Abstract

Patente de Invenção: <B>''MéTODO PARA EMBUTIR SINAIS DE áUDIO DIGITAL COMPACTADO EM UM SINAL DE VìDEO UTILIZANDO BANDAS DE PROTEçãO''<D>. Um processador de sinal de áudio forma intervalos ou bandas de proteção em seq³ências de blocos transportando informação de áudio codificada e alinha em tempo as bandas de proteção com a informação de vídeo. As bandas de proteção são formadas para permitir variações no processamento ou atrasos do circuito de modo que o direcionamento ou a troca de fluxos diferentes de informação de vídeo com informação de áudio embutida não resulta em uma perda de quaisquer blocos de áudio codificados.
