Abstract

The present invention provides a data processing method. The 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 any of the at least one ensemble by decoding fast-information-channel signaling information, acquiring ensemble identification information transferring the first virtual channel using the binding information, and receiving at least one mobile service data group transferring an ensemble according to the ensemble identification information, parsing service table information contained in the ensemble and decoding content data contained in the first virtual channel using the parsed service table information, and displaying the decoded content data.

Claims

1. A data processing method comprising:

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 any of the at least one ensemble by decoding fast-information-channel signaling information;

acquiring ensemble identification information transferring the first virtual channel using the binding information, and receiving at least one mobile service data group transferring an ensemble according to the ensemble identification information;

parsing service table information contained in the ensemble; and

decoding content data contained in the first virtual channel using the parsed service table information, and displaying the decoded content data.

2. The method according to claim 1, wherein the fast-information-channel signaling information is divided into a plurality of segments according to the mobile service data group.

3. The method according to claim 1, wherein the fast-information-channel signaling information includes channel type information indicating a type of a service transferred to the virtual channel.

4. The method according to claim 1, wherein the fast-information-channel signaling information includes a major-channel number and a minor-channel number of the virtual channel, which is contained in each ensemble according to the ensemble identification information.

5. A data processing method comprising:

performing a first error correction encoding process on fast-information-channel signaling information including binding information, in which the binding information describes a relationship between a first virtual channel in any of at least one ensemble transferring mobile service data and the ensemble transferring the first virtual channel;

performing a second error correction encoding process on mobile service data to be transferred to the ensemble and service table information describing channel information of the ensemble; and

multiplexing the encoded fast-information-channel signaling information and the mobile service data, multiplexing the multiplexed mobile service data and main service data, and modulating the resultant multiplexed data.

6. The method according to claim 5, wherein the fast-information-channel signaling information includes a major-channel number and a minor-channel number of a virtual channel contained in the ensemble.

7. The method according to claim 5, wherein the fast-information-channel signaling information includes channel type information indicating a type of a service transferred to the virtual channel.

8. The method according to claim 5, wherein the fast-information-channel signaling information includes transport stream identification information of the broadcast signal.

9. A digital broadcasting system comprising:

a baseband processor configured to acquire transmission-parameter-channel signaling information including transmission parameter information of mobile service data and fast-information-channel signaling information from a broadcast signal, and receive a mobile service data group which transmits an ensemble according to fast-information-channel signaling information including binding information describing a relationship between a first virtual channel of the mobile service data and the ensemble transferring the first virtual channel;

a management processor configured to acquire the binding information by decoding the fast-information-channel signaling information, and parsing service table information of the ensemble received according to the binding information; and

a presentation processor configured to decode mobile service data of the first virtual channel according to the service table information, and displaying content data contained in the decoded mobile service data.

10. The digital broadcasting system according to claim 9, wherein the transmission-parameter-channel signaling information includes version information of the fast-information-channel signaling information.

11. The digital broadcasting system according to claim 9, wherein the fast-information-channel signaling information indicates a type of a service transferred to the first virtual channel.

12. The digital broadcasting system according to claim 9, wherein the baseband processor receives a time-discontinuous mobile service data group, and receives the ensemble including the first virtual channel by using the fast-information-channel signaling information.
