Claim Text:
1. A method of transmitting a Non Real Time (NRT) service via a broadcast channel, the method comprising: generating the NRT service and signaling data, the signaling data including an NRT Information Table (NRT-IT) describing one or more content items and a Service Map Table (SMT) containing service-level attributes for the NRT service, wherein the SMT includes information used as a linkage to the NRT-IT; and transmitting the NRT service and the signaling data via a broadcast channel, wherein the signaling data is transmitted via a Service Signaling Channel (SSC) with a specific IP address and UDP port number, wherein the non-real time 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, wherein a service type of 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, wherein each of the FLUTE file delivery sessions includes one or more FLUTE channels, and wherein the SMT describes one or more NRT services and wherein the NRT-IT provides descriptive metadata about the content items that make up the NRT service and includes information being used to map one or more files carried on the FLUTE file delivery sessions for the non-real time service to content items, wherein the NRT-IT includes information indicating a total size in bytes of the content items.
