Abstract

"MéTODO DE CONTROLE DE ACESSO EM TELEVISãO DIGITAL POR ASSINATURA". A invenção se refere a um método de controle de acesso, em televisão digital, por assinatura, a informações contidas em um sinal recebido por uma estação de recepção por assinatura (21), compreendendo etapas de emissão de primeiras mensagens de controle de alocação de direitos (ECM), permitindo propor aos assinantes um modo de funcionamento pay-per-view, e de segundas mensagens de gestão de alocação de direitos (EMM) para um dispositivo usuário (26) de geração no dispositivo usuário (26) de um sinal de autorização de acesso (CW), no qual se emitem primeiras mensagens de controle de alocação de direitos, tendo um conteúdo de perfil parametrizável, permitindo autorizar pelo menos um serviço ou um programa durante uma certa janela de tempo, em função do perfil de um determinado assinante, de maneira a resultar uma certa interatividade entre o conteúdo dessas primeiras mensagens e o conteúdo do dispositivo usuário em termos de assinatura para o assinante.
