Multimedia systems and real-time systems : some analogies and similarities

Colloque avec actes et comité de lecture. internationale.International audienceReal-time systems and Multimedia systems have been developed separately for along time. The vocabularies are different, but some concepts are similar and it seems now useful to analuse and compare these systems in order to define more generic or common solutions and understanding. The applications characteristics, the operating system mechanisms and the modelling techniques are analysed for both of these systems

Specifying QoS for Multimedia Communications within Distributed Programming Environments

Because of the increasing emphasis on distributed object programming for the provision of multimedia telecommunications services, it has become apparent that a unification between the distributed programming environment and techniques for QoS specification in multimedia communications must be made. Various QoS frameworks and QoS reference models have already been established and/or standardised. Each has approached the problem of QoS specification in its own way but it is possible to draw similarities across the board. This paper examines four different approaches to QoS specification and attempts to integrate these ideas into the distributed programming environment (DPE)
