Abstract

According to the present invention, a method for receiving a broadcast service comprises the steps of: selecting a non-real time service object; receiving service signaling data corresponding to the selected non-real time service object; determining a consumption model of the non-real time service object on the basis of the service signaling data; acquiring, if the consumption model is a predetermined consumption model, first content item reception information contained in the non-real time service object from the service signaling data; receiving a first content item on the basis of the first content item reception information; and executing the first content item in response to a request for execution from the selected non-real time service object.

Claims

1. A method for a broadcast receiving device to receive a broadcast, comprising:

receiving an uncompressed broadcast content from a broadcaster;

extracting characteristic information from a frame of the uncompressed broadcast content;

receiving a response including a timestamp of the frame of the uncompressed broadcast content and location information on a server;

receiving a trigger from the server by using the location information,

wherein the trigger includes an identifier for identifying a triggered declarative object (TDO), a trigger time indicating a timing for activating the TDO, and a trigger action indicating a state of the TDO;

generating a command for the TDO based on the trigger, wherein the command only includes the trigger action; and

transmitting the command for the TDO to a second screen device at a specific time designated by the trigger time,

wherein the second screen device acts on the command for the TDO.

2. The method of claim 1, further comprising:

receiving a TDO information on the TDO,

wherein the TDO information includes the trigger action,

wherein the command for the TDO includes the trigger action,

wherein allowed values for the trigger action include a preparation, an execution, a suspension, and a termination.

3. The method of claim 2, wherein the TDO information includes a target device type for the TDO,

wherein a value of the target device type represents one of the broadcast receiving device and the second screen device.

4. The method of claim 3, wherein the command for the TDO includes the target device type for the TDO.

5. The method of claim 1, further comprising:

receiving a capabilities descriptor which provides a list of capabilities used for the TDO,

wherein the generating the command for the TDO based on the trigger and the TDO information comprises;

generating the command for the TDO based on the capabilities descriptor,

wherein a value of capability category code in the capabilities descriptor represents one of a download protocol, an FEC algorithm, wrapper/archive formats, compression algorithms, and a media type.

6. The method of claim 2, wherein the TDO information includes a URL which is used for downloading a file which is part of the TDO,

wherein the command for the TDO includes the URL.

7. The method of claim 1, further comprising:

receiving a subscription request from the second screen device,

wherein the transmitting the command for the TDO to the second screen device comprises;

transmitting the command for the TDO based on the subscription request.

8. An apparatus for receiving a broadcast service, comprising:

a trigger processor for receiving an uncompressed broadcast content from a broadcaster;

a service manager for extracting characteristic information from a frame of the uncompressed broadcast content, and generating a command for a triggered declarative object (TDO) based on a trigger,

wherein the command only includes a trigger action; and

a network interface for transmitting the command for the TDO to a second screen device at a specific time designated by the trigger time,

wherein a receiving unit receives a response including a timestamp of the frame of the broadcast content and location information on a server, and receives the trigger from the server by using the location information,

wherein the trigger includes an identifier for identifying the TDO, a trigger time indicating a timing for activating the TDO, and a trigger action indicating a state of the TDO,

wherein the second screen device acts on the command for the TDO.

9. The apparatus of claim 8,

wherein the receiving unit receives a TDO information on the TDO,

wherein the TDO information includes the trigger action,

wherein the command for the TDO includes the trigger action,

wherein allowed values for the trigger action include a preparation, an execution, a suspension, and a termination.

10. The apparatus of claim 9, wherein the TDO information includes a target device type for the TDO,

wherein a value of the target device type represents one of the broadcast receiving device and the second screen device.

11. The apparatus of claim 8, wherein the trigger processor receives a capabilities descriptor which provides a list of capabilities used for the TDO,

wherein the service manager generates the command for the TDO based on the capabilities descriptor,

wherein a value of capability category code in the capabilities descriptor represents one of a download protocol, an FEC algorithm, wrapper/archive formats, compression algorithms, and a media type.

12. The apparatus of claim 8, wherein the TDO information includes a URL which is used for downloading a file which is part of the TDO,

wherein the command for the TDO includes the URL.

13. The apparatus of claim 8, wherein the trigger processor receives a subscription request from the second screen device,

wherein the network interface transmits the command for the TDO based on the subscription request.
