Abstract

A receiving system and a data processing method are disclosed. The receiving system includes a receiving unit, a demodulator, a first handler, a second handler, and a third handler. The receiving unit receives a broadcast signal comprising fast information channel (FIC) data, transmission parameter channel (TPC) data, and mobile service data packetized into an RS frame. The demodulator demodulates the broadcast signal. The first handler configures an ensemble from the RS frame, so as to acquire first signaling information including access information of the mobile service. The second handler receives second signaling information of the mobile service, so as to acquire content identification information of a second data type from the received second signaling information. And, the third handler extracts a mobile service identifier and a content identifier of a first data type from the first signaling information and constructs content identification information of a second data type.

Claims

1. A method of receiving a broadcast signal in a receiver, the method comprising:

receiving the broadcast signal including a transmission frame, the transmission frame comprising a collection of data groups, wherein the collection of data groups carries an ensemble of mobile data and signaling data, the signaling data including first signaling data and second signaling data, wherein the first signaling data describes the transmission frame and the collection of data groups and includes version information for identifying an update of the second signaling data, wherein the second signaling data includes binding information between a service of the mobile data and the ensemble, and wherein the ensemble includes the mobile data and at least one signaling table for describing the service of the mobile data;

demodulating the broadcast signal;

decoding the signaling data including the first signaling data and the second signaling data from the demodulated broadcast signal, wherein decoding the signaling data comprises;

performing turbo decoding on the signaling data;

de-multiplexing the first signaling data and the second signaling data from the turbo decoded signaling data;

performing first Reed-Solomon (RS) decoding on the de-multiplexed first signaling data;

de-interleaving the de-multiplexed second signaling data; and

performing second RS decoding on the de-interleaved second signaling data;

accessing the ensemble based on the second RS decoded second signaling data;

decoding the at least one signaling table in the ensemble; and

accessing the service of the mobile data based on the at least one signaling table of the ensemble,

wherein the second signaling data includes a chunk header and a chunk payload,

wherein the chunk header includes a major protocol version field and a minor protocol version field,

wherein the major protocol version field represents a non-backward-compatible level of change for a major version of syntax and semantics of the second signaling data and the minor protocol version field represents a backward compatible level of change for a minor version of syntax and semantics of the second signaling data,

wherein the chunk payload includes a ensemble protocol version field, and

wherein the ensemble protocol version field represents a version of a structure of the ensemble.

2. The method of claim 1, wherein the at least one signaling table includes a descriptor for identifying and labeling content being broadcast in the service, the method further comprising:

receiving service guide data based on the at least one signaling table.

3. The method of claim 2, wherein:

the at least one signaling table further includes a mobile service identifier and content identification information of a first data type; and

the service guide data includes content identification information of a second data type.

4. The method of claim 3, wherein:

the first data type corresponds to a binary type; and

the second data type corresponds to an Extensible Markup Language (XML) type.

5. The method of claim 3, further comprising:

constructing new content identification information of the second data type using the mobile service identifier and content identification information of the first data type.

6. The method of claim 5, wherein the constructed new content identification information of the second data type corresponds to a Uniform Resource Identifier (URI) type.

7. The method of claim 6, wherein the constructed new content identification information of the second data type includes an international country code.

8. The method of claim 6, wherein the constructed new content identification information of the second data type includes Coordinated Universal Time (UTC) reference time of a day extracted from the at least one signaling table.

9. The method of claim 5, further comprising:

mapping the constructed new content identification information of the second data type with the content identification information of the second data type from the service guide data.

10. The method of claim 9, wherein, the constructed new content identification information of the second data type includes a transport stream identifier extracted from the second signaling data when the service of the mobile data corresponds to a local service.
