Abstract: The invention relates to a method and a device for synchronising metadata associated by a first signature to a first version of an audiovisual document, with a second version of this audiovisual document. The method is characterised in that it synchronises the metadata with the second version of the audiovisual document from a second signature detected in the portion of the second version of the audiovisual document, said portion of the second version of the audiovisual document being obtained by detecting the first signature in the second version of the audiovisual document. In this way, the precision of the synchronisation between the two items of video content carried out by the first signature is improved by the second signature, and new, more accurate metadata is created.
