TavLow

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 (1or2).

TavUpp

X X

see above; TavUpp is the upper threshold (0, 4, 8 or 16)

MotShiFac

XXXXXX 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).
