Abstract

본 발명은 시스템의 작동을 제어하는 데이터가 입력되는 명령 입력부에 캡션/부가정보 모드에 해당된 데이터가 입력되면 이에 따라 제1,2표시구동부와 주변 장치의 작동을 전반적으로 제어하여 상기 제1,2표시 구동부에서 출력되는 신호를 좌우 화면에 디스플레이하는 시스템 제어부와, 상기 시스템 제어부에서 출력되는 제어 데이터에 의해 안테나에 수신되는 고주파신호중에서 선택된 채널의 텔레비전신호를 복조한 후 비디오 신호를 출력하여 비디오 신호 처리부에 공급하는 튜너부의 출력단에 접속되어 송출된 자막 신호를 디지탈 신호로 변환하여 출력하는 아날로그/디지탈 변환부와, 상기 아날로그/디지탈 변환부에서 디코딩된 데이터를 어드레스로하여 폰트롬에 저장된 데이터를 독출하여 자막 신호로 처리함과 동시에 디코딩된 데이터를 판별하여 캡션이면 문자 신호를 제1출력포트를 통해 비디오 처리부에서 출력되느 비디오 신호가 공급되는 믹서기에 공급하고, 부가정보이면 제2출력포트를 상기 부가 정보에 해당된 신호를 출력하여 제2표시구동부에 공급하는 자막처리부등으로 구성되어, 시청자의 희망에 따라 일기예보나 긴급뉴스등과 같은 부가 정보와 캡션을 한 화면에 동시에 디스플레이 하므로 시청자가 화면의 대사 자막을 보면서 일기예보나 긴급 뉴스 등을 한 화면으로 볼 수 있는 시청자 선택형 한 화면 캡션/부가 정보 디스플레이 회로에 관한 것이다.According to the present invention, when data corresponding to the caption / additional information mode is input to the command input unit to which data for controlling the operation of the system is inputted, the operation of the first and second display drivers and the peripheral devices is controlled, A demodulator for demodulating a television signal of a selected channel among the high frequency signals received by the antenna according to the control data output from the system controller and outputting a video signal, An analog / digital conversion unit connected to an output terminal of the tuner unit connected to the processing unit, for converting the transmitted caption signal into a digital signal, and outputting the digital signal; and a controller for reading out data stored in the font ROM using the data decoded by the analog / And the decoded data is discriminated If the caption is caption, the character signal is supplied to the mixer to which the video signal outputted from the video processing unit is supplied through the first output port. If the caption is the additional information, the second output port outputs the signal corresponding to the additional information to the second display driver And a subtitle processing unit for supplying the subtitle information and the subtitle information to the viewer, and displays supplementary information such as a weather forecast or emergency news on a screen on the screen at the same time as the viewer wishes. And a screen caption / additional information display circuit which is selectable by the viewer.

Claims

When the data corresponding to the caption / additional information mode is input to the command input unit to which the data for controlling the operation of the system is inputted, the operation of the first and second display drivers and the peripheral devices is controlled overall, A demodulator for demodulating the television signal of the selected channel among the high frequency signals received by the antenna according to the control data output from the system controller and outputting the video signal to the video signal processor An analog / digital conversion unit connected to an output terminal of the tuner unit and converting the subtitle signal transmitted from the tuner unit into a digital signal and outputting the digital signal; and a controller for reading data stored in the font ROM using the data decoded by the analog / And at the same time, decodes the decoded data, And supplies the surface character signal to the mixer to which the video signal outputted from the video processing unit is supplied through the first output port and outputs the signal corresponding to the additional information to the second display driver And a first and a second display RAM for supplying the caption data output from the caption processing unit to the caption processing unit for converting the caption data corresponding to one page different from the caption data to the caption processing unit for alternately converting the caption data into a video signal, A display caption / additional low-level display circuit which is selected by the viewer.
