Abstract
"PROCESSO PARA OPERAR UM SISTEMA DE ACESSO CONDICIONAL PARA APLICAçõES DE RADIOTRANSMISSãO". Em um processo para operar um sistema de acesso condicional para aplicações de radiotransmissão, sistema de acesso condicional esse que compreende diversos assinantes, cada assinante tem um terminal que inclui um módulo de acesso condicional (11) e um dispositivo seguro (12) para armazenar habilitações, cada habilitação indica um serviço ao qual o assinante que recebe a habilitação tem direito de assistir, mensagens de gerenciamento de habilitações (EMM's) são transmitidas a um dispositivo seguro ou a um grupo de dispositivos seguros. Cada uma dessas EMM's fornece uma habilitação e uma data de vencimento correspondente, sendo que as habilitações são renovadas periodicamente, de acordo com suas datas de vencimento, pela transmissão de EMM's atualizando as datas de vencimento. Além disso, um conjunto de mensagens de gerenciamento de habilitações de prorrogação (EMM's de prorrogação) é transmitido a todos os dispositivos seguros, cada mensagem indica que todas as habilitações com uma data de vencimento dentro de um primeiro período predeterminado são prorrogadas por um segundo período predeterminado, sendo que EMM's atualizando as datas de vencimento são transmitidas depois das EMM's de prorrogação.
