Broadcast transmitting apparatus and method for processing broadcast signals
First Claim
1. 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, andwherein 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.

Abstract
An apparatus and method for processing digital broadcast signal are provided. The method for processing a broadcast signal includes forming a data group having mobile broadcast service data, where forming the data group includes 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, and de-interleaving data of the data group having the mobile broadcast service data, known data sequences, signaling data and place holder bytes, and formatting mobile broadcast service data packets including the de-interleaved data of the data group, where formatting the mobile broadcast service data packets includes removing place holder bytes for the non-systematic RS parity, and replacing place holder bytes for the MPEG header with the MPEG header.

6. An apparatus for transmitting a broadcast signal, the apparatus comprising:
-
a group formatter configured to form a data group including mobile broadcast service data, wherein the group formatter is further configured to; map the mobile broadcast service data into corresponding locations of the data group; add known data sequences and signaling data into the data group; insert place holder bytes for MPEG header and non-systematic Reed-Solomon (RS) parity; and de-interleave data of the data group; a packet formatter configured to format mobile broadcast service data packets including a portion of the de-interleaved data of the data group, wherein the packet formatter is further configured to remove place holder bytes for the non-systematic RS parity in the data group in which data are deinterleaved; and replace place holder bytes for the MPEG header with the MPEG header in the data group in which data are deinterleaved; and a transmission unit configured to transmit 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. - View Dependent Claims (7, 8, 9, 10)
