Abstract

Se divulgan diversos métodos, aparatos y productos de programa informático para encapsulamiento y desencapsulamiento de medios. En un método de ejemplo para encapsular datos de medios, se forma un fichero contenedor que incluye al menos una unidad de metadatos en una estructura de datos de medios. Puede determinarse que un desplazamiento está relacionado con una ubicación de la estructura de datos de medios en el fichero contenedor, en donde los datos de desplazamiento están formados como una referencia a la ubicación de la estructura de datos de medios en la unidad de datos de medios. Se incluye una indicación de que los datos de desplazamiento están relacionados con la ubicación de la estructura de datos de medios. En un método de ejemplo para desencapsular datos de medios, se recibe un fichero contenedor que incluye al menos una unidad de metadatos en una estructura de datos de medios y datos de desplazamiento. Puede determinarse que los datos de desplazamiento están relacionados con una ubicación de la estructura de datos de medios en el fichero contenedor, en donde los datos de desplazamiento se usan como una referencia a la ubicación de la estructura de datos de medios para obtener la unidad de datos de medios.
