Abstract
A set of spatial motion information predictors to be encoded is generated from among a predetermined number of spatial motion information predictors, using at least one condition to determine that a spatial motion information predictor is not includable in the set. At least one condition is a condition to exclude from the generated set of spatial motion information predictors a spatial motion information predictor that is a duplicate of another spatial motion information predictor. A temporal motion information predictor is not subjected to the duplicate exclusion condition used for the spatial motion information predictors and may be a duplicate of a spatial motion information predictor in the generated set. A motion information predictor is selected from among (i) the generated set of motion information predictors, (ii) the temporal motion information predictor, and (iii) a zero motion information predictor as a replacement for a non-includable spatial motion information predictor.
