Abstract

RESUMEN Un dispositivo genera, en una casilla contenedora de un archivo para el almacenamiento de contenidos de video, una casilla de SampleGroupDescription que proporciona una descripción del grupo de muestra para una agrupación de muestra. La casilla de SampleGroupDescription incluye un elemento de sintaxis de tipo de agrupación que tiene un valor particular. Además, la casilla de SampleGroupDescription incluye una o más entradas del grupo de muestra. El dispositivo genera, en la misma casilla contenedora, una pluralidad de casillas de SampleToGroup. Cada casilla de SampleToGroup respectiva de la pluralidad de casillas de SampleToGroup incluye un elemento de sintaxis de tipo de agrupación respectivo que tiene el valor particular, incluye un elemento de sintaxis de recuento de muestras respectivo que indica un número de muestras en una agrupación de muestra respectiva, e incluye un elemento de sintaxis de índice de descripción del grupo respectivo que indica un índice de una entrada en la casilla de SampleGroupDescription que describe las muestras de la agrupación de muestra respectiva. Cada muestra de la agrupación de muestra respectiva comprende una imagen respectiva de los contenidos de video.
