Description

PAL 칼라 영상신호 기록 재생방식 및 그 기록매체PAL color video signal recording and reproducing method and recording medium thereof

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 의한 PAL 칼라 영상신호 기록 재생방식의 기록시스템의 한 실시예를 도시한 계통도.1 is a schematic diagram showing an embodiment of a recording system of a PAL color video signal recording and reproducing method according to the present invention.

제2도는 그 재생시스템의 한 실시예를 도시한 계통도.2 is a schematic diagram illustrating one embodiment of the playback system.

제3도는 본 발명 방식의 PAL 칼라 영상신호의 대역분할의 한 예를 도시한 도면.3 is a diagram showing an example of band division of a PAL color video signal according to the present invention.

제4도는 기록된 신호의 주파수 스펙트럼의 한 예를 도시한 도면.4 shows an example of the frequency spectrum of the recorded signal.

제5도는 동일 주파수대역에 주파수 변환 중첩된 주파수 변환신호의 스펙트럼도.5 is a spectrum diagram of a frequency converted signal in which frequency conversion is superimposed on the same frequency band.

Claims (2)

PAL 칼라 연상신호를 저역, 중역 및 고역의 3개의 주파수 대역신호로 분할하여, 저역신호에서 반송파를 변조하여 주파수 변조신호를 만들고, 중역신호 및 고역신호는 동일주파수 대역에 각각의 신호성분이 서로 인터리브하도록 주파수 변환시켜 주파수 변환신호를 만들어, 이들 주파수 변환신호 및 주파수 변환신호를 혼합하여 기록재생하는 것을 특징으로 하는 PAL 칼라 영상신호 기록 재생방식.The PAL color associative signal is divided into three frequency band signals of low, mid and high frequencies, and the carrier is modulated from the low frequency signal to generate a frequency modulated signal. The mid and high frequency signals are interleaved with each other in the same frequency band. A PAL color video signal recording and reproducing method, characterized by generating a frequency conversion signal by frequency conversion so as to mix and reproduce the frequency conversion signal and the frequency conversion signal. 지역, 중역 및 고역의 3개의 주파수 대역신호로 분활된 PAL 칼라 영상신호의 저역신호에서 반송파를 변조하여 얻은 주파수 변조신호와 저역, 중역 및 고역의 3개의 주파수 대역신호로 분할된 PAL 칼라영상신호의 중역신호 및 고역신호를 각각의 신호성분이 서로 인터리브하도록 동일주파수대역에 주파수 변환시켜 얻은 주파수 변환신호를 혼합하여 기록되어 있는 기록매체.A frequency modulated signal obtained by modulating a carrier wave in a low frequency signal divided into three frequency band signals of a region, a mid range, and a high frequency, and a PAL color image signal divided into three frequency band signals of a low, a mid range, and a high range. A recording medium in which a mid-range signal and a high-frequency signal are mixed and recorded by mixing a frequency converted signal obtained by frequency converting each signal component in the same frequency band so as to interleave each other. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
