Abstract

In particular embodiments, a computing device may receive device data from a client device. The computing device may encode the data for transmission to a remote desktop client. The re-encoding may be performed according to a pre-defined import/export protocol.

Claims

1. A method comprising:

attaching a transcoding service to a hypertext markup language (HTML) client device; and

by the transcoding service,

interfacing a web browser of the client device with a remote desktop extension protocol;

allowing the client device to connect to a remote desktop protocol (RDP) server;

importing and exporting at least one of a graphical device interface, one or more virtual channels, and one or more input/output devices to the client device;

provisioning and serializing one or more operating system function calls to allow for end-to-end communication between the client device and the RDP server when the client device and the RDP server utilize incompatible communication protocols;

providing an interface to and from the client device by a hypertext markup language (HTML) compatible stream service of the transcoding service;

reconstructing or unpacking, by the HTML compatible stream service, one or more remote client tasks to and from a remote desktop protocol;

receiving device data from the client device; and

encoding the device data for transmission to a transcoding remote desktop client with a particular port, the encoding being performed according to a pre-defined import/export protocol.

2. The method of claim 1, wherein the device data comprises input/output data from the client device.

3. The method of claim 1, wherein the client device comprises one or more of:

a mouse;

a touch device;

a keyboard;

a display;

a speaker;

or

a microphone.

4. The method of claim 1, wherein the import/export protocol is HTML5-compatible.

5. The method of claim 1, wherein the device data comprises a rendering associated with the client device.

6. The method of claim 1, wherein the client device is a remote desktop protocol client.

7. The method of claim 6, wherein the remote desktop protocol client is launched by a generic client engine.

8. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

by a transcoding service attached to a hypertext markup language (HTML) client device, interface a web browser of the client device with a remote desktop extension protocol;

allow the client device to connect to a remote desktop protocol (RDP) server;

import and export at least one of a graphical device interface, one or more virtual channels, and one or more input/output devices to the client device;

provision and serialize one or more operating system function calls to allow for end-to-end communication between the client device and the RDP server when the client device and the RDP server utilize incompatible communication protocols;

provide an interface to and from the client device by a hypertext markup language (HTML) compatible stream service of the transcoding service;

reconstruct or unpack, by the HTML compatible stream service, one or more remote client tasks to and from a remote desktop protocol;

receive device data from the client device; and

encode the device data for transmission to a transcoding remote desktop client with a particular port, the encoding being performed according to a pre-defined import/export protocol.

9. The media of claim 8, wherein the device data comprises input/output data from the client device.

10. The media of claim 8, wherein the client device comprises one or more of:

a mouse;

a touch device;

a keyboard;

a display;

a speaker;

or

a microphone.

11. The media of claim 8, wherein the import/export protocol is HTML5-compatible.

12. The media of claim 8, wherein the data comprises a rendering associated with the client device.

13. The media of claim 8, wherein the client device is a remote desktop protocol client.

14. The media of claim 13, wherein the remote desktop protocol client is launched by a generic client engine.

15. A system comprising:

a hypertext markup language (HTML) client device comprising one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to;

by a transcoding service attached to the client device,

interface a web browser of the client device with a remote desktop extension protocol;

allow the client device to connect to a remote desktop protocol (RDP) server;

import and exporting at least one of a graphical device interface, one or more virtual channels, and one or more input/output devices to the client device;

provision and serialize one or more operating system function calls to allow for end-to-end communication between the client device and the RDP server when the client device and the RDP server utilize incompatible communication protocols;

provide an interface to and from the client device by a hypertext markup language (HTML) compatible stream service of the transcoding service;

reconstruct or unpack, by the HTML compatible stream service, one or more remote client tasks to and from a remote desktop protocol;

receive device data from the client device; and

encode the device data for transmission to a transcoding remote desktop client with a particular port, the encoding being performed according to a pre-defined import/export protocol.

16. The system of claim 15, wherein the device data comprises input/output data from the client device.

17. The system of claim 15, wherein the client device comprises one or more of:

a mouse;

a touch device;

a keyboard;

a display;

a speaker;

or

a microphone.

18. The system of claim 15, wherein the import/export protocol is HTML5-compatible.

19. The system of claim 15, wherein the data comprises a rendering associated with the client device.

20. The system of claim 15, wherein the client device is a remote desktop protocol client.
