Abstract

"MéTODO DE TRASMISSãO DE DADOS COMPACTADOS PARA UM SISTEMA DE RADIOFUSãO DE áUDIO DIGITAL, TRANSMISSOR PARA UM SISTEMA DE RADIOFUSãO DE áUDIO DIGITAL, E, FORMATO DE QUADRO DE MODEM DE COMPRIMENTO FIXO PARA TRANSMITIR INFORMAçãO DE RADIOFUSãO DE áUDIO DIGITAL". Um método de transmissão de dados compactados para um sistema de radiofusão de áudio digital compreende as etapas de produção de informação digital que representa um sinal de áudio; estimar o número de bits a serem alocados na informação digital em um quadro de modem; codificar a informação digital dentro do número estimado de bits para produzir dados codificados; remover os bits selecionados dos dados codificados; adicionar bits correspondentes às mensagens digitais na informação codificada para formar um quadro de modem composto; formatar os bits de quadro de modem composto para produzir os bits de quadro de modem composto formatados; e transmitir os bits de quadro de modem composto formatados. A invenção também engloba os transmissores que realizam o método.
