universal, Philips, Samsung, Sony, Thomson and IMAX are exploiting the market potential 3D HDTV. Disney said it would launch all its computer-animated films in 3D. According to Dreamworks CEO Jeffrey Katzenberg, all major studios have run through 3-D projects. There will be more than 2,500 theater screens with digital 3D technology by the end of 2009 equipped All these contents are available for home theater market. The big question:3D is the market quite common for large networks, particularly for the sports, the transmission in 3D?

3D distribution

And 'likely that satellite television companies like DirecTV and Dish Network, the 3D versions of HDTV to be distributed before. 3D movies should take about the bandwidth of the other 120 fps (frames per second) high-definition movies. The company satellite transmission of sufficient bandwidth for niche markets (cable companies are not), and now support3D HDTV is a niche market.

"Satellite is not limited, as to those channels which have from what they wear," said Bob Scherman, Satellite Business News.

By 2010, provides that 60% of TV receivers in the U.S. is to use a satellite signal, compared to 15% in 2002.

3D HDTV Home Theater Systems

Due to the 3D high frame rate and the need for synchronization, LCD screens tend to be incompatible with the advanced 3D.However, prototypes Phillips has been demonstrated by $ 20,000, and this technology does not need glasses. Technology Phillips is visually very complex. In contrast to electronics, can not be assumed that the price will fall.

By the end of this year (2008), has produced over one million 3D-ready DLP HDTV Samsung and Mitsubishi, in the U.S. The characteristics of the technology have gone through the delivery of a signal of 60 Hz for each eye (equivalent to 120 total Hz sold).These sets can display HDTV standard and are compatible with a 3D material. Part of the original material is available for download, and Blu-Ray 3D are available. "Hannah Montana and Miley Cyrus: Best of Both Worlds Concert" was the first 3D Blu-ray Disc

Lenses: Field Sequential 3D

special glasses are used with the system 3D DLP. The system is called "Field Sequential 3D" or HQFS (High Quality Field Sequential). This technology uses electronic shutter glassesinstead of the red-blue lenses that we used in the film. The effect is clearly superior. Our eyes see something offset view of a scene. The two slightly different views will be combined by the brain, resulting in our ability to see in 3D. Field Sequential 3D simulates the experience of shooting glasses. The shutter is not mechanical, but a filter to block the LCD display when the other eye is displayed.

An HDTV sets with 120 Hz refresh rate is recommended for 3D visualization. The3D system uses half of the total information for each eye. If you use a TV with a total of 60 Hz refresh rate, it would only lead to 30 Hz for each eye, and refresh rate that would be visible (flicker).

When designing a 3D system with earlier 3D technologies, you can choose between two signals of bandwidth with all the information, have in fact a doubling of the bandwidth of the signal, or sending the signal, so that half Resolution horizontal or vertical, and one half for eachEye. Doubling the bandwidth would be a problem because the HDTV signal of bandwidth capacity is already an award. With the same bandwidth as non-3D-material resources that we use the latest technology with HDMI or DVI.

The alternative to cut the resolution is not interesting because we worked hard to improve our high-definition, we make no compromises. The use of alternative framework for each eye, you see a high definition signal without flicker.

Two setswireless shutter glasses with a transmitter control (Infrared (IR), the same technology as TV remote control) costs about $ 100.

"Hang-Ups" Holding 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 big wall mounted to obtain. It 'a great challenge, something that weighs 60-150 pounds on the wall, and once Mountinstalled, 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 current LCD TV owners and 25 percent of owners of plasma TVs have their device mounted on the wall.

DLP is very popular among those who want to monitor a large high quality at affordable prices. For the money, lightweight DLP offers the highest quality value-size. An LCD the same size and price is not the pictureQuality of a DLP. DLP is also available in larger screen sizes, LCD televisions then.

However, a DLP rear projection TV a few inches thicker than an LCD or plasma screen. LCDs are usually 70-10 cm thick; September DLP are typically 12-17 cm thick. Because of the fascination is his attachment to the wall, this difference is a few inches of a deciding factor for many consumers' purchasing decisions.

Texas Instruments DLP chip that produces a foundrySouth Korea sees potential for the renewal of a technology that uses tiny mirrors on a semiconductor. The new LED Engine Call "Phlatlight" (manufactured by Luminus) replaces the arc lamp and color wheel design of previous DLP HDTV. Samsung had their property LED lamp for a few years. The LED light engine must be replaced often (as opposed to cold cathode fluorescent lamps, which had to be replaced every few years).

LED DLP HDTV with an engineenergy efficiency compared to the same size flat panel displays and the lack of a moving color wheel design means that race with less noise. The DLP chip is faster than any other HDTV technology, with mirror and off over 15,000 times per second, an image without blurring for fast moving images like sports provide.

DLP HDTV sets are a very good choice for most people, but be selective. Many of the HDTVs in the stores are still importantTechnology as LED backlighting.

The compatibility of 3D television can be verified by looking for input on the back, with "3D Ready.

Home Theater Personal Computer (HTPC)

An important trend in home theater is the integration of personal computers (PCs) with the home 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 shoulda graphics card with a DVI (Digital Video Interface). Both XP and Vista will support Microsoft products for home theater.

HDTV and 3D video is computationally intensive, so a high-performance computer. For 720p video, is a dual-core microprocessor needed; 1080p or 1080i video requires a quad-core microprocessor for ultra-smooth playback. Video files are very large (!), So that the larger the hard drive, the better.

DirectX 9 graphics driver (software) must be installed whendo not already exist. For your version, click on "START" and then "Run" from the Windows desktop. Type "dxdiag" in the "Run.

The software is available from several manufacturers, "stereo" (version 1.3.4) is available from 3DTV.at. Acquisition of stereo is about $ 50. While you're 3DTV.AT also download the GPL MPEG-1 / 2 decoder. Alternatives to TV include "Dynamic Digital Depth (ddd.com)," Stereoscopic Player "and" TridefVisualizer.

Summary

3D technology has become a major force in Hollywood. It is likely that this trend will be repeated in home theater systems. CRT and DLP-work best with 3D technology, though plasma systems are also available. DLP offers better value with large HDTV screens, not just 3D HDTV.
