Architecture for adaptive and secure content delivery through multiple networks

A system for adaptable and secure content delivery and its architecture is described in the present paper. The system is based on the MPEG-21 standard, which provides the architecture with flexibility, interoperability and adaptability. The described structure has been designed with the suitable mechanisms to ensure a correct content management use, so no-one can have illegal access to a single piece of content, and it has also been designed to provide adaptability in such a way that different kind of devices can have access to the system. Moreover, the presented architecture is prepared to be used in different network types.
