SFL_INV; controls the behavior

of the PAL switch bit

SFL-compatible with newer video

encoders

The newer video

encoders are

ADV7340, ADV7341,

ADV7342, ADV7343,

ADV7344, ADV7390,

ADV7391, ADV7392,

ADV7393, ADV7171,

ADV7172, ADV7173,

ADV7174, ADV7177,

and ADV7179.

ADV7194 is an

example of an older

encoder.

SFL-compatible with older

video encoders, such as the

ADV7194.

CTI DNR

Control 1

CTI_EN; CTI enable

Disables CTI

Enables CTI

CTI_AB_EN; enables the

mixing of the transient

improved chroma with the

original signal

Disables CTI alpha blender

Enables CTI alpha blender

CTI_AB[1:0]; controls the

behavior of the alpha-blend

circuitry

Sharpest mixing between

sharpened/original chroma signal

Sharp mixing between sharpened

and original chroma signal

Smooth mixing between

sharpened/original chroma signal

Smoothest mixing between

sharpened and original chroma

signal

Reserved

Sets to default

DNR_EN; enables or bypasses

the DNR block

CTI DNR

Control 2

CTI_C_TH[7:0]; specifies how

big the amplitude step must

be to be steepened by the CTI

block

0x50

DNR Noise

Threshold 1

DNR_TH[7:0]; specifies the

maximum luma edge that is

interpreted as noise and is

therefore blanked
