Broadcast receiver and method of processing data of broadcast receiver

A broadcasting receiver and a data processing method thereof are provided to receive and process plural mobile broadcasting services at the same time and output the processed service at the same time, thereby improving satisfaction of a user. If a broadcasting receiver is converted into a discontinuous reception mode, a signal receiving part(611) repeats a preset wake-up section and a sleep section. The signal receiving part receives a broadcast signal including mobile broadcasting service data and main broadcast service data in the wake-up section. A base data detection part(614) detects base data within the received broadcast signal. An equalizer(613) performs channel equalization of the received mobile broadcasting service data by using the detected base data.
