Claim:
1. A method of processing broadcast data in a transmitter, the method comprising: Forward Error Correction (FEC) encoding Physical Layer Pipe (PLP) data of Physical Layer Pipes (PLPs); FEC encoding first signaling data; FEC encoding second signaling data; time interleaving the FEC-encoded PLP data; frequency interleaving the time-interleaved PLP data; 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 of the PLP data, wherein the second signaling data further includes Multi-Input Multi-Output (MIMO) information and modulation information for PLPs, wherein the modulation information represents a spectrum efficiency for two antennas when the MIMO information represents the MIMO processing is applied to the PLP data, and wherein a specific PLP among the PLPs includes bootstrap information and Electronic Service Guide (ESG) signaling information, wherein mapping information between the PLPs and IP address/ports is further included in the specific PLP, and wherein the second signaling data further includes information indicating whether a PLP is the specific PLP including the bootstrap information, the ESG signaling information and the mapping information.
