Scalable content delivery over P2P convergent networks

This paper describes an innovative system and its architecture to offer media scalable content delivery, increasing the robustness and resiliency, enriching the PQoS both within the network and/or at the end-user terminal, while protecting the content from unauthorized access over heterogeneous physical architecture and P2P logical overlay network topologies. The system is focused on different convergent networks including broadcasting, interactive/on demand bidirectional networks and mobile networks, and mesh P2P logical overlay topologies. This system is based on three technology pillars: Multi-layered/Multi-viewed content coding, Multi-source/multi-network streaming & adaptation, content protection and lightweight asset management. In addition, the applicability to IPTV over P2P convergent networks is described to demonstrate the system usefulness to offer commercial services.
