Method for processing additional information related to an announced service or content in an NRT service and a broadcast receiver

An apparatus for receiving a broadcast signal for a Non-Real time (NRT) service, the apparatus comprising:

• a tuner configured to receive 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
• a receiving unit configured to receive 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-2Transport 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, and
• 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.
