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.

Claims

1. A method of receiving a broadcast signal in a receiver, the method comprising:

receiving the broadcast signal including Internet Protocol (IP)/User Datagram Protocol (UDP) packets carrying data for a service and singling data including first signaling data and second signaling data,

wherein the service is a file-based broadcast service,

wherein the file-based broadcast service includes one or more content items,

wherein the one or more content items are delivered via a file transmission session over the IP/UDP packets,

wherein the first signaling data includes service category information for identifying that a category of the service is the file-based broadcast service, service identification information for identifying the file-based broadcast service, status information for identifying whether the file-based broadcast service is hidden, and short name information of the file-based broadcast service, and

wherein the second signaling data includes information for a start time of the file transmission session and an end time of the file transmission session;

demodulating the received broadcast signal;

de-capsulating the IP/UDP packets in the demodulated broadcast signal; and

processing the one or more content items in the de-capsulated IP/UDP packets based on the second signaling data.

2. An apparatus for receiving a broadcast signal, the apparatus comprising:

a tuner that receives the broadcast signal including Internet Protocol (IP)/User Datagram Protocol (UDP) packets carrying data for a service and singling data, the signaling data including first signaling data and second signaling data,

wherein the service is a file-based broadcast service,

wherein the file-based broadcast service includes one or more content items,

wherein the one or more content items is delivered via a file transmission session over the IP/UDP packets,

wherein the first signaling data includes service category information for identifying that a category of the service is the file-based broadcast service, service identification information for identifying the file-based broadcast service, status information for identifying whether the file-based broadcast service is hidden, and short name information of the file-based broadcast service, and

wherein the second signaling data includes information for a start time of the file transmission session and an end time of the file transmission session;

a demodulator that demodulates the received broadcast signal;

a parser that de-capsuates the IP/UDP packets in the demodulated broadcast signal; and

an engine that process the one or more content items in the de-capsulated IP/UDP packets based on the second signaling data.
