Abstract

PURPOSE:To adjust the phase of chrominance subcarrier signal automatically and very easily, by connecting a video signal from a video device to a video switcher and connecting a black burst signal from an automatic phase coupler to a drive signal. CONSTITUTION:A chrominance subcarrier signal is inputted to a terminal 21 of an automatic phase coupler A from a video device 5 such as television camera, and the phase difference with the reference chrominance subcarrier from a terminal 22 is detected at a phase difference detection circuit 2. If the error voltage is within E1 and E2 (where E1>E2), the phase coupling is continuously made at the range by a + or -60 deg. phase adjuster 3. If the error voltage is greater than the E1 or less than the E2, either one of four phases in 0-270 deg. is selected with comparators 7, 8 and a counter 9 to obtain the output for a multiplexer 5 and the phase of the synchronizing signal is changed in step. The phase of the chrominance subcarrier is coincided accurately and easily without using the measuring device for such as video device of mobile type, by repeating the operation, for confirmation.
