The objectives
of DANAE are to specify, develop, integrate and validate in a
realistic testbed a complete framework (with servers, network
devices and terminals) for context-aware, dynamic and flexible
media adaptation, delivery and consumption, able to provide end-to-end
quality of multimedia service at a minimal cost to the end-user.
An application will be specifically developed and implemented
on a demonstrator, to illustrate the pioneering service concepts
and features made possible by the Project
The work will cover: (i) the definition of scalable media formats
with their associated meta-data which provide, among others, information
on coding, online processing, intuitive content access, etc.,
(ii) the adaptation of scalable media resources to the session
context in a framework supporting dynamic and distributed adaptations,
as well as global optimization of fully featured multimedia scenes
comprising multiple resource types, i.e. not only single media
adaptation as is presently the case, but fully featured multimedia
scene adaptation through global optimization of audio, video,
2D graphics, 2D/3D virtual characters all together and (iii) the
transport and delivery of multimedia content to the end-user.
The specific constraints introduced by the multiplicity of networks
and terminals that may be involved in a communication session
will be considered for the design of error resilient and efficient
coding schemes. Efficiency is meant in terms of both bitrate and
required processing power in the player. The inter-relationship
of content adaptation and scalability with Digital Rights Management
(DRM) and charging issues – namely Service Tracking –
will also be explored.
