Abstract
An object-oriented framework is used to create multimedia application programs which route multimedia data from a multimedia source, such as a storage, to a multimedia presentation device for presentation. A variety of multimedia objects are defined in the storage, each of which has input and output ports, and a display is used to create the presentations by means of interactive graphics. Each of the objects generates its own graphic image and the application program is created by positioning the graphic images on the display and connecting them together with other connecting objects that generate graphic images, such as line segments. When the graphic images are connected, the underlying objects connect their input and output ports together to form the multimedia application program. The connecting objects can also perform data processing in the process of passing information from one object to another.
