<p>Disclosed is an adaptive estimation method of a multimedia data transmission rate. A transmission unit of a multimedia data transmission system transmits multimedia data to a reception unit through a RTP packet, the reception unit transmits state information of a network to the transmission unit through a RTCP receiver report packet, and the transmission unit detects a packet loss ratio from the RTCP receiver report packet and estimates an available transmission rate by a calculation method that varies according to a range within which the detected packet loss ratio falls into. Accordingly, the estimation method can speedily resolve network congestion when the packet loss is large.</p> |
