Research Abstract	Two dimensional retrieval model for searching semantically synchronized media streams has been proposed. The effectiveness of this theoretically-based model has also been verified through rigorous experiments. Conventional IR systems, which support partial retrieval of synchronized media streams, retrieve "atomic units", for example slides, pages and shots of underlying media streams such as presentations, electronic books, and lecture videos respectively. In contrast, this model is based upon the concept of an extended retrieval unit and thus retrieves dynamically integrated media streams comprising several atomic units both along and across media streams. The model outperforms (a) conventional systems based on atomic retrieval units, (b) single dimensional retrieval systems, which extend retrieval units over several atomic units of the same media and (c) cross-media retrieval systems, which extend atomic retrieval units across several media stream units.
