Abstract

Se facilita un método para gestionar una lista de imágenes de referencia, y un aparato que lo usa. Un método de descodificación de imagen incluye los pasos de: descodificar una imagen de imágenes de capa temporal segunda más alta en una configuración jerárquica de imágenes; y descodificar imágenes de capa temporal superior que preceden y siguen a las imágenes de capa temporal segunda más alta con respecto a un recuento de orden de imágenes (POC) en una secuencia de POC, respectivamente. Por lo tanto, las imágenes de referencia disponibles permanecen en una memoria intermedia de imagen descodificada (DPB), mejorando por ello la eficiencia de codificación de imagen.
