Patent ID: 8787497

Claim:
A transmitter for transmitting broadcasting data to a receiver, the transmitter comprising: a first processor configured to process Layer 1 signaling data for signaling service data; and a second processor configured to process the service data, wherein the first processor comprises: a first BCH encoder configured to BCH encode the Layer 1 signaling data; a first low-density parity-check (LDPC) encoder configured to LDPC encode the BCH-encoded Layer 1 signaling data to generate at least one LDPC parity bit; a puncturing element configured to perform puncturing on the generated at least one LDPC parity bit; a first bit interleaver configured to bit interleave the LDPC-encoded Layer 1 signaling data and the punctured at least one LDPC parity bit; a first demultiplexer configured to demultiplex the bit-interleaved Layer 1 signaling data into cell words; and a first QAM mapper configured to map the cell words into constellation values of the L 1 signaling data, wherein the second processor comprises: a second BCH encoder configured to BCH encode the service data to generate an error protected data; a second LDPC encoder configured to LDPC encode the BCH-encoded service data; a second bit interleaver configured to bit interleave the LDPC-encoded service data; a second demultiplexer configured to demultiplex the bit-interleaved service data into cell words; and a second QAM mapper configured to map the cell words into constellation values of the service data, and wherein the Layer 1 signaling data have Program Specific Information (PSI) and Service Information (SI) reprocessing information for each physical path carrying the service data, the PSI/SI reprocessing information indicating whether a PSI/SI reprocessing has been performed.
