Abstract

Patente de Invenção <B>"BAIXA DE APLICAçõES EM UM DECODIFICADOR DIGITAL"<D>. Um método para baixar uma aplicação executável em um decodificador (1) para um sistema de difusão digital, caracterizado pelo fato de que a aplicação é armazenada em um cartão de memória portátil introduzido em uma leitora de cartão (6, 7) no decodificador, o decodificador lendo e baixando a aplicação do cartão. Os dados podem ser, de preferência, armazenados no cartão inteligente em um formato de dados de difusão, tal como um formato MPEG, para permitir o processamento desses dados da mesma maneira que a unidade de controle (40) do decodificador processa a baixa de dados por uma transmissão difundida. A invenção se estende igualmente a um decodificador e a um cartão de memória para uso em tal método.
