«Quality of Service» Approach in Distributed Multimedia Systems

Abstract

Multimedia applications manage great quantities of data. These data must be managed while respecting temporal constraints in order to allow “to play” the video packages in a fluid way. If the temporal constraints are not respected, then the quality of service (QoS) provided to the users decreases. Our work in this paper consists in exploiting a QoS approach used in real-time database systems and applying it to multimedia systems. To this purpose, we present an architecture for the management of QdS in distributed multimedia systems, where the frames scheduling is controlled by a feedback loop.
