Abstract

CODIFICAÇÃO E DECODIFICAÇÃO DE SINAL COMPATÍVEL COM VERSÕES ANTERIORES HÍBRIDO. Trata-se de hardware de processador de computador que analisa um fluxo de dados para as primeiras porções de dados codificados e as segundas porções de dados codificados; implanta um primeiro decodificador para decodificar as primeiras porções de dados codificados para uma primeira representação de um sinal; implanta um segundo decodificador para decodificar as segundas porções de dados codificados para os dados de reconstrução, sendo que os dados de reconstrução especificam como modificar a primeira representação do sinal; e aplica os dados de reconstrução à primeira representação do sinal para produzir uma segunda representação do sinal.
