Adaptive method for multimedia transmission rate estimation based on rtcppacket

The present invention, the adaptive, depending on that, in the RR (Receiver Report) packet of the RTCP packet is received from the receiving terminal, detects a packet loss rate, the detected packet loss ratio according to the adaptive multimedia data rate estimation method for the RTCP packet based estimated by modifying the available transmission rate, it is one to reduce the congestion of the network. To this end, the present invention is a process of transmitting the RTP packet to a receiver, receiving the RTCP packet from the receiving end and; Process of identifying the packet loss rate by extracting a RR (Receive Report) of the RTCP packet; Is between performing the procedure for calculating the estimated available transmission rate based on the packet loss rate, different methods, the process of calculating the estimated available transmission rate, packet loss rate is a first threshold and a second threshold value, a mathematical expression to use will be configured to include a step of setting the estimated available transmission rate. Formula; Here, s is the size of the packet, p is the packet loss rate, LSR (t
