Abstract

This paper centres on the tools for the management of new digital documents, which are not only textual, but also visual-video, audio or multimedia in the full sense. Among the aims is to demonstrate that operating within the terms of generic Information Retrieval through textual language only is limiting, and it is instead necessary to consider ampler criteria, such as those of MultiMedia Information Retrieval, according to which, every type of digital document can be analyzed and searched by the proper elements of language for its proper nature. MMIR is presented as the organic complex of the systems of Text Retrieval, Visual Retrieval, Video Retrieval, and Audio Retrieval, each of which has an approach to information management that handles the concrete textual, visual, audio, or video content of the documents directly, here defined as content-based. In conclusion, the limits of this content-based objective access to documents is underlined. The discrepancy known as the semantic gap is that which occurs between semantic-interpretive access and content-based access. Finally, the integration of these conceptions is explained, gathering and composing the merits and the advantages of each of the approaches and of the systems to access to information.

Abstract

Reviews the information systems methodologies that can be used to assist in the structuring of systems projects to create multimedia databases. Examines some of the options with a view to their supporting the design of user interfaces for public access systems. An initial exploration of the systems life cycle is followed by the key stages in any methodology. Describes a range of user centred methodologies, cooperative and participative methodologies and task oriented approaches to design. Introduces an object oriented methodology to the design of a multimedia graphic user interface

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

Discusses models for storing and presenting multimedia documents integrating large amounts of data of different types. Multimedia systems integrate a variety of data such as voice, graphics, text, video and other types of images into a single document. Most of these data are not structured and therefore require a huge storage capacity. Such a requirement causes many problems for traditional database management systems which were not originally designed to manipulate data other than text. Presents 2 data storage models and several other associated models for the presentation of multimedia documents. The analysis of these models reveals their capacity to synchronize various temporal scenarios while allowing users simultaneous and secure access to multimedia systems

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

Reviews the future possibilities of convergence of digital image storage and dissemination techniques, cable and high resolution television and networks such as the Internet, in bringing sophisticated multimedia information services into the home and businesses. Predicts the future of these systems in publishing, entertainment, education, health care, telephone systems, computer software use, and business and suggests that the ultimate converged system could provide homes and businesses with the means of sending and receiving information by facsimile transmission, making copies, and accessing information from CD-ROM and CD-I drives

Abstract

Presents a 3 facet adaptive authoring model for online hypermedia information systems. It provides spatial reconfiguration of the presentation objects based on activation frequency, information content customization based on author specified criteria, and hypergraphic network optimization based on usage. Discusses the theory underlying the model, its architecture and hypermedia structure, and provides a preliminary quantitative measure and evaluation of its impact on authoring time, as well as study time

Abstract

Reviews the particular qualities of the CD-ROM and the World Wide Web on the Internet in their separate operation, and then makes out a case for their combined use. The need for such hybrid systems results from problems of bandwidth across networks, and presumably these difficulties may be resolved as network speeds are upgraded. In the meantime hybrid CD-ROM/WWW applications have the potential to deliver the necessary bandwidth for multimedia combined with the timeliness of the Web. The author draws on experience within AGOCG (the Advisory Group Computer graphics: a JISC initiative)

Abstract

Film, videotape and multimedia archive systems must address the issues of editing, authoring and searching at the media (i.e. tape) or sub media (i.e. scene) level in addition to the traditional inventory management capabilities associated with the physical media. This paper describes a prototype of a database design for the storage, search and retrieval of multimedia and its related information. It also provides a process by which legacy data can be imported to this schema. The Continuous Media Index, or Comix system is the name of the prototype. An implementation of such a digital library solution incorporates multimedia objects, hierarchical relationships and timecode in addition to traditional attribute data. Present video and multimedia archive systems are easily migrated to this architecture. Comix was implemented for a videotape archiving system. It was written for, and implemented using IBM Digital Library version 1.0. A derivative of Comix is currently in development for customer specific applications. Principles of the Comix design as well as the importation methods are not specific to the underlying systems used.
