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, determinar un número de imágenes de capa de referencia activa asociadas con al menos una imagen de una o más capas; el método además puede incluir, determinar un número de capas de referencia directa asociadas con al menos una de una o más capas; con base en el número de capas de referencia directa que iguala el número de imágenes de capa de referencia activa, el método además puede incluir abstenerse de señalizar en forma adicional información de imágenes de referencia inter-capa en cualquier porción de video asociada con 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); de manera adicional o alternativa, con base en el número de capas de referencia directa que iguala el número de imágenes de capa de referencia activa, el método 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 de un conjunto de parámetros de video (VPS), un conjunto de parámetros de secuencia (SPS), o un conjunto de parámetros de imagen (PPS).
