KR970050714A - VCR recording device during CD / CDG playback of VCR and CD / CDG composite systems - Google Patents

Abstract

The present invention relates to a VCR and a CD / CDG composite system including a VCR and a CD / CDG, wherein the VCR is a recording device during CD / CDG playback, which enables the VCR to perform recording during CD / CDG playback.

To this end, the present invention selects one of a CD audio signal (CDA), an external audio signal (LINA) input from an external line, and a TV audio signal (TVA) input through a TV so that the audio recorder of the VCR can be recorded. An audio input selector 17 to output, an external video signal LINV input from an external line, a TV video signal TVV input through a TV, and a CD video signal CDV are selected to select a video of the VCR. The video input selector 18 outputs for recording on a recorder, the CD audio signal CDA, the external audio signal LINA input from an external line, the TV audio signal TVA input via a TV, and the VCR. An audio output selector 6 which selects one of the reproduced audio signals VCRA input from the audio reproducing system and outputs it as an audio signal, inputs from the CD reproducing system 20 of the CD video signal CDV and VCR A video output selector 13 for selecting one of the outputted playback video signals VCRV and outputting it as a video signal, an audio output selector 6, a video output selector 13, and an audio input according to a user's function selection By controlling the selector 17 and the video input selector 18, the CDG servo system is operated, and the audio and video output selector 6, 13 selects CD video (CDV) and CD audio (CDA) And a microcomputer 11 for allowing the audio input selector 17 and the video input selector 18 to select input audio and video to perform a recording function while outputting as video.
