DIGITAL BROADCASTING SYSTEM AND DATA PROCESSING METHOD THEREOF

摘要

A digital broadcast receiver for receiving a transmission stream including a supplementary data stream and a normal data stream comprises a demodulator for demodulating a received transmission stream and an equalizer for equalizing the transmission stream. The transmission stream is received from a digital broadcast transmitter which constructs a transmission stream so that a predetermined packet in the supplementary data stream is positioned on a predetermined portion in a frame.
