Abstract

본 발명에 의한 CIF 영상신호 디스플레이 장치 및 방법은 수신된 CIF 영상신호를 디스플레이함에 있어서 CIF영상 신호를 직접 디스플레이 가능한 CIF 복합 영상신호로 변환시켜 디스플레이 하는 장치 및 방법에 관한것으로, Y·Cb·Cr형태의 CIF 영상신호를 출력하는 소스디코더와, D/A변환부와, Y·Cr·Cb형태 영상신호를 복합영상신호로 변환하여 디스플레이부로 공급하는 칼라스페이스변환부를 구비하여, CIF 영상신호를 다른 형식의 영상신호로 변환시키지 않고 직접 디스플레이하므로써 디스플레이 장치 및 방법을 간소화 시킬수 있다.CIF image signal display apparatus and method according to the present invention relates to an apparatus and method for converting a CIF image signal into a CIF composite image signal that can be directly displayed in the display of the received CIF image signal, Y · C b · C a CIF image including a source decoder for outputting an r- type CIF video signal, a D / A converter, and a color space converter for converting a Y / C r · C b- type video signal to a composite video signal and supplying it to a display unit The display apparatus and method can be simplified by directly displaying a signal without converting it into a video signal of another format.
