Abstract

본 발명은 텔레비젼 "온"시 또는 해당키이 신호입력시 외부기기의 접속상태를 판별하여 접속된 외부기기의 신호를 차례로 디스플레이해주는 텔레비젼의 외부기기 연결상태 자동안내 장치에 관한 것이다. 본 발명의 장치는 외부입력단자를 통해 입력되는 외부기기 신호중 어느 하나의 신호를 선택하기 의한 스위칭 회로부와, 상기 외부입력단자에접속된 외부기기를 판별하고, 접속된 외부기기신호들을 순차적으로 화면에 디스플레이시키도록 상기 스위칭회로부를 스위칭제어하는 마이크로 컴퓨터를 포함한다.The present invention relates to an apparatus for automatically guiding a connection state of an external device of a television which determines a connection state of an external device when the television is "on" or when a corresponding key signal is input and sequentially displays a signal of the connected external device. The apparatus of the present invention determines a switching circuit unit for selecting any one of an external device signal input through an external input terminal, an external device connected to the external input terminal, and sequentially displays the connected external device signals on a screen. And a microcomputer for switching control of said switching circuitry to display.
