ル装置。[Scope of claim for utility model registration] FG output from a frequency generator attached to the capstan motor of a video tape recorder
A counting means for counting signals and outputting the above-mentioned count value, and comparing the count value output from the above-mentioned counting means and the input set value, and when the above-mentioned count value and the set value match, the above-mentioned count value is reset and matched. a comparison means for outputting a signal; and a count value of the FG signal corresponding to the amount of rewinding of the videotape at the time of reverse playback during splice recording, is outputted to the comparison means as the set value to perform a predetermined reverse playback operation. and in response to a coincidence signal outputted from the comparison means, outputs the counted value of the FG signal corresponding to the travel distance of the videotape during playback following the reverse playback to the comparison means as the set value to obtain a predetermined value. 1. A system control device for a video tape recorder, comprising: a control means for performing a playback operation and for controlling a predetermined recording operation in response to a coincidence signal output from the comparison means.
