Reception device, reception method, program, and information processing system
First Claim
1. A reception device comprising:
- a receiver to receive AV content;
processing circuitry to;
extract a first fingerprint feature value from one or both of an audio signal and a video signal of the received AV content;
acquire an identification result of the AV content identified using the extracted first fingerprint feature value;
acquire 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, the application program controls displaying data of the application program superimposed on the received AV content on a display;
control the operation of the application program according to the acquired command; and
a detector to detect switching of the AV content being viewed,wherein, when the switching of the AV content is detected, the processing circuitry extracts a second fingerprint feature value from one or both of the audio signal and the video signal, and when the second fingerprint feature value does not match the first fingerprint feature value, confirms that the AV content has been switched, and the processing circuitry forcibly closes the application program that has been executed in linkage with the AV content.

Abstract
Provided is a reception device including 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 acquire an identification result of the AV content identified using the extracted feature value, a command acquisition unit configured to acquire 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, a control unit configured to control the operation of the application program according to the acquired command, and a detection unit configured to detect switching of the AV content being viewed. 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.

12. An information processing system comprising:
-
a receiver to receive AV content; a first information processing circuitry; a second information processing circuitry; and a third information processing circuitry, wherein the receiver includes processing circuitry to; extract a first fingerprint feature value from one or both of an audio signal and a video signal of the received AV content, transmit the extracted first fingerprint feature value to the first information processing circuitry and to thereby acquire an identification result of the AV content identified by the first information processing circuitry using the first fingerprint feature value, transmit the identification result acquired from the first information processing circuitry to the second information processing circuitry and to thereby acquire, from the second information processing circuitry, a command for controlling an operation of an application program that is executed in linkage with the AV content according to the identification result, the application program controls displaying data of the application program superimposed on the received AV content on a display, control the operation of the application program that is acquired from the third information processing circuitry according to the command acquired from the second information processing circuitry, and a detector to detect switching of the AV content being viewed, wherein, when the switching of the AV content is detected, the processing circuitry extracts a second fingerprint feature value from one or both of the audio signal and the video signal, and when the second fingerprint feature value does not match the first fingerprint feature value, confirms that the AV content has been switched, and the processing circuitry closes the application program that has been executed in linkage with the AV content, wherein the first information processing circuitry provides the identification result obtained by identifying the AV content using the first fingerprint feature value in response to an inquiry from the receiver, wherein the second information processing circuitry provides the command according to the identification result in response to an inquiry from the receiver, and wherein the third information processing circuitry provides the application program according to the command in response to an inquiry from the receiver.
