Multimedia document browsing is a mean to improve information access and decision-making processes. However, multimedia data processing is resource consuming. The overload and the heterogeneity of processed data turn the consultation of multimedia documents into a difficult task. In this paper, we present the object-oriented design of an adaptable user interface improving the visualisation of temporal multimedia documents. We propose an approach that can be implemented on top of any legacy data-based or document-based systems. Our application is based on an inter-applications data interchange and on a generic time scale artefact for time events differentiation. We implemented a prototype of our solution in the domain of clinical decision support systems where documents are for instance medical reports or medical examination results (video, pictures, text, etc.). Our approach is generic enough to handle interoperability applications with any type of time-based multimedia document or data.
