Abstract

"APARELHO DE TRANSMISSãO DE SINAL E UM MéTODO DE TRANSMISSãO DE SINAL". Um aparelho de transmissão de sinal é provido para transmitir uma pluralidade de informações de áudio codificadas, as quais são codificadas pelo mesmo método de codificação, através de uma interface digital para um aparelho de recepção de sinal, onde cada uma das informações codificadas de áudio possui uma freq³ência de amostragem de F ou 1/2 x F. O aparelho compreende uma seção de geração de dados para, com base nos dados de um quadro obtidos dividindo-se as informações codificadas de áudio em quadros, gerar pelo menos um bloco; e uma seção de saída de dados para produzir/enviar o referido pelo menos um bloco gerado pela seção de geração de dados para a interface digital. Cada um dos pelo menos um bloco inclui uma porção de corpo e uma porção dianteira que armazena informações de gerenciamento para gerenciar dados armazenados na porção de corpo.
