Abstract

본 발명은 비디오 테이프 종류 자동판별방법에 관한 것으로서, 여러 종류의 비디오 테이프를 재생하는 경우, 신경회로망 알고리즘을 이용하여 해당 비디오 테이프의 충재생시간을 자동으로 판별하도록 함과 동시에, 자동 판별된 해당 비디오 테이프의 총재생시간에 따라, 해당 비디오 테이프 레코더의 재생시간을 자동으로 세팅하도록 하기 위하여, 비디오 테이프의 종류를 판별하는 방법에 있어서, 현재 주행중인 비디오 테이프로부터 릴의 회전변화량을 검출하는 제1과정; 릴이 1회전하는 동안에 캡스턴모터 주파수발생기로부터 출력되는 펄스수를 순차적으로 검출하는 제2과정; 및 상기 제2과정에서 검출된 펄스수를 신경회로망 알고리즘에 입력시켜 비디오 테이프의 종류를 판별하는 제3과정을 수행하도록 하였다.The present invention relates to a video tape type automatic discrimination method and, in the case of reproducing various kinds of video tapes, it is possible to automatically determine a recharging time of a corresponding video tape by using a neural network algorithm, A method for determining a type of a video tape in order to automatically set a reproduction time of the video tape recorder in accordance with a total reproduction time of the tape, ; A second step of sequentially detecting the number of pulses outputted from the capstan motor frequency generator during one rotation of the reel; And a third step of discriminating the type of video tape by inputting the number of pulses detected in the second step into the neural network algorithm.
