Abstract
Se proporcionan métodos y aparatos de codificación de video. Una serie de dos o más imágenes se codifica. La serie incluye al menos una primera imagen codificada con una primera resolución espacial, y una segunda imagen codificada dentro de una segunda resolución espacial diferente de la primera resolución espacial. La serie de dos o más imágenes se almacena en una memoria tampón de imagen decodificada con base en resoluciones espaciales correspondientes. La serie de dos o más imágenes almacenadas en la memoria tampón de imagen decodificada se utiliza como una serie de imágenes de referencia para codificar una o más imágenes sucesivas subsecuentes a la serie de dos o más imágenes. La serie de dos o más imágenes se incorpora en una lista de imagen de referencia que contiene imágenes con al menos dos resoluciones espaciales diferentes.
