Abstract: Process for the production of a multimedia edition on the basis of oral presentations from both information contained in a previously recorded audio and/or video flow, and data and reference documents associated with the audio/video information. It includes both indexing of the audio/video flow, in particular from the structure of the information contained, and an indexing of the supplementary data and reference documents. Heterogeneous data including information about the formal structure of an audio/video sequence contained in the audio and or video flow, and data relating to reference documents associated with the audio/video sequence are stored chronologically in a common database. These heterogeneous data are then processed in a spreadsheet, along a time axis which represents the passage of time in the time flow, and reworked in order to produce a complex indexing of audio/video information and supplementary data. Use for the production of multimedia editions based on oral presentations.
