Abstract

"SISTEMA E MéTODO DE TRANSMISSãO SEGURA DE DADOS." A presente invenção se refere a um sistema e a um método de transmissão e armazenamento de dados de áudio/vídeo na forma criptografada entre um centro de distribuição e pelo menos um módulo de exploração. Em lugar de transmitir a informação, permitindo a descriptografação em paralelo aos referidos dados, essa informação é reagrupada em um arquivo de dados de descriptografação, compreendendo igualmente os dados que definem as condições de acesso aos referidos dados de áudio/ vídeo. Esse arquivo é armazenado independentemente dos referidos dados e pode ser usado para um uso imediato ou prorrogado.
