ABSTRACT:
A hardware system is programmed with a vertical blanking interval (VBI) scan line run-in clock recovery function, preferably noise tolerant that optimizes the starting point for recovering the leading run-in clock of a VBI scan line by maintaining at least one average starting position for VBI scan lines, and using the at least one average starting position to establish the starting point. The at least one average starting position is updated continuously with the actual locations where first rising edges in the run-in clocks of various scan lines are found.
