Abstract

"MéTODO PARA CONTROLAR O DESAMONTOAMENTO DE UMA PLURALIDADE DE CORRENTES DE TRANSPORTE DE PROGRAMA, SISTEMA RECEPTOR E DISPOSITIVO DE SEGURANçA PORTáTIL". A presente invenção refere-se a um método para controlar o desamontoamento de uma pluralidade de correntes de transporte de programa recebidos por um sistema receptor, cujo método compreende receber uma seq³ência de mensagens em um subsistema de acesso condicional (9,10) compreendido no dito sistema receptor, cada mensagem sendo associada a uma de uma série de correntes de transporte de programa amontoadas e representando uma solicitação para retornar às informações, permitindo que a corrente de transporte amontoada seja desamontoada por pelo menos um módulo de desamontoador (12) no sistema receptor, determinando se as mensagens recebidas dentro de um certo intervalo são associadas a várias correntes de transporte de programa amontoados diferentes e negando pelo menos uma das solicitações representadas pelas mensagens recebidas em um certo intervalo, se o número de correntes de transporte de programas amontoadas diferentes com as quais as mensagens são associadas excede um número predeterminado.
