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

A reception method of a reception device, the method, which is performed by the reception device, comprising the steps of:

• receiving AV content;
• extracting a feature value from data of the received AV content;
• acquiring an identification result of the AV content identified using the extracted feature value;
• acquiring a command for controlling an operation of an application program that is executed in linkage with the AV content according to the acquired identification result;
• controlling the operation of the application program according to the acquired command;
• detecting switching of the AV content being viewed;
• and
• closing the application program that has been executed in linkage with the AV content when the switching of the AV content is detected.

A program that causes a computer to execute steps of:

• receiving AV content;
• extracting a feature value from data of the received AV content;
• acquiring an identification result of the AV content identified using the extracted feature value;
• acquiring a command for controlling an operation of an application program that is executed in linkage with the AV content according to the acquired identification result;
• controlling the operation of the application program according to the acquired command;
• detecting switching of the AV content being viewed;
• and
• closing the application program that has been executed in linkage with the AV content when the switching of the AV content is detected.

An information processing system comprising:

• a reception device;
• a first information processing device;
• a second information processing device;
• and
• a third information processing device,
• wherein the reception device includes a reception unit configured to receive AV content, a feature value extraction unit configured to extract a feature value from data of the received AV content, an identification result acquisition unit configured to transmit the extracted feature value to the first information processing device and to thereby acquire an identification result of the AV content identified by the first information processing device using the feature value, a command acquisition unit configured to transmit the identification result acquired from the first information processing device to the second information processing device and to thereby acquire, from the second information processing device, a command for controlling an operation of an application program that is executed in linkage with the AV content according to the identification result, a control unit configured to control the operation of the application program that is acquired from the third information processing device according to the command acquired from the second information processing device, and a detection unit configured to detect switching of the AV content being viewed,
• wherein, when the switching of the AV content is detected, the control unit closes the application program that has been executed in linkage with the AV content,
• wherein the first information processing device includes a first providing unit configured to provide the identification result obtained by identifying the AV content using the feature value in response to an inquiry from the reception device,
• wherein the second information processing device includes a second providing unit configured to provide the command according to the identification result in response to an inquiry from the reception device, and
• wherein the third information processing device includes a third providing unit configured to provide the application program according to the command in response to an inquiry from the reception device.
