Towards a Distributed Quality of Service Handler for Multimedia Presentations

Abstract

Distributed multimedia presentation, involving different media objects on different servers, must strictly follow its defined temporal scenario. Out of synchronization is a fundamental problem in case of distributed multimedia. In this paper, we introduce a distributed QoS handler, whose aim is to distribute the QoS adaptation tasks among all the servers holding the media object. In this case, the client is considerably freed from the QoS-related tasks and it focuses only on playing the received, adapted media objects and notifying the end of their presentation to the concerned servers. This will lead to a better load balance for playing a distributed multimedia application, where the tasks of applying QoS rules and playing the objects are better distributed among the playing client and the media object servers.
