Adaptive comb mode
Disable luma comb
Fixed luma comb (top lines of line memory)
Fixed luma comb (all lines of line memory)
Fixed luma comb (bottom lines of line memory)
Configuration
Adaptive 3-line (3 taps) luma comb
Use low-pass/notch filter; see the 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 NTSC-443 CVBS inputs.
PSFSEL[1:0] Split Filter Selection PAL,
Address 0x19 [1:0]
PSFSEL[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.

CTAPSP[1:0]
Description
00
Do not use.
01
PAL chroma comb adapts 5 lines (3 taps) to
3 lines (2 taps); cancels cross luma only.
10
PAL chroma comb adapts 5 lines (5 taps) to
3 lines (3 taps); cancels cross luma and hue error
less well.
11 (default)
PAL chroma comb adapts 5 lines (5 taps) to 4 lines
(4 taps); cancels cross luma and hue error well.

CCMP[2:0] Chroma Comb Mode PAL, Address 0x39 [5:3]
See Table 56.
YCMP[2:0] Luma Comb Mode PAL, Address 0x39 [2:0]
See Table 57.
Vertical Blank Control
Each vertical blank control register has the same meaning for
the following bits:
00—Early by 1 line.
10—Delay by 1 line.
11—Delay by 2 lines.
01 (default) is described under each register.
NVBIOLCM[1:0] NTSC VBI Odd Field Luma Comb Mode,
Address 0xEB [7:6]
These bits control the first combed line after VBI on NTSC odd
field (luma comb).
01 (default)—SMPTE170-compliant, blank lines 1–20, 264–282,
comb half lines.
NVBIELCM[1:0] NTSC VBI Even Field Luma Comb Mode,
Address 0xEB [5:4]
These bits control the first combed line after VBI on NTSC
even field (luma comb).
01 (default)—SMPTE170-compliant, blank lines 1–20, 264–282,
comb half lines.
