1. A method of transmitting a broadcast signal for a Non-Real Time (NRT) service, the method comprising:
- generating the broadcast signal including the NRT service that is delivered in advance of its use and stored in a receiving device, and signaling data including an NRT Information Table (NRT-IT) describing one or more content items available for download to storage in the receiving device for signaling NRT service and signaling data further including a Service Map Table (SMT) containing service-level attributes for the NRT broadcasting, wherein the SMT includes information used as a linkage to the NRT-IT; and
transmitting the NRT service via a broadcast channel and the signaling data via a Service Signaling Channel (SSC) with a specific IP address and UDP port number,wherein the NRT service includes one or more content items, each of the one or more content items composed of one or more files delivered via File Delivery over Unidirectional Transport (FLUTE) file delivery sessions,wherein, the NRT service is delivered within IP packets, the IP packets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT), wherein the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format,wherein the NRT service includes at least one of a portal service and a push service,wherein the portal service is a type of the NRT service to browse an internet using a web browser, andwherein the NRT-IT includes first information identifying the content items and being used to map one or more files carried on the FLUTE file delivery sessions for the non-real time service to content items.
