Abstract

Un método para decodificar datos de video que comprende la división de una memoria intermedia de imágenes decodificadas (DPB) en una pluralidad de sub-DPBs, recibir al menos una indicación de un tamaño de sub-DPB para la pluralidad de subDPB para uno o más puntos de operación de un proceso de codificación de video multi-capa, y asignar espacio de memoria para la pluralidad de sub-DPBs con base en al menos una indicación.
