Abstract

Examples of methods, systems, apparatus, and machine-readable storage media are provided to facilitate access and control of a remote desktop of a remote machine by a web browser at a client device through a transcoding server without installing proprietary plug-ins or protocols on the client device. A transcoding server may translate user input requests from a web browser into input calls compatible with a remote desktop display protocol. The transcoding server may receive remote desktop drawing commands from the remote machine and translate the remote desktop drawing commands into web browser drawing updates compatible with the web browser. A transcoding server may communicate with a web browser via HTTP and communicate with a remote machine via a remote desktop display protocol. A web browser may be an HTML5 browser. A transcoding server may send drawing coordinates to the web browser via an HTTP header and may use long polling.

Claims (71)

1. A method of facilitating a remote desktop session between a web browser of a client device and a remote machine through a transcoding server, utilizing hypertext transfer protocol (HTTP) headers of HTTP for remote desktop session drawing, the method comprising:

receiving, at the transcoding server, drawing requests from the web browser at the client device;

receiving, at the transcoding server, a remote desktop drawing command from the remote machine using a remote desktop display protocol, wherein the remote desktop drawing command is based on an image of a remote desktop of the remote machine;

translating, at the transcoding server, the remote desktop drawing command into a display image and drawing coordinates for the display image, wherein translating comprises:

translating the remote desktop drawing command into a Java graphics drawing command;

updating a portion of a Java graphics bitmap of the remote desktop in response to the Java graphics drawing command;

generating coordinates for the updated portion of the Java graphics bitmap from the Java graphics drawing command;

generating the display image compatible with the web browser based on the updated portion of the Java graphics bitmap; and

obtaining the drawing coordinates for the display image based on the coordinates for the updated portion of the Java graphics bitmap;

placing, at the transcoding server, the drawing coordinates into a cookie; and

providing the display image and the drawing coordinates together to the web browser in a single HTTP response, wherein the single HTTP response comprises the cookie.

2. The method of claim 1 , wherein the display image and the drawing coordinates are compatible with HTML,

wherein the updated portion of the Java graphics bitmap represents a portion of an entire image of the remote desktop of the remote machine,

wherein the display image and the drawing coordinates represent the portion of the entire image of the remote desktop of the remote machine, and

wherein the transcoding server comprises a Java compatible web application container.

3. The method of claim 1 , wherein the display image and the drawing coordinates are compatible with HTML5.

4. The method of claim 1 , wherein the transcoding server is an intermediary between the remote machine and the client device, and wherein the transcoding server is physically separate from the remote machine.

5. The method of claim 1 , wherein the remote desktop drawing command comprises coordinates of a region of the remote desktop that has changed relative to a previous remote desktop drawing command.

6. The method of claim 5 , wherein the coordinates specify a redrawing region.

7. The method of claim 1 , wherein the drawing coordinates are compatible with JavaScript client code of the web browser, and wherein the display image is compatible with HTML of the web browser.

8. The method of claim 1 , wherein the display image comprises a scaled image of the remote desktop.

9. The method of claim 1 , wherein the display image comprises an offset image of the remote desktop.

10. A non-transitory machine-readable storage medium encoded with instructions executable by a processing system to perform a method of facilitating a remote desktop session between a web browser of a client device and a remote machine through a transcoding server, utilizing hypertext transfer protocol (HTTP) headers of HTTP for remote desktop session drawing, the instructions comprising code for:

receiving, at the transcoding server, drawing requests from the web browser at the client device;

receiving, at the transcoding server, a remote desktop drawing command from the remote machine using a remote desktop display protocol, wherein the remote desktop drawing command is based on an image of a remote desktop of the remote machine;

translating, at the transcoding server, the remote desktop drawing command into a display image and drawing coordinates for the display image, wherein translating comprises:

translating the remote desktop drawing command into a Java graphics drawing command;

updating a portion of a Java graphics bitmap of the remote desktop in response to the Java graphics drawing command;

generating coordinates for the updated portion of the Java graphics bitmap from the Java graphics drawing command;

generating the display image compatible with the web browser based on the updated portion of the Java graphics bitmap; and

obtaining the drawing coordinates for the display image based on the coordinates for the updated portion of the Java graphics bitmap;

placing, at the transcoding server, the drawing coordinates into a cookie; and

providing the display image and the drawing coordinates together to the web browser in a single HTTP response, wherein the single HTTP response comprises the cookie.

11. The non-transitory machine-readable storage medium of claim 10 wherein the display image and the drawing coordinates are compatible with HTML,

wherein the updated portion of the Java graphics bitmap represents a portion of an entire image of the remote desktop of the remote machine,

wherein the display image and the drawing coordinates represent the portion of the entire image of the remote desktop of the remote machine, and

wherein the transcoding server comprises a Java compatible web application container.

12. The non-transitory machine-readable storage medium of claim 10 , wherein the display image and the drawing coordinates are compatible with HTML5.

13. The non-transitory machine-readable storage medium of claim 10 , wherein the transcoding server is an intermediary between the remote machine and

the client device, and wherein the transcoding server is physically separate from the remote machine.

14. The non-transitory machine-readable storage medium of claim 10 , wherein the remote desktop drawing command comprises coordinates of a region of the remote desktop that has changed relative to a previous remote desktop drawing command.

15. The non-transitory machine-readable storage medium of claim 14 , wherein the coordinates specify a redrawing region.

16. The non-transitory machine-readable storage medium of claim 10 , wherein the drawing coordinates are compatible with JavaScript client code of the web browser, and wherein the display image is compatible with HTML of the web browser.

17. The non-transitory machine-readable storage medium of claim 10 , wherein the display image comprises a scaled image of the remote desktop.

18. The non-transitory machine-readable storage medium of claim 10 , wherein the display image comprises an offset image of the remote desktop.

19. A computing machine comprising the non-transitory machine-readable storage medium of claim 10 , wherein the computing machine is the transcoding server.

20. A system for facilitating a remote desktop session between a web browser of a client device and a remote machine through a transcoding server, utilizing hypertext transfer protocol (HTTP) headers of HTTP for remote desktop session drawing, the system comprising:

a processor; and

a memory having stored thereon computer-executable instructions that, when executed by the processor, are configured to cause the processor to:

receive drawing requests from the web browser at the client device;

receive a remote desktop drawing command from the remote machine using a remote desktop display protocol, wherein the remote desktop drawing command is based on an image of a remote desktop of the remote machine;

translate the remote desktop drawing command into a display image and drawing coordinates for the display image, wherein translating comprises:

translating the remote desktop drawing command into a Java graphics drawing command;

updating a portion of a Java graphics bitmap of the remote desktop in response to the Java graphics drawing command;

generating coordinates for the updated portion of the Java graphics bitmap from the Java graphics drawing command;
