A simple rendering system for web presentation

We consider the problem of rendering a PC-projector oriented presentation to a web based one. For the maximum compatibility, the simplest way is to convert the original presentation into a sequence of images in a standard format (e.g. PNG) then perform a "slideshow" at the web sewer side. We further introduce techniques used in video compression to exploit the redundancy and to adapt for network heterogeneity. A simple Java apple1 based implementation is also shown.
