Abstract

"CONVERSãO DE FLUXO DE TRANSPORTE PARA FLUXO DE PROGRAMA". Um método para manter o sincronismo entre um fluxo de transporte e um decodificador do fluxo de programa durante uma conversão do fluxo de transporte para um fluxo de programa (FIG. 4). Um relógio de referência do sistema (SCR) é calculado a partir do fluxo de transporte (410). Uma taxa do multiplexador é calculada para o fluxo de programa (480). o fluxo do programa é formado pela multiplexação dos pacotes do fluxo elementar em pacotes (PES) analisados do fluxo de transporte usando a taxa do multiplexador calculada (480).
BRPI0214283A 2001-11-29 2002-11-14 método e dispositivo para manter o sincronismo entre um fluxo de transporte mpeg-2 que chega e um decodificador de fluxo de programa. BRPI0214283B1 (pt)
