Abstract
본 발명은 고화질 TV의 2배속 신호에 요구되는 라인 보간신호 발생장치 및 방법에 관한 것으로써 수입 의존도가 높아 가격상승의 원인이 되었던 원칩(one-chip) IC로 된 보간신호 발생기를 저렴하고 구하기 쉬운 TTL과 메모리를 이용하여 구성하고 원신호와 보간신호를 리드 인에이블 신호에 의해 출력 하였으며 특히 보간신호를 발생하는데 단지 2개의 가산기와 메모리로 된 지연기를 이용하였다.The present invention relates to an apparatus and method for generating line interpolation signals required for double speed signals of high definition TVs. It consists of TTL and memory, and outputs original signal and interpolation signal by read enable signal. Especially, only two adders and memory delayers are used to generate interpolation signal.
이와같은 발명으로 고가의 라인 보간신호 발생기의 수입에서 탈피하여 경제성을 기할 수 있고, 2배속 신호의 선명한 TV영상을 재현할 수 있다.This invention can be economical by avoiding the import of expensive line interpolation signal generator, it is possible to reproduce a clear TV image of the double speed signal.
