DTV
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

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.
Example C:
Ch. 2.1 News
Ch. 2.2 Sports
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.
