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;

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; and

an embedding hardware unit configured to embed the user response signal with third-party information for purposes of revenue sharing between a plurality of third parties.

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 output mechanism comprises a transmitter and an antenna, and wherein the communications link comprises wireless communication.

6. The system of claim 1, wherein the entity is a content provider.

7. The system of claim 5, wherein the user response signal comprises a user'"'"'s purchasing selection related to the extracted hidden data.

8. The system of claim 7, wherein the embedding unit is configured to embed the user response signal with identification information associated with the system.

9. The system of claim 8, wherein the identification information associated with the system is a serial number of the system.

10. The system of claim 8, wherein the identification information facilitates allocation of revenue generated from the user'"'"'s purchasing selection.

11. 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;

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; and

an embedding hardware unit configured to embed the user response signal with third-party information for purposes of revenue sharing between a plurality of third parties.

12. The system of claim 11, wherein the embedding unit 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.

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

14. 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;

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

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

prior to transmitting, embedding the user response signal with third-party information for purposes of revenue sharing between a plurality of third parties.

15. The method of claim 14, 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.

16. A hardware processor configured to:

receive a radio frequency signal comprising hidden data;

extract the hidden data upon instruction from a user interface;

display the hidden data upon said extraction;

select a representative portion of the extracted hidden data for display;

establish a communications link with an entity associated with the hidden data;

transmit a user response signal indicative of a user'"'"'s response to the displayed hidden data from a user device to the entity; and

embed the user response signal with third-party information for purposes of revenue sharing between a plurality of third parties.

17. The hardware processor of claim 16, further configured to embed the user response signal with identification information associated with the system, 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.

18. A non-transitory program storage medium having computer executable instructions stored thereon, which when executed perform the following:

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;

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

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

prior to transmitting, embedding the user response signal with third-party information for purposes of revenue sharing between a plurality of third parties.

19. The non-transitory medium of claim 18, further performing the steps of 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.
