Receiving device, receiving method, transmitting device, and transmitting method for controlling applications

1. A receiving device comprising:

a receiver configured to receive broadcast content; and

circuitry configured to

acquire trigger information for identifying a command to control an operation of an application program that is run in conjunction with the broadcast content;

acquire a correspondence table in which the command is associated with information for identifying the command; and

control operations of a subject application program and another application program other than the subject application program in response to the command identified by the correspondence table, wherein the correspondence table for the subject application program includes control information indicating a time period of the subject application program and control information indicating termination of the other application program; and

wherein the control information indicating termination of the other application program does not identify the other application program, and the other application program is an application program that is being executed when the trigger information is acquired.

2. The receiving device according to claim 1 ,

wherein the command is to activate the subject application program and the same command causes stop, pause, or hiding of the another application program.

3. The receiving device according to claim 1 , wherein the circuitry is configured to

extract a feature from the broadcast content, and

acquire the trigger information corresponding to the broadcast content identified by the feature.

4. The receiving device according to claim 1 ,

wherein the command and the control information indicating the time period are associated with each other in the correspondence table, and

when a time that is determined based on the trigger information and that indicates progression of the broadcast content is within the time period indicated by the control information, the circuitry controls the operations of the subject application program and the another application program in response to the command associated with the control information indicating the time period.

5. The receiving device according to claim 1 ,

wherein an identifier of the command is further associated in the correspondence table, and

when the identifier of the command obtained from the trigger information corresponds with the identifier of the command associated in the correspondence table, the circuitry controls the operations of the subject application program and the another application program in response to the command associated with the identifier.

6. The receiving device according to claim 1 , wherein the circuitry is further configured to acquire the subject application program separately from the broadcast content and the correspondence table.

7. A receiving method of a receiving device, the method executed by the receiving device, comprising:

receiving broadcast content; and

acquiring trigger information for identifying a command to control an operation of an application program that is run in conjunction with die broadcast content;

acquiring a correspondence table in which the command is associated with information for identifying the command; and

controlling operations of a subject application program and another application program other than the subject application program in response to the command identified by the correspondence table,

wherein the correspondence table for the subject application program includes control information indicating a time period of the subject application program and control information indicating termination of the other application program; and

wherein the control information indicating termination of the other application program does not identify the other application program, and the other application program is an application program that is being executed when the trigger information is acquired.

8. The receiving method according to claim 7 ,

wherein the command is to activate the subject application program and the same command causes stop, pause, or hiding of the another application program.

9. The receiving method according to claim 7 , further comprising

extracting a feature from the broadcast content, and

acquiring the trigger information corresponding to the broadcast content identified by the feature.

10. The receiving method according to claim 7 ,

wherein the command and the control information indicating the time period are associated with each other in the correspondence table, and

the method further comprises, when a time that is determined based on the trigger information and that indicates progression of the broadcast content is within the time period indicated by the control information, controlling the operations of the subject application program and the another application program in response to the command associated with the control information indicating the time period.

11. The receiving method according to claim 7 ,

wherein an identifier of the command is further associated in the correspondence table, and

the method further comprises, when the identifier of the command obtained from the trigger information corresponds with the identifier of the command associated in the correspondence table, controlling the operations of the subject application program and the another application program in response to the command associated with the identifier.

12. The receiving method according to claim 7 , wherein the method further comprises acquiring the subject application program separately from the broadcast content and the correspondence table.

13. A non-transitory computer-readable storage medium storing computer-readable instructions thereon, which, when executed by a receiving device, cause the receiving device to perform a method comprising:

receiving broadcast content; and

acquiring trigger information for identifying a command to control an operation of an application program that is run in conjunction with the broadcast content;

acquiring a correspondence table in which the command is associated with information for identifying the command; and

controlling operations of a subject application program and another application program other than the subject application program in response to the command identified by the correspondence table,

wherein the correspondence table for the subject application program includes control information indicating a time period of the subject application program and control information indicating termination of the other application program; and

wherein the control information indicating termination of the other application program does not identify the other application program, and the other application program is an application program that is being executed when the trigger information is acquired.

14. The non-transitory computer-readable storage medium according to claim 13 ,

wherein the command is to activate the subject application program and the same command causes stop, pause, or hiding of the another application program.

15. The non-transitory computer-readable storage medium according to claim 13 , further comprising

extracting a feature from the broadcast content, and

acquiring the trigger information corresponding to the broadcast content identified by the feature.

16. The non-transitory computer-readable storage medium according to claim 13 ,

wherein the command and the control information indicating the time period are associated with each other in the correspondence table, and

the method further comprises, when a time that is determined based on the trigger information and that indicates progression of the broadcast content is within the time period indicated by the control information, controlling the operations of the subject application program and the another application program in response to the command associated with the control information indicating the time period.

17. The non-transitory computer-readable storage medium according to claim 13 , wherein an identifier of the command is further associated in the correspondence table, and

the method further comprises, when the identifier of the command obtained from die trigger information corresponds with the identifier of the command associated in the correspondence table, controlling the operations of the subject application program and the another application program in response to the command associated with the identifier.

18. The non-transitory computer-readable storage medium according to claim 13 , wherein the method further comprises acquiring the subject application program separately from die broadcast content and the correspondence table.
