음성다중 방송용 매트릭스부 제어장치Matrix control unit for voice multicasting

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 회로도.1 is a circuit diagram of the present invention.

Claims (1)

음성다중방성 수신장치의 매트릭스부를 제어하는 것에 있어서, 방송상태의 변화를 감지하는 방송상태변화 감지회로부(1)의 출력(D0)은 사용자 선택키이를 누를 때 발생하는 채터링 방지용 수미트 트리거회로(2)의 출력에 의해 트리거되는 단안정 멀티바이브레타(3)의 트리거 입력(A0)에 연결하되 단안정 멀티바이브레타(3)의 출력(B0)에서는 뮤팅펄스가 출력되도록 하고, 출력(B1,B2)은 각각 상태변화감지회로부(1)의 입력(I0)과 사용자가 원하는 방송수신 모드의 선택상태 기억회로부(4) 입력(E0)에 연결하고, 방송상태변화 감지회로부(1)의 출력(D1,D2)은 사용자 모드선택상태 기억회로부(4)의 입력(E1)과 디코더(5)의 입력(G0)에 각각 연결하며, 디코더(5)의 다른 입력(G1)은 방송상태변화감지회로부(4)의 출력(F0)에 연결하되 그 출력(H0)은 스위치부(6) 일측에 연결하여 화면표시용 마이크로프로세서로부터 정보를 받는 마이크로프로세서인터페이스부(7)의 출력과 스위치부(6)에서 전환되도록하고, 스위치부(6)의 출력은 디코더(8)을 통해 입력음성신호(IN0,IN1)를 디코더(8)출력에 따라 좌측음성신호(L)와 우측음성신호(R)를 출력하는 매트릭 부(9)에 연결하여서 된 음성다중 방송용 매트릭스부 제어장치.In controlling the matrix unit of the voice multiplex receiver, the output D 0 of the broadcast state change detection circuit unit 1 for detecting a change in broadcast state is a summit trigger circuit for preventing chattering generated when a user select key is pressed. Connect to the trigger input (A 0 ) of the monostable multivibrator (3) triggered by the output of (2), but output the muting pulse at the output (B 0 ) of the monostable multivibrator (3), and output (B 1 , B 2 ) are connected to the input (I 0 ) of the state change detection circuit unit 1 and the selected state memory circuit unit (4) input (E 0 ) of the broadcast reception mode desired by the user, respectively, to detect the change in broadcast state. The outputs D 1 and D 2 of the circuit part 1 are connected to the input E 1 of the user mode selection state memory circuit part 4 and the input G 0 of the decoder 5, respectively, the other input (G 1), but is coupled to the output (F 0) of the broadcast state change detection circuit (4) and the output (H 0) is switch (6) It is connected to one side so that the output of the microprocessor interface unit 7 which receives information from the display microprocessor and the switch unit 6 are switched, and the output of the switch unit 6 is connected through the decoder 8 Control apparatus for voice multicasting matrix unit by connecting the input voice signals IN 0 and IN 1 to the metric unit 9 which outputs the left voice signal L and the right voice signal R in accordance with the decoder 8 output. . ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
