Abstract

본 발명은 비디오 카세트 레코더(VIDEO CASSETTE RECORDER)의 녹화 방법에 관한 것으로서, 특히, 라인 녹화시 재생용 테이프에 기록된 영상 신호만을 녹화용 테이프에 기록하는 브이씨알의 녹화 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a recording method of a video cassette recorder, and more particularly, to a recording method of V-CAL which records only a video signal recorded on a playback tape in a line recording.

이를 위하여 본 발명은, 재생용 비디오 카세트 레코더에서 출력되는 동기 신호에 따라 녹화용 비디오 카세트 레코더가 선택적으로 라인 녹화하는 방법으로서, 재생용 비디오 카세트 레코더에서 영상 신호가 재생되는가를 판단하기 위한 소정의 재생 판단 시간을 설정하는 신호가 입력되는가를 판단하는 제1단계(200); 소정의 재생판단 시간 설정 신호가 입력되었으면 플레이 모드로 구동하는가 판단하는 제2단계(201); 플레이 모드로 구동하면 동기 신호가 검출되는가를 판단하는 제3단계(202); 동기 신호가 검출되면 제2단계로 귀환하고, 동기 신호가 검출되지 않으면 동기 신호가 검출되지 않은 테이프 주행시간부터 설정된 소정의 재생 판단 시간까지 카운트하는 제4단계(203); 카운트한 시간과 설정된 소정의 재생 시간이 같은가를 판단하는 제5단계(204); 카운트한 시간과 설정된 소정의 재생 판단 시간이 같지 않으면 플레이 모드로 계속 구동하고, 카운트한 시간과 설정된 소정의 재생 판단 시간이 같으면 정지 모드로 변환한 후 전원을 오프시키는 제6단계(205, 206)를 포함하여 구성되므로써, 녹화시 발생하는 시간 낭비 및 전력 소모를 방지하는 효과가 있다.To this end, the present invention provides a method of selectively recording a line in a video cassette recorder according to a synchronization signal output from a video cassette recorder for reproducing a predetermined reproduction for determining whether a video signal is reproduced in a video cassette recorder for reproduction. A first step 200 of determining whether a signal for setting a determination time is input; A second step 201 of determining whether to drive in a play mode when a predetermined playback determination time setting signal is input; A third step 202 of determining whether a synchronization signal is detected when driving in the play mode; A fourth step (203) when the synchronization signal is detected, and returns to the second step, and when the synchronization signal is not detected, counting from the tape running time at which the synchronization signal is not detected to a predetermined reproduction determination time; A fifth step (204) of determining whether the counted time and the predetermined predetermined reproduction time are the same; If the counted time and the predetermined predetermined playback determination time are not the same, the operation continues in the play mode. If the counted time and the predetermined predetermined playback determination time are the same, the sixth step (205, 206) is switched to the stop mode and the power is turned off. Since it is configured to include, there is an effect of preventing time wastage and power consumption during recording.

Claims

A method of selectively line-recording a video cassette recorder in accordance with a synchronization signal output from a video cassette recorder for reproducing, wherein a predetermined playback determination time for determining whether a video signal is reproduced in the video cassette recorder is set. A first step 200 of determining whether a signal is input; A second step (201) of determining whether to drive in a play mode when the predetermined play determination time setting signal is input; A third step (202) of determining whether the synchronization signal is detected when driving in the play mode; A fourth step (203) of returning to the second step if the synchronization signal is detected, and counting from the tape running time at which the synchronization signal is not detected to the predetermined predetermined playback determination time if the synchronization signal is not detected; A fifth step (204) of determining whether the counted time is equal to the set predetermined reproduction time; A sixth step of continuing to drive to the play mode if the counted time and the predetermined predetermined playback determination time are not the same; and switching to a stop mode if the counted time and the predetermined predetermined playback determination time are the same; And (205, 206).
