During the last two years, Purdue University’s Computer Graphics Technology department has been developing an open-architecture distance learning system capable of both synchronous and asynchronous instructional delivery. The system strives to provide the ability to deliver any instructional content, to any learner, under any condition through the integration of intelligent modules that dynamically determine the most appropriate mode of presentation for any particular learner. This paper details the development of a module for Purdue’s Unified Multimedia Delivery System capable of intelligently identifying and delivering asynchronous video content to users on traditional PC’s or PDA’s over a wireless environment. This provides the system with the capability to deliver traditional video- based instructional and supportive documentation such as schematics, illustration, and animation to students outside of the confines of their traditional classroom or laboratory. While many commercial solutions address the delivery of training materials using Internet technology, a commercial turnkey solution for delivering streaming video content over a wireless IP network does not currently exist in the distance learning market. Technologically, the system is built around Microsoft’s Active Server Pages and Windows Media Services. ASP s used to implement the logic and WMS provides the video streaming capabilities. The system also addresses on-site video delivery through the integration of a intelligent mechanism capable of identifying users accessing the module from wireless PDA’s and delivering alternate content through IEEE 802.11b Wireless LAN. Additionally, the system utilizes path- finding methodology and artificial intelligence algorithms to intelligently select the delivered instructional, user-specific content.
