METHOD FOR CONTROLLING A VIDEO-TAPE APPARATUS FOR THE AUTOMATIC SPOTTING OF RECORDED VIDEO-TAPE SEGMENTS AND VIDEO-TAPE APPARATUS FOR IMPLEMENTING SUCH METHOD

摘要

A method of controlling a video tape device for the automatic search of video tape recorded segments (13, 17), in particular in case of rapid unwinding of the band, where a search value insertable and characterizing the beginning of the segment videotape (13, 17) is compared with the position of a counter (58) which has a positive or negative depending on the tape unwinding direction. In order to improve the accuracy of the mark the beginning of the video segments (13, 17) used CTL pulses used for synchronization of video heads for controlling the counter (58). At the beginning of video segments is written on the tape a modification of CTL pulses, for example in the form of a CTL pulses vacuum (25), which is read and evaluated by the CTL head (48) and serves controlling the band search progress.
