A Framework for Creating and Playing Distributed
Multimedia Information Systems with QoS Requirements

The design of services to support continuous media differs significantly
from that of services to support only traditional textual data.
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
definition of the required QoS and the real-time dimension of the media
that participate in a multimedia application.
We study also new methods that provide low-level support to these
language constructs and supply at runtime the required level of QoS
requirements to a set of distributed multimedia applications.
