Claim:
1. A method of transmitting a non-real time (NRT) service, the method comprising: generating data for the NRT service that is delivered in advance of its use; generating signaling data for signaling services including the NRT service; and transmitting a broadcast signal including the generated data and the generated signaling data, wherein the generated signaling data includes signaling information and NRT signaling information, wherein the NRT signaling information is related to delivery of the generated data, wherein the NRT signaling information is carried based on a User Datagram Protocol/Internet Protocol (UDP/IP) method, wherein the generated data is delivered through a file delivery session based on Layered Coding Transport (LCT) protocol upon a UDP/IP protocol in the broadcast signal, wherein the NRT signaling information includes a transmission session identifier, a start time, an end time and bandwidth information for the transmission session, wherein the bandwidth information is specified by using an Application Specific bandwidth and represents a maximum bit-rate required by the transmission session, and wherein the signaling information includes service category information identifying the NRT service, hidden information indicating that the NRT service is not intended to be selected and signaling channel information for carrying the NRT signaling information.
