Abstract:
1. A method of processing broadcast data in a broadcast transmitter, the method comprising: encoding first enhanced data being input through a first path at a first code rate; encoding second enhanced data being input through a second path at a second code rate; first interleaving the encoded first enhanced data; first interleaving the encoded second enhanced data; converting the first-interleaved first enhanced data into symbol units; converting the first-interleaved second enhanced data into symbol units; second interleaving the converted first enhanced data; second interleaving the converted second enhanced data; encoding signaling information by using a coding scheme with a specific code, wherein the encoded signaling information is padded with zero-padding bits; forming a frame including the second-interleaved first enhanced data, the second-interleaved second enhanced data, and the encoded signaling information; and modulating data of the frame; and transmitting the modulated data of the frame, wherein the frame is composed of a first region and a second region, wherein the first region includes the signaling information and the signaling information includes information related to the first code rate and the second code rate, wherein the second region includes the second-interleaved first enhanced data and the second-interleaved second enhanced data, and wherein the first region is positioned in front of the second region.
