Patent ID: 8537746

Claim:
A method of transmitting a non-real time service, the method comprising: generating Reed-Solomon (RS) frames that include internet protocol (IP) datagrams containing the non-real time service that is delivered in advance of its use and stored in a receiving device and signaling data for the non-real time service; modulating data for the RS frames using a Vestigial Side Band (VSB) method; and transmitting a broadcast signal including the modulated data via a broadcast channel, wherein the IP datagrams are encapsulated based on a User Datagram Protocol/Internet Protocol (UDP/IP) method, wherein the non-real time service includes one or more content items, each of the one or more content items comprising one or more files delivered via File Delivery over Unidirectional Transport (FLUTE) file delivery sessions, wherein the signaling data includes first signaling data containing service-level attributes for the non-real time service and second signaling data for configuring a service guide comprising a content fragment that carries a first element identifying a content item of the one or more content items, wherein the first signaling data further contains service category information identifying the non-real time service and IP addresses, UDP ports and Transport Session Identifiers (TSIs) of the FLUTE file delivery sessions, wherein each of FLUTE file delivery sessions includes one or more FLUTE channels, wherein all of the one or more 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 first signaling data, and wherein an IP datagram carrying the first signaling data among the IP datagrams has a well-known IP address and UDP port number.
