Multimedia delivery in the future internet
The term “Networked Media” implies that all kinds of media including text, image, 3D graphics, audio
and video are produced, distributed, shared, managed and consumed on-line through various networks,
like the Internet, Fiber, WiFi, WiMAX, GPRS, 3G and so on, in a convergent manner [1]. This white
paper is the contribution of the Media Delivery Platform (MDP) cluster and aims to cover the Networked
challenges of the Networked Media in the transition to the Future of the Internet.
Internet has evolved and changed the way we work and live. End users of the Internet have been confronted
with a bewildering range of media, services and applications and of technological innovations concerning
media formats, wireless networks, terminal types and capabilities. And there is little evidence that the pace
of this innovation is slowing. Today, over one billion of users access the Internet on regular basis, more
than 100 million users have downloaded at least one (multi)media file and over 47 millions of them do so
regularly, searching in more than 160 Exabytes1 of content. In the near future these numbers are expected
to exponentially rise. It is expected that the Internet content will be increased by at least a factor of 6, rising
to more than 990 Exabytes before 2012, fuelled mainly by the users themselves. Moreover, it is envisaged
that in a near- to mid-term future, the Internet will provide the means to share and distribute (new)
multimedia content and services with superior quality and striking flexibility, in a trusted and personalized
way, improving citizens’ quality of life, working conditions, edutainment and safety.
In this evolving environment, new transport protocols, new multimedia encoding schemes, cross-layer inthe
network adaptation, machine-to-machine communication (including RFIDs), rich 3D content as well as
community networks and the use of peer-to-peer (P2P) overlays are expected to generate new models of
interaction and cooperation, and be able to support enhanced perceived quality-of-experience (PQoE) and
innovative applications “on the move”, like virtual collaboration environments, personalised services/
media, virtual sport groups, on-line gaming, edutainment. In this context, the interaction with content
combined with interactive/multimedia search capabilities across distributed repositories, opportunistic P2P
networks and the dynamic adaptation to the characteristics of diverse mobile terminals are expected to
contribute towards such a vision.
Based on work that has taken place in a number of EC co-funded projects, in Framework Program 6 (FP6)
and Framework Program 7 (FP7), a group of experts and technology visionaries have voluntarily
contributed in this white paper aiming to describe the status, the state-of-the art, the challenges and the way
ahead in the area of Content Aware media delivery platforms
aDORe: a modular, standards-based Digital Object Repository
This paper describes the aDORe repository architecture, designed and
implemented for ingesting, storing, and accessing a vast collection of Digital
Objects at the Research Library of the Los Alamos National Laboratory. The
aDORe architecture is highly modular and standards-based. In the architecture,
the MPEG-21 Digital Item Declaration Language is used as the XML-based format
to represent Digital Objects that can consist of multiple datastreams as Open
Archival Information System Archival Information Packages (OAIS AIPs).Through
an ingestion process, these OAIS AIPs are stored in a multitude of autonomous
repositories. A Repository Index keeps track of the creation and location of
all the autonomous repositories, whereas an Identifier Locator registers in
which autonomous repository a given Digital Object or OAIS AIP resides. A
front-end to the complete environment, the OAI-PMH Federator, is introduced for
requesting OAIS Dissemination Information Packages (OAIS DIPs). These OAIS DIPs
can be the stored OAIS AIPs themselves, or transformations thereof. This
front-end allows OAI-PMH harvesters to recurrently and selectively collect
batches of OAIS DIPs from aDORe, and hence to create multiple, parallel
services using the collected objects. Another front-end, the OpenURL Resolver,
is introduced for requesting OAIS Result Sets. An OAIS Result Set is a
dissemination of an individual Digital Object or of its constituent
datastreams. Both front-ends make use of an MPEG-21 Digital Item Processing
Engine to apply services to OAIS AIPs, Digital Objects, or constituent
datastreams that were specified in a dissemination request.Comment: Draft of submission to Computer Journa
Audiovisual preservation strategies, data models and value-chains
This is a report on preservation strategies, models and value-chains for digital file-based audiovisual content. The report includes: (a)current and emerging value-chains and business-models for audiovisual preservation;(b) a comparison of preservation strategies for audiovisual content including their strengths and weaknesses, and(c) a review of current preservation metadata models, and requirements for extension to support audiovisual files
BlogForever: D3.1 Preservation Strategy Report
This report describes preservation planning approaches and strategies recommended by the BlogForever project as a core component of a weblog repository design. More specifically, we start by discussing why we would want to preserve weblogs in the first place and what it is exactly that we are trying to preserve. We further present a review of past and present work and highlight why current practices in web archiving do not address the needs of weblog preservation adequately. We make three distinctive contributions in this volume: a) we propose transferable practical workflows for applying a combination of established metadata and repository standards in developing a weblog repository, b) we provide an automated approach to identifying significant properties of weblog content that uses the notion of communities and how this affects previous strategies, c) we propose a sustainability plan that draws upon community knowledge through innovative repository design
