Digital broadcasting receiver and method for controlling the same

A method of processing broadcast data in a broadcast transmitter, the method comprising:

• performing, by a Reed Solomon (RS) encoder, RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data and a signaling information table including access information of the mobile service data, thereby forming an RS frame;
• dividing the RS frame into a plurality of groups, wherein each group includes a portion of data included in the RS frame, a plurality of known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes information for rapid mobile service acquisition, and wherein the TPC data includes FIC version information for indicating an update of the FIC data;
• and
• transmitting a broadcast signal including the plurality of groups,
