Multistandard video decoder with adaptive comb filter
[1]
Resulting FIR function.
8.4.2.2
Horizontal fine scaling (variable phase delay filter; subaddresses A8h to AFh and
D8h to DFh)
The horizontal fine scaling (VPD) should operate at scaling ratios between
1
2
and 2
(0.8 and 1.6), but can also be used for direct scaling in the range from
1
7.999
to
(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.
