Abstract

본 발명은 텔레비전 온/오프타임의 설정시 PIP화면 제어장치에 관한 것으로, 메인채널의 영상신호에 대한 영향을 최소화한 상태에서 온/오프타임의 설정을 위한 PIP화면이 정의되도록 하기 위해, 상기 온/오프타임의 설정을 위한 제어신호를 입력하는 리모콘(10)과, 상기 영상신호의 수평/수직동기신호를 검출하는 수평/수직동기신호검출부(28), 상기 검출된 수평/수직동기신호를 카운트하여 소정의 카운트치에 도달되면 카운트결과를 발생하는 카운트수단(30), 상기 소정의 카운트치에 대한 카운트결과에 기초하여 영상다중처리부(20)에 영상신호에 대한 블랭킹처리를 제어함과 더불어 상기 온/오프타임의 설정을 위한 화면표시를 제어하는 제어수단(12), 그 제어부(12)의 제어하에 상기 온/오프타임의 설정을 위한 OSD신호를 생성해서 상기 영상다중처리부(20)에 인가하는 OSD처리부(26)를 구비하여 구성되고, 상기 영상신호의 수직블랭킹기간에 전송되는 BPS코드를 검출하는 BPS코드검출부(32)가 부가되거나 상기 영상신호의 휘도/콘트라스트의 레벨을 검출하는 휘도/콘트라스트레벨검출(34)부가 더 구비되어 구성된 것이다.The present invention relates to a PIP screen control apparatus for setting a television on / off time, in order to define a PIP screen for setting on / off time in a state in which the influence on the video signal of the main channel is minimized. A remote controller 10 for inputting a control signal for setting the on / off time, a horizontal / vertical synchronous signal detector 28 for detecting a horizontal / vertical synchronous signal of the video signal, and counting the detected horizontal / vertical synchronous signal And counting means 30 for generating a count result when the predetermined count value is reached, and controlling the blanking process for the video signal on the image multiple processor 20 based on the count result for the predetermined count value. Control means 12 for controlling the display of the screen for setting the on / off time, under the control of the control unit 12 generates the OSD signal for setting the on / off time by the image multiple processing unit 20 And an OSD processing section 26 for applying a signal to the video signal, and a BPS code detection section 32 for detecting a BPS code transmitted in the vertical blanking period of the video signal is added or for detecting the level of brightness / contrast of the video signal. The luminance / contrast level detection unit 34 is further provided.
