Many local TV stations are transmitting digital signals. However,
transmitting a digital signal does not mean transmitting an HDTV signal.
Some stations are using the new bandwidth to broadcast several
standard-definition channels. Most stations however, once they begin
broadcasting in digital, are offering HD content from their parent network (for
example, CBS, ABC, NBC, Fox, WB, UPN, PBS).

screen.

On standard HDTVs, the programming is displayed in letterbox format in
the middle of the screen. (There are bars surrounding the picture.)
