Abstract

In one embodiment, a method for providing a user interface to a client device is provided, the method comprising: sending, to the client device, a browser web page compatible with a browser operable on the client device, the browser web page including a capability to receive content updates from a server according to a server-defined protocol and a capability to send events from the client device to the server; receiving content from a content source; sending the content to the client device according to the server-defined protocol; and sending a partial update of the content to the client device according to the server-defined protocol.

Claims

1. A method for providing a user interface to a client device, the method comprising:

sending, to the client device, a browser web page compatible with a browser operable on the client device, the browser web page including a capability to receive content updates from a server according to a server-defined protocol and a capability to send events from the client device to the server;

receiving content from a content source;

sending the content to the client device according to the server-defined protocol; and

sending a partial update of the content to the client device according to the server-defined protocol.

2. The method of claim 1, further comprising:

receiving, from the client device, a request for updated content, the request generated by the capability to send events of the browser web page.

3. The method of claim 2, wherein the sending a partial update includes sending the partial update when the server receives the partial update.

4. The method of claim 1, wherein the capability to receive content updates from a server includes one or more codecs.

5. The method of claim 1, wherein the capability to send events from the client device to the server is a Javascript script.

6. The method of claim 1, further comprising:

sending a first layer to the client device, wherein the first layer includes a video stream; and

wherein the content represents a second layer, wherein the second layer includes graphics to overlay onto the video stream.

7. The method of claim 1, wherein the content includes an image and wherein the sending the content includes:

splitting the image into multiple tiles;

sending the multiple tiles to the client device for display in a table; and

wherein the sending a partial update includes sending a replacement for one of the multiple tiles to the client device.

8. The method of claim 1, wherein the content includes an image and wherein the sending the content includes sending the image to the client device for display in a table, and wherein the sending a partial update includes:

sending a region of the image that has been updated to the client device for overlay in the table.

9. The method of claim 1, further comprising:

receiving a request from the client device related to a keyboard or mouse input on the client device; and

passing the request to an application located on the server.

10. A method for operating a client device, the method comprising:

receiving, from a server, a browser web page compatible with a browser operable on the client device, the browser web page including a capability to receive content updates from the server according to a server-defined protocol and a capability to send events from the client device to the server;

rendering a remote user interface by running the browser web page in a browser;

receiving content from the server and rendering the content in the remote user interface; and

receiving a partial update of the content from the server and rendering the partial update in the remote user interface.

11. The method of claim 10, further comprising:

receiving, from a user, a selection by the user to browse a remote user interface; and

sending a request for the remote user interface to a server containing the remote user interface.

12. The method of claim 10, wherein the capability to receive content updates from a server includes one or more codecs.

13. The method of claim 10, wherein the capability to send events from the client device to the server is a Javascript script.

14. The method of claim 10, wherein the rendering the content includes rendering a first layer, wherein the first layer includes a video stream, and rendering a second layer, wherein the second layer includes graphics to overlay onto the video stream, and wherein the rendering the partial update includes rendering an updated portion of the second layer.

15. The method of claim 10, wherein the rendering the content includes rendering multiple tiles, wherein the multiple tiles represent pieces of a single image, and wherein the rendering the partial update includes rendering an updated one of the multiple tiles.

16. The method of claim 10, wherein the rendering the content includes rendering an image in a table, and wherein the rendering the partial update includes rendering a region of the image that has been updated to the client device for overlay in the table.

17. The method of claim 10, further comprising:

receiving a keyboard or mouse input from a user; and

capturing the keyboard or mouse input using the browser;

issuing one or more events related to the keyboard or mouse input from the client device to the server.

18. The method of claim 10, further comprising:

periodically polling the server for partial updates.

19. A server comprising:

a memory;

a processor;

an application; and

a remote user interface server module configured to;

send, to the client device, a browser web page compatible with a browser operable on the client device, the browser web page including a capability to receive content updates from a server according to a server-defined protocol and a capability to send events from the client device to the server;

receiving content from a content source;

sending the content to the client device according to the server-defined protocol; and

sending a partial update of the content to the client device according to the server-defined protocol.

20. A client device comprising:

a memory;

a processor;

a web browser configured to;

receive, from a server, a browser web page compatible with, the browser web page including a capability to receive content updates from the server according to a server-defined protocol and a capability to send events from the client device to the server;

render a remote user interface by running the browser web;

receive content from the server and render the content in the remote user interface; and

receive a partial update of the content from the server and render the partial update in the remote user interface.
