Method for mapping signaling information to announcement information and broadcast receiver
First Claim
1. A method of receiving a non-real time service, the method comprising:
- receiving, at a reception unit, a broadcast signal including a transmission frame conveying the non-real time service;
demodulating, at a demodulator, the received broadcast signal; and
obtaining, at a decoder, the transmission frame including internet protocol (IP) datagrams and signaling data in the demodulated signal, the IP datagrams 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 services and second signaling data,wherein the first signaling data includes service category information identifying the non-real time service, IP addresses and UDP ports,wherein each of the 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 has a same IP address and consecutively numbered UDP ports signaled with a single component descriptor in the first signaling data, andwherein the second signaling data includes a content fragment, the content fragment containing information identifying the one or more content items and used to map the one or more files delivered via the FLUTE file delivery sessions for the non-real time service to the one or more content items.

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.
