scenarios, seems to have several difficulties
due to presentation deadlines that should be satisfied, and
network’s unpredictable behavior which may lead to synchronization
anomalies among related media streams. Beyond
these, a structural model that represents such scenarios
is required. In this paper, we present a general framework
that addresses the above mentioned issues, and we
attempt to describe a unified approach for delivering hypermedia/
multimedia objects over network connections
preserving their timing constraints. We mainly concentrate
on the study and development of a markup language that
models the presentational structure of a multimedia object
and provides primitives that assure playout synchronization
of the different media streams that compose these
hypermedia objects. Methods for keeping a constant quality
level of presentation in times of network load are discussed.1 aBouras, Christos1 aKapoulas, Vaggelis1 aMoiras, D1 aOuzounis, V  uhttp://telematics.upatras.gr/telematics/publications/framework-distributed-information-service-using-hypermediamultimedia-pre-orchestrated?language=el
