Predictability and Resource Management in Distributed Multimedia Presentations

The continuous media applications have an implied temporal dimension, i.e. they are presented at a particular rate for a particular length of time and if the required rate of presentation is not met the integrity of these media is destroyed. We present a set of language constructs suitable for the de nition of the required QoS and a new real-time environment that provides low-level support to these constructs. The emphasis of the proposed strategy is given on deterministic guarantees and can be considered as a next step for the design and the implementation of predictable continuous media applications over a network.
