Abstract

적어도 하나 이상의 튜너를 가지고 수신되는 방송 프로그램을 PIP로 표시할 수 있는 픽쳐-인-픽쳐시스템에서 미리 설정된 예약 시간에 예약된 채널의 프로그램을 자동으로 PIP의 자화면을 표시하는 픽쳐-인-픽쳐 시스템에서의 예약 프로그램 자동 표시회로 및 방법에 관한 기술이다. 상기 예약 프로그램 자동표시회로는 동작 제어신호 및 채널선택 데이터의 입력에 응답하여 수신되는 전파신호 중 해당 채널의 영상신호를 선택복조하여 출력하는 제1,제2 영상신호 선택처리수단과, 상기 제1영상신호 선택처리수단으로부터 출력되는 영상신호를 표시영상으로 출력하고, 표시제어 데이터의 입력에 응답하여 상기 제1,제2 영상신호 선택처리수단으로부터 각각 출력되는 영상신호를 PIP신호 처리하여 PIP표시 영상신호로 출력하는 PIP신호 처리수단과, 제어신호의 입력 상태를 분석하여 예약시간과 예약채널을 내부의 레지스터에 설정하고, 상기 예약된 시간에 상기 제2영상신호 선택 처리수단에 동작제어 신호 및 채널 선택 데이터를 공급함과 동시에 표시제어데이터를 상기 PIP신호처리수단을 포함하여 가진다.Picture-in-Picture system that can display broadcast program received with at least one tuner as PIP Automatically display PIP sub-screen of program of reserved channel at preset reservation time in picture-in-picture system An automatic display circuit and a method for a reservation program in. The reservation program automatic display circuit includes first and second video signal selection processing means for selectively demodulating and outputting a video signal of a corresponding channel among radio signals received in response to an operation control signal and channel selection data input; Outputs the video signal output from the video signal selection processing means to the display video, and processes the video signal output from the first and second video signal selection processing means in response to the input of the display control data to process the PIP signal. PIP signal processing means for outputting a signal and an input state of a control signal are analyzed to set a reservation time and a reservation channel in an internal register, and at the reserved time, an operation control signal and a channel to the second video signal selection processing means. In addition to supplying selection data, display control data is included, including the PIP signal processing means.
