The
Cross-Layer Adaptation Decision-Taking Engine (XL-ADTE)
: The XL-
ADTE is part of an EIMS subsystem which provides the optimal parameter
settings for media resource engines (e.g., encoder, transcoder, streaming
server, etc. which are collectively referred to as television and multimedia
(TVM) processors), according to the EXLM by processing the metadata com-
pliant to MPEG-21 DIA. In other words, the XL-ADTE is a generic (soft-
ware) module that solves optimization problems [11] expressed by using
MPEG-21 DIA-based metadata according to the EXLM.
3 ENTHRONE Integrated Management Supervisor (EIMS)
3.1 Architecture Overview
The ENTHRONE Integrated Management Supervisor (EIMS) enables the de-
ployment of multimedia services allowing for end-to-end management with
QoS/QoE support across heterogeneous environments. Therefore, the EIMS pro-
vides a set of management subsystems, i.e., EIMS Managers, with predefined
functionalities and interfaces - based on Web Services and interoperable payload
formats - which enable the construction of ENTHRONE-based services according
to the requirements of various scenarios.
