satisfactory level, even when facing adverse delivery conditions, without cost-
intensive subjective tests.
The remainder of this chapter is organized as follows. The high-level architec-
ture of ENTHRONE for end-to-end management enabling QoS/QoE is described
in Section 2. This section also highlights the cross-layer QoS adaptation concept.
Section 3 describes the EIMS with its functional building blocks and interfaces.
Finally, Section 4 describes how to measure the QoS/QoE for an MPEG-21-based
cross-layer multimedia content adaptation, and Section 5 concludes the chapter.
2 Architecture and Overall Concept
2.1 End-to-End Management Enabling QoS/QoE
The ENTHRONE high-level architecture for end-to-end management enabling
QoS is given in Fig. 1 which comprises three layers:
The top layer is the supervision layer which role is to manage and to monitor
the services that participate in the content delivery chain. It is implemented by the
ENTHRONE Integrated Management Supervision (EIMS), which uses MPEG-21
