Bit Description
Reserved.
SFL_INV. Controls the behavior of
the PAL switch bit.
Reserved.
GDECEL[15:8]. See the Comments
column.
GDECEL[7:0]. See the Comments
column.
GDECOL[15:8]. See the Comments
column.
GDECOL[7:0]. See the Comments
column.
GDECAD. Controls the manner in
which decoded Gemstar data is
inserted into the horizontal blanking
period.
Reserved.
CTI_EN. CTI enable.
CTI_AB_EN. Enables the mixing of
the transient improved chroma with
the original signal.
CTI_AB[1:0]. Controls the behavior
of the alpha-blend circuitry.
Reserved.
DNR_EN. Enable or bypass the DNR
block.
Reserved.
CTI_CTH[7:0]. Specifies how big the
amplitude step must be to be
steepened by the CTI block.
DNR_TH[7:0]. Specifies the
maximum edge that is interpreted
as noise and is therefore blanked.
