Abstract: PROBLEM TO BE SOLVED: To provide a stable H signal to jitter by allowing a transmitter side to send a color subcarrier with a frequency in a relation of an integer multiple of a frequency of a horizontal synchronizing signal and allowing a receiver side to apply frequency division to a frequency of a color subcarrier or a multiple of n of the color subcarrier to generate an H pulse. SOLUTION: A transmitter side uses a frequency divider circuit 26 to apply frequency division to a frequency of a color subcarrier or a multiple of (n) of that of the color subcarrier required for balanced modulation, uses a phase comparator 10 to compare the frequency with a frequency of horizontal synchronizing signal, the phase error is fed back to a VCO 11 so as to keep a relation between the frequency of the color subcarrier and an integer multiple of the frequency of the horizontal synchronizing signal. On the other hand, a receiver section 23 uses an APC circuit 18 to generate a frequency of the color subcarrier or a multiple of (n) of the frequency of the color subcarrier in phase locking with a phase of a color burst signal required for color signal demodulation.  Furthermore, a frequency divider/horizontal synchronizing pulse generating circuit 24 frequency-divides the frequency of the color subcarrier or a multiple of (n) of the frequency of the color subcarrier to be generated to generate a horizontal synchronizing pulse. Thus, a stable horizontal synchronizing signal to jitter is obtained.
