Abstract

PURPOSE: To detect a desired picture-recorded part rapidly by finding the desired picture-recorded part by deciding the number of sweep signals by reproducing sweep signals of an audio frequency or higher recorded on an audio track.
CONSTITUTION: Sweep signals of an audio frequency or higher varying in the number of signals through gate unit 3 brought under on-off control corresponding to pulses of sweep signal generator 1 and pulse generator 2 are mixed with an audio signal by mixer 5, whose output is recorded on the audio track of a video cassette. This record is reproduced in fast-forwarding mode and passed through frequency separator 9, BPF11, etc., to separate and detect only reproduced sweep signals, which is counted by pulse counter 14. Then, the count value of counter 14 is compared to the number of pulses set by pulse assigning unit 15 corresponding to the desired picture-recorded part by comparator 16, the coincidence signal of which controls switch 17 changed over from fast forwarding over to normal forwarding, so that the desired picture-recorded part can rapidly be detected and selected without monitoring a reproduced picture.
