Abstract

"MéTODO, SISTEMA E ENTIDADES DE REDE PARA INDICAR O MODO HIERáRQUICO PARA OS FLUXOS DE TRANSPORTE CARREGADOS EM UMA TRANSMISSãO DE BANDA LARGA DIGITAL". Método para transmissão, método para recepção, sistema, transmissor e receptor para sinalizar o mapeamento de prioridade hierárquica de um fluxo de transporte (TS) para um receptor, são descritos. Uma forma para separar a informação de sintonização entre diferentes TSs com prioridades diferentes é descrita. Em uma transmissão de banda larga hierárquica sem fio, preferivelmente baseado no DVB-T, um sinal pode carregar dois fluxos de transporte: o fluxo de prioridade baixa (LP) e o fluxo de prioridade alta (HP), e ambos deveriam ser identificados com a sua própria id-fluxo_transporte respectiva. Um indicador de bit é adicionado em um certo descritor de transmissão de banda larga para indicar a hierarquia do fluxo de transporte, para o qual o descritor está fornecendo a informação. Pela aplicação desta indicação de prioridade ou do indicador de prioridade, o receptor pode obter o mapeamento hierárquico de cada fluxo de transporte anunciado na informação administrativa da transmissão de banda larga.
