Abstract

본 발명은 멀티 비디오 입력단자를 통해 입력되는 각 비디오 신호와 멀티 사운드 입력단자를 통해 들어오는 각 사운드 신호를 사용자가 필요에 따라 원하는 비디오모드와 원하는 사운드모드를 별도로 선택하여 모니터 및 스피커로 출력되도록 함으로써, 원하는 기능을 필요시마다 효율적으로 구현할 수 있도록 한 멀티 비디오/사운드 선택장치 및 제어방법에 관한 것으로, 스위치 조작부(1)에 구비된 사운드 선택스위치(1a)와, 상기 비디오 선택 스위치(1b)의 종류와 함께 상기 사운드 선택스위치(1a)의 종류를 각각 종류별로 CRT(7)에 디스플레이할 수 있도록 구현한 OSD(11)와, 마이컴(3)의 제어에 의해 비디오 입력과 사운드 입력이 별도로 선택될 수 있도록 한 멀티플랙서부(4)와, 상기 스위치 조작부의 비디오 선택스위치와 사운드 선택스위치가 입력되면 이를 인식하여 상기 멀티플렉서부(4)를 제어하기 위한 마이콤(3)으로 구성된다.According to the present invention, the user selects a desired video mode and a desired sound mode separately for each video signal input through the multi video input terminal and each sound signal input through the multi sound input terminal, and outputs them to the monitor and the speaker. The present invention relates to a multi video / sound selection device and a control method for efficiently implementing a desired function whenever necessary. The present invention relates to a sound selection switch (1a) provided in the switch operating unit (1), and a type of the video selection switch (1b). In addition, the OSD 11 implemented to display the types of the sound selection switch 1a on the CRT 7 for each type and the video input and the sound input can be separately selected by the control of the microcomputer 3. When the multiplexer section 4, the video selection switch and the sound selection switch of the switch operation section are inputted, Recognized consists of a microcomputer (3) for controlling the multiplexer unit 4.
