TV technology of the future, there is an even more advanced type of technology on the horizon that could eclipse it! This technology is 3D HDTV.



an HDTV set, but it's also capable of producing images that appear in three dimensions. In fact, these devices can give viewers the impression of being surrounded by images. One review of a prototype of this technology reported a very realistic effect of butterflies and flower petals that seemed fly directly out of the screen toward the viewer.

3D technology isn't new. Back in the 1960s, 3D movies were popular, but they required wearing 3D glasses with polarized lenses which caused the eyes to see a picture with depth, often giving their wearers intense headaches. The technology that 3D HDTV is based on is different. A 3D HDTV screen really shows various images at various angels. images will enter each of the viewer's eyes and provide the illusion of depth.

The more different angles of an image that the TV displays, the more realistic the three dimensional effect.

Not without its problems is naturally 3D HDTV technology. several different angles of the same image at once- while projecting them in different directions- is quite a feat. One thing that adds to the complexity of this problem is the fact that the more distinct angles of the image that the TV can display, the more realistic the effect is. when people are moving in front of the screen.

the image is to appear choppy to someone passing in front of the TV screen.

the viewer is less likely to catch them while moving and looking at the screen.

Fortunately the latest models of these sets are able to display their images in enough angles to provide a pretty realistic effect under a variety of conditions. The use of 3D HDTV's as a means of attracting consumers' attentions in public makes this particularly valuable.

While there are functioning prototypes of 3D HDTV displays, they're extremely expensive at a cost of over twenty thousand dollars to produce! price down rapidly to the point where they could be widely available- and mostly affordable- within a few years.

But then, the large hindrance will be trying to fill the sets with content. What might be quite amazing, is that the progress has already began in the situation. Steve Spielberg is working on a movie in 3D, as is James Cameron,for example. There is also software being developed that has the promise of converting two dimensional HDTV programming into three dimensions.

This fascinating technology could make HDTV obsolete just as it seems to be getting off the ground.
