Modeling and Analysis of Spatiotemporal Behavior of Multimedia in SMIL

Abstract

Along with the broadband technology matured, more and more information can be found in the Internet. Using multimedia resources to express content will be an invertible trend. How to efficient and fast integrate multimedia has been a hot research topic. In design of multimedia content, there are three important considerations such as allocation of presentation window, scheduling, and flowchart planning. The other important issue is to verify the designed multimedia plan. Due to each object has its specific feature, the spatial and temporal behavior among these objects easily cause interference during content playing. This paper will focus on temporal and spatial behavior of multimedia in SMIL. We proposed the Reachability Tree analysis methods to detect spatiotemporal interference in the designed multimedia. In this way, teacher can be reminded to exclude the interference in multimedia content.
