CONTROL SCHEDULER APPARATUS AND METHOD FOR SYNCHRONOUSLY OUTPUTTING PRESENTATION DATA FOR MULTIMEDIA PRESENTATIONS

摘要

The present invention provides a control scheduler apparatus for synchronously outputting presentation data for multimedia presentations. The control scheduler apparatus includes a media editing unit including text, graphic, sound and moving picture editors for executing presentations. A scenario producing unit receives the various multimedia data output from the media editing unit and constructs a presentation scenario by temporally and spatially composing the multimedia data. A network synchronizing unit synchronizes respective media data to allow the user to execute presentations using the various multimedia data through the scenario producing unit. A presentation control unit outputs a control signal to allow the user to precisely execute the presentations based on a defined scenario depending on given temporal and spatial relationships. An output synchronizing unit synchronizes presentation data based on a requested presentation output time and a network transmission delay to precisely execute the presentations depending on the scenario.
