Claims

[Scope of utility model registration request]

A circuit that identifies the difference between the reference color frame signal and the reproduced color frame signal and generates a signal indicating a match state, and a reference synchronization signal and a reproduction signal for the capstan motor that runs the tape on which the color video signal is recorded. A color video signal reproducing device comprising a circuit that applies phase servo based on a phase error of a control signal, and a circuit that superimposes a signal indicating the matching state on this phase error.
