Abstract

A plurality of audio signals are broadcasted concurrently on a plurality of substantially separate audio channels. Each of the audio channels has a center frequency greater than approximately 16 kHz. Broadcasting the audio signals causes one or more clients to automatically retrieve a resource from a resource location. The plurality of audio signals collectively encode a resource identifier that describes the resource location.

Claims

1. A method comprising:

broadcasting a plurality of audio signals concurrently on a plurality of substantially separate audio channels, each of the audio channels having a center frequency being greater than approximately 16 kHz, thereby causing one or more clients to automatically retrieve a resource from a resource location, wherein the plurality of audio signals collectively encode a resource identifier that describes the resource location.

2. The method of claim 1, wherein the resource includes multimedia content.

3. The method of claim 1, wherein the resource includes source code or executable code.

4. The method of claim 1, wherein the resource location includes a Uniform Resource Locator.

5. The method of claim 1, wherein the resource location includes an Internet Protocol address.

6. The method of claim 1, wherein the resource location includes a path on a storage medium.

7. The method of claim 1, wherein the resource location includes a memory address.

8. The method of claim 1, wherein each of the audio channels has a center frequency greater than 16 kHz.

9. The method of claim 1, wherein the plurality of audio channels are separate.

10. The method of claim 1, further comprising:

receiving the resource identifier;

segmenting the identifier into a plurality of parts; and

encoding each one of the plurality of parts, thereby producing the plurality of audio signals.

11. The method of claim 10, wherein encoding includes encoding using a Gaussian Minimum Shift Keying technique.

12. The method of claim 10, further comprising identifying a minimum channel size and a total usable bandwidth, wherein the identifier is segmented into a number of parts equal to the total usable bandwidth divided by the minimum channel size.

13. The method of claim 10, wherein the identifier is segmented into three parts.

14. The method of claim 10, wherein the resource identifier includes an integer between 0 and 2̂

30.

15. The method of claim 14, wherein the resource identifier consists of an integer between 0 and 2̂

30.

16. A method comprising:

receiving a resource identifier;

segmenting the identifier into a plurality of parts;

encoding each one of the plurality of parts, thereby producing a plurality of encoded signals;

modulating each one of the plurality of encoded signals onto a plurality of audio channels, each one of the plurality audio channels having a center frequency greater than about 16 kHz and each one of the plurality of audio channels having a center frequency substantially different from each other one of the plurality of audio channels; and

broadcasting the plurality of encoded signals concurrently on the plurality of audio channels.

17. The method of claim 16, further comprising receiving and decoding the resource identifier.

18. The method of claim 16, wherein each one of the plurality audio channels having a center frequency separated from each other one of the plurality of channels by at least 1.5 kHz.

19. The method of claim 16, wherein broadcasting includes transmitting from a presenter to an audience at a presentation.

20. The method of claim 16, wherein broadcasting includes transmitting from a location in a retail venue.
