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 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.
