Abstract
A transmitter and method of processing broadcast data are discussed. In one embodiment, the method includes Forward Error Correction (FEC) encoding Physical Layer Pipe (PLP) data at a first code rate; FEC encoding first signaling data at a second code rate; FEC encoding second signaling data at a third code rate; time interleaving the FEC-encoded PLP data; frequency interleaving the time-interleaved PLP data by a pair of consecutive cells; and modulating the frequency-interleaved PLP data, the FEC-encoded first signaling data, and the FEC-encoded second signaling data by an Orthogonal Frequency Division Multiplexing (OFDM) method, wherein the first signaling data include FEC type information of the second signaling data and wherein the second signaling data include FEC type information and the first code rate used by the PLP data.
