In this paper, we introduce a Media Decision Taking Engine (MDTE), enabling the automatic selection and/or rating of multimedia content versions, based on the available context information. The presented approach is fully semantic-driven, which means that we not only semantically model the context information, but also the decision algorithms themselve, which are represented in N3Logic, a rule language that extends RDF. The decision rules are based on a rating function, supporting the specification of weights and affinity parameters for each environment property. Finally, we show how the MDTE is integrated in a media delivery platform, using the provisions of the existing Web infrastructure.

Moving picture experts group (MPEG) standards provide tools for a broad range of purposes, covering from coding to metadata description tools. In this paper, the combined use of tools from different MPEG standards is described in the context of a video summarization application. The main objective of the framework is the efficient generation of summaries, integrated with their adaptation to the user's terminal and network. The MPEG-4 Scalable Video Coding specification is used for fast adaptation and summary bitstream generation. MPEG-21 digital item adaptation tools are used to describe metadata related to the user's terminal and network. MPEG-7 tools are used to describe the summary. Finally, the framework is compared with alternative approaches (variations and transcoding), in terms of efficiency, rate-distortion performance and other aspects. Downloaded from FIGURE 7.

“…One of the keys in the design of our NinSuna platform is the datablock-based index for the media repository. This index is based on a model for media resources describing the high-level structure of media resources in terms of Random Access Units (RAUs) 7 and corresponding data blocks [18]. More specifically, for each track of the media resource, we describe the list of RAUs.…”

“…More specifically, our model for media resources is implemented in the Web Ontology Language (OWL, [9]); thus the instances of the model (i.e., the index) are represented in the Resource Description Format (RDF, [8]). Additionally, data blocks are retrieved by means of SPARQL Protocol And Query Language (SPARQL, [13]) queries [18]. …”

The current Web specifications such as HTML still treat video and audio resources as 'foreign' objects on the Web, especially lacking a transparent integration with current Web content. The Media Fragments URI specification is part of various efforts at W3C trying to make media a "first class citizen" on the Web. More specifically, with a Media Fragment URI, one can point to a media fragment by means of a URI, enabling people to identify, share, link, and consume media fragments in a standardized way. In this paper, we propose and evaluate a number of implementation strategies for Media Fragments. Additionally, we present two optimized implementation strategies: a Media Fragment Translation Service allowing to keep existing Web infrastructure such as Web servers and proxies and a fully integrated Media Fragments URI server that is independent of underlying media formats. Finally, we show how multiple bit rate media delivery can be deployed in a Media Fragments aware environment, using our Media Fragments URI server.
