Patent ID: 8755774

Claim:
A method for processing a broadcast signal in a transmitter, the method comprising: forming a data group including mobile broadcast service data, wherein forming the data group comprises: mapping the mobile broadcast service data into corresponding locations of the data group; adding known data sequences and signaling data into the data group; inserting place holder bytes for MPEG header and non-systematic Reed-Solomon (RS) parity into the data group; and de-interleaving data of the data group; formatting mobile broadcast service data packets including a portion of the de-interleaved data of the data group, wherein formatting the mobile broadcast service data packets comprises: removing place holder bytes for the non-systematic RS parity in the data group in which data are de-interleaved; and replacing place holder bytes for the MPEG header with the MPEG header in the data group in which data are de-interleaved; and transmitting a broadcast signal including the formatted mobile broadcast service data packets, wherein the formed data group is divided into a plurality of regions, wherein the known data sequences are added in some regions among the plurality of regions within the data group, wherein the signaling data are located between two of the known data sequences, and wherein the signaling data includes a transmission parameter channel (TPC) including a parade identifier identifying a parade to which the data group belongs, the parade being a collection of data groups.
