Description
Vertical auxiliary window start
The line cosited with the reference edge REVS is numbered 0.
Horizontal auxiliary window end
pixels from XWS up to and including XWE are processed
Vertical auxiliary window end
lines from YWS up to and including YWE are processed
Phase mode
0: 64 phases
1: 32 phases
2: 16 phases
3: 8 phases
4: 4 phases
5: 2 phases
6: fixed phase
7: linear phase interpolation (only valid for4 component mode)
Horizontal filter components
0: three components, 6 tap FIR each
1: four components, 3 tap FIR each (4th component unused)
In color space matrix mode this value has to remain zero
Initial zoom for 1st pixel in line (unsigned, LSB = 2
2 0000 (hex): downscale 50%
1 0000 (hex): no scaling = 2
0 8000 (hex): zoom 2 x (transposed: downscale 50%)
Quantization shift control
used to change quantization before being multiplied with
HSP_MULTIPLY.
100 (bin): divide by 16
101 (bin): divide by 8
110 (bin): divide by 4
111 (bin): divide by 2
000 (bin): multiply by 1
001 (bin): multiply by 2
010 (bin): multiply by 4
011 (bin): multiply by 8
Warning: A value range overflow caused by an improper
quantization shift can not be compensated later by multiplying with a
HSP_MULTIPLY value below 0.5!
