Abstract

Patente de Invenção: "MéTODO E APARELHO PARA TRANSMISSãO DE SINAIS DE áUDIO CODIFICADOS ATRAVéS DE UM CANAL DE TRANSMISSãO COM COMPRIMENTO DE BANDA LIMITADO". Um sistema transmissor de áudio digital capaz de transmitir fala de banda extensa de alta qualidade sobre um canal de transmissão com um comprimento de banda limitado, tal como uma linha de telefone tradicional. O sistema transmissor de áudio digital inclui um codificador para codificar um sinal de áudio de entrada para um sinal digital possuindo uma taxa de transmissão para linhas de telefone tradicionais e um decodificador para decodificar o sinal digital para fornecer um sinal de áudio de saída com um comprimento de banda de áudio de fala de banda extensa. Um codificador e um decodificador podem ser fornecidos em um único dispositivo para permitir uma comunicação em duas direções entre múltiplos dispositivos.
