Abstract EN
We investigate the video assignment problem of a hierarchical Video-on-Demand (VOD) system in heterogeneous environments where different quality levels of videos can be encoded using either replication or layering.
In such systems, videos are delivered to clients either through a proxy server or video broadcast/unicast channels.
The objective of our work is to determine the appropriate coding strategy as well as the suitable delivery mechanism for a specific quality level of a video such that the overall system blocking probability is minimized.
In order to find a near-optimal solution for such a complex video assignment problem, an evolutionary approach based on genetic algorithm (GA) is proposed.
From the results, it is shown that the system performance can be significantly enhanced by efficiently coupling the various techniques.
