Abstract
La presente invención divulga un aparato para codificar información de video de acuerdo con ciertos aspectos, que incluye un procesador configurado para determinar un valor de una bandera asociada con una imagen actual de una capa actual a decodificar, la bandera que indica si las imágenes en un búfer de imágenes decodificadas (DPB) deben ser emitidas, en donde la imagen actual es una imagen de punto de acceso intra-aleatorio (IRAP) que inicia una nueva secuencia de video codificado (CVS) y en donde la determinación del valor de la bandera se basa en al menos uno de: (1) el formato de croma de la imagen actual y el formato de croma de la imagen precedente, (2) la profundidad de bits de las muestras de luma de la imagen actual y la profundidad de bits de las muestras de luma de la imagen precedente, o (3) la profundidad de bits de las muestras de croma de la imagen actual y la profundidad de bits de las muestras de croma de la imagen precedente.
