    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
    Wenn man Presseveröffentlichungen als Basis nimmt, so deckt die Bezeichnung 'Multimedia' einen Bereich ab, der von der Spiele-CD-ROM über multimediale Shows und das Video-Document-Conferencing bis hin zum Internet und zum interaktiven Fernsehen reicht. Manche Experten betrachten zwar das Computer-Based-Training (CBT) als eine der zentralen Anwendungen im Bereich Multimedia, aber schaut man sich einmal die Anwendungen an, die aus der Sicht der Anbieter 'Zielmärkte' sind, so trifft man meist auf Begriffe wie Präsentation, Werbung, Verkaufsförderung, Unternehmenskommunikation und Schulung. Zu einer Definition oder Abgrenzung sind solche Schlagworte wertlos. Eine klare Definition ist aber unbedingt erforderlich, wenn es um die Anschaffung entsprechender Multimedia-Entwicklungs-Software geht

    Abstract
    Presents a model of hypermedia that allows the combination of 'hyperstructured' information with dynamic multimedia information. The model is derived by extending the Dexter hypertext reference model and the Centrum voor Wiskunde en Informatica Multimedia Interchange Format (CMIF) multimedia model. Explains how the CMIF multimedia model builds on the model provided by Dexter. The Amsterdam hypermedia model enables the description of structured multimedia documents, incorporating time at a fundamental level and extending the hypertext notion of links to time-based media and compositions of different media

    Abstract
    Considers whether an information system can be designed that is capable of meeting the needs of researchers students' for training and those of the general public for information. Tests a system for specialists to determine whether non specialist could use it and whether other uses could be found for such databanks. This multimedia information system based on natural language text searching uses hypertext, associating texts, images, maps and plans of the Greek site of Delphi. Discusses natural language searching, the respective and complementary contributions of automatic and manual indexing, image and document retrieval from other databanks and the different modalities of interactive searching. Defines the features of this type of information system and assesses the limits and the potential of such a product

    Abstract
    Describes the work of the Working Group 8 of ISO/IEC Joint Technical Committee 1 subcommittee 18 (JTC1/SC18/WG8) which is developing information technology standards for use in text and Office systems. In 1986 the Standard Generalized Markup Language (SGML) was introduced as one of the key standards in developing systems for open information interchange. In Nov 92 the Hypermedia/Time-based Structuring Language (HyTime) detailed in ISO 10744 was introduced for the interchange of multimedia and hypermedia. They are currently working on a Standard Multimedia Scripting Language (SMSL) which will enable system developers to interchange multimedia scripts, probably using the UK developed Architecture Neutral Distribution Format (ANDF)

    Abstract
    Develops an integrated conceptual representation scheme for multimedia documents that are viewed to comprise an object-oriented database. Develops the necessary abstractions for the conceptual model and extensions to the RM/T relational model used as the search structure. Develops a retrieval model in which the database search space is 1st narrowed down, based on user query, by an associative search. The associative search is followed by semantic and media-specific searches. A query langugae called SQLX is introduced to fomulate these searches directly from the conceptual model. In SQLX, connector attributes replace join, and abstract data type enables use of objects and their methods in query formulation. Describes a temporal model for time-dependent presentations and with the directions for future work

    Abstract
    Integrated multimedia systems process text, graphics, and other discrete media as well as digital audio, and video data. Considerable amounts of graphics, audio and video data in their uncompressed form, especially moving pictures, require storage and digital network capabilities that will not be available in the near future. Nevertheless, local, as well as networked, multimedia applications and systems have become realities. In order to cope with these storage and communication requirements in such integrated multimedia systems, compression technology is essential. This paper starts with a brief motivation of the need for compression and subsequently states the essential requirements for these techniques in the scope of multimedia systems and applications. As most of these techniques apply the same principles, namely, the source, entropy, and hybrid coding fundamentals, these are explained in detail. Based on a general framework of the steps encountered in a compression system - data preparation, processing, quantization, and entropy coding - this paper outlines details about the techniques developed by CCITT (H.261, i.e. px64), in the ISO/IEC (JPEG, MPEG) stadardization bodies and the proprietary DVI system

    Abstract
    Reports the basis for a cognitive walkthrough method to support the evaluation of multimedia presentations, e.g. 'how to do it' demonstrations. The walkthrough is founded upon an analysis of the cognitive processes and representations formed by the comprehension of the presentation. Issues include evaluation of attention, topic focus and information types. The walkthrough provides a series of guidelines for evaluation based on these cognitive models, such as the use of media, scripting and presentation techniques. The value of the guidelines is validated by several empirical studies. Reports an eye tracking study providing evidence as to how visual attention responds to multimedia materials. A series of comprehension studies then investigates the effectiveness of a presentation before and after the guidelines were applied. Illustrates with an example evaluation and studies of a commercially produced multimedia CD-ROM presentation on the etiology of cancer
