Abstract

A method of receiving a broadcast signal including a Non-Real-Time (NRT) service and a broadcast receiver are disclosed herein. A method of receiving a broadcast signal including an NRT service, method comprises receiving a broadcast signal including first signaling information and second signaling information, identifying the NRT service based on the first signaling information, identifying an Internet Protocol (IP) address of an NRT service signaling data based on the first signaling information and the second signaling information, receiving the NRT service signaling data by accessing the IP address, and downloading a desired NRT service based on the NRT service signaling data.

Claims

1. A method of processing a service in a receiver, the method comprising:

receiving a broadcast signal including first signaling data and second signaling data related to the service;

decoding first signaling data from the broadcast signal,

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

wherein the file-based service includes at least one content item including one or more files and is delivered by a transport session, and

wherein the first signaling data is carried in Internet Protocol (IP) packets with well-known IP address information;

decoding second signaling data from the broadcast signal,

wherein the second signaling data includes information that provides a broadcast delivery schedule of the one or more files which are scheduled to be delivered during a specified period,

receiving the one or more files; and

decoding the one or more files.

2. A receiver for processing a service, the receiver comprising:

a tuner for receiving a broadcast signal including first signaling data and second signaling data related to the service;

a first signaling decoder for decoding first signaling data from the broadcast signal, wherein the first signaling data includes service information for identifying the service, service type information for identifying that a type of the service is a file-based service, status information for identifying whether the service is hidden, and short name information of the service,

wherein the file-based service includes at least one content item including one or more files and is delivered by a transport session, and

wherein the first signaling data is carried in Internet Protocol (IP) packets with well-known IP address information;

a second signaling decoder for decoding second signaling data from the broadcast signal,

wherein the second signaling data includes information that provides a broadcast delivery schedule of the one or more files which are scheduled to be delivered during a specific time period,

wherein the tuner further receives the one or more files; and

a decoder for decoding the one or more files.
