Abstract
본 발명의 목적은 하이밴드 모드를 선택하여 고화질의 영상을 기록/재생할 수 있도록 한 브이씨알(VCR)의 고화질 전용회로에 관한 것으로 이와같은 본 발명은 안테나로 수신된 복합영상신호의 레벨을 조정하는 자동이득 제어수단과, 상기 자동이득 제어수단으로 부터 출력된 복합영상신호를 저역 필터링하여 휘도신호를 출력하는 저역필터 수단과, 상기 저역필터 수단으로 출력된 휘도신호를 클램핑하는 클램프 회로와, 선택된 모드에 따라 상기 클램프 회로에서 클램핑된 휘도신호의 주파수를 조정하여 해상도를 제어하는 해상도 제어수단을 구성함으로써 달성되어지는 것이다.An object of the present invention is to provide a high-definition dedicated circuit of VCR capable of recording / reproducing high-definition video by selecting a high-band mode. The present invention adjusts the level of a composite video signal received by an antenna. Automatic gain control means, low-pass filter means for low-pass filtering the composite video signal output from the automatic gain control means, and outputting a luminance signal, a clamp circuit for clamping the luminance signal output to the low-pass filter means, and a selected mode By adjusting the frequency of the clamped luminance signal in the clamp circuit according to the configuration to achieve the resolution control means for controlling the resolution.
