Abstract

L'invention porte sur l'appareil (16) de commande d'un codeur vidéo (14) pouvant coder une unité de codage vidéo en suivant une parmi plusieurs stratégies de codage imposant respectivement différentes charges de calcul. Ledit appareil comporte un contrôleur (24) produisant des instructions de commande en fonction d'une valeur cible correspondant à la charge de calcul attribuée à un élément de traitement de signaux lors du traitement de l'unité de codage vidéo. Les instructions de commande de l'appareil transmises au codeur sélectionnent l'une des stratégies de codage et le codeur code l'unité de codage vidéo en fonction de la stratégie de codage sélectionnée.
