Abstract

A digital broadcasting system and a data processing method are disclosed. The method includes receiving a data processing method includes receiving a broadcast signal in which main service data and mobile service data are multiplexed, acquiring transmission-parameter-channel signaling information including transmission parameter information of the mobile service data, and fast-information-channel signaling information, acquiring binding information describing a relationship between at least one ensemble transferring the mobile service data and a first virtual channel contained in the at least one ensemble by decoding the fast-information-channel, and acquiring status information of the first virtual channel, displaying content data contained in the mobile service data according to the binding information and the status information of the first virtual channel.

Claims

1. 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 building one or two RS frames per a parade depending on RS frame mode information, the RS frame mode information indicating a single frame mode or a dual frame mode;

mapping a portion of the one or two RS frames into a group, wherein the group further comprises known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes status information of a mobile service, and wherein the TPC data includes FIC version information for identifying an update of the FIC data and the RS frame mode information; and

transmitting a broadcast signal including the group,

wherein the status information of the mobile service is assigned with two bits, and wherein a first bit indicates whether the mobile service is active or inactive and a second bit indicates whether the mobile service is hidden.

2. The method of claim 1, wherein one RS frame per the parade is built if the RS frame mode information indicates the single frame mode.

3. The method of claim 2, wherein the group comprises regions A, B, C, and D, and wherein a portion of the one RS frame is mapped into regions A, B, C, and D of the group.

4. The method of claim 1, wherein two RS frames per the parade are built if the RS frame mode information indicates the dual frame mode.

5. The method of claim 4, wherein the group comprises regions A, B, C, and D, wherein a portion of one RS frame is mapped into regions A and B of the group and wherein a portion of the other RS frame is mapped into regions C and D of the group.

6. The method of claim 1, wherein the FIC data includes a 2-byte header including FIC type information and a 35-byte payload including the status information.

7. The method of claim 6, wherein the header further includes error indicating information indicating whether an error is detected in the FIC data.

8. The method of claim 1, 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.

9. A broadcast transmitter comprising:

a Reed-Solomon (RS) encoder for performing RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data and building one or two RS frames per a parade depending on RS frame mode information, the RS frame mode information indicating a single frame mode or a dual frame mode;

a group formatting means for mapping a portion of the one or two RS frames into a group, wherein the group further comprises known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes status information of a mobile service, and wherein the TPC data includes FIC version information for identifying an update of the FIC data and the RS frame mode information; and

a transmitting means for transmitting a broadcast signal including the group,

wherein the status information of the mobile service is assigned with two bits, and wherein a first bit indicates whether the mobile service is active or inactive and a second bit indicates whether the mobile service is hidden.

10. The broadcast transmitter of claim 9, wherein one RS frame per the parade is built if the RS frame mode information indicates the single frame mode.

11. The broadcast transmitter of claim 10, wherein the group comprises regions A, B, C, and D, and wherein a portion of the one RS frame is mapped into regions A, B, C, and D of the group.

12. The broadcast transmitter of claim 9, wherein two RS frames per the parade are built if the RS frame mode information indicates the dual frame mode.

13. The broadcast transmitter of claim 12, wherein the group comprises regions A, B, C, and D, wherein a portion of one RS frame is mapped into regions A and B of the group and wherein a portion of the other RS frame is mapped into regions C and D of the group.

14. The broadcast transmitter of claim 9, wherein the FIC data includes a 2-byte header including FIC type information and a 35-byte payload including the status information.

15. The broadcast transmitter of claim 14, wherein the header further includes error indicating information indicating whether an error is detected in the FIC data.

16. The broadcast transmitter of claim 9, 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.
