Audiovisual video characterization using audio watermarking scheme

Due to the incessant explosion of the multimedia documents amount, the use of metadata is becoming crucial to facilitate the retrieval and the management of these audiovisual contents. Metadata creation is highly time and resources consuming even if the process is automatically done. Thus, video browsing systems uses existing metadata files generally jointed to the corresponding video for efficient semantic multimedia content retrieval. However, missing the metadata file renders the related video useless. So, in this paper, a new strategy for video characterization is described by embedding the metadata information using a blind watermarking technique. Consequently, browsing systems can use the beforehand indexed content just by extracting the corresponding metadata.
