Abstract
(EN) Disclosed is a video encoding method using transformation units of a variable tree structure, comprising: transforming a current region on the basis of the transformation units of a variable tree structure, which is generated on the basis of the maximum division level of transformation units among transformation units divided hierarchically from an elementary transformation unit with respect to the current region, in order to encode the current region of a video; and transmitting transformation unit layer structure information, which includes information on the encoding data and encoding mode of the current region, and information on the maximum size of transformation units for the video and information on minimum size thereof.
(FR) L'invention porte sur un procédé de codage vidéo utilisant des unités de transformation d'une structure arborescente variable, lequel procédé comprend : la transformation d'une région courante sur la base des unités de transformation d'une structure arborescente variable, qui est générée sur la base du niveau de division maximal d'unités de transformation parmi des unités de transformation divisées hiérarchiquement à partir d'une unité de transformation élémentaire par rapport à la région courante, de façon à coder la région courante d'une vidéo ; et la transmission d'informations de structure de couche d'unité de transformation, qui comprennent des informations sur les données de codage et le mode de codage de la région courante, et des informations sur la taille maximale des unités de transformation pour la vidéo et des informations sur leur taille minimale.
