Abstract: A dynamic broadcast system as well as a terminal and a control device for use in such a dynamic broadcast system are presented. Transmission parameters, transmission times and transmission paths used for broadcasting and providing content, either via a broadcast network or a broadband network to terminals used in the dynamic broadcast system are dynamically controlled. Further, a decision logic is provided that dynamically decides transmission parameters, transmission times and transmission paths used for broadcasting and providing content based on monitoring data carrying information on user specific content usage and/or transmission quality data carrying information on the quality of a transmission link between a broadband server and a terminal and/or of a reception of content broadcast by a broadcast transmitter.

Abstract: A receiver for receiving data in a broadcast system includes a broadcast receiver that receives, via the broadcast system, a receiver input data stream including plural channel symbols represented by constellation points in a constellation diagram. A demodulator demodulates the channel symbols into codewords and a decoder decodes the codewords into output data words. A broadband receiver obtains redundancy data via a broadband system, the redundancy data for a channel symbol including one or more least robust bits of the channel symbol or a constellation subset identifier indicating a subset of constellation points including the constellation point representing the channel symbol. The demodulator and/or the decoder is configured to use the redundancy data to demodulate the respective channel symbol and to decode the respective codeword, respectively.

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.

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 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.
