Estimating MPEG-4 Video Transmission over Gilbert Wireless Channels


In this paper, the aim is to propose an analytical packet loss models to estimate the video quality for MPEG-4 video transmission over error-prone correlated wireless channels. Two packet loss models are considered at the packet level in the network layer using TCP-Friendly protocol: (i) Gilbert-Elliott Model (GEM) and (ii) Extended Gilbert Model (EGM). The resultant video quality in terms of playable frame rate (PFR) is estimated at the end client over wireless cellular network. The obtained results point out the effect of packet correlation factor on the perceived video quality under different conditions of packet loss probability. It is found that the proposed EGM model outperforms in estimating the perceived video quality
