Abstract

Allowing the description of the structure of documents has been one of the key factors for the success of the hypertext markup language (HTML) family of markup languages. This capability has motivated the phenomenon that has become known as the World Wide Web (the "Web"). The next generation of the Web, known as the Semantic Web (Berners-Lee, Hendler. & Lassila, 2001), aims at describing the meaning rather than the structure of data, adding more intelligent search, retrieval, and other agent functionalities to the Web, and tools that make the implementation of this Semantic Web possible are greatly needed. The increasing availability of multimedia on the World Wide Web makes metadata description efforts for multimedia a pressing need, yet with the volume of content being created, often only a rudimentary description of the multimedia content is available. In addition, the digital mode entails a host of other descriptive needs, such as the format, factors such as compression and transmission, and issues such as copyright restrictions and terns for usage. Thus, new and efficient ways of describing multimedia content and meaning are needed as well as a structure that is capable of carrying such descriptions. Several attempts have been made to grapple with this issue using descriptive metadata, one of the earliest of which was the revision of the Dublin Core to ascertain essential features necessary to resource discovery of visual items in a networked environment (Weibel & Miller, 1997). Other metadata schemes, such as the Visual Resources Association Core Categories (http://www.vraweb.org/vracore3.htm), also include format information necessary to the use and display of digital images.

Abstract

Improvements in network bandwidth along with dramatic drops in digital storage and processing costs have resulted in the explosive growth of multimedia (combinations of text, image, audio, and video) resources on the Internet and in digital repositories. A suite of computer technologies delivering speech, image, and natural language understanding can automatically derive descriptive metadata for such resources. Difficulties for end users ensue, however, with the tremendous volume and varying quality of automated metadata for multimedia information systems. This lecture surveys automatic metadata creation methods for dealing with multimedia information resources, using broadcast news, documentaries, and oral histories as examples. Strategies for improving the utility of such metadata are discussed, including computationally intensive approaches, leveraging multimodal redundancy, folding in context, and leaving precision-recall tradeoffs under user control. Interfaces building from automatically generated metadata are presented, illustrating the use of video surrogates in multimedia information systems. Traditional information retrieval evaluation is discussed through the annual National Institute of Standards and Technology TRECVID forum, with experiments on exploratory search extending the discussion beyond fact-finding to broader, longer term search activities of learning, analysis, synthesis, and discovery.

Abstract

Although database technology is well established, multimedia storage and access of digital image, sound and video material is much more recent. Although most film and video material is intrinsically multimedia it is not interactive. Unlike traditional data, multimedia has a very free format and has mostly lost the constraint of human language. The problems of interactive multimedia publications arise not just in user access but from the internal structuring of the database. Discusses topics related to methods of access to data and the design approaches to this covering multimedia material, database technology, indexing and referencing techniques and design and production

Abstract

A database management system is a general-purpose software system that facilitates the processes of defining, constructing, and manipulating databases for various applications. This article investigates the role of data management in multimedia digital libraries, and its implications for the design of database management systems. The notions of content abstraction and content independence are introduced, which clearly expose the unique challenges (for database architecture) of applications involving multimedia search. A blueprint of a new class of database technology is proposed, which supports the basic functionality for the management of both content and structure of multimedia objects

Abstract

Discusses an architecture for knowledge-based hypermedia systems based on work from semantic databases. Its power derives from its use of a single, uniform data structure which can be used to store both the intensional and extensional information needed to generate hypermedia systems. The architecture is also sufficiently powerful to accomodate the representation of reasonable amount of knowledge within a hypermedia system. Work has been conducted in building a number of prototypes on a small information base of digital image data. The prototypes serve as demonstrators of systems for managing the large amount of information held by museums of their artifacts. The aim of this work is to demonstrate the flexibility of the architecture in sereving the needs of a number of distinct user groups. The first prototype has demonstrated that the virtual architecture is capable of supporting some of the main hypermedia access methods. The current demonstrator is being used to investigate the potential of the approach for handling multiple classifications of hypermedia material. The research is particularly directed at the incorporation of evolving temporal and spatial knowledge

Abstract

Das vorliegende Buch handelt von den Technologien zum Austausch medialer Inhalte. Die Inhalte werden seit geraumer Zeit vornehmlich in digitaler Form dargestellt, was mit vielen Vorteilen für die Produzenten und Konsumenten verbunden ist. Positive Aspekte erstrecken sich sowohl auf die mögliche Qualität als auch auf die Handhabung und den erleichterten Umgang. Seit Beginn des 21. Jahrhunderts gibt es nun einen neuen Entwicklungsschritt, der als zweite Phase der Digitalisierung bezeichnet werden kann. Diese ist dadurch gekennzeichnet, dass die medialen Inhalte, oft auch als Content bezeichnet, in sehr vielen Fällen in datenreduzierter Form digital gespeichert und verteilt werden. Auch die Akquisition bezieht vermehrt Datenreduktion mit ein. Der Datenreduktion und den Datenformaten (File-Formate), unter denen die Inhalte ausgetauscht werden, kommen in dieser Phase eine zentrale Bedeutung zu. Damit die einzelnen Kommunikationspartner einander auch in dieser neuen Ära verstehen können, d. h. die Kommunikation ohne großen Aufwand, respektive ohne merklichen Qualitätsverlust stattfinden kann, ist eine Standardisierung sowohl der Datenreduktionsalgorithmen als auch der File-Formate erforderlich, und genau dies ist Gegenstand dieses Buches.

Abstract

Personal video recorders have the capability to change the media delivery industry fundamentally, and in this context, many believe the real international age of personal digital recorders (PDRs) will arrive with the use of "open" systems. The world reached an important milestone with the publication of the TV-Anytime Phase 1 specifications for unidirectional broadcast and metadata services over bidirectional networks. TV-Anytime is a worldwide pre-standardization body; this article gives an overview of the main features of TV-Anytime's metadata specification and its relationship to MPEG-7 and provides insight into ways two organizations concerned with standards work together. Phase 2 has since been completed and TV-Anytime has been adopted by various international standards organizations dealing with telecommunications and is now in the implementation phase.

Abstract

EC project PRESTO has completed a survey of the holdings and preservation status of ten major broadcast archives. These archives represent a significant portion of total European broadcast archives, including some ofthe largest individual collections.The main findings are that approximately 75% of this material is at risk or inaccessible and that the collections are growing at roughly four times the rate of current progress in preservation work. This article gives detailed results of the survey, and describes the technical developments being produced by project PRESTO to reduce the costs and improve the effectiveness of multimedia archive preservation projects.

Abstract

The library at Napier University in Edinburgh recently acquired a large collection of printed music, long playing records and compact discs which it was asked to catalogue as soon as possible.
