1.7 Video Scaling, Cropping, and Temporal Decimation
Figure 1-13. Luma Peaking Filters with 2x Oversampling Filter and Luma Notch
may select two, three, four, or five taps. The number of taps must be chosen in
conjunction with the horizontal scale factor to ensure that the needed data can fit
in the internal FIFO (see the VFILT bits in the VTC register for limitations). As
the scaling ratio is increased, the number of taps available for vertical scaling is
increased. In addition to low-pass filtering, vertical interpolation is also employed
to minimize artifacts when scaling to non-integer scaling ratios. The Bt827B
employs line dropping for vertical scaling.
The number of taps in the vertical filter is set by the VTC register. The user
