Abstract

본 발명은 복수의 외부입력 라인이 설치된 TV에서 최소의 키조작을 통하여 원하는 비디오 모드를 선택할 수 있는 방법에 관한 것이다.The present invention relates to a method for selecting a desired video mode through a minimum key operation on a TV equipped with a plurality of external input lines.

지금까지는 다수의 외부입력 라인을 가지는 TV에서 외부입력 선택시 기계적으로 정해진 순서대로 선택되기 때문에 불필요한 키잉조작을 반족수행하지 않으면 안되었다.Until now, TVs with multiple external input lines have been selected in order of mechanical selection for external input selection, so that unnecessary keying operations have to be performed.

본 발명은 각 외부입력 라인을 모니터하여 먼저 동기신호 검출되는 라인만 순차 로테이션 방식으로 선택되게 하고, 다음은 A/V 케이블이 연결된 외부입력 라인만 순차 로테이션 되게 하고, 나중에 외부입력 케이블도 연결되어 있지 않은 조건에서는 기존의 방식대로 기계적인 수서에 따라 외부입력이 선택되게 한다.The present invention monitors only the external input lines and sequentially selects only the lines that are detected as synchronous signals, and then turns on only the external input lines to which the A / V cable is connected, and then the external input cables are also connected The external input is selected according to the mechanical procedure in the conventional manner.

이에 따라 외부입력 선택 조작시 키이 횟수를 줄일 수 있어 TV 사용이 편리해진다.As a result, the number of keystrokes can be reduced during the operation of selecting an external input, thereby facilitating the use of the TV.
