Abstract

Disclosed herein is a transmission apparatus for transmitting AV (Audio/Video) content, including: an acquirer configured to acquire an estimated number of audience terminals indicative of an estimated number of reception apparatuses receiving the AV content; a computer configured, in conjugation with the AV content, to compute, on the basis of the estimated number of audience terminals, a validity probability of trigger information associated with control of an application program to be executed in the reception apparatus; a generator configured to generate the trigger signal including the computed validity probability; and a transmitter configured to transmit the generated trigger information with the AV content.

Claims

1. (canceled)

2. A reception apparatus, comprising:

circuitry configured to

receive a plurality of triggers associated with an application program, each of a subset of the plurality of triggers including a spread parameter,

derive a time within a designated interval based on the spread parameter included in one of the subset of the plurality of triggers, and

retrieve data from a server based on location information included in the one of the subset of the plurality of triggers at the derived time.

3. The reception apparatus according to claim 2, wherein the data retrieved from the server is the application program.

4. The reception apparatus according to claim 2, wherein

the one of the subset of the plurality of triggers includes an identifier;

and

the circuitry is configured to determine an action, which is associated with the application program, to be performed based on the identifier;

5. The reception apparatus according to claim 2, wherein

each of the subset of the plurality of triggers includes a same spread parameter.

6. The reception apparatus according to claim 2, wherein

each of the subset of the plurality of triggers includes a different spread parameter.

7. A method for retrieving data, the method comprising:

receiving, by circuitry of a reception apparatus, a plurality of triggers associated with an application program, each of a subset of the plurality of triggers including a spread parameter;

deriving, by the circuitry, a time within a designated interval based on the spread parameter included in one of the subset of the plurality of triggers; and

retrieving, by the circuitry, the data from a server based on location information included in the one of the subset of the plurality of triggers at the derived time.

8. The method according to claim 7, wherein the data retrieved from the server is the application program.

9. The method according to claim 7, wherein

the one of the subset of the plurality of triggers includes an identifier, and

the method further includes determining an action, which is associated with the application program, to be performed based on the identifier;

10. The method according to claim 7, wherein

each of the subset of the plurality of triggers includes a same spread parameter.

11. The method according to claim 7, wherein

each of the subset of the plurality of triggers includes a different spread parameter.

12. A non-transitory computer-readable medium storing a program which when executed by a computer causes the computer to perform a method for retrieving data, the method comprising:

receiving a plurality of triggers associated with an application program, each of a subset of the plurality of triggers including a spread parameter;

deriving a time within a designated interval based on the spread parameter included in one of the subset of the plurality of triggers; and

retrieving the data from a server based on location information included in the one of the subset of the plurality of triggers at the derived time.
