Extending the multimedia class hierarchy for hypermedia applications

Abstract

Abstract The convergence of digital presentation technologies, including video, audio, images, full colour, and animation, has given rise to the development of multimedia and hypermedia presentation systems. Multimedia systems are based on the synchronization and co-ordination of data through media specific software and hardware so that data of a variety of media types enhance the overall impact of the presentation. Hypermedia applications include user-driven access mechanisms and links among such objects. New generations of hypermedia applications that exploit a larger range of multimedia types than are generally included in the multimedia class hierarchies are rapidly becoming available. In this paper we introduce two additional multimedia types, computational and directive, that depend on direct interaction with die user and increase the use of computing facilities within hypermedia presentations. The recognition of interactive media types provides fertile ground for new classes of hypermedia link type...
