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 transmitting a broadcast signal for a Non-Real Time (NRT) service, the method comprising:

generating the broadcast signal including the NRT service that is delivered in advance of its use and stored in a receiving device, and signaling data including an NRT Information Table (NRT-IT) describing one or more content items available for download to storage in the receiving device,

wherein the signaling data further includes a Service Map Table (SMT) containing service-level attributes for the NRT service, wherein the SMT includes information used as a linkage to the NRT-IT; and

transmitting the broadcast signal including the NRT service, and the signaling data wherein the NRT services are delivered within IP subnets, the IP subnets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT),

wherein the SMT or the NRT-IT includes a receiver targeting descriptor, and

wherein the receiver targeting descriptor includes targeting_value field containing a targeting value of any one of geographical location, alphanumeric postal code and demographic category, and targeting_criterion_type_code field specfying a type of value contained in the targeting_value field.

2. The method of claim 1, wherein the signaling data further includes a targeting criterion table which is used to define a new targeting criterion.

3. The method of claim 2, wherein the targeting criterion table includes criterion_type_text field contains a description of a targeting criterion represented by an instance of the targeting criterion table.

4. The method of claim 3, wherein the targeting criterion table further includes value_text field contains a description of the targeting value.

5. A method of receiving a broadcast signal for a Non-Real Time (NRT) service, the method comprising:

receiving the broadcast signal including the NRT service that is delivered in advance of its use and stored in a receiving device, and signaling data including an NRT Information Table (NRT-IT) describing one or more content items available for download to storage in the receiving device,

wherein the signaling data further includes a Service Map Table (SMT) containing service-level attributes for the NRT service, wherein the SMT includes information used as a linkage to the NRT-IT,

wherein the NRT services are delivered within IP subnets, the IP subnets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT);

parsing the signaling data,

wherein the SMT or the NRT-IT includes a receiver targeting descriptor, and

wherein the receiver targeting descriptor includes targeting_value field containing a targeting value of any one of geographical location, alphanumeric postal code and demographic category, and targeting_criterion_type_code field specfying a type of value contained in the targeting_value field; and

processing the one or more content items based on the signaling data.

6. The method of claim 5, wherein the signaling data further includes a targeting criterion table which is used to define a new targeting criterion.

7. The method of claim 6, wherein the targeting criterion table includes criterion_type_text field contains a description of a targeting criterion represented by an instance of the targeting criterion table.

8. The method of claim 7, wherein the targeting criterion table further includes value_text field contains a description of the targeting value.
