ABSTRACT:
A hardware system is programmed with a noise tolerant vertical blanking interval (VBI) scan line run-in clock recovery function that determines the phase adjustment for reading sampling data, using only phase error observations that fall within a heavily populated phase error super-subrange, and excluding the remaining phase error observations from the determination, thereby improving the precision of the determination, and reducing unnecessary rejections of VBI scan lines.
