Abstract

본 발명은 디스플레이 할 문자의 칼라를 지정하거나 배경 칼라를 지정할때 칼라 문자가 쓰여진 위치에 칼라 변경없이 노멀 문자를 디스플레이하기에 적당하도록 한 문자다중 방송을 이용한 온 스크린 디스플레이 장치에 관한것으로 문자 데이타의 종류를 검출하여 데이타의 종류에 따라 스위칭시키는 제어 문자 검출수단, 문자를 저장하고 저장된 데이타를 동시에 읽어내는 버피 제어 및 메모리 제어 수단, 데이타의 종류를 해독하여 제어 문자여부에 따라 문자제어를 변경하거나 유지시키는 제어 문자 출력 수단을 구비하여 이루어진다.The present invention relates to an on-screen display device using character multicasting, which is suitable for displaying normal characters without changing colors when a color character is designated or a background color when displaying a color. Control character detection means for detecting and switching according to the type of data, buffy control and memory control means for storing the character and reading the stored data simultaneously, and changing or maintaining the character control according to the control character by decoding the type of data. Control character output means.
