Abstract

본 발명은 TV모드시 비디오 신호 확인방법에 관한 것으로, 제어기능의 설정을 제어신호입력부(10)와,이 제어신호입력부(10)에 구비된 버튼 조작에 대응하는 제어를 수행하는 제어부(12), 영상/음성IF모듈(22,24)에서 인가된 영상/음성 신호와 비디오/오디오신호입력단자(26a,26b)를 통해 입력되는 비디오/오디오신호에 대한 스위칭동작을 수행하는 A/V스위칭부(26) 및 , 상기 A/V스위칭부(26)로부터 출력된 영상신호를 상기 제어부(12)로부터 출력된 제어신호를 근거로 다화면처리하여 CRT장치(32)상으로 출력하는 영상처리수단(28,30)을 구비하여 구성된 텔레비젼에 있어서, TV모드에서 방송신호를 재생하고 있는 도중에 상기 제어 신호입력부(10)의 VCR확인버튼(10b)이 조작되어지면 주화면으로는 비디오신호를 출력하고, 부화면으로는 방송신호를 출력하며, 소정시간내에 상기 제어신호입력부(10)의 모드설정버튼(10a)이나 VCR확인버튼(10b)이 조작되어지지 않으면 정규의 TV방송신호에 대한 영상신호만을 상기 CRT장치(32)상으로 화면출력하다가 동기신호검출부(40)에서 상기 비디오신호의 동기신호가 검출되면 검출된 시점부터 일정시간 간격으로 재생중인 비디오신호를 주화면으로 출력하고 부화면으로는 방송신호를 출력할 수 있도록 하는 것이다.The present invention relates to a method for checking a video signal in a TV mode, wherein a control function for setting a control function is performed by a control signal input unit (10) and a control corresponding to a button operation provided in the control signal input unit (10). , A / V switching unit for switching video / audio signals applied from video / audio IF modules 22 and 24 and video / audio signals input through video / audio signal input terminals 26a and 26b. (26) and image processing means for outputting the image signal output from the A / V switching unit 26 onto the CRT device 32 by multi-screen processing on the basis of the control signal output from the control unit 12 ( 28 and 30. In a television comprising 28 and 30, if the VCR confirmation button 10b of the control signal input unit 10 is operated while the broadcast signal is being reproduced in the TV mode, a video signal is output to the main screen. Broadcast signal is outputted on the sub-screen, and within a predetermined time If the mode setting button 10a or the VCR confirmation button 10b of the control signal input unit 10 is not operated, only a video signal for a regular TV broadcast signal is output on the CRT device 32 and then the synchronization signal detection unit When the synchronization signal of the video signal is detected at 40, the video signal being reproduced at a predetermined time interval from the time point of detecting the video signal is output on the main screen and the broadcast signal is output on the sub-screen.

Claims

The control function is set by the control signal input unit 10, the control unit 12 and the video / audio IF modules 22 and 24 which perform the control corresponding to the button manipulation provided in the control signal input unit 10. An A / V switching unit 26 for switching the video / audio signal input through the video / audio signal and the video / audio signal input terminals 26a and 26b, and the A / V switching unit 26 A television comprising a video processing means (28, 30) for multi-screen processing on a video signal output from the control unit (12) based on a control signal output from the control unit (12) and outputting the video signal onto a CRT device (32). If the VCR confirmation button 10b of the control signal input unit 10 is operated while the broadcast signal is being reproduced at, the video signal is output on the main screen and the broadcast signal is output on the sub-screen. Checking the mode setting button 10a or the VCR of the control signal input unit 10 If the button 10b is not operated, only the video signal for the regular TV broadcast signal is output on the CRT device 32, and when the sync signal detection unit 40 detects the sync signal of the video signal, A video signal checking method in a TV mode, characterized by outputting a video signal being reproduced at regular intervals to a main screen and a broadcast signal to a sub screen.
