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 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 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.

2. The method according to claim 1, wherein the status information of the first virtual channel indicates whether the first virtual channel is any one of an active channel, an inactive channel, a hidden channel, and a software download channel.

3. The method according to claim 2, further comprising:

if the status information of the first virtual channel is the active channel,

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 associated with 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.

4. The method according to claim 2, further comprising:

if the status information of the first virtual channel is the inactive channel,

acquiring ensemble identification information transferring the second virtual channel using the binding information, and receiving at least one mobile service data group transferring an ensemble associated with the ensemble identification information;

parsing service table information contained in the ensemble; and

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

5. The method according to claim 2, further comprising:

acquiring version information of service guide information associated with the mobile service data from the fast-information-channel signaling information;

acquiring ensemble identification information exclusively transferring the service guide information according to the version information of the service guide information, and receiving at least one mobile service data group transferring an ensemble associated with the ensemble identification information; and

displaying the service guide information transferred in the ensemble.

6. The method according to claim 2, wherein the status information of the first virtual channel includes either of inactive time information and active time information of the first virtual channel.

7. A digital broadcasting system comprising:

a baseband processor configured to extract fast-information-channel signaling information including binding information describing a relationship between a first virtual channel of mobile service data and an ensemble transferring the first virtual channel, and status information of the first virtual channel, from a broadcast signal;

a management processor configured to acquire the binding information and the channel status information by decoding the fast-information-channel signaling information; and

a presentation processor configured to display content data contained in the mobile service data according to the channel status information.

8. The digital broadcasting system according to claim 7, wherein the status information of the first virtual channel indicates whether the first virtual channel is any one of a active channel, an inactive channel, a hidden channel, and a software download channel.

9. The digital broadcasting system according to claim 7, wherein:

if the status information of the first virtual channel is an active channel,

the management processor acquires ensemble identification information transferring the first virtual channel using the binding information, and parses service table information contained in an ensemble associated with the ensemble identification information;

the baseband processor receives at least one mobile service data group transferring the ensemble associated with the ensemble identification information; and

the presentation processor decodes content data contained in the first virtual channel using the parsed service table information, and displays the decoded content data.

10. The digital broadcasting system according to claim 7, wherein:

if the status information of the first virtual channel is an inactive channel,

the management processor acquires ensemble identification information transferring the second virtual channel using the binding information, and parses service table information contained in an ensemble associated with the ensemble identification information;

the baseband processor receives at least one mobile service data group transferring the ensemble associated with the ensemble identification information; and

the presentation processor decodes content data contained in the second virtual channel using the parsed service table information, and displays the decoded content data.

11. The digital broadcasting system according to claim 7, wherein the status information of the first virtual channel includes either of inactive time information and active time information of the first virtual channel.
