Abstract

PURPOSE: To enable to simplify the circuit constitution, by forming virtual pulse signal in synchronizing with the burst signal in the color TV signal by the recording APC circuit and performing frequency conversion with the APC circuit at reproduction.
CONSTITUTION: At recording, the APC circuit 13 forms the vitrual pulse signal in synchronizing with the burst signal in the color TV. Further, at reproduction, it forms the signal u frequency-converted 19 based on the virtual burst signal and performs frequency conversion for the carrier signal converted and recorded with the signal u. Thus, the circuit constitution is made simpler by commonly using the APC circuit forming the virtual burst signal with that forming the frequency conversion signal.
