Abstract

본 발명은 디지탈 오디오 광입출력단자를 이용하여 원신호의 열화없이 오디오 신호 유무를 검출하여 자동으로 출력을 절환시켜 주도록 한 자동 오디오 선택장치에 관한 것이다.The present invention relates to an automatic audio selection device that detects the presence of an audio signal without deterioration of an original signal using a digital audio light input / output terminal and automatically switches output.

본 발명은 종래 사용자가 직접 수동으로 출력을 절환하던 불편함을 감안하여 수동모드나 자동모드를 선택하는 모드선택키 및 수동모드시 입력을 직접선택하여 입력선택키등이 위치하는 키입력수단, 입력신호의 유무를 검출하는 신호검출수단, 입력들중 하나를 출력하는 스위칭수단, 상기 키입력수단의 키입력을 감지하여 자동모드일 경우 상기 신호검출수단의 신호검출유무에 따라 그리고 수동모드일 경우 입력선택키 입력에 따라 상기 스위칭수단의 제어하는 마이컴, 상기 마이컴의 제어에 따라 현재 신호가 입력되는 단자 및 출력으로 선택된 단자를 표시하여 주는 표시수단을 구비하여 원신호의 열화없이 오디오 신호 유무를 검출하여 자동으로 출력이 절환되도록 하며, 현재 신호가 입력되는 단자 및 출력으로 선택된 단자를 알려주도록 한 것이다. 그리고 본 발명은 디지탈 오디오 광입출력단자를 갖는 오디오 기기의 신호절환을 위한 오디오 선택장치에 적용가능하다.In the present invention, in consideration of the inconvenience of manually switching the output manually, a mode selection key for selecting a manual mode or an automatic mode and a key input means in which an input selection key is positioned by directly selecting an input in a manual mode, an input is performed. A signal detecting means for detecting the presence of a signal, a switching means for outputting one of the inputs, a key input of the key input means to detect a key input according to whether or not the signal detecting means detects a signal, and in a manual mode A microcomputer for controlling the switching means according to a selection key input, and a display means for displaying a terminal to which a current signal is input and an output according to the control of the microcomputer to detect the presence or absence of an audio signal without deterioration of the original signal. To automatically switch the output, and to inform the terminal that the current signal is input . The present invention is also applicable to an audio selection device for signal switching of an audio device having a digital audio light input / output terminal.
