DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA
First Claim
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;
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 digital receiving system, and a method of processing data are disclosed. The digital receiving system includes a receiving unit, a known sequence detector, and a channel equalizer. The receiving unit receives a broadcast signal including mobile service data and main service data. The known sequence detector detects known data linearly inserted in a data group. The channel equalizer performs channel-equalizing on the received mobile service data using the detected known data.
