Abstract

A system and method are provided for dynamically selecting one or more modules of a graphics processor for processing content to support communication of the content over a wireless network link for subsequent display of the content utilizing a display.

Claims

1. A method, comprising:

receiving content at a graphics processor including a plurality of modules; and

dynamically selecting one or more of the modules of the graphics processor for processing the content to support communication over a wireless network link and subsequent displaying of the content utilizing a display;

wherein the processing includes preparing the content for transmission over the wireless network link;

wherein in response to detection by a transmitter utilized for transmitting the content over the wireless network link of a change in available bandwidth of the wireless network link, the transmitter instructs at least one of the modules to process the content in a manner that accommodates the change.

2. The method as recited in claim 1, wherein the graphics processor includes a graphics processing unit.

3. The method as recited in claim 1, wherein the modules include an encryption module.

4. The method as recited in claim 1, wherein the modules include a compression module.

5. The method as recited in claim 1, wherein the modules include a decryption module.

6. The method as recited in claim 1, wherein the modules include a decompression module.

7. The method as recited in claim 1, wherein the modules include a post-processing module.

8. The method as recited in claim 1, wherein the modules include a graphics processing module,

9. The method as recited in claim 1, wherein the modules include a compositing module.

10. The method as recited in claim 1, wherein e processing performed by the graphics processor includes at least one of decryption, decompression, post-processing, multiplexing, processing that provides for error correction, packetization, graphics rendering, compositing, re-compression, and re-encryption.

11. The method as recited in claim 1, wherein the modules are dynamically selected based on a desired quality of service.

12. The method as recited in claim 1, wherein the modules are dynamically selected based on at least one aspect of the content or the display.

13. The method as recited in claim 1, wherein the modules are dynamically selected based on at least one aspect of the available bandwidth of the wireless network link.

14. The method as recited in claim 1, wherein the processing is adapted as a function of a type of processing carried out by a second graphics processor in communication with the graphics processor via a network.

15. The method as recited in claim 14, wherein the second graphics processor receives the content from the graphics processor over the wireless network link and the processing is adapted as function of the type of the processing carried out by the second graphics processor by changing the processing as the function of the type of the processing carried out by the second graphics processor.

16. The method as recited in claim 14, wherein a first amount of processing performed by the graphics processor is a reciprocal function of a second amount of processing performed by the second graphics processor.

17. A computer program product embodied on a non-transitory computer readable medium, comprising:

computer code for dynamically selecting one or more modules of a graphics or video processor for processing content to support communication of the content over a wireless network link for subsequent display of the content utilizing a display;

wherein the processing includes preparing the content for transmission over the wireless network link;

wherein the computer program product is operable such that in response to detection by a transmitter utilized for transmitting the content over the wireless network link of a change in available bandwidth of the wireless network link, the transmitter instructs at least one of the modules to process the content in a manner that accommodates the change.

18. A system, comprising:

a processor capable of graphics processing or video processing, the processor including a plurality of modules adapted for being dynamically selected to process content to support communication over a wireless network link and subsequent display of the content utilizing a display;

wherein the processing includes preparing the content for transmission over the wireless network link;

wherein the system is operable such that in response to detection by a transmitter utilized for transmitting the content over the wireless network link of a change in available bandwidth of the wireless network link, the transmitter instructs at least one of the modules to process the content in a manner that accommodates the change.

19. The system as recited in claim 18, wherein the processor is integrated with a computer.
