Abstract

Un aparato de acuerdo con algunos aspectos incluye una memoria y un procesador configurados para: en respuesta a determinar que una imagen de punto de acceso intra aleatorio (IRAP) de la capa de referencia comienza una nueva secuencia de video codificada (CVS) en la AU actual: determinar si la imagen IRAP de capa de referencia activa un nuevo conjunto de parámetros de video (VPS) o define un límite de predicción en la AU actual; en respuesta a determinar que la imagen IRAP de capa de referencia activa un nuevo VPS o define un límite de predicción en la AU actual, remover imágenes en la memoria tampón de imágenes decodificadas (DPB) asociada con cada una de una pluralidad de capas; y en respuesta a determinar que la imagen IRAP de capa de referencia no activa un nuevo VPS y no define un límite de predicción en la AU actual, remover únicamente imágenes en la DPB asociada con la capa de referencia.
