Simulation of packet losses in video transfers using real-time transport protocol

Multimedia content transmitted over unreliable environment, like wireless channels or in generally any network with unreliable transport protocol, is always subject to packet loss due to network congestion and channel noise. By using compressed video, errors could propagate to the subsequent frames...

Description
Summary:Multimedia content transmitted over unreliable environment, like wireless channels or in generally any network with unreliable transport protocol, is always subject to packet loss due to network congestion and channel noise. By using compressed video, errors could propagate to the subsequent frames with resulting worse video quality. Therefore it is necessary to study impact of packet loss on overall video quality. First step in such study is creation of network models. The most popular approach is network modeling using Markov chains. In our paper we have analyzed in which way have occurred packet losses during transmission of video through wired and also wireless network.
