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 a signaling information table comprising access information of the mobile service data, thereby building an RS frame including the mobile service data and the signaling information table;

mapping a portion of the RS frame into at least one region of a group that has a plurality of regions, 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 for a mobile service, and wherein the TPC data includes FIC version information for identifying an update of the FIC data; and

transmitting a broadcast signal including the group,

wherein the status information for the mobile service is assigned with 2 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 or not hidden.

2. 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.

3. The method of claim 2, wherein the header further includes error indicating information indicating whether or not an error is detected in the FIC data.

4. The method of claim 1, wherein the signaling information table is carried by at least one section, each section comprising a section header and a section body, wherein the section header comprises an ensemble identifier to identify an ensemble and the section body comprises access information of the mobile service data, and wherein the RS frame belongs to the ensemble.

5. 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.

6. A broadcast transmitter comprising:

a Reed-Solomon (RS) frame encoder for performing RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data and a signaling information table comprising access information of the mobile service data, thereby building an RS frame including the mobile service data and the signaling information table;

a group formatting means for mapping a portion of the RS frame into at least one region of a group that has a plurality of regions, 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 for a mobile service, and wherein the TPC data includes FIC version information for identifying an update of the FIC data; and

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

wherein the status information for the mobile service is assigned with 2 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 or not hidden.

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

8. The broadcast transmitter of claim 7, wherein the header further includes error indicating information indicating whether or not an error is detected in the FIC data.

9. The broadcast transmitter of claim 6, wherein the signaling information table is carried by at least one section, each section comprising a section header and a section body, wherein the section header comprises an ensemble identifier to identify an ensemble and the section body comprises access information of the mobile service data, and wherein the RS frame belongs to the ensemble.

10. 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.
