lies beyond the year 2000?
Back when TVs were first released, they were in black & white and this was normal. No one thought twice about them being in black & white. These days, if we all had to go back to watching black and white televisions, we may have a problem with it. Recently, Digital High Definition Television has been released. This delivers an extremely better quality picture, than normal TVs that we have available these days. Also, Digital Video Discs (DVDs and Digital Versatile Disc when dealing with computer DVDs) have been becoming more and more popular. These contain extremely high quality full length video in it. They can contain up to around 17Gb of video or data.
In the future we are going to see many more fantastic devices like these, however much better. We can expect to see highly advanced TVs that may even be a 3D glass cube that displays the image in all directions.
Infect, a physicist named Parviz Soltan is actually working on a 3D TV. He has already built a 1 metre high glass cylinder that recreates a 3D picture inside it. You can view it from all angles, you can look down at it from the top and the sides and you see the image. It uses red, green and blue lasers to create the picture, which are linked to computers which tell the lasers what to do. Places like airports can use this in air traffic control towers so they can see the planes in 3D. Unlike radar screens where the image of several planes can be on top of one another and working out the altitude can be difficult, they can tell with this new system instantly by looking at it, and if several planes are overlapping on it, it means they have already crashed. In the future, we could be watching TV on one of these.
