Abstract

Un receptor de contenidos de audio/video que está configurado para recibir el contenido de medios desde una fuente de contenidos por un camino de datos de difusión, el contenido de los medios de comunicación estando dispuestos como una pluralidad de canales de medios que comprende un módulo anfitrión que tiene un sintonizador configurado para asignar índices de canales lógicos a los canales de los medios de comunicación para permitir la selección, en el módulo anfitrión, de uno o más de los canales de medios para la reproducción mediante la selección del índice de canal lógico correspondiente, el módulo anfitrión almacena datos de asociación que asocian los índices de canal de los canales lógicos con los canales de medios recibidos; y un módulo de acceso condicional removible (CAM), el CAM tiene una unidad de control de acceso para la decodificación de contenido de difusión codificada de acceso controlado, estando dispuesto el módulo anfitrión y el CAM removible para proporcionar un enlace de comunicación encriptado para contenidos de radiodifusión codificados de acceso controlado entre el CAM decodificado y el módulo anfitrión; en donde: el módulo anfitrión está configurado para adquirir datos de la asociación de canal a través de la ruta de datos de radiodifusión; el CAM está configurado para proporcionar más datos de la asociación de canal en el módulo anfitrión; el módulo anfitrión comprende un detector configurado para detectar un conflicto de índice de canal lógico entre los datos de la asociación de canal adquiridos por el anfitrión de la ruta de datos de radiodifusión y los datos de la asociación de canal proporcionadas por el CAM y, en el caso de un conflicto, para detectar uno o índices de canales lógicos más utilizados; y el CAM está configurado para seleccionar uno de los índices de los canales lógicos utilizados para el uso de un canal de comunicación para los que el índice de canal lógico se define en los conflictos de datos de asociación de canales del CAM con un índice de canal lógico definido en datos de asociación del canales anfitrión.
