Description
Claims (4)
- 비디오신호와 OSD데이터간의 논리적 합성/변환하기 위한 시스템에 있어서,상기 비디오 신호를 수신하는 비디오수신부;커멘드필드와 파라메터필드로 이루어진 상기 OSD데이터를 수신하여 필드별로 구분하는 OSD수신부;상기 OSD수신부에서 구분한 필드 중 OSD데이터의 상기 커멘드필드를 디코딩하는 디코더부;상기 시스템의 전체 동작을 제어하며, 상기 디코더부에서 디코딩된 커멘드필드에 정의된 데이터처리방법에 따라 비디오신호와 OSD데이터를 가공하도록 지시하는 제어부;상기 제어부에 지시에 따라 비디오신호와 OSD데이터를 합성/변환하는 픽셀합성/변환부; 및상기 픽셀합성/변환부에 의해 합성/변환된 비디오신호를 출력하는 출력부를 포함하는 비디오신호와 OSD데이터의 합성/변환 시스템.
- 제 1항에 있어서, 상기 OSD데이터의 커멘드필드는 상기 OSD데이터의 픽셀단위로 부여되는 것을 특징으로 하는 비디오신호와 OSD데이터의 합성/변환 시스템.
- 제 1항에 있어서, 상기 제어부는 상기 OSD데이터가 파라메터로만 구성되어있는 경우, 기 저장해 놓은 적어도 하나의 OSD 커멘드에 따라 상기 비디오신호와 상기 파라메터를 합성/변환하는 것을 특징으로 하는 비디오신호와 OSD데이터의 합성/변환 시스템.
- 제 1항에 있어서, 상기 제어부는 상기 OSD데이터가 커멘드로만 구성되어 있는 경우, 상기 커멘드에 따라 상기 비디오신호만을 합성/변환하는 것을 특징으로 하는 비디오신호와 OSD데이터의 합성/변환 시스템.
