Abstract: A technique for providing routing of various multimedia events throughout the course of a multimedia presentation using a computer with a storage and a display. A variety of multimedia objects are defined in the storage and grouped in logical relationships to enable multimedia presentations. A display is used to create the presentations interactively by positioning objects representative of the multimedia events and joining them with geometric figures, such as line segments. Each object can then be directly manipulated via a mouse or other pointing device to position a multimedia object to a particular position, or adjust the playback rate of a multimedia object.

Abstract: A system for connecting a video object to various multimedia objects to enable an object-oriented simulation of a multimedia presentation using a computer with a storage and a display. A plurality of multimedia objects are created on the display including at least one connection object and at least one video object in the storage. Multimedia objects are displayed on the display, including at least one video object. The multimedia object and the video object are connected, and information is routed via the connection between the multimedia object and the video object to create a multimedia presentation.

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.

Abstract: A method and system for controlling various multimedia objects throughout the course of a multimedia presentation on a computer with a storage and a display utilizes a control object defined in the storage and associated with each multimedia object. The control objects each contain an internal current time value which is used to control presentation of multimedia data by the associated multimedia object. The internal current time value is calculated as a function of an input time value and control objects can be connected together so that the internal current time value of one clock object serves as the input time value of another clock object so that multimedia objects can be synchronized. Each control object can also be directly manipulated via a mouse or other pointing device to directly control the associated multimedia object to position the object to a particular position in time, or adjust the playback rate.

Abstract: A method and system for providing synchronization of the timing of various multimedia events, including a visual event is disclosed. Clock objects are defined in the storage and associated with an internal or external source of current time. The clock objects are able to be displayed on the display, but can be hidden once their linkages are defined. One or more multimedia objects representative of audio, visual or other multimedia events, including an audio object, are defined and linked to a particular clock object or clock objects. Then, a processor synchronizes the multimedia objects, including a visual object, with the associated clock object or objects. Finally, the various multimedia events are performed in synchronization with their associated clocks. The multimedia objects, including the visual object, may include external multimedia sources managed by the computer system.
