Method for mapping signaling information to announcement information and broadcast receiver

摘要

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.

1. A method of receiving a non-real time service, the method comprising:
receiving, at a reception unit, a broadcast signal conveying the non-real time service; demodulating, at a demodulator, the received broadcast signal; obtaining, at a decoder, an internet protocol (IP) datagrams and signaling data in the demodulated signal, 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 composed of one or more files delivered via Layered Coding Transport (LCT) sessions, wherein the signaling data includes first signaling data containing service-level attributes for the non-real time services, wherein the first signaling data includes service category information identifying the non-real time service, IP addresses and UDP ports, wherein the LCT sessions include one or more channels, wherein the channels in each of the LCT sessions has a same IP address and consecutively numbered UDP ports signaled with a single component descriptor in the first signaling data.
