Abstract

본 발명은 무방송신호시 OSD문자표시 제어회로에 관한 것으로, 방송신호의 재생처리에 대해 설정되는 메뉴 방식에 관한 OSD문자표시를 행하는 컬러텔레비전에서 방송신호에 포함된 수직/수평동기신호에 기초하여 OSD 문자를 생성하는 제어부(30)와, 상기 반송신호에 포함된 수직/수평동기신호를 검출하여 상기 제어부(30)에 수직/수평동기신호와 동기검출신호를 출력함과 더불어 무반송신호시기준동기신호를 생성하여 OSD문자표시의 위치설정을 위한 기준신호로서 상기 제어부(30)에 출력하는 신호처리부(40), 이 신호처리부(40)에 접속되어 복합영상 신호를 얻는 신호트랩부(80), 이 신호트랩부(80)에 의해 얻어진 복합영상신호를 휘도/색신호분리하여 상기 신호처리부(40)에 인가하는 신호분리부(90), 무방송신호시 상기 신호처리부(40)에 의해 내부동기신호가 얻어지도록 노이즈성분을 바이패싱하는 신호제어부(100)를 포함하여 구성되어, 메뉴방식의 기능제어를 행하는 컬러텔레비전에서 무방송신호시 신호처리부에서 자체적으로 생성되는 동기신호를 이용하여 OSD문자의 위치설정이 가능하도록 하여 무방송신호에도 기능제어메뉴의 표시를 위한 OSD문자가 안정적으로 표시될 수 있도록 한 것이다.The present invention relates to an OSD character display control circuit for a non-broadcast signal, the OSD being based on a vertical / horizontal synchronization signal included in a broadcast signal in a color television for displaying OSD characters for a menu method set for reproduction processing of a broadcast signal. The controller 30 generates a character, and detects the vertical / horizontal synchronization signal included in the carrier signal, outputs a vertical / horizontal synchronization signal and a synchronous detection signal to the controller 30, and the reference synchronization signal at the time of no transport signal. A signal processor 40 which generates a signal and outputs it to the controller 30 as a reference signal for positioning the OSD text display; a signal trap unit 80 connected to the signal processor 40 to obtain a composite video signal; The signal separation unit 90 is configured to separate the luminance / color signal obtained by the signal trap unit 80 into the signal processing unit 40 and to apply the signal to the signal processing unit 40. The signal control unit 100 bypasses the noise component so that the position of the OSD characters can be set by using a synchronization signal generated by the signal processing unit in the case of a non-broadcast signal in color television that performs menu-based function control. In this way, the OSD characters for displaying the function control menu can be stably displayed even in a broadcast-free signal.
