Synchronized and retrievable video/HTML lecture system for industry employee training

We present a web-based course system for teaching and training the industry employee. This system is designed to synchronize and retrieve the data related to HTML lecture notes and lecture video. The overall system consists of two frameworks, the Web-based Synchronized Multimedia Lecture (WSML) framework and the XML-Based Synchronized Hypermedia Video Query (XSHVQ) framework. The WSML system synchronizes the presentation of the streaming video lecture, the HTML-based lecture notes and the HTML Navigation Events. It also automates the recording of these three media events based on the Synchronized Multimedia Integration Language (SMIL) specification. To create an online course using this system, teachers first convert their lecture notes into the HTML pages and present the HTML-based lectures in a digital studio. Then the synchronized video clips and the associated HTML-based notes are deposited in our course database for on-demand self-paced learning. The XSHVQ system is designed to efficiently search for the desired video segments based on the synchronization information between video clips and the associated HTML-based notes. To query desired video segments using XSHVQ system, users simply use `keyword' search for the HTML lecture notes and the system can locate the corresponding video segments and present them to users.
