Method for receiving a broadcast signal and broadcast receiver
First Claim
1. A method of receiving a broadcast signal for a Non-Real-Time (NRT) service, the method comprising:
- receiving, by a baseband processor, a broadcast signal including first signaling information and second signaling information for the NRT service through a Service Signaling Channel (SSC) with a specific IP address, the NRT service which is delivered in advance of its use and stored in a receiving device;
identifying, by a service manager, the NRT service based on the first signaling information;
acquiring, by the service manager, an IP address of an NRT service data based on the second signaling information; and
downloading, by an NRT service manager, a desired NRT service based on the acquired IP address of the NRT service data, wherein;
the NRT service is delivered within IP packets,the IP packets are carried in Digital Storage Media Command and Control (DSM-CC) Addressable Sections in MPEG-2 Transport Stream and the DSM-CC Addressable Sections are referenced by a Virtual Channel Table (VCT) or an associated Program Map Table (PMT),the IP packets form an IP subnet, andthe PMT includes information for accessing the SSC, wherein the SSC is contained in the IP subnet.

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, the method comprises receiving a broadcast signal including first signaling information and second signaling information, identifying the NRT service based on the first signaling information, parsing the second signaling information to identify an Internet Protocol (IP) address of an NRT service signaling channel, receiving the NRT service signaling channel by accessing the IP address, and downloading a desired NRT service based on the NRT service signaling channel.

6. A broadcast receiver for receiving a broadcast signal including a Non-Real Time (NRT) service, the broadcast receiver comprising:
-
a baseband processor for receiving a broadcast signal including first signaling information and second signaling information for the NRT service through a Service Signaling Channel (SSC) with a specific IP address, the NRT service which is delivered in advance of its use and stored in a receiving device; a Service Manager for identifying the NRT service based on the first signaling information and acquiring an Internet Protocol (IP) address of an NRT service data based on the second signaling information; and an NRT service manager for downloading a desired NRT service based on the acquired IP address of the NRT service data, wherein; the NRT service is delivered within IP packets, the IP packets are carried in Digital Storage Media Command and Control (DSM-CC) Addressable Sections in MPEG-2 Transport Stream and the DSM-CC Addressable Sections are referenced by a Virtual Channel Table (VCT) or an associated Program Map Table (PMT), the IP packets form an IP subnet, and the PMT includes information for accessing the SSC, wherein the SSC is contained in the IP subnet. - View Dependent Claims (7, 8, 9, 10)
