Claims (1)

영상신호의 수직방향 공간주파수의 고역성분이 저역성분에 비해 입력영상신호의 진폭에 무관계로 또는 입력영상신호의 진폭에 대응하여 상대적으로 레벨이 증강된 특성을 부여하는 수직방향 프리엠퍼시스회로를 적어도 통과한 영상신호를 기록매체에 기록하고, 상기 기록매체로 부터 재생된 신호를 상기 수직방향 프리엠퍼시스회로와 보완적 특성으로 선정된 수직방향 디엠퍼시스회로를 적어도 통과하여 본래의 파형으로 복원된 재생영상신호를 얻는 영상신호 기록 재생장치에 있어서, 상기 수직방향 프리엠퍼시스회로 및 상기 수직방향 디엠퍼시스회로에 대하여 입력영상신호의 수직귀선소거기간을 적어도 포함하는 일정기간은 그 동작을 실질적으로 휴지시켜 상기 입력영상 신호를 그래로 출력시키고, 상기 일정기간 이외의 기간만 그 출력신호를 취출하는 수단을 각각 설치한 것을 특징으로 하는 영상신호 기록재생장치.At least a vertical pre-emphasis circuit in which the high frequency component of the vertical spatial frequency of the video signal gives a relatively enhanced level to the amplitude of the input video signal regardless of the low frequency component or corresponding to the amplitude of the input video signal. The recorded video signal is recorded on a recording medium, and the signal reproduced from the recording medium is restored to its original waveform by at least passing through the vertical pre-emphasis circuit and the vertical de-emphasis circuit selected as complementary characteristics. A video signal recording and reproducing apparatus for obtaining a video signal, wherein the predetermined period including at least a vertical retrace period of an input video signal with respect to the vertical pre-emphasis circuit and the vertical de-emphasis circuit substantially stops the operation. The input image signal is output as it is, and only for a period other than the predetermined period, the output signal. And a means for extracting each of the video signal recording and reproducing apparatuses. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
