Abstract

Examples of systems and methods are provided for handling remote drawing commands. A system may comprise a buffer module configured to receive, at the system from a remote server system over a remote access connection between the system and the remote server system during a remote connection session, remote drawing commands, according to a drawing command rate, of a remote application running on the remote server system. The buffer module may be configured to store the remote drawing commands. The system may comprise a timer module configured to facilitate sending at least some of the remote drawing commands in the buffer module to a graphics module according to a refresh rate that is less than the drawing command rate. The timer module may be application agnostic.

Claims

1. A method for handling drawing commands on a client device, the method comprising:

receiving drawing commands at the client device over a network connection from a remote server system according to a drawing command rate;

storing the drawing commands in a buffer module in the client device;

monitoring the buffer module for a change to the buffer module, according to a monitor rate;

detecting the change to the buffer module; and

sending at least one of the drawing commands in the buffer module to a graphics system in the client device according to a refresh rate that is less than the drawing command rate, the at least one of the drawing commands corresponding to the change to the buffer module.

2. The method of claim 1, wherein receiving drawing commands at the client device comprises:

establishing a remote access connection with a remote server system; and

receiving remote drawing commands from the remote server system.

3. The method of claim 1, wherein the graphics system is configured to display the at least one of the drawing commands on a local display according to the refresh rate.

4. The method of claim 3, wherein the refresh rate is less than or equal to the monitor rate.

5. The method of claim 3, wherein the refresh rate is less than or equal to approximately 60 hertz.

6. The method of claim 1, further comprising detecting a relationship between two related drawing commands, wherein the at least one of the drawing commands in the buffer module sent to the graphics system comprises both of the two related drawing commands.

7. The method of claim 1, wherein the drawing commands comprise at least one of a raster operation, a multimedia frame, and a texture.

8. A client device for handling remote drawing commands, the device comprising:

a processor;

a buffer module communicatively coupled to the processor;

a graphics system communicatively coupled to the buffer module; and

a memory communicatively coupled to the processor;

instructions encoded in the memory, wherein the instructions, when executed by the processor, are operable to;

receive drawing commands over a network connection from a remote server system according to a drawing command rate;

store the drawing commands in the buffer module;

monitor the buffer module for a change to the buffer module, according to a monitor rate;

detect the change to the buffer module; and

send at least one of the drawing commands in the buffer module to the graphics system according to a refresh rate that is less than the drawing command rate, the at least one of the drawing commands corresponding to the change to the buffer module.

9. The device of claim 8, wherein receiving drawing commands comprises:

establishing a remote access connection with a remote server system; and

receiving remote drawing commands from the remote server system.

10. The device of claim 8, further comprising a local display, wherein the graphics system is configured to display the at least one of the drawing commands in the buffer module sent to the graphics system on the local display, according to the refresh rate.

11. The device of claim 10, wherein the refresh rate is less than or equal to the monitor rate.

12. The device of claim 10, wherein the monitor rate is less than or equal to about 60 hertz.

13. The device of claim 8,

wherein the instructions are further operable to detect a relationship between two related drawing commands,

wherein the at least one of the drawing commands in the buffer module sent to the graphics system comprises both of the two related drawing commands.

14. The device of claim 8, wherein the drawing commands comprise at least one of a raster operation, a multimedia frame, and a texture.

15. A non-transitory machine-readable medium encoded with instructions executable by a processing system on a client device, the instructions operable to:

receive drawing commands at the client device over a network connection from a remote server system according to a drawing command rate;

store the drawing commands in a buffer module in the client device;

monitor the buffer module for a change to the buffer module, according to a monitor rate;

detect the change to the buffer module; and

send at least one of the drawing commands in the buffer module to a graphics system in the client device according to a refresh rate that is less than the drawing command rate, the at least one of the drawing commands corresponding to the change to the buffer module.

16. The non-transitory machine-readable medium of claim 15, wherein receiving drawing commands comprises:

establishing a remote access connection with a remote server system; and

receiving remote drawing commands from the remote server system.

17. The non-transitory machine-readable medium of claim 15, wherein the graphics system is configured to display the at least one of the drawing commands in the buffer module sent to the graphics system on a local display, according to the refresh rate.

18. The non-transitory machine-readable medium of claim 17, wherein the refresh rate is less than or equal to the monitor rate.

19. The non-transitory machine-readable medium of claim 17, wherein the refresh rate is less than or equal to about 60 hertz.

20. The non-transitory machine-readable medium of claim 15, wherein the instructions are further operable to detect a relationship between two related drawing commands, wherein the at least one of the drawing commands in the buffer module sent to the graphics system comprises both of the two related drawing commands.
