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.

Abstract: A coding and modulation apparatus and method are presented. The apparatus comprises an encoder that encodes input data into cell words, and a modulator that modulates said cell words into constellation values of a non-uniform constellation. The modulator is configured to use, based on the total number M of constellation points of the constellation and the code rate, a non-uniform constellation from one or several groups of constellations each comprising one or more constellations.

Abstract: A receiver for receiving data in a broadcast system comprises a broadcast receiver that receives via said broadcast system a receiver input data stream comprising a plurality of channel symbols represented by constellation points in a constellation diagram, a demodulator that demodulates said channel symbols into codewords, and a decoder that decodes said codewords into output data words. A redundancy calculator determines a required amount of redundancy data required for correct demodulation and decoding by use of the originally received channel symbol and additional redundancy data. A broadband request unit requests, if demodulation of a channel symbol and/or decoding of a codeword is erroneous or likely to fail, a required amount of redundancy data via a broadband system, that is received by a broadband receiver via said broadband system. Said demodulator and/or said decoder is configured to use said redundancy data for demodulation and decoding, respectively.
