Abstract
An apparatus and method demapping a demapping input data stream having a channel bandwidth received in a multi-carrier broadcast system into a demapping output data stream. A stream demapping mechanism demaps second frames from the demapping input data stream, and a frame demapping mechanism demaps the second frames including a preamble portion and a payload portion into the demapping output data stream. The frame demapping mechanism demaps signalling data from the preamble portion, which includes at least one preamble symbol carrying at least one preamble signalling block including signalling data, and demaps data blocks of the demapping output data stream from the payload portion by using signalling information. Payload data are mapped onto the payload portion including plural data symbols carrying payload data of at least two mapping input data streams, the payload portion being segmented into data segments each covering a bandwidth portion of the channel bandwidth.
