Abstract

본 발명은 브이씨알의 재생계에 관한 것으로, 특히 휘도신호와 색신호의 시간적 지연의 차이에 의해서 발생하는 화면상의 어긋남을 방지할 수 있는 브이씨알의 재생장치에 관한 것으로, 수평동기신호와 컬러 버스트의 위치를 검출한 다음 이 두 신호간의 차이에 의해 자연필터의 모드 저항값을 적절히 조정함으로써 그룹 지연의 차를 보상할 수 있어, 제품의 성능과 생산성의 향상을 기할 수 있도록 한 브이씨알의 재생장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a reproduction system of V-Cal, and more particularly, to an apparatus for reproducing V-Cal which can prevent screen deviation caused by a difference in time delay between a luminance signal and a color signal. By detecting the position and then adjusting the mode resistance value of the natural filter according to the difference between the two signals, the difference in the group delay can be compensated for, thereby improving the performance and productivity of the product. It is about.
