An RF Modulator is
an electronic device for converting audio/video signals into RF
(radio frequency) signal. RF modulators are used to connect DVD
players, video game systems, camcorders and other video components
to TV sets without Audio/Video inputs. The connection is made from
the DVD (or other component) a/v outputs to the RF Modulator and
from the RF Modulator to the TV's antenna input jack.

line-level signals into an RF output signal. (necessary for
televisions with only a 75-ohm RF coaxial input)
