Definition: RF out

(Radio Frequency out) Refers to coaxial sockets on the back of set-top boxes, VCRs and DVDs that output analog video signals for older TVs that do not have composite video or component video inputs. Since the video source controls the channels or source material, the "RF out" signals are modulated onto a channel 3 or 4 carrier, and the TV is set to that channel. Contrast with RF in. See F connector and RF.
