Abstract

"RECEPçãO CONFIáVEL DE CONTEúDO BROADCAST / MULTICAST". Sistemas e métodos para sistemas e métodos para difusão de forma segura de conteúdo a uma pluralidade de usuários e facilitar distribuição de porções do conteúdo de broadcast que não foram recebidas por usuários específicos, ou foram recebidas com erros. Em uma modalidade, um sistema de comunicação sem fio é configurado para difundir conteúdo de uma fonte de conteúdo para uma pluralidade de dispositivos de usuários. A fonte de conteúdo é configurada para fornecer o conteúdo a uma estação base. A estação base divide o conteúdo em uma pluralidade de segmentos e associa identificadores seqüenciais com cada um dos segmentos. O conteúdo é então transmitido para cada um dos dispositivos de usuários. Um identificador de uma fonte de dados alternativa também é fornecido aos dispositivos de usuários. Quando uma estação móvel recebe os segmentos, examina os identificadores de segmento para identificar segmentos faltantes. Os segmentos são então recuperados da fonte de dados alternativa identificada pela estação base.
