Description

텔레비전의 채널 선택회로TV channel selection circuit

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

제3도는 본 발명의 회로도,3 is a circuit diagram of the present invention,

제4도는 본 발명의 마이콤의 내장된 프로그램의 흐름도.4 is a flowchart of a built-in program of the microcomputer of the present invention.

Claims (1)

텔레비전 채널선택회로에 있어서 리모콘(R)과 키(K)를 가변저항(1)으로 대치하고 이 가변저항(1)의 출력 신호를 입력으로하는 교류/직류 변환기(2)를 연결하며 이 교류/직류 변환기(2)의 출력단자에 마이콤(M)을 연결하는데 이 마이콤(M)에는 입력된 교류/직류 변환기(2)의 출력 신호를 레지스터(A)에 저장하고 과거의 입력된 교류/직류 변환기(2)의 출력신호와 비교한후 같으면 가변저항(1)의 변경이 없으므로 종료하고 다르면 현재 입력된 교류/직류 변환기(2)의 출력신호에 따라 문자를 출력하고 일정시간 지연후 다시 교류/직류 변환기(2)의 출력신호를 입력하여 레지스터(A)에 저항하고 이 저항된 레지스터(A)의 데이터가 문자출력중인 데이터와 비교 같으면 채널변경이 없으므로 계속 출력중인 데이터를 출력시키며 다르면 채널이 변경 되었으므로 변경된 채널의 데이터를 출력하고 이 변경된 채널의 문자를 출력하도록 제어하는 프로그램이 내장됨을 특징으로 하는 텔레비젼의 채널 선택회로.In the television channel selection circuit, the remote controller R and the key K are replaced with the variable resistor 1, and an AC / DC converter 2 for inputting the output signal of the variable resistor 1 is connected. The microcomputer (M) is connected to the output terminal of the direct current converter (2). The microcomputer (M) stores the output signal of the input AC / DC converter (2) in the register (A) and inputs the input AC / DC converter of the past. After comparing with the output signal of (2), if it is the same, there is no change of the variable resistor (1). Since the output signal of the converter 2 is inputted and resisted to the register A and the data of the resisted register A is the same as the data being outputted, the channel is not changed. Changed The data output and channel selection of the television, characterized in that the built-in program for controlling to output a character of the changed channel circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
