Abstract

Un método de operación de un receptor de contenido de audio/vídeo que tiene un decodificador de contenido capaz de decodificar un programa de audio/vídeo desde un flujo de datos empaquetados mediante el uso de paquetes de datos que definen la información de descifrado que comprende los pasos de: recibir contenido codificado de audio/vídeo como un flujo de datos empaquetados que comprende uno o más programas que tienen paquetes de datos identificados por los respectivos conjuntos de uno o más identificadores de paquete y que comprende programas de mapeo de datos de identificación a los respectivos conjuntos de identificadores de paquetes; seleccionar paquetes de datos desde el flujo de datos empaquetado para un programa necesario de acuerdo con el conjunto de identificadores de paquetes definidos por los datos de identificación para que el flujo en relación con el programa deseado; seleccionando además paquetes desde el flujo se datos empaquetado desde el cual se selecciona un programa que tiene identificadores de paquetes no incluidos en los datos de identificación para ese flujo de datos empaquetado; la generación de un flujo de datos empaquetado compuesto a partir de los paquetes seleccionados; generar un flujo de datos de identificación compuestos que indica identificadores de paquete de los paquetes incluidos en el flujo de datos empaquetados compuestos; y suministrar el flujo de datos empaquetado compuesto al contenido decodificador para decodificar el programa desde el flujo de datos empaquetados compuestos de acuerdo con los identificadores de paquetes en los datos de identificación de flujo compuesto.
