Use low-pass/notch filter; see the
195H
Y-Shaping Filter section.
Fixed 2-line (2 taps) luma comb.
Fixed 3-line (3 taps) luma comb.
Fixed 2-line (2 taps) luma comb.
PAL Comb Filter Settings
Used for PAL-B/G/H/I/D, PAL-M, PAL-Combinational N, PAL-
60, and NTSC443 CVBS inputs.
PSFSEL[1:0] Split Filter Selection PAL, Address 0x19[1:0]
The PSFSEL[1:0] control selects how much of the overall signal
bandwidth is fed to the combs. A wide split filter selection
eliminates dot crawl, but shows imperfections on diagonal lines.
The opposite is true for selecting a narrow bandwidth split filter.
