Abstract:
1. An authoring method for use in creating an audiovisual product, comprising the steps of: defining a plurality of components, the components implicitly representing functional sections of audiovisual content with respect to one or more raw content objects to be used in an audiovisual product, and a plurality of transitions that represent movements between the plurality of components; providing to a computer platform an executable code which when executed by the computer platform enables the computer to automatically expand the plurality of components and the plurality of transitions to automatically generate a set of explicitly realized AV assets and an expanded intermediate datastructure of nodes and links, including expanding a component of the plurality of components to automatically generate a plurality of nodes, and expanding a transition of the plurality of transitions to automatically generate a plurality of links, where each node is associated with an AV asset of the set, the links represent movement from one node to another and the intermediate datastructure represents a navigational structure of the audiovisual product; and creating the audiovisual product for a playback device in a predetermined output format, using the AV assets and the expanded intermediate datastructure of the nodes and the links, the created audiovisual product having a navigational structure corresponding to a structure represented by the intermediate datastructure.
