Robust synchronization models for Presentation System using SMIL-driven approach

Current common Presentation System (PS) models are slide based oriented and lack synchronization
analysis either with temporal or spatial constraints. Such models, in fact, tend to lead to synchronization
problems, particularly on parallel synchronization with spatial constraints between multimedia element
presentations. However, parallel synchronization can be properly applied in non-slide based presentation
rather than in slide based. This paper presents a novel model of SMIL-driven PS which is able to
perform both slide and non-slide based presentations. This novel model of PS has been developed based
on the characteristics derived from the unification of characteristics of common PS models and SMIL
specifications. By such concept makes the PS has synchronization models i.e. parallel and sequential
synchronization with temporal and spatial constraints. Also it has ability to separate between presenter’s
and audiences’ views. Thus, to prove and to evaluate our SMIL-driven PS model, we applied the new PS in
real world using scenario based approach. Finally, we have a PS that is able to perform both hybrid slide
and non-slide based presentation since it has robust synchronization models that support temporal and
spatial constraints.
