Abstract
In this paper we investigate technological solutions to improve the quality of video streaming in wireless networks. Specially developed programs are investigated that allow duplicating the packets of video streams. We conducted tests of video streaming with the duplication of all frames, key frames only and without duplication. Experiments have shown that the best result is obtained by the technology with duplication packets containing only key frames. We have found the coefficients for the most popular codecs, which describe the dependence of video quality on packet loss and delay variation.
