Abstract

A control device for use in a broadcast system includes a broadcast controller that controls a broadcast transmitter of the broadcast system that broadcasts broadcast signals in a coverage area for reception by terminals including a broadcast receiver and a broadband receiver, and a broadband controller that controls a broadband server of a broadband system that provides redundancy data to terminals within the coverage area. The broadband controller is configured to control the provision of redundancy data by the broadband server for use by one or more terminals which use the redundancy data together with broadcast signals received via said broadcast system for recovering content received within the broadcast signals and/or provided via the broadband system.
