Impact of video transcoding profiles in wireless multicast streaming
Estabraq H. Makiyah, Emad H. Al-Hemiary · 2012
Standards that have been made for every single thing can always be combined to achieve better ones. This paper presents a comparison between some of the video streaming profiles of different video codecs against transmission protocols. Experiments have taken place in a multicast environment in order to reach better receptions and bandwidth utilization. Using the new generation of the IEEE 802.11 standard, namely `n', the effect of hardware appliances and the indoor wave propagation have been taken into account. The results have shown that changing codecs corresponding to specific protocols can contribute in higher throughput with better video quality. Statistical analysis was done using SPSS17 performing multi-group ANOVA test has given enough evidence to reject the null hypothesis, and we are 95% confident that there is statistically significant difference in outputs, distances and frequencies with different pathways, namely (RTP, MPEG-2) profile.
