Abstract
Commands associated with an update allow a presenter display to be recreated by a viewer. The commands are delineated by end of update markers. Commands are transmitted to viewers in viewer updates to allow viewers to see information that was shown on the presenter display as it existed at a particular point in time. A target end of update marker will be selected for a viewer update and all commands necessary to recreate the presenter display at that point in time will be transmitted to the viewer. Since the target end of update marker may cause several presenter updates to be included in a given viewer update, some of the commands in the update queue may not need to be transmitted to the viewer. Prunability indicators are therefore added to commands to allow commands to be selected for transmission to a viewer based on the target end of update marker.
