A system for generating a data object of a recording of a real-time slide presentation is described. The data object includes a plurality of synchronized overlaid 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. The system generates the bitstream corresponding to the symbolic representation of the presenter's interactions from captured image data of the real-time presentation by identifying points of interest of located objects in front of the display area and assigning symbols to each point of interest. The symbolic representation bitstream is then synchronized with a corresponding audio bitstream and the slide image data of the presentation. |
