Abstract

본 발명은 시청자 선택형 자막방송의 팝은 스크롤방법에 관한 것으로서, 특히 수신되는 텔레비젼 신호의 비디오신호로부터 자막신호를 추출하는 단계; 추출된 자막신호로부터 디지탈 데이터를 복원시키는 단계; 복원된 데이터가 팝온모드인가를 체킹하는 단계; 팝온모드이면 제어코드중 수신저장 및 화면지움 명령을 삭제하는 단계; 문자코드에 대응하는 문자데이터를 한글 완성형코드에 의한 문자데이터가 저장된 폰트롬으로부터 리드하여 디스플레이 메모리에 저장하는 단계; 상기 디스플레이 메모리에 저장된 문자데이터를 비디오신호로 변환하여 스크린상에 디스플레이하는 단계; 줄바꿈 제어코드에 응답하여 화면상에 표시되는 팝온 문자를 스크롤시키는 단계를 구비한 것을 특징으로 한다.The present invention relates to a method of scrolling a pop of a viewer selectable type caption broadcasting, in particular, a method of extracting a caption signal from a video signal of a received television signal; Recovering digital data from the extracted caption signal; Checking whether the restored data is a pop-on mode; If the pop-on mode is selected, deleting the receipt storage and clear screen command in the control code; Reading the character data corresponding to the character code from the font ROM storing the character data by the Hangul complete code and storing the read data in the display memory; Converting the character data stored in the display memory into a video signal and displaying the converted video signal on a screen; And scrolling the pop-on characters displayed on the screen in response to the line feed control code.

따라서, 본 발명에서는 팝온 표시를 스크롤방식으로 할 수 있으므로 수신버퍼의 용량을 줄일 수 있어서 수신장치의 코스트를 다운시킬 수 있다.Therefore, in the present invention, since the pop-on display can be scrolled, the capacity of the reception buffer can be reduced and the cost of the reception device can be reduced.
