Abstract

본 발명은 멀티 A/V신호 입력을 선택하는 멀티 입력 모우드 절환 회로에 관한 것으로, 기존 멀티 입력 A/V기기가 A/V신호 입력이 많을 경우 순차적으로 원하는 모우드를 선택하게 되어 모우드 선택에 불편이 따르게 된다.The present invention relates to a multi-input mode switching circuit for selecting a multi-A / V signal input, when the existing multi-input A / V device has a large number of A / V signal input sequentially selects the desired mode is inconvenient to the mode selection Will follow.

따라서 S-Video 입력잭에 내부 스위치를 설치하고 상기 내부 스위치 접속을 A/V스위치 IC에서 인식하여 비데오 신호와 S-Video신호를 입력중 S-Video신호를 우선하여 선택하며 선택된 A/V신호를 모우드 선택키 입력에 따른 마이콤의 제어신호에 의해 순차적으로 선택하여 출력시키도록 하므로써 간단히 다중 입력 A/V신호중 S-Video신호를 우선하여 원하는 모우드를 선택할수 있다.Therefore, the internal switch is installed in the S-Video input jack, the internal switch connection is recognized by the A / V switch IC, and the video signal and the S-Video signal are selected in priority, and the selected A / V signal is selected. Mode selection key You can select the desired mode by prioritizing S-Video signal among multiple input A / V signals by selecting and outputting sequentially by the control signal of micom according to input.
