Title
(EN) INTER-PREDICTION CONCEPT USING TILE-INDEPENDENCY CONSTRAINTS
(FR) CONCEPT D'INTER-PRÉDICTION FAISANT APPEL À DES CONTRAINTES D'INDÉPENDANCE DE PAVÉS
Abstract
(EN)
Different concepts for improving video coding efficiency are described, many of them allow for video coding in a manner realizing tile-independent coding with reducing, however, the coding efficiency losses otherwise associated with the tile-dependency disruptions, with nevertheless merely marginally, if all, modifying the codec behavior alongside the tile boundaries.
(FR)
L'invention concerne différents concepts permettant d'améliorer l'efficacité de codage vidéo, un grand nombre d'entre eux permettant un codage vidéo d'une manière qui fournit un codage indépendant de pavés avec cependant une réduction des pertes d'efficacité de codage autrement associées aux perturbations de dépendance de pavés, avec une modification au demeurant marginale, si ce n'est totale, du comportement de codec parallèlement aux limites de pavés.
