Title: 다중 오에스디(osd)에서의 하이라이트 처리 방법
Filed: 1998-04-23
Abstract: 본 발명은 디지탈 티브이(DTV), 디지탈 브이씨알(DVCR) 등의 디지탈 영상표시기기에 있어서, 한 화면상에 여러개의 OSD(On Screen Display)가 표시되는 다중 OSD 상태에서 특별히 원하는 부분의 색을 변경시켜 그 부분을 하이라이트(High light) 시킬수 있도록 하는 다중 오에스디(OSD)에서의 하이라이트 처리 방법에 관한 것이다. 
     종래 OSD 하이라이트 처리 방법에 있어, 윈도우 기반 하이라이트 처리 방법은 계속적인 윈도우 포인트를 저장하고 있어야만 하기 때문에, 다중 OSD에 있어, 복수개의 OSD 하이라이트 처리가 요구되어질 경우에 있어, 하드웨어의 부담이 증가하는 문제점이 있다. 
     본 발명에서는 OSD 영역(Region)을 정의하는 메모리 헤더정보에 하이라이트를 결정하는 플레그(flag)를 설정하고, 플레그의 셋팅에 따라서, 각 OSD 영역별로 하이라이트 처리를 실행하도록 하므로써, 다중 OSD의 하이라이트를 구현함에 있어, 하드웨어의 부담없이 다수개의 OSD에 대한 하이라이트를 처리할 수 있도록 한 것이며, 또한 OSD 영역내의 부분적인 하이라이트 처리 및 OSD 영역간의 하이라이트 처리는 윈도우 기반 하이라이트 처리 방법을 이용하여 이루어질 수 있도록 하므로써, 다중 0SD에서의 다양한 OSD 하이라이트 처리가 가능하도록 하는 것이다.
