Reception apparatus, reception method, program, and information processing system

1. A reception apparatus comprising:

a memory; and

circuitry configured to

receive audio video content,

extract trigger information for operating an application program transmitted along with said audio video content and executed in interlocked relation to said audio video content,

acquire a correspondence table for associating said trigger information with commands for controlling the operation of said application program,

store said application program and said correspondence table in said memory,

based on the stored correspondence table, determine said commands associated with the extracted trigger information, and

control the operation of said application program in response to the determined commands.

2. The reception apparatus according to claim 1 , wherein the circuitry is configured to

output said audio video content, or said audio video content as well as said application program, and

acquire said correspondence table when said audio video content being output is changed in substance.

3. The reception apparatus according to claim 2 , wherein

said trigger information includes determination information for determining an information processing apparatus providing said correspondence table or first identification information for identifying said audio video content; and

when said determination information or said first identification information included in the extracted trigger information is changed, said circuitry acquires said correspondence table from said information processing apparatus in accordance with said determination information and said first identification information.

4. The reception apparatus according to claim 3 , wherein

said correspondence table further associates said trigger information and said commands with second identification information for identifying said application program; and

said circuitry is configured to determine said commands associated with said trigger information regarding each of a plurality of application programs identified by said second identification information associated with the extracted trigger information.

5. The reception apparatus according to claim 4 , wherein said circuitry is configured to control the operation of one or a plurality of said application programs in response to the determined commands.

6. The reception apparatus according to claim 1 , wherein

said trigger information includes information indicative of the probability of said trigger information itself becoming effective; and

when said trigger information becomes effective, said circuitry controls the operation of said application program in response to said commands.

7. The reception apparatus according to claim 1 , wherein

said commands designate acquisition or registration, acquisition or activation, firing of an event, suspension, or termination of said application program; and

in response to each of said commands, said circuitry controls acquisition or registration, acquisition or activation of said application program, firing of an event into the currently executing application program, suspension, or termination of said currently executing application program.

8. A reception method for use with a reception apparatus, said reception method executing said reception apparatus to comprise:

receiving audio video content;

extracting trigger information for operating an application program transmitted along with said audio video content and executed in interlocked relation to said audio video content;

acquiring a correspondence table for associating said trigger information with commands for controlling the operation of said application program;

storing said application program and said correspondence table in a memory of said reception apparatus;

based on the stored correspondence table, determining by said reception apparatus said commands associated with the extracted trigger information; and

controlling by said reception apparatus the operation of said application program in response to the determined commands.

9. A non-transitory computer-readable storage medium storing a program which when executed by a computer causes the computer to:

receive audio video content;

extract trigger information for operating an application program transmitted along with said audio video content and executed in interlocked relation to said audio video content;

acquire a correspondence table for associating said trigger information with commands for controlling the operation of said application program;

store said application program and said correspondence table in a memory of said computer;

based on the stored correspondence table, determine by said computer said commands associated with the extracted trigger information; and

control the operation of said application program in response to the determined commands.

10. An information processing system comprising:

a reception apparatus;

a first information processing apparatus; and

a second information processing apparatus,

said reception apparatus including

a memory, and

circuitry configured to

receive audio video content,

extract trigger information for operating an application program transmitted along with said audio video content and executed in interlocked relation to said audio video content,

acquire from said first information processing apparatus a correspondence table for associating said trigger information with commands for controlling the operation of said application program,

store said application program and said correspondence table in said memory,

determine, based on the stored correspondence table, said commands associated with the extracted trigger information, and

control the operation of said application program, which is stored in said memory and acquired from said second information processing apparatus in response to the determined commands,

said first information processing apparatus including circuitry configured to

provide said correspondence table in response to a query from said reception apparatus, and

said second information processing apparatus including circuitry configured to provide said application program in response to a query from said reception apparatus.

11. The reception apparatus according to claim 1 , wherein the correspondence table associates each of a plurality of different trigger information for operating the application program with a different one of the commands.

12. The reception apparatus according to claim 1 , wherein the application program and the correspondence table are stored separately in the memory.
