Abstract
Un dispositivo de computación genera un archivo que comprende una caja de pista que contiene metadatos de una pista en el archivo. Unos datos de medios para la pista comprenden una secuencia de muestras, cada una de las muestras es una unidad de acceso de video de datos de video de múltiples capas. Como parte de la generación del archivo, el dispositivo de computación genera, en el archivo, una caja de información de submuestra que contiene indicadores que especifican un tipo de información de submuestra dado en la caja de información de submuestra. Cuando los indicadores tienen un valor en particular, una submuestra correspondiente a la caja de información de submuestra contiene exactamente una imagen codificada y cero o más unidades de capa de abstracción de red (NAL) que no son de capa de codificación de video (VCL) asociadas con la imagen codificada.
