Abstract
A transmitter and transmission method for broadcasting data. To enable a receiver, such as a moving receiver, to improve decoding quality, if needed, a transmitter includes: a data input receiving at least one transmitter input data stream segmented into input data words; an encoder error correction code encoding the input data words into codewords including a basic codeword portion and an auxiliary codeword portion, the encoder generating the basic codeword portion from an input data word according to a first code and generating the auxiliary codeword portion from an input data word according to a second code, the basic codeword portion for regular decoding and the auxiliary codeword portion for incremental redundancy if regular decoding of the codeword by using the basic codeword portion is erroneous; a data mapper mapping the codewords onto frames of a transmitter output data stream; and a transmitter transmitting the transmitter output data stream.
