Abstract

A receiving system and a data processing method are disclosed. The receiving system includes a receiving unit, a demodulator, a first handler, and a second handler. The receiving unit receives a broadcast signal including fast information channel (FIC) data, mobile service data, and a service signaling channel, the FIC data including a field indicating that a table signaling service guide bootstrap information to the service signaling channel is included therein, and the mobile service data and the service signaling channel are packetized into an RS frame belonging to a desired ensemble. The demodulator demodulates the received broadcast signal. The first handler acquires service guide bootstrap information from the table included in the service signaling channel. And, the second handler accesses a service guide announcement channel by using the service guide bootstrap information.

Claims

1. A receiving system for processing broadcast data, the receiving system comprising:

a tuner to receive a broadcast signal that includes a transmission frame comprising one or more sub-frames, the transmission frame including broadcast service data for a broadcast service, first signaling information for fast service acquisition, second signaling information describing at least one component of the broadcast service, and physical layer parameters,

wherein the first signaling information includes information for identifying whether a service guide is provided, version information related to the second signaling information, and protection information for indicating whether the at least one component is protected,

wherein the second signaling information includes access information of a service guide delivery descriptor (SGDD) describing a service guide delivery unit (SGDU) that includes service guide data,

wherein the access information of the SGDD includes transport session identification information, destination address information and destination port information, and

wherein the physical layer parameters include information related to the one or more sub-frames;

a demodulator to demodulate the received broadcast signal;

a signaling decoder to decode the physical layer parameters in the demodulated broadcast signal; and

a decoder to decode the broadcast service data in the demodulated broadcast signal.

2. The receiving system of claim 1, wherein the SGDU is received in a Layered Coding Transport (LCT) method of a unidirectional transport protocol.

3. The receiving system of claim 1, further comprising:

a first handler to access the SGDD based on the first signaling information and the second signaling information; and

a second handler to acquire the service guide data in the SGDU based on the accessed SGDD.

4. The receiving system of claim 3, wherein the acquired service guide data are at least stored in a storage unit or displayed on a screen.

5. A method of processing broadcast data in a receiving system, the method comprising:

receiving a broadcast signal that includes a transmission frame comprising one or more sub-frames, the transmission frame including broadcast service data for a broadcast service, first signaling information for fast service acquisition, second signaling information describing at least one component of the broadcast service, and physical layer parameters,

wherein the first signaling information includes information for identifying whether a service guide is provided, version information related to the second signaling information, and protection information for indicating whether the at least one component is protected,

wherein the second signaling information includes access information of a service guide delivery descriptor (SGDD) describing a service guide delivery unit (SGDU) that includes service guide data,

wherein the access information of the SGDD includes transport session identification information, destination address information and destination port information, and

wherein the physical layer parameters include information related to the one or more sub-frames;

demodulating the received broadcast signal;

decoding the physical layer parameters in the demodulated broadcast signal; and

decoding the broadcast service data in the demodulated broadcast signal.

6. The method of claim 5, wherein the SGDU is received in a Layered Coding Transport (LCT) method of a unidirectional transport protocol.

7. The method of claim 5, further comprising:

accessing the SGDD based on the first signaling information and the second signaling information; and

acquiring the service guide data in the SGDU based on the accessed SGDD.

8. The method of claim 7, wherein the acquired service guide data are at least stored in a storage unit or displayed on a screen.
