Abstract
PURPOSE:To decrease a chrominance signal rising time attended with the changeover of recording/reproduction by fixing an output voltage of an APC detection circuit at the time of recording and an output voltage of an AFC detection circuit at the time of reproduction respectively to a prescribed voltage. CONSTITUTION:An output voltage of an AFC detection circuit 12 is a voltage V at the time of recording and a VCO 5 is oscillated at 320fH in this case. A fixed voltage generating circuit 15 receives an output of the AFC detection circuit 12 to output a voltage V to fix the output voltage of the APC detection circuit 11 to the voltage V via a switch S3. Thus, almost the same control voltage is applied to the VCO 5 even when the recording mode is switched to the reproduction mode. The switch S3 is changed over to the position of reproduction at the time of changeover from the reproduction to the recording and the output voltage of the AFC detection circuit 12 is fixed to the voltage V by the fixed voltage generating circuit 15.
