Abstract:
1. A transmitter for transmitting at least one broadcasting signal having PLP (Physical Layer Pipe) data to a receiver, the transmitter comprising: an LDPC FEC Encoder configured to LDPC encode the PLP data and output FECFrame; a mapper configured to convert the FECFrame to XFECFrame by QAM constellation; a FEC-Frame-Header-Insertion configured to insert FECFrame header in front of the XFECFrame; a data slice builder configured to output at least one data slice based on the XFECFrame and the FECFrame header; a time-interleaver configured to perform time-interleaving at a level of the at least one data slice; a frequency-interleaver configured to frequency-interleave the time-interleaved at least one data slice; and a frame builder configured to build a signal frame based on the frequency-interleaved at least one data slice and preamble symbols having Layer-1 (L1) signaling information for signaling the at least one data slice.
