98 / 179 page  SDA9410 Preliminary Data Sheet Motion estimation 98 Micronas 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.
