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, the IP packets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT), wherein the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format, and

wherein a Receiver Targeting Descriptor is included in at least one of SMT and NRT-IT and downloading the NRT service when the NRT service is valid based on a targeting_criterion_type_code included in the Receiver Targeting Descriptor.

2. 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.

3. 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.

4. The method of claim 2, wherein the targeting_criterion_type_code field is a 5-bit field.

5. The method of claim 1, wherein the SSC is carried in a portion of the IP packets.

6. The method of claim 5, wherein the SMT is linked to the NRT-IT and carried through the SSC, the SMT describing one or more NRT services, and the NRT-IT providing descriptive metadata about the content items that make up the NRT service.

7. The method of claim 1, wherein the Receiver Targeting Descriptor is included in at least one of descriptor loop of the NRT service in the SMT or in descriptor loop of a content item in the NRT-IT.

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

a tuner 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 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, the IP packets associated with a virtual channel are identified by references in a Virtual Channel Table (VCT) and an associated Program Map Table (PMT), wherein the IP packets are carried in MPEG-2 Transport Stream using Digital Storage Media Command and Control (DSM-CC) Addressable Section format, and

wherein a Receiver Targeting Descriptor is included in at least one of SMT and NRT-IT and downloading the NRT service when the NRT service is valid based on a targeting_criterion_type_code included in the Receiver Targeting Descriptor.

9. The apparatus of claim 8, wherein the targeting_criterion_type_code indicates a location or a target age group included in the Receiver Targeting Descriptor.

10. The apparatus of claim 8, wherein the receiver is updated by requesting a user to input a new targeting_criterion_type_code and its value.

11. The apparatus of claim 9, wherein the targeting_criterion_type_code field is a 5-bit field.

12. The apparatus of claim 8, wherein the SSC is carried in a portion of the IP packets.

13. The apparatus of claim 12, wherein the SMT is linked to the NRT-IT and carried through the SSC, the SMT describing one or more NRT services, and the NRT-IT providing descriptive metadata about the content items that make up the NRT service.

14. The apparatus of claim 8, wherein the Receiver Targeting Descriptor is included in at least one of descriptor loop of the NRT service in the SMT or in descriptor loop of a content item in the NRT-IT.
