Abstract

An apparatus and method of adding thin client functionality are disclosed. One example method provides generating a call function directed to an electronic device and at least one peripheral device. The method also includes redirecting the call function to an auxiliary device, extracting payload data from information sent to the at least one peripheral device, discarding values outside a previously negotiated range from the extracted payload data, performing at least one of incrementing and decrementing the remaining values of the payload data to create a data subset, and redirecting the data subset to at least one other peripheral device resulting in output information being sent to the at least one other peripheral device.

Claims

1. A method of adding thin client functionality to an electronic device, the method comprising:

generating a call function directed to the electronic device and at least one peripheral device;

redirecting the call function to an auxiliary device;

extracting payload data from information sent to the at least one peripheral device;

discarding values outside a previously negotiated range from the extracted payload data;

performing at least one of incrementing and decrementing the remaining values of the payload data to create a data subset;

processing information sent to the electronic device via at least two filters each of which comprises at least one of a high-pass filter, a low-pass filter and a band-pass filter; and

redirecting the data subset to at least one other peripheral device resulting in output information being sent to the at least one other peripheral device.

2. The method of claim 1, wherein redirecting the call function to an auxiliary device includes preserving the original call function.

3. The method of claim 1, wherein the at least two filters are inverses of each other.

4. The method of claim 1, wherein the information sent to the electronic device is processed by at least one of the at least two filters before it is passed to the electronic device.

5. The method of claim 1, wherein the thin client functionality provides a communication medium with peripheral devices which include at least one of a keyboard, mouse, speaker, modem, display.

6. An electronic device configured to add thin client functionality, the electronic device comprising:

a processor configured to

generate a call function directed to the electronic device and at least one peripheral device,

redirect the call function to an auxiliary device,

extract payload data from information sent to the at least one peripheral device,

discard values outside a previously negotiated range from the extracted payload data,

perform at least one of incrementing and decrementing the remaining values of the payload data to create a data subset;

process received information via at least two filters each of which comprises at least one of a high-pass filter, a low-pass filter and a band-pass filter; and

a transmitter configured to redirect the data subset to at least one other peripheral device resulting in output information being sent to the at least one other peripheral device.

7. The apparatus of claim 6, wherein redirecting the call function to an auxiliary device includes preserving the original call function.

8. The apparatus of claim 6, wherein the at least two filters are inverses of each other.

9. The apparatus of claim 6, wherein the information sent to the electronic device is processed by at least one of the at least two filters before it is passed to the electronic device.

10. The apparatus of claim 6, wherein the thin client functionality provides a communication medium with peripheral devices which include at least one of a keyboard, mouse, speaker, modem, display.

11. A non-transitory computer storage medium configured to store a computer program that when executed causes a processor to perform adding thin client functionality to an electronic device, the processor being further configured to perform:

generating a call function directed to the electronic device and at least one peripheral device;

redirecting the call function to an auxiliary device;

extracting payload data from information sent to the at least one peripheral device;

discarding values outside a previously negotiated range from the extracted payload data;

performing at least one of incrementing and decrementing the remaining values of the payload data to create a data subset;

processing information sent to the electronic device via at least two filters each of which comprises at least one of a high-pass filter, a low-pass filter and a band-pass filter; and

redirecting the data subset to at least one other peripheral device resulting in output information being sent to the at least one other peripheral device.

12. The non-transitory computer storage medium of claim 11, wherein redirecting the call function to an auxiliary device includes preserving the original call function.

13. The non-transitory computer storage medium of claim 11, wherein the at least two filters are inverses of each other.

14. The non-transitory computer storage medium of claim 11, wherein the information sent to the electronic device is processed by at least one of the at least two filters before it is passed to the electronic device.
