Abstract

본 발명은 외부 비디오 기기를 통해 비디오 신호가 입력되는 경우에 자동으로 PIP가 턴-온되어 비디오 신호가 부화면으로 화면표시 장치에 출력되도록 한 기능을 갖도록 하기 위해서 외부 비디오 기기에서 입력되는 영상신호와 음성신호를 처리하는 비디오 신호 처리부와, 텔레비전 방송신호의 영상신호와 음성신호를 처리하는 텔레비전 신호 처리부와, 사용자가 입력하는 키 입력에 따라 상기 처리부들을 제어하는 마이콤과, 상기 처리부들에서 출력되는 영상신호 중 하나를 주화면으로 처리하는 주영상신호 처리부와, 부화면으로 처리하는 PIP(Picture In Picture) 신호 처리부를 구비하는 PIP 텔레비전에 있어서, 상기 비디오 영상신호에서 동기신호를 검출하는 동기신호 검출부를 포함하여 상기 마이콤은 상기 동기신호 검출부의 신호에 따라 상기 비디오 영상신호를 PIP 신호처리부로 입력하는 것을 특징으로 하는 PIP 텔레비전을 제공한다.The present invention provides a video signal input from an external video device to have a function of automatically turning on the PIP when the video signal is input through an external video device so that the video signal is output to the display device as a sub-screen. A video signal processor for processing audio signals, a television signal processor for processing video signals and audio signals of a television broadcast signal, a microcomputer for controlling the processors according to a key input input by a user, and images output from the processors A PIP television comprising a main video signal processing unit for processing one of the signals as a main picture and a PIP (Picture In Picture) signal processing unit for processing as a sub picture, the sync signal detecting unit detecting a sync signal from the video video signal; The microcomputer includes the video according to the signal of the synchronization signal detector. To input the image signal to the PIP signal processing unit provides a PIP television as claimed.
