In large scale IP Television (IPTV) and Mobile TV distributions, the video signal is typically encoded and transmitted using several quality streams, over IP Multicast channels, to several groups of receivers, which are classified in terms of their reception rate. As the number of video streams is usually constrained by both the number of TV channels and the maximum capacity of the content distribution network, it is necessary to find the selection of video stream transmission rates that maximizes the overall user satisfaction. In this presentation, we will present and discuss Dynamic Programming Multi-rate Optimization (DPMO) algorithm to efficiently solve this optimization problem.
