Digital Television
FAQs
What
is DTV? |
DTV is short for a digital television
signal that's transmitted by encoding images as zeroes
and ones. (Calculators, computers, compact discs and the
Internet are examples of digital technology.)
DTV has a distinct advantage over today's analog signal.
It can compress images, enabling a station to broadcast
four, five or more channels on the same bandwidth required
for our current standard television signal. |
Why do we have
to convert to DTV? |
Analog broadcasting is a messy, inefficient use of
a limited broadcast spectrum. Like the dial on your car
radio, it can only accommodate a certain number of stations/signals,
so space on the spectrum is prime real estate.
Digital technology condenses broadcast signals to make
room on the spectrum for cellular phones, paging, and
other systems. By auctioning that space, the government
hopes to add billions to the U.S. Treasury and reduce
the national debt. |
How
will we pay for DTV? |
Commercial broadcasters are looking
to advertisers to pay the freight.
NHPTV estimates that it will cost approximately $10 million
to convert its studio broadcast equipment and its five
transmitters from analog to digital technology.
Like our sister stations in the PBS community, we know
that raising funds at this level within the community
is an insurmountable challenge, and so we're looking to
both federal and state governments for help.
WENH-DT 57 in Deerfield, NH, began digital transmission
in September 2000. WLED-DT 48 in Littleton, NH, began
transmission in April 2002. WEKW-DT 49 in Keene, NH began transmission in June 2003.
The FCC has not given channel assignments to the two remaining
translators in Pittsburgh and Hanover, so their sign-on
dates are yet to be determined. |
How much will
digital sets cost? |
Prices for digital TV sets start at $1,500; most cost
much more. But television is the nation's largest mass-market
product--more homes have TV sets than telephones--so prices
are expected to drop rapidly. |
Must
I buy a new TV set? |
Not for a long time. You can purchase
a converter box for about $400. They resemble boxes provided
by cable companies, and they'll "translate"
the digital signal so you can view it on your analog set.
Reception will be better than what you presently receive,
but not as crisp as you'd get with a digital unit.
The FCC has set February 9, 2009 as the date when traditional
analog television broadcasts will end. At that time you will
need to replace your TV set, get converter boxes, or continue
watching the signal through your cable company who will probably
convert it to a format that you can still watch on your analog
television. |
Will I still
be able to get cable service? |
Yes, without any noticeable difference. |
Will
I still be able to watch my favorite old programs? |
Yes, networks will be reformatting
programs in their current library to meet the digital
standard. Some programs, like movies and filmed dramas
shot in high-quality film, already work digitally. |
I have a huge
video collection. Will I still be able to watch these
videos? |
Yes, if you maintain your current equipment. It's
like having 45-rpm records or 8-track recordings. At some
point you may want to convert your videos to digital recordings.
In a few years, that equipment will be available to consumers. |
