The digital broadcast receiving system includes a baseband processor, a management processor, and a presentation processor. The baseband processor receives a broadcast signal including mobile service data and main service data. Herein, the mobile service data configure a Reed-Solomon (RS) frame, and the RS frame includes mobile service data and at least one channel configuration information on the mobile service data. The management processor acquires simple guide information on at least one of a current program and a next program of a corresponding channel from the channel configuration information and stores the acquired simple guide information. The presentation processor receives simple guide information of any one of the current program and the next program, wherein the programs are provided as mobile service through a user-selected channel, from the management processor and displays the received simple guide information on a portion of a display screen of the corresponding channel.
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 and status 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, regularly spaced known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data; and
wherein the FIC data includes information for rapid mobile service acquisition, wherein the TPC data includes FIC version information for indicating an update of the FIC data, and wherein at least two of the known data sequences are spaced 16 segments apart and have different lengths.
2. The method of claim 1, wherein the status information indicates whether the mobile service data is active or not.
3. The method of claim 1, wherein the status information indicates whether the mobile service data is hidden or not.
5. The method of claim 1, wherein the signaling information table is encapsulated with a user datagram protocol and IP (UDP/IP) header including a well-known IP address and a well-known UDP port number.
an RS encoder for performing Reed Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data and a signaling information table, the signaling information including access information and status information of the mobile service data, thereby forming an RS frame;
a group formatting means for dividing the RS frame into a plurality of groups, wherein each group includes a portion of data included in the RS frame, regularly spaced known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data; and
7. The broadcast transmitter of claim 6, wherein the status information indicates whether the mobile service data is active or not.
8. The broadcast transmitter of claim 6, wherein the status information indicates whether the mobile service data is hidden or not.
9. The broadcast transmitter of claim 6, wherein the FIC data and the TPC data are positioned between a first known data sequence and a second known data sequence of the known data sequences.
10. The broadcast transmitter of claim 6, wherein the signaling information table is encapsulated with a user datagram protocol and IP (UDP/IP) header including a well-known IP address and a well-known UDP port number.
11. A method of processing broadcast data in a broadcast receiver, the method comprising:
receiving a broadcast signal, the broadcast signal comprising mobile service data, a signaling information table including access information and status information of the mobile service data, regularly spaced known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the mobile service data and the signaling information table are encapsulated into at least one of a plurality of RS frames;
compensating channel distortion of the demodulated broadcast signal based upon at least one of the known data sequences;
extracting the signaling information table from the demodulated broadcast signal;
acquiring the status information of the mobile service data from the extracted signaling information table; and

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, wherein the at least one of a plurality of RS frames is divided into a plurality of groups, each group including a portion of data included in the RS frame, the known data sequences, the FIC data, and the TPC data, and wherein at least two of the known data sequences are spaced 16 segments apart and have different lengths.
12. The method of claim 11, wherein the status information indicates whether the mobile service data is active or not.
13. The method of claim 11, wherein the status information indicates whether the mobile service data is hidden or not.
14. The method of claim 11, further comprising displaying a message indicating the availability of the mobile service data on a portion of a screen.
15. The method of claim 11, wherein the FIC data and the TPC data are positioned between a first known data sequence and a second known data sequence of the known data sequences.
16. A broadcast receiver comprising:
a tuner for receiving a broadcast signal, the broadcast signal comprising mobile service data, a signaling information table including access information and status information of the mobile service data, regularly spaced known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the mobile service data and the signaling information table are encapsulated into at least one of a plurality of RS frames;
an equalizer for compensating channel distortion of the demodulated broadcast signal based upon at least one of the known data sequences;
a first handler for extracting the signaling information table from the demodulated broadcast signal and acquiring the status information of the mobile service data from the extracted signaling information table; and
a second handler for determining availability of the mobile service data using the status information,
17. The broadcast receiver of claim 16, wherein the status information indicates whether the mobile service data is active or not.
18. The broadcast receiver of claim 16, wherein the status information indicates whether the mobile service data is hidden or not.
19. The broadcast receiver of claim 16, further comprising a display unit for displaying a message indicating the availability of the mobile service data on a portion of a screen.
20. The broadcast receiver of claim 16, wherein the FIC data and the TPC data are positioned between a first known data sequence and a second known data sequence of the known data sequences.
