....in the academic literature, since they explore the more innovative approaches. We have also chosen, however, to include a number of commercial systems, since these have survived a number of years of use by real authors. While a large selection of commercial authoring systems is available ( 18] [21], 34] 36] 2 ) we have chosen Authorware, IconAuthor and Director as being representative of the more widely used, and thus better, authoring applications. A number of different underlying paradigms are supported by multimedia authoring systems. The majority of systems fall under the ....
....media items as they are being played. When the system has sufficient time it looks ahead in the presentation and fetches data that will be needed. The stages of this pre scheduling are also shown by highlighting the media items in the channel view. Further details on the scheduling are given in [21]. Creating hyperlinks Presentations can be made interactive by providing choice points. This can be done via the use of scripts, but this leads to a navigation structure that is difficult to maintain. In order to give the author better control over the navigation structure, we use the Amsterdam ....

....be difficult to describe even more detailed relationships, such as: display the picture when a phrase pretty picture is spoken in the audio object. It is also difficult to model hyper navigation behavior in this type of system. Examples of flowchart based authoring paradigms are reviewed in [24]. An example of a recent Petri net based authoring system is [5] An example of a hybrid system is Eventor [13] which uses CCS (Calculus of Communicating Systems) as an underlying formal specification mechanism, while providing a flowchart like user interface. Eventor also incorporates timeline ....

....for low cost multimedia systems is intersecting with the next generation products and services of the computer, telecommunications, and consumer entertainment industries. The direct impact on education includes richer instructional materials (Apple, 1991) more powerful presentation tools (Koegel Heines, 1993), and access to geographically distributed educational services and databases. The indirect effects will also be considerable, including a student population which is not only media conversant but is media oriented due to daily use of interactive television, videophones, sophisticated video games, ....
