Abstract
본 발명은 VCR의 하이 파이 오디오 오검출 방지장치 및 방법에 관한 것이다.The present invention relates to an apparatus and a method for preventing hi-fi audio erroneous detection of a VCR.
본 발명은 종래 하이 파이 트랙에는 기록이 되지 않는 3배속 모드의 테이프 재생지 노이즈를 RF로 인식함으로써 노이즈를 하이 파이 오디오 신호로 출력하게 되는 문제점이 있었던 점을 감안하여 재생신호로부터 하이 파이 오디오 신호 성분을 검출하는 제1검출부와, 상기 오디오 재생 신호의 하이 파이 오디오 신호를 제거한 신호를 검출하는 제2검출부와, 상기 제1검출부와 제2검출부에서 출력되는 신호를 비교하는 비교부와, 상기 비교부의 비교결과에 따라 하이 파이 오디오 출력을 제어하는 제어부를 구비하여 비상적인 RF와 정상적인 RF의 주파수 차이에 따라 비정상적인 RF시는 출력되지 않도록 함으로서 비정상적인 RF에 의한 하이 파이 오동작을 방지할 수 있도록 한 것이다.In view of the fact that the tape playback paper noise in the triple speed mode which is not recorded in the conventional hi-fi track is RF, the noise is outputted as a hi-fi audio signal. A second detector for detecting a signal from which the hi-fi audio signal of the audio reproduction signal is removed; a comparator for comparing the signal output from the first detector with the signal output from the second detector; And a control unit for controlling the output of the hi-fi audio according to the result, so that the hi-fi operation due to the abnormal RF can be prevented by preventing the abnormal RF from being outputted due to the difference between the emergency RF and the normal RF.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.
제3a도, 제3b도는 정상적인 오디오 RF와 비정상적인 오디오 RF의 스펙드럼도.Figures 3a and 3b also show the specifications of normal audio RF and unusual audio RF.
