Abstract

A method of providing a Non-Real-Time (NRT) service includes receiving a file configuring the NRT service, first signaling information, and second signaling information in a state of being IP-packetized and contained in a single ensemble, configuring and displaying a service guide using the first signaling information acquired from the ensemble, acquiring a first content identifier of content selected from the displayed service guide, accessing a FLUTE session using the second signaling information acquired from the ensemble and acquiring a second content identifier matched with the first content identifier from the accessed FLUTE session, and receiving and storing at least one file configuring the content based on the acquired second content identifier.

First claim

What is claimed is:

1. A method of transmitting a non-real time (NRT) service, the method comprising:
generating broadcast data including data for the NRT service, data for a real-time service and signaling data; and
transmitting a broadcast signal including the broadcast data,
wherein the NRT service is delivered in advance of its use and stored in a receiving device,
wherein the broadcast data carries transport channels including service components and the signaling data,
wherein the signaling data includes access information for a transport channel for the service components,
wherein the access information includes a source Internet Protocol (IP) address for the transport channel, a destination IP address for the transport channel and a destination port for the transport channel,
wherein the signaling data and the service components, are encapsulated based on a User Datagram Protocol/IP (UDP/IP),
wherein the data for the NRT service includes one or more content items,
wherein each of the one or more content items are delivered based on Layered Coding Transport (LCT) protocol over the UDP/IP encapsulation,
wherein the signaling data further includes an identifier of a transmission session, a start time, an end time, and bandwidth information for the transmission session, and
wherein the signaling data further includes information for acquiring service guide information.

2. The method of claim 1 , wherein the signaling data further includes service category information identifying the NRT service.

3. The method of claim 1 , wherein the service guide information is complies with an Open Mobile Alliance (OMA) Broadcast Services Enabler Suite (BCAST) service guide.

4. The method of claim 3 , wherein signaling information describing one or more content items delivered in the NRT service are transmitted through fragments of the OMA BCAST service guide.
