BROADCAST RECEIVER AND METHOD OF PROCESSING DATA
First Claim
1. A broadcast receiver, comprising:
- a signal receiving unit for receiving broadcast signal multiplexed mobile broadcast service data including text information and main broadcast service data, wherein the mobile broadcast service data configures a RS frame, and wherein the RS frame includes at least one data packet corresponding to the mobile broadcast service data, an RS parity generated based upon the at least one data packet, and a CRC checksum generated based upon the at least one data packet and the RS parity;
a RS frame decoder for performing CRC-decoding and RS-decoding on the RS frame, thereby correcting errors occurred in the corresponding mobile broadcast service data;
a decoding unit for decoding the text information included in the error-corrected mobile broadcast service data, and outputting the decoded text information;
a text-to-speech (TTS) module for converting the outputted text information to a voice signal;
a voice output unit for outputting the converted voice signal; and
a control unit for controlling the voice output unit.

Abstract
A broadcast receiver and a method of processing data are disclosed. The broadcast receiver includes a signal receiving unit, a RS frame decoder, a decoding unit, a text-to-speech (TTS) module, a voice output unit, and a control unit. The signal receiving unit receives broadcast signal multiplexed mobile broadcast service data including text information and main broadcast service data. The RS frame decoder performs decoding on the RS frame, thereby correcting errors occurred in the corresponding mobile broadcast service data. The decoding unit decodes the text information included in the error-corrected mobile broadcast service data. The text-to-speech (TTS) module converts the text information to a voice signal. The voice output unit outputs the converted voice signal. The control unit controls the voice output unit.
