The hypermedia documents are structured using a hypermedia markup language that keeps information of the spatiotemporal relationships among document’s media components.

Up to now most systems lack the ability to present the user with hypermedia information containing various media that have specific spatio-temporal relations. In this paper we propose and describe a model that can describe such kinds of hypermedia presentations. The core of the model is an HTML-like language that supports tags for the description of timing relations between the information objects that compose a hypermedia presentation.1 aBouras, Christos1 aKapoulas, Vaggelis1 aSpirakis, Paul1 aMoiras, D1 aOuzounis, V1 aTatakis, A uhttps://telematics.upatras.gr/telematics/publications/implementing-spatio-temporal-relations-hypermedia-presentations-using-html-language00538nas a2200133 4500008004100000245007800041210006900119260001700188100002100205700002300226700001900249700001500268856012100283 1997 eng d00aAn HTML like language supporting time-depended transmission of hypermedia0 aHTML like language supporting timedepended transmission of hyper c6 - 11 April1 aBouras, Christos1 aKapoulas, Vaggelis1 aSpirakis, Paul1 aTatakis, A uhttps://telematics.upatras.gr/telematics/publications/html-language-supporting-time-depended-transmission-hypermedia01871nas a2200193 4500008004100000245008800041210006900129260001100198300001300209520119000222100002101412700002301433700001901456700001501475700001501490700002001505700001501525856013701540 1997 eng d00aUsing Multimedia/Hypermedia Tools over Networks for Distance Education and Training0 aUsing MultimediaHypermedia Tools over Networks for Distance Educ cSummer a 20 - 263 aThe rapid developments in the Information Technology sector as well as the deployment of faster networks brings us to the era of the New Information Technology (NIT). The citizen of the near future must be able to use them else he will be seriously handicapped in his everyday life. Thus NIT becomes part of the educational process while on the other hand offers the tools and the infrastructure for the establishment of the distance education process. The educators are one of the first professions that must learn to use NIT and its tools. Multimedia/hypermedia tools offer solutions to the problems posed by the distance education process. They can be user-friendly and enticing and they can cover most, if not all, the needs of their users. A lot of prototype systems (tools) for distance education have been developed, each offering a number of functions that aid the process of distance education. The rapid growth of World Wide Web is adding another factor that can lead to the wider deployment of distance education systems. Although the value of distance education is unquestionable there is still a lot of work to be done before a wide spread implementation platform emerges.1 aBouras, Christos1 aKapoulas, Vaggelis1 aSpirakis, Paul1 aLampsas, P1 aTatakis, A1 aKontogiannis, S1 aFotakis, D uhttps://telematics.upatras.gr/telematics/publications/using-multimediahypermedia-tools-over-networks-distance-education-and-training00733nas a2200205 4500008004100000245008700041210006900128260001700197300001300214100002100227700002300248700001900271700001500290700001500305700001700320700001600337700001900353700002400372856013100396 1996 eng d00aFINE:Implementation of a Distributed Telematics Environment for Clinical Engineers0 aFINEImplementation of a Distributed Telematics Environment for C c10 -12 April a 56 - 601 aBouras, Christos1 aKapoulas, Vaggelis1 aSpirakis, Paul1 aTatakis, A1 aFotakis, D1 aBalaouras, P1 aChadelis, L1 aPalikarakis, N1 aSandalatzopoulos, R uhttps://telematics.upatras.gr/telematics/publications/fineimplementation-distributed-telematics-environment-clinical-engineers01365nas a2200205 4500008004100000245007900041210007500120260001700195300001300212520061800225100002100843700002300864700001900887700001500906700001500921700002000936700001500956700001600971856017200987 1996 eng d00aAn Interactive Cooperative Teleworking Environment-Tηλεµάθεια ∗0 aInteractive Cooperative Teleworking EnvironmentTηλεµάθεια ∗ c17 - 22 June a 37 - 423 a
In this paper we present the design and the implementation of an interactive environment for cooperative teleworking. Telemathea offers tools that support the communication and the teleworking between tutor and trainee, who may reside in remote geographical regions. This environment offers audio communication over the network as well as support for joint editing of text documents and still images. It supports different audio coding techniques so as to adjust to the available bandwidth, and makes use of the RTP protocol in order to facilitate the exchange of audio and, in the future, video packets.

Documents are stored in various multimedia servers, while the inline data may reside in their own media servers, attached to the multimedia servers. The described service consists of several multimedia servers and a set of functions that intend to present to the end user interactive information in real-time. Users interact with the service requesting multimedia docu- ments on demand. Various media streams are trans- mitted over dierent parallel connections according to their transmission requirements. The hypermedia doc- uments are structured using a hypermedia markup lan- guage that keeps information of the spatiotemporal re- lationships among document's media components. In order to deal with the variant network behavior, buering manipulation mechanisms and grading of the transmitted media quality techniques are proposed to smooth presentation and synchronization anomalies.1 aBouras, Christos1 aKapoulas, Vaggelis1 aSpirakis, Paul1 aMoiras, D1 aOuzounis, V1 aTatakis, A uhttps://telematics.upatras.gr/telematics/publications/demand-hypermediamultimedia-service-over-broadband-networks01735nas a2200193 4500008004100000245005800041210005700099260001700156300001500173520111800188100002101306700002301327700001901350700001501369700001501384700001501399700002201414856010501436 1995 eng d00aHIPPOCRATES: A multimedia tool for distance education0 aHIPPOCRATES A multimedia tool for distance education c17 - 21 June a 103 - 1083 aIn this paper we present a software tool for the realisation of the distance education service, that is the conduction of classes through the use of computers. The classes are directed towards personnel in various areas and aim at the retraining and update of the personnel in subjects of special interest in their line of work. The conduction of classes takes place, from and towards, remote regions with the aid of a computer network. Hippocrates is a flexible and easy-to-use application, which permits students, who sit in front of remotely situated workstations, to attend classes or seminars given by a teacher or expert, who can also be located in some remote geographical area. Hippocrates can be thought of as a distributed transparency projector. The teacher can project transparencies on the screens of the students’ workstations and can emphasize or indicate regions of interest on them by using the graphical tools offered by Hippocrates. Immediate results of the use of Hippocrates are the fast updating of the personnel in remote areas and the upgrading of the quality of the services they offer.1 aBouras, Christos1 aKapoulas, Vaggelis1 aSpirakis, Paul1 aLampsas, P1 aTatakis, A1 aFotakis, D1 aPapoutsopoulos, G uhttps://telematics.upatras.gr/telematics/publications/hippocrates-multimedia-tool-distance-education00970nas a2200193 4500008004100000245005300041210005300094260002800147300001500175520035400190100002100544700002300565700001900588700001500607700001500622700002000637700001500657856010400672 1995 eng d00aMultilingual Implementations of OSI Applications0 aMultilingual Implementations of OSI Applications c30 October - 1 November a 367 - 3743 aIn this work the problem of supporting multilingual environments over OSI applications is addressed.
