Abstract
본 발명은 비디오 카세트 레코더(VCR)의 오디오 및 비디오 라인 잭 자동 절환방법에 관한 것으로, 이를 위해 상기 입력 및 출력라인 잭을 통하여 입력 또는 출력되는 신호를 분석하는 단계와; 상기 단계에서 라인 모드와, 이이(electrical to eleclrical; EE) 모드중에서, 레코딩 모드인 경우에만 상기 오디오 및 비디오 둘다를 입력단으로 설정하고, 그외 다른 모든 경우에는 오디오 및 비디오 둘다를 출력단으로 설정하는 단계로 이루어짐으로써, 사용하기가 보다 용이하고, 인쇄 회로 기판의 면적을 감소시킬 수가 있다.The present invention relates to a method for automatically switching audio and video line jacks of a video cassette recorder (VCR), comprising: analyzing a signal input or output through the input and output line jacks; In this step, among the line mode and the electrical to eleclrical (EE) mode, both audio and video are set as inputs only in the recording mode, and in all other cases, both audio and video are set as outputs. By doing so, it is easier to use and the area of the printed circuit board can be reduced.
