illustrates this feature, and shows that both types of predictions differ for the two
estimators (Sa and Ta of the first estimator, Sb and Tb for the second). Both estimators
further test one candidate that is found as the sum of their spatial prediction vector and
an update vector. The last candidate is the null vector.
The left branch contains only a special null block matcher. The best matching null vector
from either of the two branches is assigned to the current block.
The overall best vector is finally selected and used for scan rate conversion.
Different penalty mechanism exist to optimize the behaviour of the both branches of the
motion estimation block.

The I²C Bus parameters below are used for optimization purposes of the motion
estimation block and should not be changed by the customer.
