BROADCAST RECEIVER AND METHOD OF PROCESSING DATA
First Claim
1. A digital broadcast system, comprising:
- a receiving unit for receiving a broadcast signal multiplexed mobile broadcast service data including a first information associated with safety/security 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 extracting the first information from the error-corrected mobile broadcast service data, thereby decoding the extracted data with at least one of an audio decoder, a video decoder, and a data decoder; and
an output unit for outputting the first information decoded by the decoder in a form of at least one of a text, a voice message, and an image.

Abstract
A broadcast receiver, and a method of processing data are disclosed. The broadcast receiver includes a receiving unit, a RS frame decoder, a decoding unit, and an output unit. The receiving unit receives a broadcast signal multiplexed mobile broadcast service data including a first information associated with safety/security and main broadcast service data. The RS frame decoder performs CRC-decoding and RS-decoding on the RS frame, thereby correcting errors occurred in the corresponding mobile broadcast service data. The decoding unit extracts the first information from the error-corrected mobile broadcast service data, thereby decoding the extracted data with at least one of an audio decoder, a video decoder, and a data decoder. The output unit outputs the first information decoded by the decoder in a form of at least one of a text, a voice message, and an image.
