Application Layer Multicast for Video Streaming Applications - 12/19/2008

Hasti Ahlehagh

Streaming media and IPTV are to bring high quality video to the end users over the internet. IPTV is likely to use an application layer multicast protocol to distribute the video to different users interested in the same content. In this presentation, we are going to study a tree based application layer multicast topology known as NICE application layer multicast and evaluate end user video quality experience using the PSNR and SSIM video quality metrics. We show that clustering nodes based on upload bandwidth and modifying the original video quality in a lower quality clusters results in a better overall user experience. For this study we used ns-2 to simulate the network and ffmpeg tool for H.264/MPEG-4 codec.
