Skew error correction circuit for video signal reproducing apparatus.

摘要

A skew error correction and a time base error compensation device for a video signal in a television receiver or the like is diclosed. An oscillator (407) produces an oscillation output signal of a constant frequency which is phase-synchronized with horizontal synchronization information included in an input video signal, and the output signal is used as a write clock. In a vertical blanking period, the oscillation output signal or a frequency-divided signal thereof is phase-compared with an output of a reference signal generator of a predetermined frequency or a frequency-divided signal thereof, and a phase error signal is negatively fed back to voltage control means which voltage-controls the oscillation frequency of the oscillator. Thus, the oscillation frequency is stabilized without using an AFC circuit and a time base error in the input video signal is eliminated.
