Abstract

PROCESSO DE MULTIPLEXAçãO MULTIMìDIA Proporciona-se um processo de multiplexação para comunicação multimídia, que se apresenta compatível com o protocolo H.223 através de alteração de um cabeçalho de uma unidade de dados de protocolo multiplex (MUX-PDU). O processo de multiplexação inclui as etapas de codificação de dados de mídia, e multiplexação dos dados de mídia codificados na etapa (a) em unidades de uma composição pré-determinada, e introdução de um segundo indicador apresentando uma extensão pré-determinada com uma auto-correlação na composição após um primeiro indicador ter a abertura e fechamento da composição. Portanto, a probabilidade de detecção do MUX-PDU através de um receptor é aumentada pela adição de um indicador apresentando uma alta auto-correlação à composição MUX-PDU, aumentando assim a resiliência ao erro.
