Abstract
Real time delivery of multimedia objects based on preorchestrated
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.
