    Abstract
    Andreas erste Schritte, Fabians Einschulung, Helgas letzter Mallorca-Urlaub und Werners Hochzeit, fast immer ist die Kamera zur Stelle und immer öfter ist es eine Digitalkamera. Manchmal werden die Bilder später eingescannt und das Fotolabor presst sie direkt auf CD-ROM. Sogar übers Internet kann man sich neuerdings Fotos 'entwickeln' und zukommen lassen. Diese digitale Bilderflut würde unweigerlich ins Chaos führen, gäbe es nicht preiswerte Bilddatenbanken für den heimischen PC

    Abstract
    Die elektronische Distribution auch für digitalisierte Videos und Bilder zu nutzen ist Ziel zahlreicher Überlegungen. Damit wird nicht nur die Verfügbarkeit der bislang nur über die Ausleihe vertriebenen Titel am Lernort erheblich verbessert. Die Integration von Internet, Software und digitalen Videos wird aber auch ganz neue didaktische Konzepte für das Lernen und Lehren ermöglichen. Das Potenzial wird noch einmal dadurch gesteigert, wenn zusätzlich digitale Medienmodule (Videoclips, Grafiken, Tondateien, Texte usw.) produziert und angeboten werden können. In dem im Landkreis München begonnenen Projekt BMOD wird die Distribution und Nutzung von digitalisierten FWU-Medien in einem kommunalen Intranet erprobt

    Das leidige Problem: Die Programme von Premiere World sind über den iesy-Dekoder nicht zu empfangen. Umgekehrt können die hessischen Premiere-Abonnenten mit ihrer d-box die iesy-Angebote nicht sehen. Denn statt des umstrittenen Digitalkastens aus München hat sich eKabel für eine Settop-Box des US-Herstellers Motorola entschieden. Sie arbeitet mit einer Software des amerikanischen Unternehmens Liberate und entschlüsselt alle Digitaldienste mit dem Motorola-System MediaCipher. Wer iesy-TV und die Premiere Aboprogramme der Münchner Kirch-Gruppe empfangen will, müsste sich also zwei digitale Empfangsgeräte anschaffen - eine für den Zuschauer missliche Situation. "Mit der Einspeisung der Premiere-Programme in unsere Netze verdienen wir fast nichts. Gespräche mit Kirch über ein neues Geschäftsmodell waren aber bisher erfolglos. Außerdem holt die d-box das Internet nicht auf den Fernsehschirm", begründet Geschäftsführer Günter Maier das Vorgehen von eKabel. Kirch-Sprecher Hartmut Schultz erklärt zu dem Thema lapidar, es gebe zwar Kontakte zu allen Kabelgesellschaften, aber noch keine konkreten Geschäftsmodelle". Obwohl die Kirch-Gruppe kürzlich angedeutet hatte, ihre Pay-TV-Pakete demnächst auch über andere Digitaldekoder als die d-box zu vermarkten, scheint das zumindest in Hessen noch in weiter Ferne zu liegen. Doch was bietet eKabel seinen Kunden? Zunächst ein Basispaker mit 33 analogen Fernsehprogrammen und 40 Radiosendern Die dafür zu entrichtende Kabelgrundgebühr schwankt in Hessen zwischen 15,60 Mark und 26,90 Mark. Neu ist das digitale Paket Basis plus, das Kunden für 19,60 Mark im Monat extra abonnieren können. Für sein Geld erhält der Zuschauer eine Settop-Box ins Haus gestellt, die an den Fernseher angeschlossen wird und die technische Voraussetzung für den Empfang von Digitaldiensten schafft. Mit dem Dekoder können im Basis plusPaket zehn neue digitale Spartenkanäle empfangen werden. Dabei handelt es sich um Special-interest-Sender wie Eurosportnews (Sportnachrichten), Wine & Dine (Gastronomie), Leonardo (Wissen) oder Marco Polo (Reise). Eine elektronische Programmzeitschrift, im Branchenjargon EPG - Electronic Program Guide. genannt - liefert auf Knopfdruck eine Ubersicht der neuen Programminhalte am Bildschirm. Vor allem ermöglicht die digitale Box das Versenden von E-Mails und das Abrufen von ausgewählten Internetseiten auf dem Fernsehgerät. Hierfür stellt eKabel Nutzern ein drahtloses Keyboard zur Verfügung, mit dem Webadressen und Texte der elektronischen Post eingegeben werden können. Im Basis plus-Tarif istjeweils eine Mailadresse pro Familienmitglied enthalten. Demnächst soll auch der elektronische Einkauf ("Homeshopping") am Fernseher Realität werden; insgesamt fünf Shoppingkanäle werden Zuschauern dann ihre Produkte zur Direktbestellung anpreisen. Laut eKabel-Geschäftsführer Maier ist das nur der erste Schritt zum weiteren Ausbau der iesy-TV-Angebote. Zusätzliche Digitalsender - darunter auch Spezialbouquets für ausländische Zuschauer - werden die Basispakete ergänzen, in einigen Monate sollen das Abonnement einzelner Kanäle (Pay-per-channel) sowie das Bestellen einzelner Spielfilme (Video on Demand) möglich werden. Auch für einen Hochgeschwindigkeitszugang ins Internet für den PC via Modem (iesy Net) sowie die Möglichkeit, über das Kabelnetz preiswert zu telefonieren (iesy Phone), will das Untemehmen so rasch wie möglich eine große Zahl von Kunden begeistern. Allerdings wird es rund vier Jahre dauern, bis die neuen Multimediadienste im gesamten Netz verfügbar sein werden, an dem heute 1,3 Millionen der 2,7 Millionen hessischen Haushalte hängen. Um die Strippen technisch aufzurüsten, will eKabel, das von dem britischen Telekom-Untemehmen National Transcommunications Limited (NTL) kontrolliert wird, 1,8 Milliarden Mark investieren. Langfristig will das Unternehmen 40 Prozent des Umsatzes mit Fernsehangeboten, etwa 30 Prozent mit Kabeltelefonie und ebenso viel mit Intemetdiensten und Geschäftskunden erwirtschaften. eKabel hatte vor einem Jahr 65 Prozent der zuvor im Alleinbesitz der Deutschen Telekom befindlichen Kabelanlagen erworben und dafür nach Schätzungen zwischen zwei und drei Milliarden Mark bezahlt.

    Abstract
    Traditional query methods are good at retrieving items an the basis of a precise specification, but they are not useful when the user wants to explore an information base in order to find interesting items. Dynamic Taxonomies were recently proposed for guided browsing and retrieval from heterogeneous information bases. We discuss their application to multimedia information bases and provide an example of interaction.

    Abstract
    This paper considers the issues surrounding the fit between information systems and organisation structures. The paper uses philosophical ideas concerning knowledge and applies them to organisational design and information processing in order to encourage alternative perspectives and new ideas. This is achieved by a discussion of the issues surrounding organisational design and the impact of design on information processing; an overview of the ideas concerning the theory of knowledge proposed from both a rational and an empirical viewpoint and how these relate to other epistemological theories such as historicism and pragmatism. The paper closes with a discussion of the means by which philosophical considerations can assist towards new forms of information processing.

    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
    Multimedia retrieval is a complex and to some extent still unexplored area. Based on a full year of e-mail requests addressed to a large film archive this study analyses what types of information needs real users have and how these needs are expressed. The findings include that the requesters make use of a broad range of need attributes in specifying their information needs. These attributes relate to the production, content, subject, context and screening of films. However, a few attributes - especially title, production year and director - account for the majority of the attribute instances. Further, as much as 43 per cent of the requests contain no information about the context that gives rise to the request. The current indexing of the archived material is restricted to production-related attributes, and access to the material is, thus, frequently dependent on the archivists' extensive knowledge of the archived material and films in general.

    Abstract
    Purpose - The aim of this paper is to ask why the libraries and the computer and media centres of German universities are picking up too little to improve the conditions for learning, teaching and research. Design/methodology/approach - With the founding of the Information, Communication and Media Center/Informations-, Kommunikations- und Medienzentrums (ICMC/IKMZ), the central services of the Brandenburg Technical University of Cottbus (BTU Cottbus) library, computer center, multimedia center and administrative data processing were combined on a common management level, and the prerequisites for the development of integrated information management were created. Findings - On this basis the following goal was set: the realization of more efficient organizational structures for a broad spectrum of customer- and service-oriented information, communications and media (ICM) offers for research, teaching and administration. Originality/value - The paper gives an overview of German discussion on the convergence of services, and presents the ICMC/IKMZ of Cottbus University as an example of a converged institution.

    Abstract
    Multimedia is proliferating on Web sites, as the Web continues to enhance the integration of multimedia and textual information. In this paper we examine trends in multimedia Web searching by Excite users from 1997 to 2001. Results from an analysis of 1,025,910 Excite queries from 2001 are compared to similar Excite datasets from 1997 to 1999. Findings include: (1) queries per multimedia session have decreased since 1997 as a proportion of general queries due to the introduction of multimedia buttons near the query box, (2) multimedia queries identified are longer than non-multimedia queries, and (3) audio queries are more prevalent than image or video queries in identified multimedia queries. Overall, we see multimedia Web searching undergoing major changes as Web content and searching evolves.

    Abstract
    A model for analysing multimedia information is proposed from the point of view of the theory of communication. After a brief presentation of the complex map of the sciences that deal with multimedia communication in its different aspects, the current multimedia revolution is historically contextualized as a tendency towards messages that are able to build near-reality experiences (virtual reality). After setting the theoretical point of view, an analysis of multimedia messages is substantiated and a model is presented. The first part of the model deals with the different communications channels and tools: still images, movies, sounds, texts, text with illustrations, audiovisuals and interactive multimedia, with an emphasis in nontextual documents. The second part addresses the global properties of the multimedia message, which are of a textual and metatextual nature. The overlapping of media, channels, genres and messages-and the conscious and technical use of such interactions-is precisely one of the main and outstanding characteristics of the multimedia discourse, and requires specific moves in indexing languages development. The multimedia environment has also a great potential to promote a wider theory of knowledge organization, bringing closer distant fields like scientific and fictional indexing or verbal and image indexing. It is stated that such a unified theory requires a closer attention to the pragmatic aspects of indexing and the inclusion of new semantic layers. A simple indexing model is proposed to illustrate who to address these challenges.

    Abstract
    The MPEG-7 standard supports the description of both the structure and the semantics of multimedia; however, the generation and consumption of MPEG-7 structural and semantic descriptions are outside the scope of the standard. This article presents two research prototype systems that demonstrate the generation and consumption of MPEG-7 structural and semantic descriptions in retrieval applications. The active system for MPEG-4 video object simulation (AMOS) is a video object segmentation and retrieval system that segments, tracks, and models objects in videos (e.g., person, car) as a set of regions with corresponding visual features and spatiotemporal relations. The region-based model provides an effective base for similarity retrieval of video objects. The second system, the Intelligent Multimedia Knowledge Application (IMKA), uses the novel MediaNet framework for representing semantic and perceptual information about the world using multimedia. MediaNet knowledge bases can be constructed automatically from annotated collections of multimedia data and used to enhance the retrieval of multimedia.
