Abstract

"EQUIPAMENTO E MéTODO PARA DECODIFICAçãO DE SINAIS DE IMAGEM E áUDIO DIGITAIS. São reivindicados um equipamento e um método para a decodificação de sinais codificados representando pelo menos informações de imagem a partir de um meio de armazenamento. Um dispositivo de armazenamento (136) está configurado para receber o meio de armazenamento. Um decodificador (144) está configurado para receber os sinais codificados comprimidos criptografados provenientes do meio de armazenamento e enviar os sinais para um decriptografador (320, 324). O decriptografador está configurado para decriptografar os sinaisncomprimidos criptografados codificados e envia os sinais ao descompressor (320/324). O descompressor (320, 324) está configurado para receber os sinais codificados comprimidos provenientes do decodificador e para descomprimir os sinais comprimidos codificados para capacitar a exibição da imagem.
