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 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 that demodulates the channel symbols into codewords, and a decoder that decodes the 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. The demodulator and/or the decoder is configured to use the redundancy data for demodulation and decoding, respectively.

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 translation: 用于在广播系统中接收数据的接收机包括广播接收机，其通过广播系统接收包含由星座图中的星座点表示的多个信道符号的接收机输入数据流。 解调器将信道符号解调为码字，并且解码器将码字解码为输出数据字。 宽带接收机通过宽带系统获得冗余数据，用于包括信道符号的一个或多个最不健壮的比特的信道符号的冗余数据或指示包括表示信道符号的星座点的星座点的子集的星座子集标识符。 解调器和/或解码器被配置为使用冗余数据来解调相应的信道符号并且分别解码相应的码字。
