DTV Explained
In the beginning there was black & white (VHF ch. 2-13)
tv. In most areas there were only 2 or 3 tv stations. As
time went on stations started broadcasting in "Living
Color". At this point people with black and white tv sets
needed to upgrade to a color tv set. Soon after this all
new tv shows were in color.
The next progression in television was the
implementation of additional broadcast station. These
new stations used (UHF ch. 14-83). Not all tv's could
tune to these new station. This created the need for a set
top box that would tune in UHF channels 14 - 83. Now
days all tv's have both VHF and UHF tuners built into
them.
It's now time to go to the next level. There are more
broadcast channels available then ever before. Stations
are now digitally compressing (squeezing) 2 to 5
channels into 1 broadcast channel. While the stations
are still broadcasting using (VHF ch. 2-13) & (UHF ch.
14-83) the format is now digital. This can best be
compared to going from records to compact disks.
To tune into these digital channels you must have a
digital tuner. "Shop at FactoryOutletStore and enjoy Free

New tv sets will have a digital tuner built in. Older tv sets
have the old analog tuners in them and will not be able to
decrypt the digital signal. The way to work around this
problem is to use a set top box that can tune in to the
VHF/UHF station and decrypt the digital signal.
Once the set top box is hooked up to your antenna it
tunes in to a digital channel and it will then reformat it
from digital to analog and you will be able to view it on
your older tv set.
On June 12, 2009 the analog tv broadcast was
discontinued. Only the DTV format will be transmitted
from now on. You will need set top box or a tv with a
digital tuner in order to receive programs
Once you get your set top box hooked up you will have to
have it preform a scan for new channels. This is done
with the push of one button. Some boxes will preform this
function automatically when they are plugged in. After the
scan is completed your box is ready to use. You can
select your channels either with the channel up/down
arrows on your remote or you can direct tune using the
numbers on your remote.
If you use direct tune you will no longer enter you
channel numbers as single or double digits.
Example: To select channel 2 you will no longer enter 2
or 02.
What was channel 2 in the past with just one program on
it will now have anything from two to five programs on it
(each broadcaster will determine the amount of
programs). To select a program you must enter the
channel number plus the program number using a dot or
dash between the numbers.
Example A: To select channel 2 you would enter "2.1" or
"2-1". (some remotes use a dot others us a dash but the
function is the same)
Example B: To select channel 7 you would enter "7.3" or
"7-3". (some remotes use a dot others us a dash but the
function is the same)
In the example A: 2 is the channel number and 1 is the
program number. If you wanted program 4 you would
enter "2.4" or "2-4".
In the example B: 7 is the channel number and 3 is the
program number. If you wanted program 1 you would
enter "7.1" or "7-1".
Some set top boxes will have program guide listing. The
listing may look like example C.

Ch. 2.3 Weather
People who have cable or satellite should already have a
set top box in place to preform these processes. The
cable & satellite company's have done all the work for
you.
One last point of interest is that are a lot of company's
marketing DTV antenna's. If you already have a antenna
that you are have used to receive analog VHF/UHF tv
you can use the same antenna for DTV.
