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

transmitting the NRT service via a broadcast channel and the signaling data via a Service Signaling Channel (SSC) with a specific IP address and UDP port number, wherein;

the NRT service is delivered within IP packets forming an IP subnet, the IP subnet associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT),

the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format,

a Receiver Targeting Descriptor is included in at least one of SMT and NRT-IT,

the NRT service is downloaded based on targeting_criterion_type_code included in the Receiver Targeting Descriptor, and

the PMT includes information indicating that the SSC is contained in a program element included in the IP subnet.

2. The method of claim 1, wherein the Receiving Targeting Descriptor provides one or more targeting criterion values to indicate the receiving device to which the content item is targeted.

3. The method of claim 2, wherein the Receiving Targeting Descriptor included in the SMT is overridden for individual content items by Receiving Targeting Descriptor included in the NRT-IT.

4. The method of claim 3, wherein the Receiving Targeting Descriptor includes information indicating the number of targeting entries, each of entries having the targeting_criterion_type_code, a targeting_value_length, and a targeting_value.

5. The method of claim 4, wherein the targeting_criterion_type_code included in the Receiving Targeting Descriptor indicates any one of geographical location, alphanumeric postal code, and demographic category.

6. An apparatus for receiving a broadcast signal for a Non-Real Time (NRT) service, the apparatus comprising:

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

a second receiving unit configured to receive the NRT service via a broadcast channel and the signaling data via a Service Signaling Channel (SSC) with a specific IP address and UDP port number, wherein;

the NRT service is delivered within IP packets forming an IP subnet, the IP subnet associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT),

the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format,

a Receiver Targeting Descriptor is included in at least one of SMT and NRT-IT,

the NRT service is downloaded based on targeting_criterion_type_code included in the Receiver Targeting Descriptor, and

the PMT includes information indicating that the SSC is contained in a program element included in the IP subnet.

7. The apparatus of claim 6, wherein the Receiving Targeting Descriptor provides one or more targeting criterion values to indicate the receiving device to which the content item is targeted.

8. The apparatus of claim 7, wherein the Receiving Targeting Descriptor included in the SMT is overridden for individual content items by Receiving Targeting Descriptor included in the NRT-IT.

9. The apparatus of claim 8, wherein the Receiving Targeting Descriptor includes information indicating the number of targeting entries, each of entries having the targeting_criterion_type_code, a targeting_value_length, and a targeting_value.

10. The apparatus of claim 9, wherein the targeting_criterion_type_code included in the Receiving Targeting Descriptor indicates any one of geographical location, alphanumeric postal code, and demographic category.
