ABSTRACT:
In a video recording/reproducing apparatus, an automatic power-saving circuit determines the existence of an input video signal and controls recording/reproducing functions accordingly, whereby recording/reproducing functions continue if an input video signal is present, and, if no video signal exists and no function key is input for a predetermined period of time, the recording/reproducing actions are halted and power is automatically cut-off.
