Abstract:
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, 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 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 a descriptor included in the SMT provides a reference to an image file in a File Delivery over Unidirectional Transport (FLUTE) session of the NRT service used as a service or content icon, wherein each of the FLUTE file delivery sessions includes one or more FLUTE channels, wherein all of the FLUTE channels in each of the FLUTE file delivery sessions have a same IP address and consecutively numbered UDP ports signaled with a single component descriptor in the SMT, and wherein the IP packet contains the SSC.
