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.
