1. A method of processing data in a digital receiving apparatus, the method comprising:
receiving a broadcast signal including low level signaling data,
wherein the low level signaling data is carried via a specific data pipe (DP),
wherein the low level signaling data includes service category information, the service category information is used to identify an AV service, an audio only service or an ESG (electronic service guide) service,
wherein the low level signaling data includes bootstrap information that allows the digital receiving apparatus to discover service layer signaling information,
wherein when the service layer signaling information is transmitted via a broadband network, the bootstrap information includes URL data for the service layer signaling information and type information for identifying a type of a server providing access to the service layer signaling information or another data, and
wherein when the service layer signaling information is transmitted via a broadcast network, the bootstrap information includes a destination user datagram protocol (UDP) port number and a destination internet protocol (IP) address for the service layer signaling information;
parsing the low level signaling data included in the broadcast signal; and
parsing the service layer signaling information.
