write; S
X If the difference between the current vector and the previous one in
the same spatial location is within a small window, then the two
vectors are averaged to improve temporal consistency. TavLow is the
lower threshold of this window (1 or 2).
X X see above; TavUpp is the upper threshold (0, 4, 8 or 16)

scaling factor to reduce all sizes of update vectors in the ensemble
with medium sized vector templates (1, ¹â„₂, ¹â„₄ or ¹â„₈)
scaling factor to reduce all sizes of update vectors in the ensemble
with large sized vector templates (1, ¹â„₂, ¹â„₄ or ¹â„₈)
X X X X X X Motion estimator shift factor, being the temporal position used in the
estimator at which the matching is done; value 32 for matching at
previous field position down to 0 for matching at current field position.
Keeping MotShiFac equal to UpShiFac in the next upconverted output
field estimates for minimum matching errors (minimum Halo’s).
MotShiFac at value 16 gives the largest natural vector range (twice as
large as with value 0 or 32). Going above the range with
MotShiFac ≠ 16 is dealt with in SAA4992H by shifting towards 16, but
for the horizontal and vertical component separately (consequence is
that vector candidates tend to rotate towards the diagonal directions).
