Setting the V Filter Cutoff
The
V Filter Cutoff
sets the vertical cutoff for the Scaler. This control manages the amount of aliasing
that the vertical scaler allows to pass from its input to output when performing scaling and aspect ratio
conversion.

vFilterCutoff
Auto, 0 to 64
This range for this control is 1 to 64. Level 1 performs the most band
limiting and results in a soft image. Level 64 performs the least band
limiting and results in a sharper image. The Auto setting automatically
selects the optimal filter based on input and output video formats.

Setting the H Filter Cutoff
The
H Filter Cutoff
sets the horizontal cutoff for the scaler. This control manages the amount of
aliasing that the horizontal scaler allows to pass from its input to output when performing scaling and
aspect ratio conversion.

Setting the Timing for the H Phase Offset
With the
H Phase Offset
control, the user can set the horizontal timing of the output video with respect
to the reference input. Setting this control to
0
keeps the output video line aligned with the reference.
For normal operation, the
H Phase
control for each converter should be set to
0
. Increasing this
value will delay the output video in one-sample increments. In order to advance the horizontal timing
of the output video with respect to the reference, set the control to the maximum number of samples
per line for the output video standard minus the number of samples that you wish to advance the
output video.
