Active when EstMode = 0; replace the spatial prediction of one
estimator (left or right) by that of the other if the match error of the
former exceeds that of the latter by more than (0, 8, 16, 32, 64, 128,
256 or 511). A higher threshold means the two estimators are very
independent.
Active when EstMode = 0; select as estimated vector the output of the
right estimator unless its match error exceeds that of the left estimator
by more than (0, 8, 16 or 32). This parameter should normally be set
to logic 0.
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).
see above; TavUpp is the upper threshold (0, 4, 8 or 16)
