HDTV - High Definition Television
With the new technology spinning out of
factories everyday it is a wonder we can keep up with the new
terms and understand the information provided. When HDTV first
hit the market most people were wondering what it was and why
they may want to have it in their homes. It takes a little more
than the company providing the signal for HDTV.
HDTV is high definition television. This
means the signal you receive from DirecTV or Dish Network is
providing you with a digital transmission for your television to
decode. High definition television improves the quality of
signal you receive by the speed and resolution. The downside is
the television itself. If you have an older TV that does not
have a card to decode the HDTV signal you will not receive the
information in the quality those with a newer TV have.
Your television has to be set up to
receive the signal otherwise the programs that tout HDTV are not
providing you with that signal. Televisions like the plasma or
LCD screen are set up to receive these signals.
When you talk about HDTV in relation to
satellite television you should know a few things. DirecTV HDTV
is provided through the satellite dish to the receiver and
decoded along the coaxial cable to your television. Again in
order to receive the signal you do have to have the correct
television, but unlike cable, satellite TV is always a digital
signal. Even Dish Network HDTV has a digital signal to help you
receive HDTV.
The resolution of HDTV is normally 1280x720
pixels. When talking about pixels we mean the amount of tiny
pieces that create the whole picture. Think about photography
you see the photo as a whole picture, but it has pixels. If you
enlarge the picture you will see the pixels that actually makes
up the print. It is the same with high definition television.
The pixels are the picture the television is receiving from your
satellite service provider. All satellite receivers built in
the last ten years come with the HDTV built in. If you have a
receiver that is around 1990 chances are it does not have HDTV
capabilities if the receiver is still working.
When you upgrade you television you will
also want to upgrade your satellite equipment. The satellite
companies are improving technology just like the rest of the
world. Older versions of DirecTV don’t allow you to watch a
program while you are searching for something new to watch. Now
the new receivers are allowing you a picture in the corner while
you search for shows you might want to watch. The technology is
improving so you can record programs with a DVR and still watch
a program.
HDTV is just a small part of the technology
provided. As television watchers we all wan to have the
clearest picture that can be provided and why not? We spend
quite a lot of time in front of the television and the
technology is out there for us to use.
To view HDTV you need three things:
A source that provides a signal in HDTV.
A High Definition TV.
An Antenna to receive the signal.
