ABSTRACT:
An apparatus and a method for recording/playing back a broadcasting signal wherein the broadcasting signal is separated into a video signal and an audio signal and then written into video and audio signal memories. The video and audio signals are read from the video and audio signal memories if a HISTORY mode key is ON. The operation is ended if a REVIEW key is OFF under the condition that the HISTORY mode key is off. If the REVIEW key is ON the write operation of the video signal into the video signal memory is stopped and it is discriminated whether a JOG key is ON or OFF. A video signalportion of a predetermined previous interval is read from the video signal memory if it is discriminated that the JOG key is OFF. If the JOG key is ON, a read timing signal is generated to read the video signal from the video signal memory according to an operation of the JOG key. The video signal is read from the video signal memory with an address being incremented, if it is discriminated that the JOG key is operated clockwise. If it is discriminated that the JOG key is operated counter-clockwise, the video signal is read from the video signal memory with the address being decremented.
