Media encoding using changed regions

1. A method for media encoding using changed regions, comprising:

detecting any changed regions and a static portion of a desktop of a computing device;

determining a number of changed regions, wherein a change in a pre-determined number of pixels is to indicate a changed region; and

encoding the changed regions in response to the number of changed regions being greater than a threshold number, without encoding the static portion of the desktop.

2. The method of claim 1 , comprising:

sending the changed regions and changed region position values to a composition engine;

decoding the changed regions; and

composing the changed regions with the static portion of the desktop using the changed region position values.

3. The method of claim 1 , wherein each changed region is detected when a number of changed pixels within a region is greater than a predetermined threshold.

4. The method of claim 1 , comprising:

sending the changed regions and any changed region position values to a composition engine, wherein the composition engine is located on a remote adapter; and

decoding the changed regions at the remote adapter.

5. The method of claim 1 , wherein the composition engine is located on the computing device where the changed regions and the static portion of the desktop are detected.

6. The method of claim 1 , further comprising:

detecting the changed regions by checking a back buffer;

sending the changed regions with any changed region positions to a remote adapter.

7. The method of claim 1 , comprising encoding from an I-frame in response to changed region position values not matching previous changed region position values.

8. The method of claim 1 , comprising encoding from an I-frame or a P-frame in response to changed region position values matching previous changed region position values.

9. The method of claim 1 , comprising iteratively detecting, determining, and encoding changed regions.

10. A computing device, comprising:

a detector configured to detect any changed regions and a static portion of a desktop;

a central processing unit (CPU) that is configured to execute stored instructions and a storage device that stores instructions, wherein the storage device includes processor executable code that, when executed by the CPU, is configured to:

determine a number of changed regions, wherein a change in a pre-determined number of pixels is to indicate a changed region; and

an encoder configured to encode the changed regions in response to the number of changed regions being greater than a threshold number, without encoding the static portion of the desktop.

11. The computing device of claim 10 , wherein the processor executable code, when executed by the CPU, is configured to:

send the changed regions and changed region position values to a composition engine;

decode the changed regions; and

compose the changed regions with the static portion of the desktop using the changed region position values.

12. The computing device of claim 10 , wherein each changed region is detected when a number of changed pixels within a region is greater than a predetermined threshold.

13. The computing device of claim 10 , wherein the processor executable code, when executed by the CPU, is configured to:

send the changed regions and any changed region position values to a composition engine, wherein the composition engine is located on a remote adapter; and

decode the changed regions at the remote adapter.

14. The computing device of claim 10 , further comprising a composition engine.

15. The computing device of claim 10 , wherein the computing device is configured to:

detect the changed regions by checking a back buffer;

send the changed regions with any changed region position values to a remote adapter.

16. The computing device of claim 10 , wherein the computing device is configured to encode from an I-frame in response to changed region position values not matching previous changed region position values.

17. The computing device of claim 10 , wherein the computing device is configured to encode from an I-frame or a P-frame in response to the changed region position values matching previous changed region position values.

18. The computing device of claim 10 , wherein the computing device is configured to iteratively detect, determine, and encode changed regions.

19. The computing device of claim 10 , wherein the computing device is configured to poll, push, pull, or use a timer to compose image information from a media application.

20. The computing device of claim 10 , further comprising a radio and a display, the radio and display communicatively coupled at least to the central processing unit.

21. At least one non-transitory machine readable medium having instructions stored therein that, in response to being executed on a computing device, cause the computing device to:

detect any changed regions and a static portion of a desktop of the computing device;

determine a number of changed regions, wherein a change in a pre-determined number of pixels is to indicate a changed region; and

encode the changed regions in response to the number of changed regions being greater than a threshold number, without encoding the static portion of the desktop.

22. The at least one non-transitory machine readable medium of claim 21 , having instructions stored therein that, in response to being executed on a computing device, cause the computing device to:

send the changed regions and changed region position values to a composition engine;

decode the changed regions; and

compose the changed regions with the static portion of the desktop using the changed region position values.

23. The at least one non-transitory machine readable medium of claim 21 , wherein each changed region is detected when the number of changed pixels within a region is greater than a predetermined threshold.
