Abstract
(EN)
Disclosed are a video watermark adding method and apparatus, and an electronic device and a storage medium. The method comprises: converting image data of a target video frame from an RGB format into a YUV format; in the YUV format, superimposing a pre-set number of offset values on pixel values of pixel points, corresponding to the shape of a watermark to be added, on the target video frame; and encoding the target video frame after the offset values are superimposed thereon.

L'invention concerne un procédé et un appareil d'ajout de filigrane de vidéo et un dispositif électronique et un support de stockage. Le procédé consiste à : convertir des données d'image d'une trame de vidéo cible d'un format RVB en un format YUV ; dans le format YUV, superposer un nombre prédéfini de valeurs de décalage sur des valeurs de pixel de points pixels, correspondant à la forme d'un filigrane à ajouter, sur la trame de vidéo cible ; et encoder la trame de vidéo cible après que les valeurs de décalage ont été superposées sur celle-ci.
