A REAL-TIME SLIDE PRESENTATION MULTIMEDIA DATA OBJECT AND SYSTEM AND METHOD OF RECORDING AND BROWSING A MULTIMEDIA DATA OBJECT |
摘要 |
A system for recording a real-time slide presentation to generate a low bit-rate multimedia data object including a plurality of synchronized overlayed replayable bitstreams including at least a bitstream corresponding to an image of each of a plurality of slides of the slide presentation, a bitstream corresponding to symbolic representations of presenter's interactions with points of interest within each slide, and a bitstream corresponding to a presenter's audio associated with each slide is described. The plurality of bitstreams can be linked so as to make the multimedia data object browsable on a presenter interaction event-by-event basis. Interaction events can be linked to the audio bitstream and/or to a video clip bitstream. Video clips can be recorded during the real-time presentation such that when replaying the multimedia data object, a video clip is synchronized and replayed dependent on presenter interaction events. |
