멀티화면 디스플레이를 위한 수평 샘플링 비율 변환방식에 있어서, 멀티화면 디스플레이를 위해 소정의 칼라서브 캐리어 주파수 비율로 디지탈 변환된 R-Y신호와 B-Y신호의 합성신호 혹은 휘도신호를 화면 분할 정보 신호의 상태에 따라 유한 임펄스 응답 필터링하여 상기 칼라서브 캐리어 주파수를 상기 화면 분할 정보신호의 상태에 따라 소정분주한 샘플링 주파수에 의거 샘플링하여 디지탈 신호처리 회로로 인가함을 특징으로 하는 방식.In the horizontal sampling rate conversion method for multi-screen display, a composite signal or luminance signal of the RY signal and BY signal digitally converted to a predetermined color subcarrier frequency ratio for the multi-screen display is defined according to the state of the screen split information signal. And impulse response filtering to apply the color subcarrier frequency to a digital signal processing circuit based on a sampling frequency divided by a predetermined frequency according to the state of the screen split information signal. 제1항에 있어서, 유한 임펄스 응답필털링 방식이 멀티화면 디스플레이를 위해 소정의 칼라서브 캐리어 주파수 비율로 디지탈 변환된 R-Y신호와 B-Y신호의 합성신호 혹은 휘도신호를 순차 지연시킴과 동시에 상기 화면 분할 정보신호의 상태에 따라 소정의 계수값과 각각 곱하여 각 승산결과를 가산함을 특징으로 하는 방식.The display apparatus of claim 1, wherein the finite impulse response filtering method sequentially delays a composite signal or a luminance signal of the RY signal and the BY signal, which are digitally converted at a predetermined color subcarrier frequency ratio, for the multi-screen display. And multiplying a predetermined coefficient value according to the state of the signal to add each multiplication result. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
