Influence of distortions of key frames on video transfer in wireless networks
In this paper, it is shown that for substantial increase of video quality delivery in wireless networks, it is necessary to execute two important enhancements to existing communication schemes: (i) the video player on the receiver side should selectively discard duplicated RTP packets, and (ii) server of streaming video should duplicate the packets containing the information of key frames. Coefficients of the mathematical model to assess video quality have been found for WiFi and 3G standards-compliant wireless networks that employ MPEG-2 and MPEG-4 (DivX) codecs. We also present a novel experimental technique that enabled us to collect and process the quantitative datasets used in our modeling study.
