Abstract
본 발명은 비디오 카세트 레코더에 관한 것으로서, 특히 비디오 카세트 레코더에서 오디오/비디오 회로부와 서보구동부를 분리 동작되게 하여 사용자가 재생도중 TV방송신호를 탐색할 수 있도록 한 재생도중 방송신호 탐색방법 및 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video cassette recorder, and more particularly, to a method and apparatus for searching for a broadcast signal during playback, which allows a user to search for a TV broadcast signal during playback by allowing an audio / video circuit unit and a servo driver to be separately operated. will be.
TV탐색 모드를 선택 할 수 있는 키가 선택되면 키 입력 신호를 마이 콤(20)에 전달하는 키 입력부(10)와, 각 구성을 프로그램에 의해 동작되게 제어하는 마이콤(20)과, 안테나를 통하여 전달되는 방송신호를 수신하여 상기 마이콤(20)의 제어신호에 의하여 방송신호를 선택회로부(70)로 출력하는 튜너/IF회로부(30)와, 상기 마이콤(20)의 제어신호에 의하여 TV방송모드 또는 라인모드로 전환되게 하는 선택회로부(70)와, 상기 마이콤(20)의 출력신호에 의해 구동되어 테크부(60)의 동작을 제어하는 서보구동부(50)와, 상기 서보구동부(50)의 제어신호에 의해 동작되는 테크부(60)와, 상기 마이콤(20)의 출력신호에 의해 구동되어 선택회로부(80)의 출력신호를 전달받아 방송신호 또는 라인신호를 표시부(90)로 출력하는 오디오/비디오 회로부(80)와, 상기 오디오/비디오 회로부(80)의 출력신호를 전달받아 화면에 디스플레이하는 표시부(90)를 포함하는 것으로서 비디오 카세트 레코더 재생중에 TV방송신호를 탐색할 수 있는 기술에 관한 것이다.When a key for selecting a TV search mode is selected, a key input unit 10 for transmitting a key input signal to the microcomputer 20, a microcomputer 20 for controlling each component to be operated by a program, and an antenna A tuner / IF circuit unit 30 which receives the transmitted broadcast signal and outputs the broadcast signal to the selection circuit unit 70 according to the control signal of the microcomputer 20, and the TV broadcast mode according to the control signal of the microcomputer 20. Or the selection circuit unit 70 for switching to the line mode, the servo driver 50 driven by the output signal of the microcomputer 20 to control the operation of the tech unit 60, and the servo driver 50. Audio which is driven by a tech unit 60 operated by a control signal and an output signal of the microcomputer 20 and receives an output signal of the selection circuit unit 80 and outputs a broadcast signal or a line signal to the display unit 90. / Video circuitry 80, and the audio / video circuit Receiving an output signal (80) will as including a display unit 90 for display on the screen to a technique to navigate through the TV broadcast signal while playing a video cassette recorder.
