Digital broadcasting system and method of processing data in digital broadcasting system

A broadcast receiver comprising:

• a tuner for receiving a broadcast signal, the broadcast signal comprising mobile service data, a service map table (SMT) including access information of the mobile service data, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes binding information between an ensemble and mobile services included in the ensemble, and wherein the TPC data includes FIC version information for indicating an update of the FIC data;
• a decoder for decoding Reed-Solomon (RS) frames including the mobile service data from the received broadcast signal, wherein the RS frames belong to the ensemble;
• a first handler for acquiring the SMT from the ensemble, wherein the SMT is segmented into at least one SMT section, wherein the at least one SMT section is included in at least one of the RS frames, wherein the access information comprises an Internet protocol (IP) address and a user datagram protocol (UDP) port number of the mobile service data, wherein the at least one SMT section comprises a section header and a section body, and wherein the section header includes an ensemble identifier to identify the ensemble and the section body includes the access information of the mobile service data;
• and
• a second handler for processing the mobile service data based on the access information of the SMT.

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, thereby packaging the mobile service data into RS frames belonging to an ensemble;
• mapping each of the RS frames into a plurality of groups, wherein each group includes a portion of data included in a corresponding RS frame, known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes binding information between the ensemble and mobile services included in the ensemble, 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,
• wherein a service map table (SMT) which includes access information of the mobile service data is segmented into at least one SMT section, wherein the at least one SMT section is included in at least one of the RS frames, wherein the access information comprises an Internet protocol (IP) address and a user datagram protocol (UDP) port number of the mobile service data, wherein the at least one SMT section comprises a section header and a section body, and wherein the section header includes an ensemble identifier to identify the ensemble and the section body includes the access information of the mobile service data.

A broadcast transmitter comprising:
