PAL Comb Filter Settings
Used for PAL B/G/H/I/D, PAL M, PAL Combinational N,
PAL 60, and NTSC 4.43 CVBS inputs.
PSFSEL [1:0], Split Filter Selection PAL, Address 0x19 [1:0]
PFSEL [1:0] selects how much of the overall signal bandwidth is
fed to the combs. A wide bandwidth split filter eliminates dot
crawl, but shows imperfections on diagonal lines. The opposite
is true for a narrow bandwidth split filter.

Description
Do not use.
PAL chroma comb adapts five lines (three taps)
to three lines (two taps); cancels cross luma only.
PAL chroma comb adapts five lines (five taps) to
three lines (three taps); cancels cross luma and
hue error less well.
PAL chroma comb adapts five lines (five taps) to
four lines (four taps); cancels cross luma and hue
error well.
