3 Dimensional High Definition Technology For Television
Three dimensional film technology was first pioneered in the 1970s. It is also known as 3D IMAX technology and goes towards making movie viewing an unforgettable experience in theaters. The screen is as big as the normal theater screen and several speakers produce a multi-channel stereo effect. The speakers are placed around the theater and also behind the screen so as to create effect of real world sound from various sources.
How is it produced?
3D photos and movies are produced with the help of two cameras and an image is stored for each eye. Two projectors are directed towards the screen. Since there is a unique image for each eye, depth or a three -dimensional effect is produced. What actually happens is that the viewer watches two images at a given point of time, which are kept apart with the help of special polarized glasses.
3D technology in Television for home viewing
It has been proved that people love to watch 3D movies though it costs more because the technology now is quite different from that used in normal television. Another drawback is that viewer has to watch the television through polarized glasses.
Two types of glasses are currently available -circular polarized and active LCD shutter so that each eye sees a different image to give the 3D effect. In shutter glasses the lens gets blacked out very quickly to suit the display on a High definition TV. The TV is connected to an IR emitter which conveys signal to the glasses.
Shutter glasses are best suited for home viewing as the TV can be viewed from any angle. The colors are also more precise and the contrast between left and right eye is more. Hence this proves to be the most reliable and accurate 3D technology suited for home viewing.
3D technology for homes is still in its early stages. Lot of companies are trying to make the technology more user friendly and cost effective. The cost of the glasses is, however, exorbitant. Additionally it is seen that there is lot of flickering and the image also is a bit dimmed. The latest HDTVs do claim that these are no longer real issues. Sony is one of the consumer electronics companies which are working hard to make this technology successful so that it can be widely used. How much would it be accepted by an average consumer still remains to be seen.
Big HDTV like 50 inch plasma TV holds out the promise of the first 3D displays. They will work just like other HDTV but can additionally be viewed in 3D form. To top it all, these new 3D HDTVs will be available at a cost similar to a normal HDTV.

Lost: The Complete Third Season [Blu-ray] $24.73 When it aired in 2006-07, Lost’s third season was split into two, with a hefty break in between. This did nothing to help the already weirdly disparate direction the show was taking (Kate and Sawyer in zoo cages! Locke eating goop in a mud hut!), but when it finally righted its course halfway through–in particular that whopper of a finale–the drama series had left its irked fan base thrilled onc… |
