Claim 0:
1. A system comprising:
an orthogonal frequency-division multiplexing (OFDM)-based transmitter for transmitting a first multiplex and a second multiplex of at least one broadcast information signal in a broadcast transmission mode via a transmission medium, the transmitter further comprising:
an input for receiving the first multiplex of at least one broadcast information signal and the second multiplex of at least one broadcast information signal;
an encoding unit further comprising:
a first sub-encoding unit for encoding a block of data of the first multiplex of at least one broadcast information signal and for generating a first encoded block of data; and
a second sub-encoding unit for encoding a block of data of the second multiplex of at least one broadcast information signal and for generating a second encoded block of data;

a multiplexer unit for incorporating the first encoded block of data and the second encoded block of data into a media broadcast subframe of a single broadcast transmission signal, wherein the encoded blocks of data of the first multiplex of at least one broadcast transmission signal and the second multiplex of at least one broadcast information signal are separately accessible and separately derivable;
a control signal generator unit for generating a first control signal Broadcast Information Message (BIM) incorporated in the single broadcast transmission signal, the first control signal BIM comprises a plurality of partial control signals wherein each of the plurality partial control signals refer to a position of one of the encoded blocks of data of the first multiplex and the second multiplex; and
an orthogonal frequency-division multiplexing (OFDM)-based receiver for receiving the single broadcast transmission signal in a broadcast reception mode, wherein the OFDM-based receiver contains:
an input for receiving the single broadcast transmission signal;
a demultiplexer unit for extracting the encoded block of data of the first multiplex and the encoded block of data of the second multiplex from the single broadcast transmission signal;
a decoding unit for decoding the encoded blocks of data for obtaining a block of data of the first multiplex of the at least one broadcast information signal, and for obtaining a block of data of the second multiplex of the at least one broadcast information signal; and
an output for outputting at least one broadcast information signal from the first multiplex, wherein the media broadcast subframe contains an encoded block of data of a second multiplex of at least one broadcast information signals, the demultiplexer unit being further configured to extract the encoded block of data of the second multiplex of the broadcast transmission signal, and the decoding unit being further configured to decode the encoded block of data of the second multiplex in a decoded block of data of the second multiplex.
