Reconfigurable Channel Reordering To Reduce Latency In IPTV Networks

The latency is a critical issue in the Internet Protocol Television (IPTV) Quality of Experience (QoE) and Quality of Service (QoS) performance. Bandwidth limitations prevent the clients from receiving all the channels at once. Latency problem in IPTV networks is reduced by a channel reordering technique that exploits the differing keyframe delivery times for the adjacent sessions to arrange the switching order during the surfing periods. In this paper, we propose the reconfigurable channel reordering technique that adapts itself when a new channel is introduced into the system, without redefining the system. It is efficient in terms of reconfigurable system design with the dynamic channel reordering.
