Remark
Saturation
Positive range 0x0000 00 → 0x3F (brightest),
Negative range 0x40 (darkest) → 0xFF
If comp filter bypass
If comp filter selection
Select filter response as part of LTI
(0:filter response 0, 1:filter response 1)
Bigger value:less obvious sharpening of luma transients,
0:max transient improvement
CTI level
Select filter response as part of CTI
(0:filter response 0, 1:filter response 1)
CTI level
Vs slice level 00 → lowest, 11 highest
Hs slice level 00 → lowest, 11 highest
Synctip noise readback
1 → auto speed up/down hs pll based on input quality, 0 → don't
Hsync pll parameter
Hsync pll parameter
Larger values give narrower bandwidth and more noise reduction
but also more motion blur DNR noise bandwidth
Larger values allow more temporal comb for noisy RF signals but
may also introduce motion error
Larger values decrease 3D comb motion detection sensitivity to
chroma motion and noise
Larger values increase 3D comb motion detection sensitivity to
chroma motion and noise
Larger values decrease 3D comb motion detection sensitivity to
luma motion and noise
Larger values increase 3D comb motion detection sensitivity to
luma motion and noise
