Abstract

A system that allows graphics to be displayed on a local device via a communication channel connected to a remote computing device.

Claims

1. A system for remote graphics using a distributed graphics stack, comprising:

a first computing device, having a first processor and running a first operating system, comprising;

a user application that is executed by the first processor;

a graphics toolkit coupled with said user application for performing graphics operations required by said user application;

a first graphics renderer coupled with said graphics toolkit for rendering a graphical user interface for the user application as requested by said graphics toolkit;

a first extension stub to said first graphical renderer coupled with said first graphics renderer for assembling rendering procedure calls into a data stream; and

a transmitter coupled with said first extension stub for transmitting the data stream generated by said first extension stub to a second computing device;

a second computing device, having a second processor and running a second operating system, comprising;

a display for displaying composed graphics;

a pixel buffer for rendering graphics;

a receiver for receiving the data stream from said first computing device;

a second extension stub coupled with said receiver for disassembling the rendering procedure calls from the received data stream;

a second graphics renderer coupled with said second extension stub for rendering the procedure calls disassembled by the second extension stub on said pixel buffer; and

a surface composer coupled with said second graphics renderer for composing graphics from said pixel buffer on said display.

2. The system of claim 1 wherein the first processor has a different architecture than the second processor.

3. The system of claim 1 wherein the first and second processor have the same architecture.

4. The system of claim 1 wherein the first processor has an architecture from the group consisting of an Intel architecture and an ARM architecture.

5. The system of claim 1 wherein the second processor has an architecture from the group consisting of an Intel architecture and an ARM architecture.

6. The system of claim 1 wherein the first operating system is of a different type than the second operating system.

7. The system of claim 1 wherein the first and second operating systems are of the same type.

8. The system of claim 1 wherein the first operating system is a multiple windows system, wherein a user application maps to its own window.

9. The system of claim 1 wherein the first operating system is a single window system, which provides a view of one application at a time.

10. The system of claim 1 wherein the second operating system is a multiple windows system, wherein a user application maps to its own window.

11. The system of claim 1 wherein the second operating system is a single window system, which provides a view of one application at a time.

12. The system of claim 1 wherein said first computing device graphics renderer comprises a SKIA renderer.

13. The system of claim 1 wherein said second computing device graphics renderer comprises a SKIA renderer.

14. The system of claim 1 wherein the first computing device is a cloud server.

15. The system of claim 1 wherein the second computing device is a desktop client.

16. A method for remote graphics using a distributed graphics stack, comprising:

assembling, by a first computing device, a plurality of rendering procedure calls into a data stream;

transmitting the data stream from the first computing device to a second computing device;

disassembling, by the second computing device, the data stream into a plurality of rendering procedure calls;

rendering the rendering procedure calls by the second computing device, to generate rendered graphics; and

composing the rendered graphics on a display of the second computing device.

17. The method of claim 16 wherein said assembling comprises compressing the plurality of rendering procedure calls, and wherein said disassembling comprises decompressing the plurality of rendering procedure calls.

18. The method of claim 17 wherein said compressing comprises tracking, by the first computing device, a local storage of objects on the second computing device, the objects having been transmitted by the first computing device to the second computing device in the data stream.

19. The method of claim 17 wherein the plurality of rendering procedure calls comprise multiple frames, each frame for composing on the display of the second computing device, and wherein said compressing applies inter-frame compression based on differences between frames.
