A Distributed Content Adaptation framework for Content Distribution Networks

The purpose of this research is to present topology aware overlays for efficient distributed multimedia application support. The discussed infrastructure for trans-coding multimedia streams uses self-organizing, resilient data distribution algorithms. The infrastructure takes into consideration the profile of communicating devices, network connectivity, exchanged content formats, context description, and available adaptation services to find a chain of adaptation services that could be applied to the content. Part of the infrastructure is a selection algorithm that finds the best sequence of adaptation services that can maximize the user’s satisfaction with the delivered content.
