Transmissão de Vídeo sobre o Serviço ABR/ATM para Aplicações de Videoconferência, em Canais de Baixa Taxa de Bits

Alexandre M. MoraesJean-Marie Farines

In this article we present a model for video transmission over service ABR/ATM for videoconferece applications on low bitrate links, based in a rate controller that acts on the video encoder whose output feeds a buffer smooth the rate. The rate controller receives information of the state from ATM network through the feedback made by traffic management mechanism and, together with the buffer state information, it calculates a new transmission rate inside of the network limit allowed, keeping still the generated buffer delay inside of the imposed limit for the videoconference application interactivity feature.
