IPML: Structuring distributed multimedia presentations in ambient intelligent environments

This paper addresses issues of distributing multimedia presentations in an ambient intelligent environment, examines the existing technologies and proposes IPML, a markup language that extends SMIL for distributed settings. It uses a metaphor of play, with which the timing and mapping issues in distributed presentations are covered in a natural way. A generic architecture for playback systems is also presented, which covers the timing and mapping issues of presenting an IPML script in heterogeneous ambient intelligent environments.
