1. A transmitter for transmitting broadcasting data to a receiver, the transmitter comprising:
an LDPC (Low-density parity-check) encoder configured to LDPC encode Layer 1 signaling data to generate LDPC parity bits; a puncturer configured to perform puncturing on the generated LDPC parity bits; an interleaver configured to interleave the encoded Layer 1 signaling data on which the puncturing was performed; a QAM (Quadrature Amplitude Modulation) mapper configured to map the interleaved encoded Layer 1 signaling data to Layer 1 signaling data symbols; a frequency interleaver configured to frequency interleave the mapped Layer 1 signaling data symbols; and a transmission unit configured to transmit a signal frame including the frequency-interleaved Layer 1 signaling data symbols, wherein the signal frame further includes PLP (Physical Layer Pipe) data symbols of a PLP carrying one or more services, wherein the PLP data symbols in the signal frame are located after the Layer 1 signaling data symbols for signaling the PLP, wherein the Layer 1 signaling data include information for indicating a change of the Layer 1 signaling data. |
