Receiving device, receiving method, transmitting device, and transmitting method

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

• receiving audio/video content;
• acquiring first control information adapted to identify application control information to control operation of an application run in conjunction with the audio/video content;
• acquiring, by circuitry of a reception apparatus, a first table in which the application control information identified by the first control information is stored, the first table including an identifier associated with a specific segment of the audio/video content;
• acquire a second table when first version information that is included in second control information indicates a newer version of the first table, the first table being separate from the second table, the second table including the identifier associated with the specific segment of the audio/video content and included in the first table;
• and
• controlling, by the circuitry, the operation of the application in response to the application control information that is identified by the first control information and is stored in the first table.

A transmitting device comprising:

• a transmitter;
• and
• circuitry configured to
• generate first control information that is adapted to identify application control information to control operation of an application run in conjunction with audio/video content and includes first version information indicating a version of a first table in which the application control information identified by the first control information is stored;
• and
• transmit the first control information together with the audio/video content, wherein
• the first control information causes a reception apparatus that receives the first control information to acquire a first table in which the application control information identified by the first control information is stored, the first table including an identifier associated with a specific segment of the audio/video content, and
• second control information causes the reception apparatus to acquire a second table when second version information that is included in the second control information indicates a newer version of the first table, the first table being separate from the second table, the second table including the identifier associated with the specific segment of the audio/video content and included in the first table.

A transmitting method of a transmitting device, the method executed by the transmitting device, comprising:

• generating, by processing circuitry of the transmitting device, first control information that is adapted to identify application control information to control operation of an application run in conjunction with audio/video content and includes first version information indicating a version of a first table in which the application control information identified by the first control information is stored;
• and
• transmitting, by a transmitter of the transmitting device, the first control information together with the audio/video content, wherein
• the first control information causes a reception apparatus that receives the first control information to acquire a first table in which the application control information identified by the first control information is stored, the first table including an identifier associated with a specific segment of the audio/video content, and
• second control information causes the reception apparatus to acquire a second table when second version information that is included in the second control information indicates a newer version of the first table, the first table being separate from the second table, the second table including the identifier associated with the specific segment of the audio/video content and included in the first table.
