Abstract

A method of receiving a broadcast signal including a Non-Real-Time (NRT) Receiver Targeting service is disclosed herein. A method of receiving a broadcast signal including a Non-Real-Time (NRT) Receiver Targeting service, the method comprises receiving broadcast signal including first signaling information and second signaling information, identifying an NRT service based on the first signaling information, parsing a Receiver Targeting Descriptor from the second signaling information, determining validity of the NRT service or an NRT content based on a targeting_criterion_type_code included in the Receiver Targeting Descriptor, and downloading the NRT service or the NRT content when a receiver determines the NRT service or the NRT content to be valid.

Claims

1. A method of receiving a broadcast signal including a Non-Real-Time (NRT) Receiver Targeting service, the method comprising:

receiving a broadcast signal including first signaling information and second signaling information;

identifying an NRT service based on the first signaling information;

parsing a Receiver Targeting Descriptor from the second signaling information;

determining validity of the NRT service or an NRT content based on a targeting_criterion_type_code included in the Receiver Targeting Descriptor; and

downloading the NRT service or the NRT content when a receiver determines the NRT service or the NRT content to be valid.

2. The method of claim 1, wherein the first signaling information is a Terrestrial Virtual Channel Table (TVCT) and the second signaling information is a Non-Real-Time Service Table (NST) or a Non-Real-Time Information Table (NRT-IT).

3. The method of claim 1, wherein the Receiver Targeting Descriptor is included in a service level of an NST or a content level in an NRT-IT.

4. The method of claim 1, wherein the targeting_criterion_type_code indicates a location or a target age group included in the Receiver Targeting Descriptor.

5. The method of claim 1, wherein the receiver is updated by requesting a user to input a new targeting_criterion_type_code and its value.

6. A broadcast receiver for receiving a broadcast signal including a Non-Real-Time (NRT) Receiver Targeting service, comprising:

a baseband processor for receiving a broadcast signal including first signaling information and second signaling information;

a Program Specific Information/Program and System Information Protocol (PSI/PSIP) section parser for identifying an NRT service based on the first signaling information;

a Service Signaling Section Parser for parsing a Receiver Targeting Descriptor from the second signaling information;

a Service Manager for determining validity of the NRT service or an NRT content based on a targeting_criterion_type_code included in the Receiver Targeting Descriptor; and

an NRT service manager for downloading the NRT service or the NRT content when the receiver determines the NRT service or the NRT content to be valid.

7. The broadcast receiver of claim 6, wherein the first signaling information is a Terrestrial Virtual Channel Table (TVCT) and the second signaling information is a Non-Real-Time Service Table (NST) or a Non-Real-Time Information Table (NRT-IT).

8. The broadcast receiver of claim 6, wherein the Receiver Targeting Descriptor is included in a service level of an NST or a content level in an NRT-IT.

9. The broadcast receiver of claim 6, wherein the targeting_criterion_type_code indicates a location or a target age group included in the Receiver Targeting Descriptor.
