Abstract
Updates may be transmitted over a remote viewing session using a transmission protocol configured to allow sessions to be established, terminated, and used by participants. The transmission protocol provides a message structure that may be used to exchange administrative information associated with the session, as well as host display information to be transmitted from the host to the viewers over the session. A bounding rectangle construct may be used to convey positional information associated with the update or content of an update message. The messages may be passed directly between the host and viewers or via an intermediate service. The messages also may be used to allow viewers to highlight information on the display for a limited period of time so that the highlighting appears to the host and optionally to the other viewers on the session.
