FIELD: physics, computer engineering.

SUBSTANCE: invention relates to synchronisation of presentation states between multiple applications. 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 synchronised to the presentation state is received from the viewing application. In response to receiving the request for presentation data synchronised to the presentation state, the presentation file is transformed into the presentation data synchronised to the presentation state. The presentation data synchronised 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.
