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