## Abstract

A broadcast signal reception method and a reception system are provided. The reception system includes a first processor, a second processor, and a storage medium. The first processor receives and processes a signaling table, the signaling table comprising first signaling information including access information of Non-Real-Time (NRT) service data and second signaling information including media object association information of the NRT service data. The second processor receives the NRT service data and processes a file including the received NRT service data based on the access information and the media object association information processed by the first processor. The storage medium stores the processed file of the NRT service data.

## Claims

### Claim 1

A method of transmitting a broadcast signal for a non-real-time (NRT) service, the method comprising:
generating the NRT service that is a broadcast service delivered in advance of its use, the NRT service including NRT content;
generating signaling data for signaling the NRT service; and
transmitting the NRT service and the signaling data,
wherein the signaling data is transmitted via a signaling path with a specific Internet Protocol (IP) address,
wherein the signaling data includes an information table including information for service acquisition for broadcast services,
wherein the NRT content is segmented into files that are delivered in at least one file delivery session,
wherein the information table further includes service category information specifying a category of the broadcast service,
wherein the information table further includes protection information indicating whether one or more components needed for presentation of the NRT service are protected,
wherein the information table further includes service identification information identifying the broadcast service, and
wherein the information table further includes short service name information indicating a short name of the broadcast service.

### Claim 2

A method for receiving a broadcast signal for a non-real-time (NRT) service, the apparatus comprising:
receiving the NRT service that is a broadcast service delivered in advance of its use, the NRT service including NRT content;
receiving signaling data for signaling the NRT service, the signaling data received via a signaling path with a specific Internet Protocol (IP) address;
parsing an information table from the received signaling data, the information table including information for service acquisition for broadcast services,
obtaining service category information specifying a category of the broadcast service from the parsed information table;
obtaining protection information from the parsed information table, the protection information indicating whether one or more components needed for presentation of the NRT service are protected;
obtaining service identification information from the parsed information table, the service identification information identifying the broadcast service;
obtaining short service name information from the parsed information table, the service name information indicating a short name of the broadcast service; and
storing the NRT content,
wherein the NRT content is segmented into files that are delivered in at least one file delivery session.

### Claim 3

An apparatus for receiving a broadcast signal for a non-real-time (NRT) service, the apparatus comprising:
a tuner that receives the NRT service that is a broadcast service delivered in advance of its use and receives signaling data for signaling the NRT service, the NRT service including NRT content; and
a storage unit that stores information,
wherein the signaling data is transmitted via a signaling path with a specific Internet Protocol (IP) address;
a processor that:
parses an information table from the received signaling data, the information table including information for service acquisition for broadcast services,
obtains service category information specifying a category of the broadcast service from the parsed information table;
obtains protection information from the parsed information table, the protection information indicating whether one or more components needed for presentation of the NRT service are protected;
obtains service identification information from the parsed information table, the service identification information identifying the broadcast service;
obtains short service name information from the parsed information table, the service name information indicating a short name of the broadcast; and
stores the NRT content in the storage unit,
wherein the NRT content is segmented into files that are delivered in at least one file delivery session.
