Abstract

본 발명은 현재재생중인 테이프의 신호유무를 트랙킹에러 신호를 이용하여 판별하기에 적당하도록 한 트랙킹에러 신호에 의한 테이프의 신호유무 판별장치에 관한 것으로 RF신호의 완충작용을 하는 버퍼(2), 버퍼(2)의 신호와 마이컴의 신호(SEL1)(SEL2)를 이용하여 트랙킹에러 신호를 발생하는 트랙킹에러신호발생부(3), 캡스턴 모터를 제어하는 캡스턴모터위상제어부(6), 트랙킹에러 신호를 이용하여 신호 유무를 판별하는 소프트웨어신호유무판별부(10), 캡스턴모터 위상제어 여부를 결정하는 캡스턴모터위상제어 온/오프부(7), 리얼타임 카운터 진행 여부를 결정하는 리얼타임카운터진행 온/오프부(8), 우신호시 오디오, 비디오 뮤트신호를 발생하는 오디오, 비디오뮤트신호발생부(9)를 포함하여 이루어진다.The present invention relates to an apparatus for discriminating whether a tape is present by a tracking error signal that is suitable for discriminating whether or not a signal of a tape currently being played by using a tracking error signal is provided. The tracking error signal generation unit 3 for generating a tracking error signal using the signal (2) and the signals SEL1 and SEL2 of the microcomputer, the capstan motor phase control unit 6 for controlling the capstan motor, and the tracking error signal Software signal discrimination unit 10 for determining the presence or absence of a signal, capstan motor phase control on / off unit 7 for determining whether to control the capstan motor phase, and real time counter progress on / off for determining whether the real-time counter is in progress It comprises an off section 8, an audio and video mute signal generator 9 for generating audio and video mute signals at the right signal.
