ABSTRACT:
A visual 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 represented as playback icons on a playback "score" analogous to a musical score. The present invention further creates and displays a corresponding download score, on which download icons (corresponding to playback icons on the playback score) are initially deployed as rectangles and arranged according to default rules. The topographical area of the download icons, as displayed, corresponds to the data size of the media objects. The designer then ordains a bandwidth constraint ("pipe") causing the download icons to be compressed into the pipe, likely overlapping. The designer may now arrange the download icons within the pipe by adapting the shape of the download icons into square-cornered polygons that no longer overlap within the pipe. The system meanwhile keeps the topographical area of the download icons constant, regardless of the shape into which the designer adapts them. Eventually, as the playback score becomes more information-rich, the designer will no longer be able to adapt the shape of download icons within the pipe without causing delivery to fall behind demand for playback. The invention highlights this condition to the designer, who must then take corrective action.
