In a method of compensating errors in comb filters in a line-locked sample domain, an input video signal (CVBS) is delayed (LD1, LD2) by first and second integral numbers of lines to obtain first and second delayed signals, a phase difference is measured (PM) between at least two of the input video signal (CVBS) and the first and second delayed signals, and a phase of the input video signal (CVBS) and a phase of the second delayed signal are corrected (PC1, PC2) with respect to the first delayed signal in dependence on the phase difference. |
