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, the NRT information providing descriptive metadata about one or more content items that make up the NRT service, the signaling data further including a service map information containing service-level attributes for the NRT broadcasting, wherein the service map information includes information used as a linkage to the NRT information; 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, wherein the service map information includes a descriptor providing a reference to an image file in a File Delivery over Unidirectional Transport (FLUTE) file delivery sessions that is used as a service or content icon, wherein the image file containing an icon image and the reference corresponds to a File Delivery Table (FDT) content linkage tag of the image file, wherein each of FLUTE file delivery sessions includes one or more FLUTE channels, and wherein all of the FLUTE channels have a same IP address and consecutively numbered UDP ports signaled with a single component descriptor in the service map information, wherein the NRT Information includes linkage information matched with one or more files in one of FLUTE file delivery sessions.
