Abstract

SISTEMA DE DIFUSãO DE IP E MULTIPLEXADOR, APARELHO DE RECEPçãO E MéTODO USADO EM SISTEMA DE DIFUSãO DE IP. A prsente invenção refere-se a um sistema de difusão de IP que inclui um lado de transmissão (BS1 a BSn) e um lado de recepção (20) conectado ao lado de transmissão (BS1 a BSn) através de uma rede de difusão em uma rede de IP (NW). O lado de transmissão (BS1 a BSn) inclui um multiplexador (10), o qual gera um quadro de multiplexação padronizado in- cluindo pelo menos um campo de cabeçalho e um campo de informação pela multiplexação de uma pluralidade de pacotes de RTP. O lado de recepção (20) inclui um buifer (201), o qual mantém temporariamente o quadro de multiplexação a partir da rede de difusão e um reprodutor de programa (202, 203, 204), o qual recupera e analisa o quadro de multíplexação a partir do buffer (201), extrai um relógio de reprodução compartilhado por uma pluralidade de programas, demultiplexa uma pluralidade de TSs para cada programa a partir do quadro de multiplexação, e com base no relógio de reprodução reproduz o programa a partir de cada TS.
BRPI0800465A 2007-03-20 2008-03-10 sistema de difusão de protocolo de internet, multiplexador e aparelho de recepção usados em um lado de recepção do mesmo e método para converter uma pluralidade de fluxos de transporte em pacotes de protocolo de transporte em tempo real para uma transmissão de rede de protocolo de internet e transmitir os pacotes de rtp convertidos para uma rede de difusão na rede de ip BRPI0800465B1 (pt)
