Synchronizing presentation states between multiple applications

摘要

A presentation state is received from the presenting application. The presentation state may represent a current state of the local presentation. A request for the presentation state is received from the viewing application. In response to receiving the request for the presentation state, the presentation state is provided to the viewing application. A request for presentation data synchronized to the presentation state is received from the viewing application. In response to receiving the request for presentation data synchronized to the presentation state, the presentation file is transformed into the presentation data synchronized to the presentation state. The presentation data synchronized to the presentation state is provided to the viewing application. The viewing application may be operative to read the presentation data and to display a remote presentation in response to reading the presentation data.
