Abstract

Una representación codificada (60) de una imagen (10) de una corriente de video (1) se descodifica al recuperar información de descripción de memoria intermedia que identifica una descripción de memoria intermedia que define múltiples imágenes de referencia (40, 42) de la corriente de video (1) a partir de la representación codificada (60) Un identificador de imagen de una imagen de referencia (42) se determina basándose en la información de identificador de imagen recuperada de la descripción de memoria intermedia para la imagen de referencia (42) y una imagen de referencia que precede a la imagen de referencia de acuerdo con un orden de lista en la descripción de memoria intermedia. El identificador de imagen determinado se utiliza para actualizar una memoria intermedia de imágenes descodificadas (230, 350) que almacena imágenes de referencia (40, 42) que se utilizan como referencia de descodificación para la imagen (10) y/o cualquier imagen subsiguiente (50) de la corriente de video (1).
