A Synchronization Model for Hypermedia Documents Navigation
A. Celentano and O. Gaggi
Abstract
This paper presents a model for describing the synchronization
between several media delivered over a network in a Web-based
environment. Synchronization concerns the download and the
activation of coordinated media files according to the structure
of the whole hypermedia document, the playback status of the media
objects, and the user interaction. The model defines five
synchronization primitives some of which can be automatically
deducted from the document structure and the media-related events.
The model is oriented to describe applications based on a main
video or audio narration to which static or dynamic documents are
attached. The model is suited for applications like distance
education, professional training, Web advertising and selling, and
news-on-demand.
