This paper presents a model for storage of remote Internet-based multimedia meetings and information retrieval from textual and time-based content. The model builds on a theory of content mapping that exploits temporal and contextual relationships between media streams. Two prototypes are presented which illustrate the application of the model to a virtual meeting environment, and to a system for visualisation of meeting records on mobile devices. Implications of the proposed content mapping model with respect to interface design and non-linear browsing of time-based media are also discussed.
