  • Patent number: 5515490
    Abstract: A method and system automatically produce a temporal layout for controlling the presentation of a multimedia document. A partial temporal layout, or schedule, is produced during a compiletime phase of the method from duration information about the media items included in the document, and from the temporal relationships between the media items, as specified by a document author. Several temporal relationships are supported, including "simultaneous with", for synchronization of two media items or events, and relationships such as "before by 10 seconds." The temporal formatter positions media data items having predictable behavior in time according to the specified temporal relationships and using the specified durations, and creates an auxiliary temporal layout with unresolved times for each media data item or event therein having unpredictable behavior.
