Abstract
"MéTODO PARA ADAPTATIVAMENTE CONTROLAR O NìVEL MáXIMO DA MEMóRIADO RECEPTOR NO CLIENTE EM UM SISTEMA DE TRANSMISSãO DE MULTIMìDIA, SISTEMA DE CONTROLE ADAPTATIVO, E, DISPOSITIVO DE COMUNICAçãO". Método para prover para o transmissor (20) dos pacotes RTP, o nível máximo (54) atual da memória (50) do receptor no receptor dos pacotes RTP em um certo instante de tempo representado como a duração do tempo de reprodução restante. O receptor envia em um relatório RTCP (26), o número seqüencial de um pacote RTP selecionado na memóriado receptor e a diferença de tempo entre o tempo de reprodução programado deste pacote e o tempo atual. Baseado na informação de temporização, o transmissor calcula a quantia de tempo que este levaria para esvaziar a memória do receptor, se o receptor continuar a reprodução em uma velocidade normal e nenhum outro pacote RTP chegar na memória do receptor. Esta informação do nível máximo da memóriado receptor pode ser usada no transmissor para ajustar a taxa de transmissão e/ou a taxa de reprodução nominal dos pacotes RTP, de forma a manter o nível máximo indicado da memória do receptor.
