In this paper, we demonstrate the adaptation of multimedia digital radio services in broadcast environments based on scalable multimedia documents. The authoring of our multimedia services relies on the Scalable MSTI model that decomposes multimedia documents into three ordered dimensions: Spatial, Temporal and Interactive descriptions. Our demonstration shows Scalable MSTI multimedia documents that can be adapted to typical T-DMB digital radio usage scenarios.
