Abstract

Un sistema de distribucion multimedia. El sistema de distribucion incluye una unidad transmisora que distribuye contenido desde un proveedor de contenido a una o más unidades suscriptoras inalámbricas. La unidad transmisora incluye un decodificador configurado para determinar si una pluralidad de paquetes entrantes incluyen uno o mas paquetes borrados, un transmisor configurado para transmitir los paquetes a una unidad receptora, y un generador de codigo de deteccion de error configurado para generar un codigo de deteccion de error para cada uno de los paquetes transmitidos a la unidad receptora, estando el codigo de deteccion de error modificado para cada uno de los paquetes borrados de manera tal que la unidad receptora podrá identificar los paquetes borrados.
