Abstract: In a sharing session between a presenter and several attendees, the presenter can share any type of document quickly and without substantial prior preparation. The presenter's device identifies an active document-sharing window within the desktop sharing environment, and detects if there is a shared document in the active window. The presenter's device creates a framework for any detected shared document that is transmitted to each of the attendee devices. The framework contains information about the pages in the shared document, such that an attendee device can request a specific page in the shared document. At least the first page of the shared document is rendered to a page image and transmitted to the attendee devices. Upon request from an attendee device, page images of any of the remaining pages may be sent to the attendee device, allowing each attendee to view a different page than the presenter.

Abstract: A presenter device transmits, to an attendee device participating in an online desktop sharing session, image data of a plurality of windows. The plurality of windows comprises a foreground window obscuring at least a portion of at least one background window. The presenter device captures image data of at least one background window including the obscured portion of the background window without altering the display of the presenter device. A request is received from the attendee device for image data of at least one background window to display the background window over the foreground window on a display of the attendee device. In response to receiving the request, the presenter device transmits the captured image data of the background window, including any obscured portion, to the attendee device.
