Hue Phase Adjust
This register sets the hue phase offset adjustment. This 8-bit number is applied as a
phase offset to the CbCr data coming out of the demodulator. This 8-bit number is a in
the range of +127 to -128. The hue adjust has as range of 30

phase adjustment. This register is in two’s complement format,
where bit 7 is the sign bit.

High Frequency
Enhancement Factor
These bits adjust the amplitude of high frequency components in the luminance video
signal. The attenuation or multiplication of the high frequency components is adjusted as
shown below:
00 = Multiply high frequency components by 1.0
01 = Multiply high frequency components by 2.0
10 = Multiply high frequency components by 4.0
11 = Zero out high frequency components.

Middle Frequency
Enhancement
Factor
These bits adjust the amplitude of middle frequency components in the luminance video
signal. The attenuation or multiplication of the middle frequency components is adjusted
as shown below:
00 = Multiply middle frequency components by 1.0
01 = Multiply middle frequency components by 2.0
10 = Multiply middle frequency components by 4.0
11 = Zero out middle frequency components.

Low Frequency
Enhancement
Factor
These bits adjust the amplitude of low frequency components in the luminance video sig-
nal. The attenuation or multiplication of the low frequency components is adjusted as
shown below:
00 = Multiply low frequency components by 1.0
01 = Multiply low frequency components by 2.0
10 = Multiply low frequency components by 4.0
11 = Zero out low frequency components.

Vertical High
Frequency
Enhancement
Factor
These bits adjust the amplitude of vertical high frequency components in the luminance
video signal. The attenuation or multiplication of the vertical high frequency components
is adjusted as shown below:
00 = Multiply vertical high frequency components by 1.0
01 = Reserved.
10 = Reserved.
11 = Zero out vertical high frequency components.
