Abstract

The present invention relates to a digital broadcasting system for transmitting/receiving a digital broadcasting signal and a method of processing data. In one aspect of the present invention provides a method of processing data, the method including receiving a broadcasting signal in which mobile service data and main service data are multiplexed, demodulating the received broadcasting signal, obtaining an identifier indicating that data frame of the broadcasting signal includes service guide information, decoding and storing the service guide information from the data frame; and outputting a service included in the mobile service data according to the decoded service guide information.

Claims

1. A method of processing broadcast data in a receiver, the method comprising:

receiving a broadcast signal including service data for a service and signaling information,

wherein the broadcast signal is received via a first channel,

wherein Electronic Service Guide (ESG) information related to the service is received via one of the first channel or a second channel,

wherein, when the ESG information is received via the first channel, the ESG information is included in User Datagram Protocol/Internet Protocol (UDP/IP) packets and the signaling information includes destination address information and destination port information for acquiring the ESG information, and

wherein, when the ESG information is received via the second channel, the signaling information includes uniform resource location information for acquiring the ESG information;

demodulating the broadcast signal;

decoding the service data and the signaling information in the demodulated broadcast signal;

acquiring the ESG information that is received via one of the first channel or the second channel based on the signaling information; and

storing and displaying the ESG information.

2. The method of claim 1, wherein the first channel is a broadcast channel and the second channel is a broadband channel.

3. The method of claim 1, wherein, when the ESG information is received via the first channel, the signaling information further includes source address information for acquiring the ESG information.

4. The method of claim 1, wherein, when the ESG information is received via the first channel, the ESG information is received in a Layered Coding Transport (LCT) packet of a session and wherein the signaling information further includes transport session identification information.

5. The method of claim 1, further comprising:

generating a request for the ESG information and sending the request to a server providing the ESG information via the second channel.

6. A receiver for processing broadcast data, the receiver comprising:

a tuner to receive a broadcast signal including service data for a service and signaling information,

wherein the broadcast signal is received via a first channel,

wherein Electronic Service Guide (ESG) information related to the service is received via one of the first channel or a second channel,

wherein, when the ESG information is received via the first channel, the ESG information is included in User Datagram Protocol/Internet Protocol (UDP/IP) packets and the signaling information includes destination address information and destination port information for acquiring the ESG information, and

wherein, when the ESG information is received via the second channel, the signaling information includes uniform resource location information for acquiring the ESG information;

a demodulator to demodulate the broadcast signal;

a decoder to decode the service data and the signaling information in the demodulated broadcast signal;

a processor to acquire the ESG information that is received via one of the first channel or the second channel based on the signaling information; and

a manager to store and display the ESG information.

7. The receiver of claim 6, wherein the first channel is a broadcast channel and the second channel is a broadband channel.

8. The receiver of claim 6, wherein, when the ESG information is received via the first channel, the signaling information further includes source address information for acquiring the ESG information.

9. The receiver of claim 6, wherein, when the ESG information is received via the first channel, the ESG information is received in a Layered Coding Transport (LCT) packet of a session and wherein the signaling information further includes transport session identification information.

10. The receiver of claim 6, wherein the processor further generates a request for the ESG information and sends the request to a server providing the ESG information via the second channel.
