On-Demand Hypermedia/Mutimedia Service Using Pre-Orcestrated Scenarios Over The Internet

In this paper we present a unified approach for delivering hypermedia/multimedia
objects over broadband networks. The described service consists of several multimedia servers
and a set of functions that intend to present to the end user interactive information in real-time.
The hypermedia documents are structured using a hypermedia markup language that keeps information
of the spatiotemporal relationships among document’s media components. In order to
deal with the variant network behavior, buffering manipulation mechanisms and grading of the
transmitted media quality techniques are proposed to smooth presentation and synchronization
anomalies.
