Abstract

Lorsqu'une prédiction vise des champs de parités différentes, l'efficacité prédicative d'un vecteur de chrominance est améliorée par commutation adaptative de la production d'un vecteur de mouvement de chrominance qui dépend d'une parité du champ de codage ou de décodage (haut ou bas) et d'une parité du champ de référence (haut ou bas). L'efficacité du codage est par conséquent améliorée.
