Abstract

A receiver includes: a broadcast receiver receiving a receiver input data stream segmented into frames, wherein basic codeword portions of codewords are mapped onto the frames, a codeword including at least a basic codeword portion generated from an input data word according to a first code; a data demapper demapping the basic codeword portions; a decoder error correction code decoding the codewords into output data words of at least one output data stream in a regular decoding using the basic codeword portion in a codeword; a check unit checking if the regular decoding of a codeword is erroneous; a unicast request unit requesting, if the regular decoding of a codeword is erroneous, an auxiliary codeword portion of the erroneously decoded codeword for incremental redundancy in an additional decoding; a unicast receiver unit receiving an auxiliary codeword portion of the erroneously decoded codeword.
