A multimedia authoring system uses a graphic interface display which is implemented as a part of a flow editor and is used to create and to program interactive multimedia presentations and coursework. The authoring system also includes other editors (e.g., a database editor, an expression editor, and an object editor) used to perform other editing functions required to create presentations. The system also includes control systems (e.g., an applications mover, a videodisc controller, and a help system) which also enable the user to create, program, execute and manipulate interactive multimedia presentations. Finally, the system includes an evaluator which evaluates a programmed presentation and implements the presentation. A process of creating and evaluating a presentation using selectable icons from an icon menu area of the display screen and a grid area of the display screen includes receiving an input selecting an icon from the icon menu area, storing in the memory a data structure associated with the selected icon, displaying a new icon corresponding to the data structure on the grid area, and performing an action represented by an action identifier included in the data structure.

Methods and apparatus for a multimedia authoring and presentation system

A data processing system has a central processing unit, a memory for storing a plurality of data structures corresponding to a presentantion, and a display device. The display device has a display screen including a presentation area for displaying a presentation. Each one of the data structures includes an action identifier and a plurality of attributes. The process provides for receiving a one of the plurality of data structures of the presentation, analyzing the received data structure to determine an action to be performed in response to the action identifier of the data structure, and performing the action corresponding to the action identifier in accordance with a plurality of the attributes of the received data structure.

Methods and apparatus providing for a presentation system for multimedia

A process performed in a data processing system includes receiving an input selecting one of the plurality of multimedia presentations to be relocated from the first memory to the second memory, scanning the linked data structures of the selected multimedia presentation to recognize a plurality of resources corresponding to the selected multimedia presentation, and generating a list of names and locations within the selected multimedia presentation corresponding to the identified plurality of resources. The process also includes renaming the names on the generated list, changing the names of the identified plurality of resources in the selected multimedia presentation to the new names on the generated list, and moving the selected multimedia presentation and the resources identified on the generated list to the second memory.
