Abstract

본 발명은 비디오 카세트 레코더(이하는 VCR이라 칭함)의 재생동작 제어방법에 관한 것으로서 보다 상세하게는 비디오 테이프에 기록되어 있는 녹화 시작신호를 탐색하여 신호 유/무에 따라 모터 구동수단을 제어함으로써 재생시 녹화시작 지점을 찾아내기 위해 시행하는 불필요한 시행착오없이 비디오 테이프 녹화시작 시점에서부터 자동으로 재생동작을 실시할 수 있는 재생동작 제어방법에 관한 것이다.The present invention relates to a method of controlling a playback operation of a video cassette recorder (hereinafter referred to as a VCR). More particularly, the present invention relates to playback by searching a recording start signal recorded on a video tape and controlling the motor driving means according to the presence / absence of a signal. The present invention relates to a playback operation control method capable of automatically performing a playback operation from a video tape recording start point without unnecessary trial and error performed to find a recording start point.

특징적인 구성으로는 VCR의 키입력수단에서 테이프 재생버튼이 눌러지면 영상신호 처리수단으로부터 재생되어 들어오는 신호를 체크하는 제1단계와, 상기 제1단에서 체크신호가 있을 경우는 정상적인 재생동작을 수행하도록 모터 구동수단을 제어하고 체크신호가 없을 경우는 빨리감기 동작을 수행하도록 모터 구동수단을 제어하면서 릴감지수단으로부터 감지신호를 읽어들여 녹화시작신호가 입력되는지를 체크하는 제2단계와, 상기 제2단계에서 녹화 시작신호가 체크될때까지 빨리감기 동작을 계속하도록 모터 구동수단을 제어하면서 녹화시작신호가 검출되면 그 시점에서부터 정상적인 재생동작을 개시하도록 모터 구동수단을 제어하는 제3단계로 이루어짐에 있다.As a characteristic configuration, when the tape play button is pressed on the key input means of the VCR, the first step of checking the signal received from the video signal processing means is performed, and when there is a check signal at the first end, the normal play operation is performed. A second step of checking whether a recording start signal is input by reading a detection signal from the reel detecting means while controlling the motor driving means so as to control the motor driving means and performing a fast forwarding operation when there is no check signal; In step 2, the motor driving means is controlled to continue the fast-forward operation until the recording start signal is checked, and when the recording start signal is detected, the motor driving means is controlled to start the normal playback operation from that point. .

Claims

When the tape play button is pressed by the key input means of the VCR, the first step of checking the signal received from the video signal processing means, and the motor driving means to perform normal play operation when there is a check signal in the first step. In the second step of controlling the motor driving means to perform the fast-winding operation when there is no check signal and checking whether the recording start signal is input by reading the detection signal from the reel detection means, and starting the recording in the second step. And a third step of controlling the motor drive means to start the normal playback operation from that time point when the recording start signal is detected while controlling the motor drive means to continue the fast forward operation until the signal is checked. How to control the playback operation.
