Abstract

Se describe un método para unir el uso de un receptor de datos digitales de servicio de audio/vídeo a una red sobre la cual al menos un proveedor de servicios difunde las corrientes de servicios de audio/vídeo digitales, controladas en acceso y gratis, el método está caracterizado por los pasos de: la recepción por parte del receptor, de una señal periódica transmitida por un servidor del sistema de acceso condicional vía la red, la señal periódica es procesada por un software de tiempo de corrida incrustado en el receptor para verificar la legitimidad de la red, la visualización de los servicios disponibles en la red únicamente si el software de tiempo de corrida reconoce la señal periódica como indicadora de legitimidad de la red, la verificación de la operabilidad del software de tiempo de corrida y si es necesario, la toma de acciones para poner en vigor la limitación de uso del receptor sobre la red verificada como legítima. La invención describe además un receptor unido a una red específica configurada para realizar el método.
