Those mechanisms have the capability to adapt the transmission of the multimedia data to network changes. In this paper, we describe a unicast mechanism for adaptive transmission of multimedia data, which is based on real time protocols. The proposed mechanism can be used for unicast transmission of multimedia data over heterogeneous networks, like the Internet, and has the capability to adapt the transmission of the multimedia data to network changes. Moreover, the proposed mechanism uses a “friendly” to the network users congestion control policy to control the transmission of the multimedia data. We evaluate the adaptive multicast transmission mechanism and we compare it with a number of similar mechanisms available to the literature (LBA, RAP, and TFRCP).1 aBouras, Christos1 aGkamas, Apostolos  uhttp://telematics.upatras.gr/telematics/publications/performance-adaptive-multimedia-transmission-case-unicast-technique?language=el
