Abstract

본 발명은 외부로부터 입력되는 오디오 신호와 비디오 신호가 텔레비젼이 외부 입력단자와 올바르게 접속되었는가를 판단하여 이를 CRT상에 나타내주므로써, 사용자가 외부 입력단를 올바르게 접속할 수 있도록 된 A/V 시스템용 텔레비젼의 입출력단자의 접속판별장치에 관한 것으로서, 외부로부터 발생된 영상 음향신호가 입력될 수 있도록 하는 외부 영상신호 입력단자와 음향신호 입력단자 및 이 외부 영상/음향 입력단자로부터 입력되는 영상 음향신호와 안테나로부터 입력되는 영상 음향신호 중 하나를 스위칭 선택하는 스위칭선택수단을 구비하고, 이 스위칭 선택수단에 의해 선택된 영상 음성신호를 CRT나 스피커로 출력하도록 된 A/V용 텔레비젼에 있어서, 상기 스위칭 선택수단의 선택이 외부 입력단자로부터 입력되는 영상 음향신호의 선택일 때 상기 외부 음향입력단자로 입력되는 신호로부터 동기신호를 검출하는 동기신호 검출수단과, 상기 동기검출수단의 동시신호 검출 결과를 CRT 상에 표시하는 표시수단 및, 상기 동시신호검출수단의 동기신호검출 유무에 따라 상기 표시수단을 제어하는 제어수단으로 구성된 것을 특징으로 한다.According to the present invention, an audio signal and a video signal input from the outside determine whether the television is properly connected to an external input terminal, and display it on a CRT, thereby allowing the user to connect the external input terminal correctly. A terminal discrimination apparatus, comprising: an external video signal input terminal and an audio signal input terminal for inputting an external video audio signal, and a video audio signal and an antenna input from the external video / audio input terminal. A / V television having switching selection means for switching and selecting one of the video sound signals to be output, wherein the selection of the switching selection means is performed in the A / V television configured to output the video and audio signal selected by the switching selection means to a CRT or a speaker. Selection date of video sound signal input from external input terminal Synchronization signal detection means for detecting a synchronization signal from the signal input to the external sound input terminal, display means for displaying the simultaneous signal detection result of the synchronization detection means on a CRT, and whether the synchronization signal detection means is present or not The control means for controlling the display means according to.
