Title: Horizontal synchronization reproduction circuit
Inventor: NAKAO ATSUSHI
IPC: H04N5/06
Filed: 1992-02-10
Abstract: PURPOSE:To improve a characteristic against noise and responsiveness by controlling an oscillation frequency by means of the output of an integrating circuit operated at a period except for the period and the phase comparison result of a horizontal synchronous pulse when the phase of the horizontal synchronous pulse coincides with that of the horizontal synchronizing signal. CONSTITUTION:A synchronization separation circuit 2 separates the horizontal synchronizing signal (HS) from a composite video signal, and VCO 5 outputs the oscillation frequency for horizontal synchronization reproduction. A logic circuit 6 generates the horizontal synchronous pulse (HP) and the pulse equivalent to the HS period based on the oscillation frequency of the circuit 5, and a discrimination circuit 7 discriminates the coincidence/non-coincidence of HP and HS. The integrating circuit 3 integrates HS and a control means 9 operates the circuit 3 in the period except for the period of the pulse equivalent to the HS period when the phase of HP coincides with that of HS. A phase detection circuit 4 controls the oscillation frequency of the circuit 5 from the comparison result of the output of the circuit 3 and the phase of HP. Thus, the circuit is stabilized as against the disturbance of noise and responsiveness is improved.
