Abstract

La presente invencion se refiere a sistemas y metodos para sistemas y metodos para difundir confiablemente el contenido a una pluralidad de usuarios y facilitar la distribucion de porciones del contenido de difusion que ya sea no fueron recibidas por usuarios particulares, o fueron recibidas con errores. En una modalidad, un sistema de comunicacion inalambrica es configurado para difundir el contenido de una fuente de contenido a una pluralidad de dispositivos de usuarios. El contenido de la fuente esta configurado para proporcionar el contenido a una estacion base. La estacion base reconoce el contenido en una pluralidad de segmentos y asocia los identificadores secuenciales con cada uno de los segmentos. El contenido es entonces difundido a cada uno de los dispositivos de usuarios. Un identificador de una fuente de datos alternativa tambien se proporciona a los dispositivos de usuarios. Cuando una estacion movil recibe los segmentos, examina los identificadores de segmentos para identificar los segmentos perdidos. Los segmentos son entonces recuperados de la fuente de datos alternativa identificada por la estacion base.
