An end-user system (10) for transforming real-time streams of content into an output presentation includes an input device (30) that allows a user to interact with the streams in order to adapt the presentation. The input device (30) includes representation objects (340), each of which represents a specific stream of content, and a transmission object (300). In order to activate a particular stream of content, the user connects the corresponding representation object (340) to the transmission object (300). The user can deactivate the stream of content by removing the corresponding representation object (340) from the transmission object (300). The transmission object (300) determines which representation objects (340) have been connected to it, and indicates these connections to the end-user system (10), which activates and deactivates the streams, accordingly.
