3d Movies – The Technology of 3D HDTV
Whats holding back 3D HDTV?
3D is a wonderful new feature for the home theater market. For some dramatic films or soap operas, 3D might seem out of whack. Except But for sports, action movies, etc.

black and white. And the new 3D technology is superior to the 3D system that has been employed in theaters. The commercial successes of fresh 3D films like “Beowulf”, “Meet the Robinsons”, and “Journey to the middle of the Earth”, is sparking interest with the movie studios to produce more 3D content material. Disney, Universal, Philips, Samsung, Sony, Thomson and IMAX are at present exploring the potential 3D HDTV market. According to Dreamworks Manager Jeffrey Katzenberg, all the major studios have 3D projects under way. There’ll be over 2,500 theatre screens supplied with the Digital 3D technology by the end of 2009. All of this content will be available to the home theater market.

3D films should take about the same bandwidth as other 120 fps [ frame per second ] high def movies.
The satellite corporations have enough broadcast bandwidth to support niche markets [ the cable companies do not ], and for now, 3D HDTV is a focused market.
“Satellite’s going to be constricted not so much by how many channels they can carry than by how many they can get,” recounted Bob Scherman, Satellite Business Stories . By 2010, it is projected that 60% of TV receivers in the United States will employ a satellite signal, up from 15% in 2002.

3D HDTV Home Theater Systems due to the high frame rate for 3D, and the requirement for synchronization, LCD screens are often incompatible with sophisticated 3D. However, prototypes by Phillips have been demonstrated at upwards of $20,000, and this technology does not require glasses. Unlike electronics, it will not be assumed that the price will come down. By the end of the current year [ 2008 ], more than 1,000,000 3D ready DLP HDTVs, manufactured by Mitsubishi and Samsung, will have been sold in the U.S.
The technology functions by supplying a sixty Hz signal to each eye [ equivalent to 120 Hz total ]. These sets can display standard HDTV, and are compatible with 3D material. “Hannah Montana and Miley Cyrus : Best of two Worlds Concert” was the first 3D Blu-ray Disc. The Glasses: Field Sequential 3D Special glasses are used with the DLP 3D system. This technology uses electronic shutter glasses instead of red-blue lenses we are used to at the films. The effect is certainly superior.
The 2 slightly different views are mixed by the brain to result in our capability 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 shutter is shown. A HDTV set with 120 Hz refresh rate is recommended for when The 3D system uses half the total information for each eye. If we use a TV with a total of sixty Hz refresh rate, it would supply only 30 total info for each eye, and that refresh rate would be obvious [ flicker ]. When conceptualizing a 3D system with prior 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 difficulty since the doubling the signal bandwidth capacity is already at a such that either Using the same bandwidth as non-3D material implies we are able to implement the technology with current HDMI or DVI interfaces.
