In this paper, we present the design of a flexible framework for an IP-based network that will support an interactive multimedia (MM) system. The system will enable end users to: 1) author their own MM presentations; 2) control the delivery of the presentation; and 3) interact with the content (media objects) to make changes to the presentation in real time. To facilitate the design of the system we have introduced the concept of a meta object and have defined three levels of user interactivity: presentation level interactivity; session level interactivity; and local level interactivity.
