Abstract

A method comprises encoding data by a first device, displaying the encoded data on a display of a first device, capturing an image of the encoded data displayed on the display with a camera associated with a second device, and converting the image to the data by the second device.

Claims

1. A method comprising:

encoding data by a first device;

displaying the encoded data on a display of a first device;

capturing an image of said encoded data displayed on said display with a camera associated with a second device; and

converting said image to said data by said second device.

2. The method of claim 1 further comprising converting a serial stream of said data into parallel streams of data.

3. The method of claim 2 wherein said parallel streams each contain all of said data.

4. The method of claim 2 wherein each of said parallel streams each contain a portion of said data.

5. The method of claim 1 wherein said encoding further comprises applying error correction to the encoded data.

6. The method of claim 1 wherein said displaying is carried out in a plurality of regions of said display.

7. The method of claim 1 wherein said displaying is carried out in a reserved portion of said display.

8. The method of claim 1 wherein said displaying further comprises incorporating said encoded data into content being displayed on said display.

9. The method of claim 8 wherein said encoded data cannot be perceived by a user of said display.

10. The method of claim 1 wherein said encoding provides security.

11. The method of claim 1 wherein said capturing is carried out by a digital camera.

12. The method of claim 11 wherein said camera is connected to said second device.

13. The method of claim 11 wherein said camera is integrated into said second device.

14. The method of claim 1 wherein said first device is at least one of a general purpose processor-based device, a personal digital assistant, a digital camera, a telephone, an automatic teller machine, a bill board, a panel indicator, a traffic light, and a television.

15. The method of claim 1 wherein said second device is at least one of a personal digital assistant, a digital camera, a telephone, a security camera, and a general purpose processor-based device.

16. A system for transferring data comprising:

a first device hosting data to be transferred and selectively displaying said data in an encoded format; and

a second device comprising;

an imaging device capturing an image of the encoded data displayed by said first device; and

logic for decoding said encoded data to provide said data in said second device.

17. The system of claim 16 wherein said first device comprises pixel mapping logic encoding said data.

18. The system of claim 16 wherein said first device comprises logic encoding error correction in the encoded data.

19. The system of claim 16 wherein said first device comprises logic converting a serial stream of said data into parallel streams and displaying said parallel streams of encoded data on different regions of a display screen.

20. The system of claim 19 wherein said parallel streams each contain the same encoded data, streamed at different throughput rates.

21. The system of claim 19 wherein each of said parallel streams each contain a portion of said encoded data, streamed at a same throughput rate.

22. The system of claim 16 wherein said first device is at least one of a general purpose processor-based device, a personal digital assistant, a digital camera, a telephone, an automatic teller machine, a bill board, a panel indicator, a traffic light and a television.

23. The system of claim 16 wherein said imaging device comprises a digital camera.

24. The system of claim 23 wherein said digital camera is connected to said second device.

25. The system of claim 24 wherein said second device is a general purpose processor-based device.

26. The system of claim 23 wherein said camera is integrated into said second device.

27. The system of claim 26 wherein said second device is at least one of a personal digital assistant, a digital camera, a telephone, a security camera, and a general purpose processor-based device.

28. A data transmission medium comprising:

a display displaying encoded data; and

a camera-enabled appliance adapted to capture an image of said encoded data displayed on said display for decoding.

29. A system for transferring data comprising:

means mapping select portions of data to be transferred for display in at least one encoded format;

means for displaying the encoded data according to said mapping;

means for imaging the displayed encoded data; and

means for demapping said encoded data shown in a resulting image to provide said data.
