Abstract

"DECODIFICADOR MULTIMìDIA E SISTEMA DE COMUNICAçãO DE DIFUSãO BIDIRECIONAL" Trata-se de um aparelho (10, 20) que decodifica dados de entrada de vídeo que são codificados em formatos de dados diferentes e são recebidos em um link de comunicação físico comum. O decodificador inclui um primeiro processador (50) para decodificar os dados representativos de imagem que são empacotados em um formato de dados compatível com a Internet e são recebidos no link de comunicação comum. O decodificador também inclui um segundo processador (75) para concorrentemente decodificar dados de difusão de vídeo que são empacotados em um formato de dados compatível com MPEG exclusivo do formato de dados de protocolo Internet e são recebidos no link de comunicação comum. O primeiro e o segundo processadores produzem respectivamente a primeira e a segunda saída de vídeo decodificadas. Além disso, a proporção de dados representativos de imagem transportados no link de comunicação comum em relação aos dados de difusão de vídeo pode ser dinamicamente variada. O decodificador também inclui um processador de exibição (55, 80) para formar uma imagem de exibição a partir das primeira e segunda saídas de vídeo decodificadas.
