Title (EN) METHOD AND SYSTEM FOR SYNCHRONISING VIDEO AND DATA
(FR) PROCÉDÉ ET SYSTÈME POUR SYNCHRONISER UNE VIDÉO ET DES DONNÉES
Abstract:
(EN) The method comprises: - generating a marked video signal by extracting an image fragment (V) from a region (R) of an original frame (F), and arranging a watermark (M) thereon; and - generating a data signal, including therein the extracted image fragment extracted (V) and/or reconstruction information; - performing an additional synchronisation step, which comprises: - obtaining, from the data signal, the image fragment (V) and/or the reconstruction information, - obtaining, from the marked video signal, an incomplete frame (Fr), and - attempting to reconstruct the original frame (F) from the information obtained from the data signal and the marked video signal, and, if the reconstruction is successful, determining that the synchronisation is correct. The system is adapted to implement the method of the invention.
(FR) La présente invention concerne un procédé qui consiste à : - générer un signal vidéo marqué par extraction d’un fragment d’image (V) à partir d’une région (R) d’une trame d’origine (F), et agencer un tatouage numérique (M) sur celui-ci ; et - générer un signal de données, comprenant dans celui-ci le fragment d’image extrait (V) et/ou des informations de reconstruction ; - réaliser une étape de synchronisation supplémentaire, qui consiste à : - obtenir, à partir du signal de données, le fragment d’image (V) et/ou les informations de reconstruction, - obtenir, à partir du signal vidéo marqué, une trame incomplète (Fr), et – tenter de reconstruire la trame d’origine (F) à partir des informations obtenues à partir du signal de données et du signal vidéo marqué et, si la reconstruction est réussie, déterminer que la synchronisation est correcte. Le système est conçu pour mettre en œuvre le procédé selon l’invention.
