Book Description
LES TRAVAUX DE CETTE RECHERCHE SE SITUENT DANS LE DOMAINE DE LA GESTION INFORMATIQUE D'INFORMATIONS OBJECTIVES BRUITEES PAR DES DIMENSIONS SUBJECTIVES. CES INFORMATIONS BRUITEES EXISTENT MAJORITAIREMENT DANS LE MONDE REEL ESSENTIELLEMENT MULTIMEDIA MAIS LES INFORMATICIENS LES IGNORENT HABITUELLEMENT POUR NE S'INTERESSER QU'A LA MODELISATION DES DIMENSIONS OBJECTIVES. APRES UNE ANALYSE DE L'EVOLUTION DES DONNEES DU MONDE REEL TRAITEES PAR LES OUTILS INFORMATIQUES, NOUS NOUS ATTACHONS A LA PROBLEMATIQUE DU TRANSFERT DE CONNAISSANCES DE LA MACHINE A L'HOMME. NOUS PROPOSONS TOUT D'ABORD UNE MODELISATION ET UN FORMALISME PERMETTANT LA GESTION DE CES DONNEES PAR SIMULATION MULTIMEDIA INTERACTIVE ET UNE METHODE DE CONCEPTION D'UN SYSTEME D'INFORMATION DEDIE A LA COMMUNICATION HUMAINE ENTRE DES POPULATIONS QUI N'ONT PAS LES MEMES REFERENCES COGNITIVES. DES CONCEPTS CLEFS SONT PROPOSES: 1. LES COUCHES D'ACCES AUX CONNAISSANCES OBJECTIVES ET PARTAGEABLES SOCIALEMENT ; 2. L'OBJET PIVOT DE CONNAISSANCES ; 3. LA POSSIBILITE DE TRAITER EN PARALLELE DES CONTENUS SEMANTIQUES SUR LES DIFFERENTS MEDIAS. NOUS DECRIVONS ENSUITE UN SYSTEME INFORMATIQUE COMPORTANT DEUX VOLETS: UNE SIMULATION MULTIMEDIA INTERACTIVE QUI PREND EN CHARGE LES PARAMETRES BRUITANT LES INFORMATIONS OBJECTIVES, ET UN MODULE DE PILOTAGE PAR UN SYSTEME DE PILOTAGE MULTI-AGENTS HYBRIDE PRENANT EN COMPTE LES RESULTATS DE LA SIMULATION ANALYSES PAR RESEAU NEUROMIMETIQUE. ENFIN, NOUS DECRIVONS LA METHODE DE MISE EN CORRESPONDANCE DE CONTENUS OBJECTIFS ET SUBJECTIFS DE CONNAISSANCE ET DES TECHNOLOGIES MULTIMEDIA. LE PROTOTYPE D'UN SYSTEME, DEDIE A LA REEDUCATION DE LA MEMOIRE DE CEREBRO-LESES, A PU ETRE CONCU PAR CETTE METHODE ; LES RESULTATS DE SA PRE-VALIDATION EN SITUATION REELLE EN DONNENT UNE ILLUSTRATION

Book Description
Multimedia computing has emerged in the last few years as a major area of research. Multimedia computer systems have opened a wide range of applications by combining a variety of information sources, such as voice, graphics, animation, images, audio and full-motion video. Looking at the big picture, multimedia can be viewed as the merging of three industries: computer, communications, and broadcasting industries. Research and development efforts can be divided into two areas. As the first area of research, much effort has been centered on the stand-alone multimedia workstation and associated software systems and tools, such as music composition, computer-aided education and training, and interactive video. However, the combination of multimedia computing with distributed systems offers even greater potential. New applications based on distributed multimedia systems include multimedia information systems, collaborative and video conferencing systems, on-demand multimedia services, and distance learning. Multimedia Systems and Techniques is one of two volumes published by Kluwer, both of which provide a broad introduction into this fast moving area. The book covers fundamental concepts and techniques used in multimedia systems. The topics include multimedia objects and related models, multimedia compression techniques and standards, multimedia interfaces, multimedia storage techniques, multimedia communication and networking, multimedia synchronization techniques, multimedia information systems, scheduling in multimedia systems, and video indexing and retrieval techniques. Multimedia Systems and Techniques, together with its companion volume, Multimedia Tools and Applications, is intended for anyone involved in multimedia system design and applications and can be used as a textbook for advanced courses on multimedia.

Book Description
Multimedia Systems discusses the basic characteristics of multimedia operating systems, networking and communication, and multimedia middleware systems. The overall goal of the book is to provide a broad understanding of multimedia systems and applications in an integrated manner: a multimedia application and its user interface must be developed in an integrated fashion with underlying multimedia middleware, operating systems, networks, security, and multimedia devices. Fundamental characteristics of multimedia operating and distributed communication systems are presented, especially scheduling algorithms and other OS supporting approaches for multimedia applications with soft-real-time deadlines, multimedia file systems and servers with their decision algorithms for data placement, scheduling and buffer management, multimedia communication, transport, and streaming protocols, services with their error control, congestion control and other Quality of Service aware and adaptive algorithms, synchronization services with their skew control methods, and group communication with their group coordinating algorithms and other distributed services.

Book Description
The uses of multimedia are rapidly increasing. Its power to present information in ways not previously possible and its integration of resources, allow for the creation of rich learning environments. Perspectives on Multimedia: Communication, Media and Information Technology provides a critical examination of the latest multimedia developments and approaches, such as Interface Technology and QoS architectures. Topics covered include: The key concepts intrinsic to digital forms of multimedia: integration, interactivity, hypermedia, immersion, narrativity and hybridity. The development of Information Technology (IT) usage in society and in the business community. How modern IT enables private companies and public organisations to support business operations, create new business opportunities, and to promote more proactive service management. Multimedia from a computer science perspective and how computer science provides the technical foundation for the computer software and hardware that drives the information age. Gives a broad range of perspectives on key issues for interactive multimedia in organisations and industry today. This book will be of interest to practitioners involved in multimedia development in an organisation, management consultants giving professional advice on digital solutions and information technology matters to their customer organisations and academics focusing on business and technical aspects of multimedia frameworks.

Book Description
Multimedia information systems is a rapidly growing area of research and development, attracting increasing interest from a variety of application fields including business, entertainment, manufacturing, education, CAD, CAE, medicine, etc. Due to the diverse nature of the information dealt with and the increased functionality (e.g., user interaction), the capabilities and system requirements of multimedia information systems dramatically exceed those of conventional databases and database management systems. This book presents an integrated approach to interactive multimedia documents. After summarizing the prerequisites and background information, the author develops an IMD model taking into account interaction and spatiotemporal composition. Based on this model, the author develops an integrated framework covering most of the steps during the life cycle of an IMD, namely data modeling, authoring, verification and querying, execution and rendering, and indexing.
