Abstract
Abstract The present invention concerns a multimedia presentation computer program that includes method and apparatus for sharing presentation functions between portions of the program by means of an interface that is implemented as one or more dynamically linked custom programs that perform one or more functions as the multimedia presentation computer program executes. A number of interface methods in the multimedia presentation computer program are declared and are implemented in the custom program The interface methods of the custom program are made accessible to the multimedia presentation computer program by means of an identifier. A host program within the multimedia presentation computer program communicates with the custom program by means of custom program parameters that at least in part define operation of the custom program. The custom program executes and thereby implements its one or more functions for use by the multimedia presentation computer program.

Claim 9
Dependent Claim
31 words
The method of claim 1 wherein the multimedia program implements a persistance method to allow a state of the dynamically linked object to be saved and reloaded from a storage medium.
Claim 10
Dependent Claim
25 words
The method of claim 1 where the presentation function performed by the dynamically linked object can be undone by communicating with the multimedia presentation software.
Claim 11
Dependent Claim
134 words
A stored program for use with a multimedia presentation computer program executing in a computing operating environment that maintains a registry, said multimedia program providing a plurality of presentation functions, said program comprising: a) one or more dynamically-linked custom programs, each said custom program receiving a multimedia input from the multimedia presentation computer program, implementing one or more functions on the respective multimedia input, and providing the multimedia presentation computer program with the implemented one or more functions; b) host software that forms part of the multimedia presentation computer program and provides an interface for communicating with one or more dynamically-linked computer programs; and c) helper functions for registering the one or more dynamically-linked custom programs in the operating system registry to allow the host program interface to communicate with the dynamically-linked custom programs.
