Efficient apparatus and method for audio signature generation using motion
First Claim
Patent Images
1. An apparatus for monitoring audio information comprising:
- a probe component to capture audio information;
a motion detector;
an audio signature generator responsive to said probe component and said motion detector, wherein the audio signature generator is configured to generate audio fingerprints when the motion detector does not detect motion and to inhibit generation of audio fingerprints when the motion detector detects motion, and wherein the audio fingerprints represent audio content; and
a transmitter, responsive to the audio signal generator, that transmits the audio fingerprints over a communication channel to a remote server for potential identification of the audio content represented by the audio fingerprints.

Abstract
An automatic content recognition system that includes a user device for the purpose of capturing audio and generating an audio signature. The user device may be a smartphone or tablet. The system is also capable of determining whether a user device is in motion and refraining from audio monitoring and/or generating audio signatures when the user device is in motion. Motion may also be used to reduce the frequency of audio monitoring and/or signature generation. The system may have a database within the user device or the user device may communicate with a server having a database that contains reference audio signatures.

7. A method for monitoring audio information comprising the steps of:
-
capturing audio information by using a probe; determining if a user device is in motion by using a motion detector; generating audio fingerprints, by using an audio signal generator, from captured audio information when the user device is not in motion based on the result of the step of determining, wherein the audio fingerprints represent audio content; inhibiting the step of generating audio fingerprints when the user device is in motion based on the result of the step of determining; and transmitting audio fingerprints over a communication channel to a remote server for potential identification of the audio content represented by the audio fingerprints. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 16)
