Abstract

"MéTODO DE PROCESSAMENTO DE DADOS DE VìDEO CRIPTOGRAFADOS PARA GERAçãO DE DADOS DE PROGRAMA DECRIPTOGRAFADOS". Um decodificador (25) exclui um código ou chave de criptografia dos dados de saída do programa decripotografados ou não criptografados. Os dados representativos do programa decriptografados (33, 50) de um fluxo de dados de entrada contendo os dados criptografados do programa e um código de criptografia associado. Os dados criptografados do programa são decriptografados (130, 33, 50) usando o código de criptografia para fornecer os dados do programa decriptografados. Um fluxo de dados de saída é formado contendo os dados de programa decriptografados, mas excluindo o código de criptografia. O código de criptografia pode ser excluído pela substituíção (110, 55, 60, 115) dos dados de código sem criptografia pelo código de criptografia. O fluxo de dados de saída pode também conter dados auxiliares formados (115) para suportar a decodificação dos dados do programa decriptografados.
