Abstract

PURPOSE: To attain a color frame servo by decelerating or accelerating magnetic tape speed until the phase of a reproducing color frame signal is put into at least one ±field to the phase of a reference color frame signal.
CONSTITUTION: A reference color frame signal RCF is made into one input of a detecting circuit 14 and a reproducing color frame signal PCF is made into other input. At the detecting circuit 14, when a reproducing color frame signal PCF exists during approximately one ±field period of the signal RCF, a control circuit 15 is turned off, the output of an adding circuit 9 is passed to a driving circuit 7 and a usual frame servo is attained. On the other hand, when the signal exists during the period except the approximately one ±field period, the control circuit 15 is turned on, and it is switched to the action of accelerating or decelerating to neglect the output of the adding circuit 9. When the approximately one ±field period is obtained, the command is released and it is returned to a usual frame servo.
