Abstract

MéTODO PARA TRANSMITIR MúLTIPLOS FLUXOS EM REDES DE BROADCAST SEM FIO Conseqüentemente, são providos método e equipamento para converter conteúdo recebido em um primeiro fluxo e em um segundo fluxo, para transmitir o primeiro fluxo utilizando um primeiro tom e para transmitir o segundo fluxo utilizando um esquema ortogonal. Um esquema de disposição em camadas é utilizado para transmitir o fluxo básico cobrindo uma área e um fluxo otimizado é utilizado para cobrir uma área grande utilizando esquema ortogonal.
