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 for transmitting broadcast signals, the method comprising:

generating a plurality of packets including service data for a service and bootstrapping information for Electronic Service Guide (ESG) information related to the service,

wherein each packet includes a header and a payload, the header including type information indicating a type of a packet;

encoding, by a processor, the service data and the bootstrapping information in the plurality packets; and

transmitting, by a transmitter, the broadcast signals including the encoded service data and the encoded bootstrapping information,

wherein the broadcast signals are transmitted via a first channel,

wherein the bootstrapping information includes indication information indicating whether or not the ESG information is transmitted via a second channel,

wherein, when the ESG information is transmitted via the second channel, the bootstrapping information further includes location information for acquiring the ESG information, and

wherein, when the ESG information is transmitted via the first channel, the ESG information and the service data are encapsulated into User Datagram Protocol/Internet Protocol (UDP/IP) packets.

2. The method of claim 1, wherein the service data is transmitted in Asynchronous Layered Coding/Layered Coding Transport (ALC/LCT) packets.

3. The method of claim 1, wherein the broadcast signals further includes signaling information including service type information indicating a type of the service, major channel information and minor channel information for the service, and hidden information of the service.

4. An apparatus for transmitting broadcast signals, the apparatus comprising:

an adaptation layer packet generator to generate a plurality of packets including service data for a service and bootstrapping information for Electronic Service Guide (ESG) information related to the service,

wherein each packet includes a header and a payload, the header including type information indicating a type of a packet;

a processor to encode the service data and the bootstrapping information in the plurality of packets; and

a transmitter to transmit the broadcast signals including the encoded service data and the encoded bootstrapping information,

wherein the broadcast signals are transmitted via a first channel,

wherein the bootstrapping information includes indication information indicating whether or not the ESG information is transmitted via a second channel,

wherein, when the ESG information is transmitted via the second channel, the bootstrapping information further includes location information for acquiring the ESG information, and

wherein when the ESG information is transmitted via the first channel, the ESG information and the service data are encapsulated into User Datagram Protocol/Internet Protocol (UDP/IP) packets.

5. The apparatus of claim 4, wherein the service data is transmitted in Asynchronous Layered Coding/Layered Coding Transport (ALC/LCT) packets.

6. The apparatus of claim 4, wherein the broadcast signals further includes signaling information including service type information indicating a type of the service, major channel information and minor channel information for the service, and hidden information of the service.
