Abstract

Techniques for remotely viewing a presentation are disclosed. In accordance with these techniques, a host device executing a presentation application makes a presentation available over a network. In one embodiment, a remote device receives presentation data corresponding to a currently displayed slide of the presentation. The remote device may then display a representation of the currently displayed slide at the remote location.

Claims

1-3. -3. (canceled)

4. An electronic device comprising:

a network interface capable of communicating over a network;

a memory;

a web server;

one or more storage structures encoding a presentation application comprising one or more web server routines of the web server, wherein the presentation application, when executed by the electronic device, is capable of distributing one or more images over the network, wherein the web server is configured to;

receive a request to view a presentation comprising the one or more images over the network at a remote electronic device running a viewing application;

in response to the request, establish a communication channel between the presentation application and the viewing application; and

push the one or more images to the viewing application over the communication channel such that the display of the one or more images by the viewing application on the remote electronic device is synchronized with the play of the presentation by the presentation application; and

a processor capable of running the encoded presentation application when loaded in the memory.

5. The electronic device of claim 4, wherein the request comprises authentication information, wherein the web server authenticates the request based upon the authentication information prior to establishing the communication channel.

6. The electronic device of claim 4, wherein the request comprises one or more indicators identifying one or more of the viewing application, the remote electronic device, or display characteristics of a display associated with the remote electronic device.

7. The electronic device of claim 6, wherein one or more of a size, a resolution, or a format of the one or more images pushed to the viewing application is determined based on the one or more indicators.

8. The electronic device of claim 4, wherein each of the one or more images represent a slide or slide build displayed as part of the presentation.

9. The electronic device of claim 4, wherein one or more of a size, a resolution, or a format of the one or more images pushed to the viewing application is determined based on an available bandwidth associated with the communication channel.

10. The electronic device of claim 4, wherein the presentation application comprises one or more image export routines used to generate the one or more images.

11. A method for distributing a slide presentation, comprising:

receiving, on a computer running a web server, an input configuring a presentation to be distributed over a network as one or more images by a presentation application running on the computer;

playing the presentation on the computer;

receiving, at the web server, a request to view the presentation over the network at a remote electronic device running a viewing application;

in response to the request, establishing a communication channel over the network between the presentation application and the viewing application; and

pushing the one or more images to the viewing application over the communication channel such that the display of the one or more images by the viewing application on the remote electronic device is synchronized with the play of the presentation by the computer.

12. The method of claim 11, comprising:

prior to establishing the communication channel, authenticating the request based upon authentication information provided in the request.

13. The method of claim 11, comprising:

receiving one or more indications of remote display capability from the viewing application; and

generating or selecting the one or more images to be pushed to the viewing application based on the one or more indications of remote display capability.

14. The method of claim 13, wherein the one or more images are generated or selected to have a size, a resolution, or a format compatible with the remote display capability of the remote electronic device.

15. The method of claim 11, wherein the wherein each of the one or more images represent a slide or slide build displayed as part of the presentation.

16. The method of claim 11, comprising:

determining an available bandwidth between the presentation application and the viewing application; and

generating or selecting the one or more images to be pushed to the viewing application based on the available bandwidth.

17. The method of claim 11, wherein the one or more images are generated by exporting static images of portions of the presentation corresponding to slides or slide builds.

18. A non-transitory computer-readable media, the non-transitory computer-readable media encoding routines which, when executed on a first machine, cause acts to be performed comprising:

playing a presentation on the first machine;

receiving a request at a web server running on the first machine, wherein the request is to remotely view the presentation and is generated by a viewing application running on a second machine in communication with the first machine over a network;

establishing a communication channel between the first machine and the second machine in response to the request;

pushing one or more images to the viewing application over the communication channel such that the display of the one or more images by the viewing application on the second machine is synchronized with the play of the presentation on the first machine.

19. The non-transitory computer-readable media of claim 18, wherein the request comprises one or more indications identifying one or more of the viewing application, the second machine, or display characteristics of a display associated with the second machine.

20. The non-transitory computer readable media of claim 19, wherein the encoded routines, when executed on the first machine, cause further acts to be performed comprising:

generating or selecting the one or more images to be pushed to the viewing application based on the one or more indications.

21. The non-transitory computer-readable media of claim 18, wherein the encoded routines, when executed on the first machine, cause further acts to be performed comprising:

authenticating the request, based on authentication information included in the request, prior to establishing the communication channel.

22. The non-transitory computer-readable media of claim 18, wherein each of the one or more images represent a slide or slide build displayed as part of the presentation.

23. The non-transitory computer readable media of claim 18, wherein the encoded routines, when executed on the first machine, cause further acts to be performed comprising:

generating or selecting the one or more images to be pushed to the viewing application based on an available bandwidth associated with the communication channel.
