3. Project ObjecHves
• To further develop an MPEG‐21 based QoS management
architecture and soluHons for cross‐layer adaptaHon and transport
of protected mulHmedia content over mulH‐domain heterogeneous
network infrastructures to diverse terminals
– Key elements of the project’s acHviHes
• Research
• InnovaHon
• StandardizaHon
• New business models
• To demonstrate the ENTHRONE soluHon in a large‐scale pilot, in
preparaHon for bringing it to the market
– Large scale end‐to‐end pilot able to demonstrate the capability of
ENTHRONE to manage, in an integrated way, the whole chain of
protected content handling, transport and delivery to user terminals
across heterogeneous networks, while offering QoS‐enabled services

Services, e.g., EIMS AdaptaHon Manager
– Add’l management subsystems for mulHcasHng, dynamic service management, caching and
content distribuHon networks
• Metadata Management
– Automated extracHon, gathering, and generaHon of metadata from real‐Hme/offline audio‐visual
streams and manifold metadata sources
– Metadata‐assisted content search
– Efficient approaches for management, transport and processing of content and context descripHve
metadata
• MPEG‐21‐based Cross‐Layer AdaptaHon Decision‐Taking
– DefiniHon of a Cross‐Layer AdaptaHon Model
– ImplementaHon of an interoperable Cross‐Layer AdaptaHon Decision‐Taking Engine (XL‐ADTE)
– DRM support for XL‐ADTE (in terms of permissible adaptaHons)
• Service Management and Monitoring
– MPEG‐21 for service level agreements and MPEG‐21 Event ReporHng for Service Monitoring
– NQoS‐to‐PQoS mapping
– Support for mulHcast‐based services and enabling QoS in access networks
• Caching and Content DistribuHon Networks
– IntegraHon of caching strategies in dynamic mulHmedia Caching Nodes
– Support for Content DistribuHon Network (CDN) deployment and management

10. EIMS Managers: Overview
• EIMS End‐to‐End QoS Manager – E2EQoSMngr
– Provisioning of the best Digital Item configuraHon (content,
metadata, structure) towards the content consumer ...
– … by uHlizing several informaHon assets (mainly metadata) from
all business actors along the delivery chain
• Available content variaHons and descripHon thereof
• CharacterisHcs of the available Television and MulHmedia (TVM)
processors
• CapabiliHes and condiHons of networks and end‐user terminals
• EIMS AdaptaHon Manager – AdaptMngr
– Provisioning of adaptaHon decisions according to dynamically
changing context condiHons (across service/network layers)
– Cross‐Layer AdaptaHon Decision‐Taking Engine (XL‐ADTE)
– Steers exactly one TVM (in a possible chain of TVMs)
2008/07/09 ChrisHan Timmerer, Klagenfurt University, Austria 10

11. EIMS Managers: Overview (cont’d)
• EIMS Caching and CDN Manager – CCDNMngr
– Provisioning of content (Digital Items) in a CDN including
ranking, placement, distribuHon, etc
– DefiniHon of Caching Policies to define local cache provisioning
parameters
• EIMS MulHcast Manager – MCastMngr
– Provisioning of mulHcast communicaHon services
– MulHcast overlay network
– Cross‐Layer mulHcast agent to take advantage of IP mulHcast in
the last core network domain (towards the content consumer)
• EIMS Metadata Manager – MetadataMngr
– Central component (MATool) responsible for metadata
collecHon, aggregaHon, conversion, etc.
