Abstract

본 발명은 텔레텍스트모드에서 OSD문자 위치제어장치에 관한 것으로, 방송국에서 전송되는 영상신호화 음성신호 및 그 영상신호에 포함되어 전송되는 텔레텍스트신호의 재생처리기능을 구비한 텔레비전에 있어서, 페이지 단위로 선택되어 재생되는 상기 텔레텍스트신호의 재생모드를 선택하기 위한 키입력수단과, 상기 텔레텍스트신호의 자막데이터를 검출하기 위한 텍스트신호추출수단, 상기 텔레텍스트신호의 선택을 위한 페이지 리스트 바를 화면표시하기 위한 제어와 상기 텍스트신호추출수단에 의해 텔레텍스트신호의 자막이 검출되면 상기 페이지 리스트 바의 화면표시 위치를 제어하기 위한 마이콤, 상기 마이콤의 제어하에 위치변경된 페이지 리스트 바의 OSD신호를 발생하여 CRT장치상에 표시되도록 하는 OSD발생수단을 구비하여 구성되고, 상기 마이콤은 상기 자막검출수단에 의해 검출된 상기 페이지 리스트 바의 표시위치에서 텔레텍스트신호의 자막이 위치하는 경우 상기 페이지 리스트 바의 OSD신호가 중첩되지 않도록 위치변경되게 제어하는 것이다.The present invention relates to an OSD character position control apparatus in a teletext mode, comprising: a unit of a page in a television having a reproduction processing function of a video signalized audio signal transmitted from a broadcasting station and a teletext signal included in the video signal and transmitted. A key input means for selecting a reproduction mode of the teletext signal selected and reproduced, a text signal extraction means for detecting subtitle data of the teletext signal, and a page list bar for selecting the teletext signal; To control the screen display position of the page list bar when the caption of the teletext signal is detected by the text signal extracting means and to generate the OSD signal of the page list bar which is repositioned under the control of the micom. An OSD generating means for displaying on the apparatus, Microprocessor-based control is to be changed so as not to overlap the OSD signal of the page list bar position if the subtitles in the teletext signal on the display position of the location of the page list bar detected by the caption detection unit.
