Abstract
A tool for scheduling the delivery of media objects within varying constraints of available bandwidth. In a preferred embodiment in which the invention is enabled by software executable on a general purpose multimedia grade computer, a system designer orchestrates the playback of a series of media objects on a playback "score" analogous to a musical score. The system designer can also see the results of his or her work by playing back the playback score in real time on a corresponding runtime view. The media objects are represented on the playback score as playback icons. Responsive to the designer's manipulation of playback icons on the playback score, the present invention further creates and displays a corresponding download score, also viewable by the system designer, in which download icons (corresponding to playback icons on the playback score) are automatically deployed and arranged to fill up a displayed "pipe" of available bandwidth. The topographical area of the download icons, as displayed, corresponds to the data size of the media objects. The download icons are displayed as rectangular or square-cornered polygonal shapes. As the playback score becomes more information-…
