Abstract

Un método de decodificación de imágenes incluye: obtener, a partir de un conjunto de parámetros de secuencia de un flujo de bits, la información que indica una pluralidad de primeras listas de imágenes de referencia para una secuencia de imágenes que incluye una imagen actual; obtener, a partir de un encabezado de grupo del flujo de bits, un indicador para un grupo de bloques actual que incluye un bloque actual en la imagen actual; obtener una segunda lista de imágenes de referencia basada en una primera lista de imágenes de referencia indicada por el indicador; y decodificar por predicción de un bloque inferior del bloque actual basándose en una imagen de referencia incluida en la segunda lista de imágenes de referencia.
