DTV is short for Digital Television;
it can also be called ATV, which is Advanced T.V. The first broadcast
date for DTV was in July of 1996. DTV is only available in a 16*9
ratio. This ratio is what is used for movies that are shot for the
big screen. Standard TV is at a 4 by 3 ratio. That is 4 units wide
by 3 units tall. DTV has three types of scanning to produce a picture
the first is 480p system which is better than standard TV. 720p
which is much better than standard TV and 480p but requires more
bandwidth. Last is 1080i that has the ultimate picture and sound
experience. Most DTV contains 1125 lines of resolution. |
DTV is going to be the standard for all television
by the year 2006 or at least the FCC hopes. There have been several
extensions for this conversion already. However DTV is going to
be the next standard for the whole world not just the U.S.

| The Future of DTV is a
good one. With the FCC pushing full throttle, it is sure to succeed
for a little while. DTV allows better than movie theater picture
quality and CD sound quality for a better all around TV experience.
A new technology called HDTV is helping to develop this digital
new world. HDTV has the best picture quality the world has ever
seen and DVD quality audio. The benefits of DTV are faster reception,
more information faster because of larger bandwidth, better picture
quality, and more channels. |
