Abstract:
The invention concerns a method for embedding video annotation data into a coded video stream. The method comprises the step of —encapsulating said video annotation data into a unit, so-called video annotation unit, of the coded video data stream which format corresponds to at least one format used for sending the associated video data, —inserting an identifiable synchronizing code enabling the identification of said video annotation unit into the video data stream.
