Abstract

The present invention relates to a recording device of a VCR, and more particularly, to a recording device and a method of a VCR to change the recording mode more conveniently.

Such a recording device of the VCR of the present invention is a Tu / IF unit of the VCR for outputting an IF signal by tuning an intermediate frequency high-frequency signal input and processing an intermediate frequency, and the composite image signal output from the Tu / IF unit of the VCR. A video detector which detects only a video signal, an audio detector that detects only an audio signal from a composite video signal output from the Tu / IF unit of the VCR, and a composite video high-frequency signal on a TV set, and intermediate frequency processing the video signal. And an image detection unit of the TV for processing and outputting the audio signal, and a synchronization signal detection unit for detecting and outputting a synchronization signal from the video signal output from the image detection unit of the TV. A first switching unit for inputting a signal output from the video detector and a video signal output from the image detector of the TV through a cable and selecting and outputting one through a cable; and a signal and cable output from the audio detector A second switching unit which selects and outputs one of the audio signals output from the image detector of the input TV, a video signal processing unit which processes the video signal output by the first switching unit, and an output by the second switching unit An audio signal processing unit for processing an audio signal, and recording the signals output from the video signal processing unit and the audio signal processing unit on a video tape, respectively; A second recording system, a synchronous signal detector for detecting and outputting a synchronous signal from the video signal processor, a remote controller receiver for receiving a user's control signal, and a synchronous signal detector and a synchronous signal detector of a TV It is provided with a microcomputer to control the recording / playback function of the VCR by receiving the synchronization signal of the video signal and controlling the first, second switching unit and the first, second recorder, etc. by the control signal received from the remote control receiver. In the recording method of the VCR of the present invention, when the recording mode selection signal is input again (REC) of the recording mode (REC), the first step of checking the presence or absence of the synchronization signal of the video signal input from the outside, and the synchronization signal in the first step If not, the current recording mode is maintained, and a second step of selecting and recording a video signal input from the outside is performed.
