ABSTRACT:
A tape has Y and C components of a television signal recorded in different tracks. This can lead to mistiming and hence misregistration errors. To correct this a phase error signal is generated from the horizontal sync signals in each track and used to control variable delay lines for the Y and C to correct the misregistration. Separate delay lines for the I and Q components can also be used.
