Deadline-driven packet scheduling policies provide highly flexible methods for real-time communication support of distributed multimedia applications. This paper presents a probabilistic approach for analyzing admission control and communication establishment for the general class of non-preemptive deadline-oriented packet scheduling policies. The prediction method can be used for communication and scheduling policy evaluation, routing for multimedia traffic and capacity planning. A large-scale simulation study demonstrates that our method provides highly accurate predictions of acceptance rates for multiple types of multimedia connection requests.

This paper presents the development of the SAMM integrated environment (Multimedia Presentation System), which has been proposed to support synchronized real-time communication and presentation of pre-orchestrated multimedia data. The employed multimedia synchronization technique was based on the eXtended model of the Object Composition Petri-Net (XOCPN). The integrated environment is presented by the description of its main components: the multimedia synchronization service; the modules that automate processes concerning the synchronization mechanism; and the Composition graphical application that works as a specialized authoring tool and helps users that want to compose multimedia presentations.

We present an implementation of Web based multicast audio and video application over QoS enabled networks. In order to apply QoS guaranteed multicast audio and video to the Web, architecture extension for real-time stream transmission, session directory service and QoS delivery embedded into the Web is needed. We attempt to identify a solution that can be deployed immediately. We design and implement a QoS based multicast multimedia application by integrating the RTP, SDP/SAP and RSVP into the Web, which allows Web users to join a multicast session and receive QoS guaranteed multicast audio and video seamlessly.

We propose a layered model for hypermedia document systems and use this model in the design and implementation of a prototype hypermedia document system. The model consists of three layers: a runtime layer (RTL) a document description layer (DOCDL) and a storage layer (SRL). The DOCDL contributes to defining the logical structure. It not only constrains the structure of the SRL, but also forms a bridge between the RTL and the SRL. In the DOCDL, an extended open document architecture (ODA) is employed for describing the logical structure of the document. In addition, we present a technique for automatically generating and updating database schema given a document logical structure. For the RTL, the document logical structure is visualized to help users to retrieve information, and as a means for multimedia data capture. The advantages and benefits of this approach are to allow the design and implementation of hypermedia systems to be automated and much simplified. The approach also caters for the continuous updating of the document logical structure such as adding an extra data object. The paper applies the proposed model to the design and implementation of a multimedia document system for medical documents.

Advances in networking and transmission of digital multimedia data will soon bring huge catalogues of music to users. Accessing these catalogues raises a problem for users and content providers, that we define as the music selection problem. We introduce three main goals to be satisfied in music selection: match user preferences, provide users with new music, and exploit the catalogue in an optimal fashion. We propose a novel approach to music selection, based on computing coherent sequences of music titles, and show that this amounts to solving a combinatorial pattern generation problem. We propose constraint satisfaction techniques to solve it. The resulting system is an enabling technology to build better music delivery services.

This paper describes a design that implements a Virtual Museum for its access through Internet. It can not only provide the information so far available in the Web, but also allows a three-dimensional (3D) walk through the whole Museum, watching its collections, plus a presentation of single objects in 3D, with different resolutions according to each visitor interests and with a real possibility of visitor-object interaction. All this opens a wide new path of investigation, as it brings 3D into Internet and means a contribution to the increase of interactivity in Web pages.

Conferencing applications require an efficient conference control service. This paper introduces the main features of a conference control service based on the CORBA event service using the Java platform, under development at the Communications and Telematic Services Group of the University of Coimbra. This framework is based on the ITU T.120 recommendations, with reliable multicasting communication for both data and control information. The control service extends the CORBA Event Service architecture with mechanisms for reliable IP multicast communication, with total ordering of the events transmission, filtering and fragmenting/reassembling of large messages.

European R&D programmes in telecommunication and information technology, managed by the European Commission Services, are about to start a new phase. The Information Society Technologies programme brings to the foreground the concept of convergence. Convergence between technologies but also between technology and the commercial and regulatory requirements to enable open global markets. The former industrial pre-competitive European R&D programmes, RACE (Research and Development in Advanced Communications in Europe) and ACTS (Advanced Communications Technologies and Services), maintained a strong symbiotic relationship with standardisation. Through mechanisms put in place during the lifetime of the programme the various research projects were clustered in concertation groups to harmonise approaches leading to clear and stronger contributions in the different standardisation organisation/consortia. The expectations are that standardisation in the networked multimedia domain works as enabler of market openness and fairness, public interest and social-cultural awareness (in the sense of taking into account the end-user as an individual or community) leading to a non-obstructive competitive attitude. This paper lists a non-exhaustive set of points in telecommunication and information technology where we believe R&D and standardisation must find a sustained input/output flow of background technological work and consensus-building mechanisms to achieve the above mentioned objectives.
