X turns EDDI on and off (off or on)
coefficient for interpolated lines. Above this threshold, the differences
corresponding to the two neighbouring lines are used as clipping
parameters, below this threshold, the interpolated line difference is
used as clipping level. This parameter can be used to optimize the
de-interlacing quality in slowly moving edges; it is not likely to have
effect if PlfLim is high.
select adaptive recursive or order statistic output (order statistic or
adaptive)
Scaling factor to control the strength of the filtering for the interpolated
lines. A value 0 means no scaling (normal filtering), while 3 means
scaling by factor 8 (very strong filtering). This parameter can be used
to adjust the de-interlacing to varying level of noise in the input picture;
use higher scaling for higher noise.
disable all recursion in calculating pixels for frame memory (recursive
or non recursive)
de-interlacing. Values 0 to 14 (on a scale of 16) indicate attenuation.
A value of 15 indicates no attenuation.
sensitivity scaling factor in transition from average to median in initial
de-interlacing
chooses between majority selection and median/average mix for initial
de-interlacing (majority or mix); when KplFad = 0, FadDiv and
DeiOfs are don’t cares
activates split screen demonstration mode for EDDI (off or on)
Factor to specify the size of the additional compensation area left and
right of the ‘real’ edge. A high factor (e.g. 1) can increase the
compensation in regions far away from the true edge (1,
