Abstract: The invention concerns a device for inserting additional video content (inlays, secondary programs) into a main video program. Said device works in baseband within a single encoding box under the control of a common supervisor. The supervisor is configured to pass metadata associated with the images to the coder, said metadata comprising temporal, spatial and dynamic data relating to the planning of the insertion, and analysis data for the image files, which analysis data have been produced prior to the insertion. The coder receives said metadata and is configured to deduce therefrom optimization strategies for the coding that are implemented by line coding and file coding processes that are capable of being carried out simultaneously or sequentially.
