Abstract

"MéTODO DE ESTIMATIVA ADAPTáVEL DE TAXA DE TRANSMISSãO DE DADOS MULTIMìDIA". é revelado um método de estimativa adaptável de uma taxa de transmissão de dados multimídia. Uma unidade de transmissão de um sistema de transmissão de dados multimídia transmite dados multimídia para uma unidade de recepção através de um pacote RTP, a unidade de recepção transmite informação de estado de uma rede para a unidade de transmissão através de um pacote de relatório do receptor RTCP, e a unidade de transmissão detecta uma proporção de perda de pacote a partir do pacote de relatório do receptor RTCP e estima uma taxa de transmissão disponível por um método de cálculo que varia de acordo com uma faixa dentro da qual a proporção de perda de pacote detectada se situa. Por conseqüência, o método de estimativa pode rapidamente resolver o congestionamento da rede quando a perda de pacote é grande.
