Abstract

The present technique relates to a receiving device, a receiving method, a transmitting device, and a transmitting method that can satisfactorily operate an application which is executed in conjunction with AV content.
A receiving device is provided which includes: a trigger information acquiring unit that acquires trigger information including at least location information as information for controlling an operation of an application which is executed in conjunction with AV content; a metadata acquiring unit that acquires application control information for controlling the operation of the application; and an application control unit that controls the operation of the application based on the trigger information and the application control information. The present technique can be applied to, for example, a TV receiver.

First claim

1 . A receiving device comprising:
a first acquiring unit that acquires trigger information including at least location information as information for controlling an operation of an application which is executed in conjunction with audio-video (AV) content; a second acquiring unit that acquires application control information for controlling the operation of the application; and a control unit that controls the operation of the application based on the trigger information and the application control information.

2 . The receiving device according to claim 1 , wherein the trigger information includes time information serving as a reference of a time to control the operation of the application,
the second acquiring unit acquires schedule control information in which the operation of the application is prescribed in a time series, and the control unit controls the operation of the application based on action information for the application corresponding to the time when the time counted based on the time information passes through the time prescribed in the schedule control information.

3 . The receiving device according to claim 2 , wherein the application is constituted by a plurality of files,
the second acquiring unit acquires cache control information for controlling a cache of a file group constituting the application, and the control unit stores the file group constituting the application in a cache memory based on the cache control information.

4 . The receiving device according to claim 3 , wherein the trigger information includes editing information for editing details prescribed in the schedule control information, and
the control unit edits the schedule control information based on the editing information.

5 . The receiving device according to claim 4 , wherein the location information is information for acquiring the application control information, the schedule control information, and the cache control information, and
the application control information, the schedule control information, and the cache control information are correlated by identification information of the application.

6 . The receiving device according to claim 1 , wherein the trigger information includes action information for the application, and
the control unit controls the operation of the application based on the action information included in the trigger information when the trigger information is acquired.

7 . The receiving device according to claim 6 , wherein the application is constituted by a plurality of files,
the second acquiring unit acquires cache control information for controlling a cache of a file group constituting the application, and the control unit stores the file group constituting the application in a cache memory based on the cache control information.

8 . The receiving device according to claim 7 , wherein the location information is information for acquiring the application control information and the cache control information, and
the trigger information, the application control information, and the cache control information are correlated by identification information of the application.

9 . The receiving device according to claim 1 , wherein the AV content is broadcast content which is transmitted by a digital broadcast signal,
the trigger information is included in the digital broadcast signal and is distributed along with the digital broadcast signal or distributed from a server on the Internet, and the first acquiring unit acquires the trigger information which is distributed in broadcast or communication.

10 . A receiving method of a receiving device, the receiving method comprising:
acquiring trigger information including at least location information as information for controlling an operation of an application which is executed in conjunction with AV content; acquiring application control information for controlling the operation of the application; and controlling the operation of the application based on the trigger information and the application control information, the acquiring trigger information, the acquiring application control information, and the controlling the operation of the application being performed by the receiving device.

11 . A transmitting device comprising:
an acquiring unit that acquires AV content; a first generating unit that generates trigger information including at least location information as information for controlling an operation of an application which is executed in conjunction with the AV content; a second second generating unit that generates application control information for controlling the operation of the application; and a transmitter unit that transmits the trigger information and the application control information along with the AV content.

12 . The transmitting device according to claim 11 , wherein the first generating unit generates the trigger information including time information serving as a reference of a time to control the operation of the application,
the second generating unit generates schedule control information in which the operation of the application is prescribed in a time series, and the transmitter unit transmits the trigger information including the time information and the schedule control information.

13 . The transmitting device according to claim 12 , wherein the application is constituted by a plurality of files,
the second generating unit generates cache control information for controlling a cache of a file group constituting the application, and the transmitter unit additionally transmits the cache control information.

14 . The transmitting device according to claim 13 , wherein the first generating unit generates the trigger information including editing information for editing details prescribed in the schedule control information, and
the transmitter unit transmits the trigger information including the editing information.

15 . The transmitting device according to claim 14 , wherein the location information is information for acquiring the application control information, the schedule control information, and the cache control information, and
the application control information, the schedule control information, and the cache control information are correlated by identification information of the application.

16 . The transmitting device according to claim 11 , wherein the first generating unit generates the trigger information including action information for the application, and
the transmitter unit transmits the trigger information including the action information.

17 . The transmitting device according to claim 16 , wherein the application is constituted by a plurality of files,
the second generating unit generates cache control information for controlling a cache of a file group constituting the application, and the transmitter unit additionally transmits the cache control information.

18 . The transmitting device according to claim 17 , wherein the location information is information for acquiring the application control information and the cache control information, and
the trigger information, the application control information, and the cache control information are correlated by identification information of the application.

19 . The transmitting device according to claim 11 , wherein the AV content is broadcast content, and
the transmitter unit transmits the trigger information and the application control information along with the AV content using a d
