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 for transmitting broadcast signals, the method comprising:
encoding, by an encoder processor, service data of a service, signaling information about the encoded service data, and bootstrapping information for Electronic Service Guide (ESG) information related to the service; and
transmitting, by a transmitter, the broadcast signals including the encoding service data, the encoded signaling information, and the encoded bootstrapping information
wherein the service data is transmitted in Asynchronous Layered Coding/Layered Coding Transport (ALC/LCT) packets,
wherein the broadcast signals are transmitted via a first channel, and
wherein the bootstrapping information includes information indicating whether or not the ESG information is transmitted via a second channel.
2. The method of claim 1 , wherein the bootstrapping information includes destination internet protocol (IP) address information containing a destination address of the ALC/LCT packets carrying the service, port information containing a port number of the ALC/LCT wickets carrying the service, and source IP address information containing a source address of the ALC/LCT packets carrying the service.
3. The method of claim 1 , wherein the bootstrapping information is transmitted via a first channel, and
wherein the bootstrapping information includes information indicating whether or not Electronic Service Guide (ESG) information is transmitted via a second channel.
4. The method of claim 3 , wherein the bootstrapping information includes location information for acquiring die ESG information via the second channel.
5. The method of claim 1 , wherein the service data includes Electronic Service Guide (ESG) information.
6. An apparatus for transmitting broadcast signals, the apparatus comprising:
an encoder processor to encode service data of a service, signaling information about the encoded service data, and bootstrapping information for Electronic Service Guide (ESG) information related to the service; and
a transmitter to transmit the broadcast signals including the encoding service data, the encoded signaling information, and the encoded bootstrapping information wherein the service data is transmitted in Asynchronous Layered Coding/Layered Coding Transport (ALC/LCT) packets, wherein the broadcast signals are transmitted via a first channel, and
wherein the bootstrapping information includes information indicating whether or not the ESG information is transmitted via a second channel.
7. The apparatus of claim 6 , wherein the bootstrapping information includes destination internet protocol (IP) address information containing a destination address of the ALC/LCT packets carrying the service, port information containing a port number of the ALC/LCT packets carrying the service, and source IP address information containing a source address of the ALC/LCT packets carrying the service.
8. The apparatus of claim 6 , wherein the bootstrapping information is transmitted via a first channel, and
wherein the bootstrapping information includes information indicating whether or not Electronic Service Guide (ESG) information is transmitted via a second channel.
9. The apparatus of claim 8 , wherein the bootstrapping information includes location information for acquiring the ESG information via the second channel.
10. The apparatus of claim 6 , wherein the service data includes Electronic Service Guide(ESG) information.
