D8h to DFh)
The horizontal fine scaling (VPD) should operate at scaling ratios between
(0.8 and 1.6), but can also be used for direct scaling in the range from
(theoretical) zoom 3.5 (restriction due to the internal data path architecture), without
prescaler.
In combination with the prescaler a compromise between sharpness impression and alias
can be found. This is signal source and application dependent.
For the luminance channel a filter structure with 10 taps is implemented, and for the
chrominance a filter with 4 taps.
