Abstract

Un método para codificar datos de video incluye recibir una o más capas de información de video; cada capa puede incluir al menos una imagen; el método puede incluir procesar un indicador dentro de al menos uno de un conjunto de parámetros de video (VPS), un conjunto de parámetros de secuencia (SPS), o un conjunto de parámetros de imagen (PPS) que indique si todas las imágenes de capa de referencia directa asociadas con al menos uno del conjunto de parámetros de video (VPS), el conjunto de parámetros de secuencia (SPS), o el conjunto de parámetros de imagen (PPS) son agregadas a un conjunto de imágenes de referencia inter-capa; con base en el indicador, el método además puede incluir, abstenerse de señalizar en forma adicional información de imágenes de referencia inter15 capa en alguna porción de video asociada con al menos uno del conjunto de parámetros de video (VPS), el conjunto de parámetros de secuencia (SPS), o el conjunto de parámetros de imagen (PPS); de manera alternativa, con base en el indicador, el método además puede incluir, agregar al conjunto de imágenes de referencia inter-capa todas las imágenes de capa de referencia directa para cualquier porción de video asociada con al menos uno del conjunto de parámetros de video (VPS), el conjunto de parámetros de secuencia (SPS), o el conjunto de parámetros de imagen PPS).
