CA 2110602

In a system for identifying specific horizontal lines of video that are included in a video signal, a horizontal tine counter (100) is cleared to indicate the beginning of a vertical interval by a reset signal (VERDEL) derived from a vertical sync signal (VER). The line counter is clocked by a signal (HOR) at the horizontal sync rate that is derived from a harmonic (N-FH) of the horizontal sync signal. The relative phase shift between the reset and clock signals for the horizontal line counter is mea- sured (105, 120). The measured phase shift is used as an input to a variable phase shifter (110) to adjust the phasing between the horizontal line counter control signals and the original sync signals. The phase adjustment permits significantly decrea- sing the sensitivity of the horizontal line counter to jitter of vertical sync.
