Here are answers
to some of the questions we're frequently asked.
Q: I've heard about
Digital Television and High Definition Television.
What's the difference?
A. You have found the
key question. They are not the same.
Digital television
(DTV) simply means the signal is transmitted
as a bunch of ones and zeros. Right now, direct
home satellite systems use a digital system to send
signals to your home (where most likely, you convert
them back to analog TV to play on your TV set).
Some cable services do the same thing.
At this point, all
commercial television stations in our area are operating
a digital service on a separate channel from where
you now watch them. NBC 23 has its digital service
(KVEO-DT) on channel 24.
You cannot see digital
TV on a regular (or analog) television. You will
need a new, special digital TV set or set-top-box
to see the new digital TV channels.
Digital television
has some big advantages. The picture you get is
exactly what the station sends out. There
is no "snow" or "ghosts" on digital TV. You either
get the picture or you don't. The audio is also
much clearer with the same range you expect from
CD's.
High Definition
Television (HDTV) is a special wide screen,
super sharp, version of digital TV. HDTV is transmitted
with about five times the amount of picture information
and up to six channels of digital audio. It will
provide the viewer with a clarity and picture quality
you need to see to believe. It also appears on a
wider-screen (much more like a movie screen).
There isn't enough
"room" (bandwidth) on the current TV channels to
send HDTV and continue to provide you with today's
television.
NBC 23 has begun HDTV service. But as this new medium
starts, not all of KVEO's television shows are produced
in HDTV.
We are carrying in
HDTV all NBC shows that are produced in that format
(and that's much of NBC's primetime schedule). All
the rest of our schedule is being "converted" to
a picture that looks a lot like HDTV and plays on
your HDTV but isn't true HDTV. [Click here

As time passes and more and
more people have HDTV, more and more shows will
be produced in this new format.
Q. Is HDTV expensive?
A. Prices have come down a lot. But
top of the line, large screen, plasma HDTV's could
cost you $4,000 or more. Other HDTV TV sets are
selling in the range of $1,500 and up. Projection
HDTV's range from about $1,200 to $5,000.
But just like color, most people believe
those prices will come down as more and more people
want HDTV and competition gets stronger. Already,
in the last few years, we've seen prices come down
about a thousand dollars a TV.
And the set manufacturers point out
that the early color TV's, relative to the black
and white TV of the 50's, were actually more expensive.
Q. I hear that my old TV will become
obsolete soon. That doesn't sound fair.
A. When the Government developed the
plan for the transition from today's (analog) TV
to digital Television, back in the 90's, they guessed
it would be complete this year. They predicted most
all TV's in your home would be the new digital ones.
However, because that hasn't happened, the deadline
has now been extended to February 17, 2009. On that
date, unless the government delays it again,your
non-digital TV's will no longer pick-up any over-the-air
signals.
The Government has plans for many
of the old, analog TV channels NBC 23 and other
local TV stations now use. The expansion of cell
phones and other wireless devices makes these frequencies
very valuable. Today's TV channels are being sold
to other industries.
