Patent ID: 8135077

Claim:
A broadcast receiver comprising: a broadcasting module for receiving and processing a mobile broadcast signal; at least one function module for outputting at least a video output or an audio output; a signal receiving unit for receiving a broadcast signal including mobile service data and main service data; a Reed-Solomon (RS) frame decoder for performing Cyclic Redundancy Check (CRC)-decoding and RS-decoding on an RS frame in order to correct errors in the corresponding mobile service data, wherein the RS frame includes at least one data packet corresponding to the mobile service data, an RS parity generated based upon the at least one data packet and a CRC checksum generated based upon the mobile service data and the RS parity, wherein the broadcast signal further includes a transmission frame, wherein a parade of data groups are received through slots within the transmission frame, the slots being basic time periods for multiplexing the mobile service data and the main service data, wherein each data group of multiple parades is assigned to a single transmission frame, wherein a plurality of consecutive data groups within the parade are assigned to be spaced apart from one another within the transmission frame, wherein each of the data groups includes the mobile service data, signaling information and known data sequences, and wherein the signaling information includes fast information channel (FIC) data and transmission parameter channel (TPC) data indicating a version of the FIC data, the FIC data having binding information between a service of the mobile service data and an ensemble; a decoding unit for extracting at least map information or traffic information from the error-corrected mobile service data and outputting the extracted at least map information or traffic information; and a controller for controlling output of the at least the video output or the audio output of the least one function module and output of at least a video output or an audio output of the broadcasting module when a mode shift occurs between the broadcasting module and the at least one function module.
