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 the conditions present at the time of capture of the audio information, environmental conditions. The environmental conditions may include one or more of day, date, time, location, network, motion, orientation, etc. 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. The system can identify conditions present at the time of capture of an audio signature that is an acceptable match to a reference audio signature and use the identified conditions to determine conditions under which the system will capture audio content and generate audio signatures.

Claims

1. An apparatus for monitoring audio information comprising:

a probe component to convert audio information to an electrical signal;

a probe configured to generate electrical signals indicative of conditions associated with said apparatus;

a scheduling logic unit responsive to said probe configured to generate electrical signals indicative of conditions;

an audio signature generator responsive to said probe component and

said scheduling logic unit;

a transmitter responsive to said audio signature generator.

2. An apparatus according to claim 1 wherein said probe component comprises a microphone.

3. An apparatus according to claim 1 wherein said probe configured to generate signals indicative of conditions is configured to generate signals indicative of motion.

4. An apparatus according to claim 1 wherein said probe configured to generate signals indicative of conditions is configured to generate signals indicative of time.

5. An apparatus according to claim 1 wherein said probe configured to generate signals indicative of conditions is configured to generate signals indicative of time of day.

6. An apparatus according to claim 1 wherein said probe configured to generate signals indicative of conditions is configured to generate signals indicative of location.

7. An apparatus according to claim 1 wherein said probe configured to generate signals indicative of conditions is configured to generate signals indicative of network connection.

8. An apparatus according to claim 1 further comprising a time delay element associated with said scheduling logic unit.

9. A method for monitoring audio information comprising the steps of:

capturing environmental conditions;

determining if environmental conditions satisfy a scheduling rule capturing audio information;

generating and audio signature from captured audio information based on the result of the step of determining.

10. A method according to claim 9 further comprising the step of storing said environmental conditions in a database.

11. A method according to claim 9 further comprising the step of receiving a flag correlated to one or more of said environmental conditions.

12. A method according to claim 9 further comprising the step of generating a scheduling rule on the basis of the environmental condition that one or more of said flags are correlated to.

13. A method according to claim 9 further comprising the step of transmitting said audio signature.

14. A method for automated content recognition comprising the steps of:

receiving an audio signature;

comparing said audio signature to one or more reference audio signatures;

generating a signal indicative of the result of the step of comparing.

15. A method according to claim 14 wherein the step of generating a signal further comprises the step of generating a signal indicative of recognition of said audio signature correlated to a recognized signature.

16. A method according to claim 15 further comprising the step of transmitting said signal indicative of recognition of said audio signature and an identification of said recognized signature.
