Abstract
이 발명은 텔레비젼의 잭 스위칭 방법 및 그 장치에 관한 것으로서, 비데오 신호 처리부로부터 출력되는 신호상의 동기신호 검출을 위한 동기 검출부와, 동기 검출부의 동기신호 검출결과에 따라 제어신호를 출력하는 제어부와, 제어신호에 의하여 잭들과 비데오 신호 처리부 및 오디오 신호 처리부의 연결상태를 스위칭하는 스위치들과, 제어부로부터 입력되는 데이타에 의하여 온 스크린 디스플레이 신호를 발생시켜 비데오 신호 처리부로 인가하는 온 스크린 디스플레이 신호 발생부가 구성되어서, 사용자가 비데오 신호 입력 잭 및 오디오 신호 입력잭을 외부 기기로부터 비데오 신호 및 오디오 신호가 입력되는 케이블을 잘못 접속하였을 때 이를 인지하여 자동으로 스위칭 동작을 수행하고 또 사용자가 연결이 잘못되었음을 알리기 위한 잭 연결상태 체크 메세지를 디스플레이시킴으로써 텔레비젼을 사용함에 있어서 사용자에게 편이함을 제공할 수 있는 효과가 있다. 이것은 모든 텔레비젼의 신호 입력용 잭의 구성에 이용 가능하다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jack switching method and apparatus of a television, comprising: a synchronization detecting unit for detecting a synchronization signal on a signal output from a video signal processing unit, a control unit for outputting a control signal in accordance with a synchronization signal detection result of the synchronization detection unit, and control; A switch for switching the connection state of the jacks, the video signal processor and the audio signal processor by a signal, and an on-screen display signal generator for generating an on-screen display signal by data input from the controller and applying the signal to the video signal processor. When the user incorrectly connects the video signal input jack and audio signal input jack from the external device to the video signal and audio signal input cable, it recognizes this and performs the switching operation automatically. Connection There is an effect that can provide a convenience to the user in using the television by displaying a check message. This is available for the configuration of jacks for signal input of all televisions.
