Title
(EN) PICTURE RESOLUTION DEPENDENT CONFIGURATIONS FOR VIDEO CODING
(FR) CONFIGURATIONS DÉPENDANT D'UNE RÉSOLUTION D'IMAGE POUR UN CODAGE VIDÉO
Abstract
(EN)
A video coding method is performed at a computing device having one or more processors and memory storing a plurality of programs to be executed by the one or more processors. The method includes selecting a first temporal motion vector prediction compression scheme in response to any of a first picture resolution, a first profile, or a first level; and selecting a second temporal motion vector prediction compression scheme in response to any of a second picture resolution, a second profile, or a second level.
(FR)
Un procédé de codage vidéo est réalisé au niveau d'un dispositif informatique ayant un ou plusieurs processeurs et une mémoire mémorisant une pluralité de programmes devant être exécutés par le ou les processeurs. Le procédé consiste à sélectionner un premier schéma de compression de prédiction de vecteur de mouvement temporel en réponse à un élément quelconque parmi une première résolution d'image, un premier profil ou un premier niveau ; et à sélectionner un second schéma de compression de prédiction de vecteur de mouvement temporel en réponse à un élément quelconque parmi une seconde résolution d'image, un second profil ou un second niveau.
