Patent Images
1. A method of processing broadcast data in a broadcast transmitter, the method comprising:
- randomizing broadcast service data;
first encoding the randomized broadcast service data to add parity data;
second encoding the first-encoded broadcast service data at a code rate of D/E, wherein D<
E, and wherein D and E are integers equal to or greater than 1, respectively;
first interleaving the second-encoded broadcast service data;
encoding signaling data for signaling the broadcast service data;
modulating the first-interleaved broadcast service data and the encoded signaling data; and
transmitting the modulated data, wherein the signaling data include information for indicating the code rate.

Abstract
A broadcast transmitter and a method of processing broadcast data in the broadcast transmitter are disclosed. The method includes randomizing broadcast service data, first encoding the randomized broadcast service data to add parity data, second encoding the first-encoded broadcast service data at a code rate of D/E, first interleaving the second-encoded broadcast service data, encoding signaling data for signaling the broadcast service data, modulating the first-interleaved broadcast service data and the encoded signaling data, and transmitting the modulated data.
