Digital broadcasting system and method of processing data
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.
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 including bootstrapping information for acquiring Electronic Service Guide (ESG) information related to the service,
wherein the broadcast signal is received via a broadcast channel,
wherein the ESG information is received via one of the broadcast channel or a broadband channel,
wherein, when the ESG information is received via the broadcast channel, the ESG information is delivered in User Datagram Protocol/Internet Protocol (UDP/IP) packets and the bootstrapping information includes destination address information and destination port information for acquiring the ESG information, and
wherein, when the ESG information is received via the broadband channel, the ESG information is delivered in Transmission Control Protocol/Internet Protocol (TCP/IP) packets and the bootstrapping 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 broadcast channel or the broadband channel based on the signaling information;
storing the ESG information in a storage;
display the ESG information; and
providing a user interface to select at least one content in the ESG information by a user input signal.
2. The method of claim 1 , wherein, when the ESG information is received via the broadcast channel, the bootstrapping information further includes source address information for acquiring the ESG information.
3. The method of claim 1 , wherein, when the ESG information is received via the broadcast 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.
4. A receiver for processing broadcast data, the receiver comprising:
a tuner configured to receive a broadcast signal including service data for a service and signaling information including bootstrapping information for acquiring Electronic Service Guide (ESG) information related to the service,
wherein the broadcast signal is received via a broadcast channel,
wherein the ESG information is received via one of the broadcast channel or a broadband channel,
wherein, when the ESG information is received via the broadcast channel, the ESG information is delivered in User Datagram Protocol/Internet Protocol (UDP/IP) packets and the bootstrapping information includes destination address information and destination port information for acquiring the ESG information, and
wherein, when the ESG information is received via the broadband channel, the ESG information is delivered in Transmission Control Protocol/Internet Protocol (TCP/IP) packets and the bootstrapping information includes uniform resource location information for acquiring the ESG information;
a demodulator configured to demodulate the broadcast signal;
a decoder configured to decode the service data and the signaling information in the demodulated broadcast signal;
a processor configured to acquire the ESG information that is received via one of the broadcast channel or the broadband channel based on the signaling information;
a storage configured to store the ESG information;
an output unit configured to display the ESG information; and
an interface unit configured to receive a user input signal to select at least one content in the ESG information.
5. The receiver of claim 4 , wherein, when the ESG information is received via the broadcast channel, the bootstrapping information further includes source address information for acquiring the ESG information.
6. The receiver of claim 4 , wherein, when the ESG information is received via the broadcast 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.
7. 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 broadband channel.
8. The receiver of claim 4 , wherein the processor further generates a request for the ESG information and sends the request to a server providing the ESG information via the broadband channel.
