Abstract: A media content distribution system (10) comprises a plurality of interconnected system resources (13-15) arranged to receive and/or transmit media content. A number of the system resources (13-15) have a capability of performing a transform processing operation on the media content. A system controller (20) automatically determines connectivity of the system resources (13-15) and determines the transform capabilities of the system resources using control messages received from the system resources. A first of the system resources can advertise information about a potential combined system resource which is possible if at least one transform capability of the first system resource is combined with at least one transform capability of another system resource. The system controller (20) can output a map of the system resources on the user interface (25). The user interface (25) can allow a user to explore detail of resources (13-15) and select routes between nodes.
