The hybrid Java and XML-based MOBISERVE Rich Media middleware for DVB IP Datacast

In this paper, the MOBISERVE terminal application middleware is introduced. Firstly, two different approaches to describe rich media services on mobile terminals are characterized. These are the Java-based approach and the XML-based approach. In this context, the rich media concept encompasses the combined usage of synchronized dynamic and static content (e.g. audio/video, text, graphics) together with end user interactivity. Based on that, the MOBISERVE terminal platform with different middleware profiles is described. The middleware supports the combined (hybrid) usage of both Java-based and XML-based rich media elements in one service. As the applicability of the approaches differs from use case to use case, this paper characterizes typical XML-oriented respective Java-oriented use-cases. This is done based on the end user scenarios which were prepared within the MOBISERVE project.
