Claims16
A transmitter for processing a broadcasting signal, the transmitter comprising:
- a first encoder configured to Bose Chaudhri Hocquenghem (BCH) encode broadcasting data that is carried by a physical path and to Low Density Parity Check (LDPC) encode the BCH encoded broadcasting data;
- a second encoder configured to BCH encode signaling data and to LDPC encode the BCH encoded signaling data, wherein the LDPC encoded signaling data includes a group identifier field for identifying a group to which a current physical path belongs;
- a time interleaver configured to time interleave the LDPC encoded broadcasting data;
- a frame builder configured to assemble the time interleaved broadcasting data and the LDPC encoded signaling data to build a signal frame that includes at least one data slice that includes the time interleaved broadcasting data;
- and a modulator configured to transmit the broadcasting signal including the signal frame, wherein the signaling data includes bundled information indicating whether the physical path is bundled with another physical path within a broadcasting system;
- and data of the bundled physical path are de-multiplexed into multiple data slices.

A receiver for processing a broadcasting signal, the receiver comprising:
- a tuner configured to receive the broadcasting signal;
- a frame parser configured to parse a signal frame from the received broadcasting signal, wherein the signal frame includes at least one data slice and signaling data;
- a time deinterleaver configured to time deinterleave data in the at least one data slice, wherein the data is carried by at least one physical path;
- a first decoder configured to Low Density Parity Check (LDPC) decode the signaling data and to Bose Chaudhri Hocquenghem (BCH) decode the LDPC decoded signaling data, wherein the signaling) data includes a group identifier field for identifying a group to which a current physical path belongs;
