MPEG-7 Harmonization with Dublin Core: Current Status and Concerns

This document presents the current status of the harmonization of MPEG-7 with Dublin Core. It provides mappings between both qualified and unqualified Dublin Core and MPEG-7 Descriptors (Ds) (in the context of their container Description Schemes (DSs)). This mapping also highlights a certain number of problems and concerns with the current MPEG-7 Multimedia DSs and Ds. Section 2 provides a brief overview of the Dublin Core Metadata Initiative. Section 3 provides a mapping between unqualified Dublin Core and MPEG-7 Ds and DSs. Section 4 provides a mapping between qualified Dublin Core (as recommended by the DC Usage Committee) and MPEG-7 Ds and DSs. Section 5 lists the concerns and issues with the MDS which have been raised as a result of performing these mappings

IPEA: the digital archive use case

Now is the time to migrate tape-based media archives to digital file-based archives for television broadcasters. These archives not only address the issue of tape-deterioration, they also create new possibilities for opening up the archive. However, the switch from tape-based to file-based is something only the very big television broadcasters can manage individually. Outer- broadcasters should work together to accomplish this task. In the Flemish part of Belgium, the two largest broadcasters in Flanders, namely the commercial broadcaster VMMa and the public broadcaster VRT, the television facilities supporting company Videohouse, and different university research groups associated with the Interdisciplinary Institute for Broadband Technology joined forces and started the "Innovative Platform on Electronic Archiving" project. The goal of this project is to develop common standards for the exchange and archiving of audio-visual data. In this paper, we give a detailed overview of this project and its different research topics

Design of a middleware for QoS-aware distribution transparent content delivery

Developers of distributed multimedia applications face a diversity of multimedia formats, streaming platforms and streaming protocols. Furthermore, support for end-to-end quality-of-service (QoS) is a crucial factor for the development of future distributed multimedia systems. This paper discusses the architecture, design and implementation of a QoS-aware middleware platform for content delivery. The platform supports the development of distributed multimedia applications and can deliver content with QoS guarantees. QoS support is offered by means of an agent infrastructure for QoS negotiation and enforcement. Properties of content are represented using a generic content representation model described using the OMG Meta Object Facility (MOF) model. A content delivery framework manages stream paths for content delivery despite differences in streaming protocols and content encoding. The integration of the QoS support, content representation and content delivery framework results in a QoS-aware middleware that enables representation transparent and location transparent delivery of content

Interactive Video Annotation Tool

Proceedings of: Forth International Workshop on User-Centric Technologies and applications (CONTEXTS 2010). Valencia, 7-10 September , 2010.Abstract: Increasingly computer vision discipline needs annotated video databases to realize assessment tasks. Manually providing ground truth data to multimedia resources is a very expensive work in terms of effort, time and economic resources. Automatic and semi-automatic video annotation and labeling is the faster and more economic way to get ground truth for quite large video collections. In this paper, we describe a new automatic and supervised video annotation tool. Annotation tool is a modified version of ViPER-GT tool. ViPER-GT standard version allows manually editing and reviewing video metadata to generate assessment data. Automatic annotation capability is possible thanks to an incorporated tracking system which can deal the visual data association problem in real time. The research aim is offer a system which enables spends less time doing valid assessment models.Publicad

Multimedia broadcast and internet satellite system design and user trial results

The EU funded project, System for Advanced Multimedia Broadcast and IT Services (SAMBITS), has created an enhanced and synchronised, multimedia terminal for merging satellite broadcast and internet telecommunication services in a way that efficiently combines the large bandwidth of the broadcast channel and the interactivity of the internet. This paper proposes a novel broadcast and internet service concept, illustrates this concept with two service scenarios and develops a system architecture to demonstrate the range of key benefits provided by these new technologies. It then describes the interactive multimedia terminal that was used for consuming this new service concept. Finally, the results of the user trials on the terminal are presented and discussed

Annotating Relationships between Multiple Mixed-media Digital Objects by Extending Annotea

Annotea provides an annotation protocol to support collaborative Semantic Web-based annotation of digital resources accessible through the Web. It provides a model whereby a user may attach supplementary information to a resource or part of a resource in the form of: either a simple textual comment; a hyperlink to another web page; a local file; or a semantic tag extracted from a formal ontology and controlled vocabulary. Hence, annotations can be used to attach subjective notes, comments, rankings, queries or tags to enable semantic reasoning across web resources. More recently tabbed Browsers and specific annotation tools, allow users to view several resources (e.g., images, video, audio, text, HTML, PDF) simultaneously in order to carry out side-by-side comparisons. In such scenarios, users frequently want to be able to create and annotate a link or relationship between two or more objects or between segments within those objects. For example, a user might want to create a link between a scene in an original film and the corresponding scene in a remake and attach an annotation to that link. Based on past experiences gained from implementing Annotea within different communities in order to enable knowledge capture, this paper describes and compares alternative ways in which the Annotea Schema may be extended for the purpose of annotating links between multiple resources (or segments of resources). It concludes by identifying and recommending an optimum approach which will enhance the power, flexibility and applicability of Annotea in many domains
