Abstract

Patente de Invenção: <B>"MéTODO E APARELHO PARA A REPRODUçãO DE CORRENTES DE DADOS DIGITAIS"<D>. Em correntes de transporte de DVB/MPEG, a PID especifica a atribuição dos pacotes para as diferentes correntes elementares. Para a reprodução das corrente elementares, por exemplo, por intermédio de uma "set-top box", com saída através da tela de um aparelho de televisão, os pacotes do programa desejado têm que ser selecionados da corrente de transporte por meio das PIDs, usando o demultiplexador. Isso requer, em cada caso, a avaliação da Tabela de Associação de Programas e da Tabela de Mapas de Programa e também que as PIDs das correntes elementares a serem reproduzidas sejam conhecidas do demultiplexador na "set-top box". Se a "set-top box" tiver uma interface digital por meio da qual partes da corrente de dados de transporte podem ser armazenadas e reproduzidas mais tarde ou por meio da qual uma corrente de dados de transporte arbitrária pode ser alimentada a para "set-top box", o demultiplexador deve primeiramente, ser reprogramado com as PIDs. A reprodução simplesmente pela compressão de um botão de reprodução (play) é possível de acordo com a invenção, porém, em virtude do fato de que a PID para os pacotes de pelo menos uma das correntes de dados é estabelecida em um valor predeterminado na "set-top box", os pacotes com esse valor predeterminado da PID sendo selecionados para reprodução.
