Abstract

A system and method for enabling a user to retrieve, decode, and utilize hidden data embedded in audio signals. An exemplary implementation includes a microphone structured to receive sound waves representative of an audio signal and hidden data embedded in the audio signal. The then microphone converts the received sound waves into an electrical output signal. The system also includes a processor electrically coupled to the microphone and configured to receive the electrical output signal in order to extract the hidden data and provide information represented by the hidden data as an output thereof. A user interface is also provided and is electrically coupled to the processor and configured to receive a first input from the user and activate the processor to selectively initiate extraction of the hidden data. The processor produces as an output the information represented by the hidden data. Finally, the system includes a user presentation mechanism configured to present the information to the user.

Claims

1. An electronic system, comprising:

a receiver configured to receive a radio frequency signal comprising hidden data;

a hardware processor configured to extract the hidden data;

a presentation mechanism configured to display the hidden data upon said extraction;

a software user interface configured to initiate said extraction, and select a representative portion of the extracted hidden data for display by the presentation mechanism; and

the hardware processor configured to embed the user response signal with third-party information.

2. The system of claim 1, wherein the receiver is a microphone.

3. The system of claim 1, wherein the hidden data comprises an internet uniform resource locator (URL) address.

4. The system of claim 1, wherein the presentation mechanism is a visual display that employs a menu scheme to facilitate selection of a portion of the hidden data.

5. The system of claim 1, wherein the third-party information is for purposes of revenue sharing between a plurality of third parties.

6. The system of claim 1, further comprising:

a hardware output mechanism configured to establish a communications link with an entity associated with the hidden data, and to transmit a user response signal indicative of a user'"'"'s response to the extracted hidden data displayed on the presentation mechanism.

7. The system of claim 6, wherein the output mechanism comprises a transmitter and an antenna, and wherein the communications link comprises wireless communication.

8. The system of claim 6, wherein the entity is a content provider.

9. The system of claim 1, wherein the user response signal comprises a user'"'"'s purchasing selection related to the extracted hidden data.

10. The system of claim 1, wherein the hardware processor is configured to embed the user response signal with identification information associated with the system.

11. The system of claim 10, wherein the identification information associated with the system is a serial number of the system.

12. The system of claim 10, wherein the identification information facilitates allocation of revenue generated from the user'"'"'s purchasing selection.

13. An electronic system, comprising:

a receiver configured to receive a radio frequency signal comprising hidden data;

a hardware processor configured to extract the hidden data;

a presentation mechanism configured to display the hidden data upon said extraction;

a software user interface configured to initiate said extraction, and select a representative portion of the extracted hidden data for display by the presentation mechanism; and

a hardware processor configured to embed the user response signal with third-party information.

14. The system of claim 13, wherein the third party information is for purposes of revenue sharing between a plurality of third parties.

15. The system of claim 13, further comprising:

a hardware output mechanism configured to establish a communications link with an entity associated with the hidden data, and to transmit a user response signal indicative of a user'"'"'s response to the hidden data displayed on the presentation mechanism.

16. The system of claim 13, wherein the hardware processor is configured to embed the user response signal with identification information associated with the system, and wherein the user response signal comprises a user'"'"'s purchasing selection related to the extracted hidden data.

17. The system of claim 16, wherein the identification information facilitates allocation of revenue generated from the user'"'"'s purchasing selection.

18. A method of displaying hidden data implemented by a communication device, the method comprising:

receiving a radio frequency signal comprising hidden data;

extracting the hidden data upon instruction from a user interface;

displaying the hidden data upon said extraction;

selecting a representative portion of the extracted hidden data for display; and

embedding the user response signal with third-party information.

19. The method of claim 18, further comprising:

establishing a communications link with an entity associated with the hidden data; and

transmitting a user response signal indicative of a user'"'"'s response to the displayed hidden data from a user device to the entity.

20. The method of claim 18, wherein the third party information is for purposes of revenue sharing between a plurality of third parties.

21. The method of claim 18, further comprising embedding the user response signal with identification information, wherein the user response signal comprises a user'"'"'s purchasing selection, and wherein the identification information facilitates allocation of revenue generated from the user'"'"'s purchasing selection.

22. A hardware processor configured to:
