Slicing Level Value
The horizontal PLL requires a slicing level . This bitfield indicates the slicing level as a fraction between the
blanking and the sync tip level. The blanking level is used as the reference level for the clamp mechanism.
(See also bit BLANKMODE[1:0] in register
video signal by the synchronization mechanism.
0000: Slicing Level = Blank Level
1111: Slicing Level = (Blank – sync tip )/16 + sync tip
Reserved. Must be set to 0000.
Green Enhancement Mode Enable
The Green Enhancement mechanism is applied to the CVBS flow only and is only valid for the NTSC M and
the NTSC 4.43 standards. The green tone axis has been defined as flesh tone axis + 90 degrees in the
vectorscope representation (i.e. 213 or 207 degrees). Green enhancement is only performed during the
active line. Green enhancement operates through saturation increase. Saturation increase factor k is a
linear function of the color phase distance to green axis.
k = 1 for color phase - green axis = ± 22.5 degrees (minimum value)
k = 1.2 for color phase = green axis (maximum value)
(k always 1 when color phase not at 22.5 degrees of green axis)
0: Green Enhancement mode is disabled.
1: Green Enhancement mode is enabled.
Tint Angle
The Tint Angle is applied to the Cr and Cb values of the RGB data flow after the RGB to YCrCb conversion.
The Tint Angle is coded from -20° to +20° in steps of 1.33°. The bitfield is coded in 2's complement.
