Abstract:
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.

Claim (Index 1):
Method for synchronising video and data, which comprises:\n i) providing at least one marked video signal that includes one video signal which comprises at least one marked frame (Fm) that includes one watermark (M) on one region (R) of at least one original frame (F), wherein said watermark (M) includes encoded synchronisation information about said at least one original frame (F) with data associated thereto; ii) sending said marked video signal to a receiver (R) with access to a data signal that contains said associated data; and iii) performing a synchronisation step which comprises said receiver (R) extracting the synchronisation information included in the watermark (M) of said marked frame (Fm) of the marked video signal, decoding it and using it to synchronise said original frame (F) with said data associated thereto; the method being characterised in that:\n said step i) comprises: \n ia) generating said marked video signal by extracting an image fragment (V) from a region (R) of said original frame (F), and arranging said watermark (M) on said region (R) of said frame (F), replacing said extracted image fragment (V), to obtain said marked frame (Fm); and \n ib) generating said data signal, including therein said extracted image fragment (V) and/or reconstruction information that allows for the reconstruction thereof; \n said step iii) comprises: \n iiia) performing said synchronisation step; and \n iiib) said receiver (R) performing an additional synchronisation step which comprises:\n iiib1) obtaining, from the data signal, the image fragment (V) and/or the reconstruction information included therein, \n iiib2) obtaining, from the marked video signal received, an incomplete frame (Fr) that includes said original frame (F) without the watermark (M) and without the extracted image fragment (V), and \n iiib3) attempting to reconstruct the original frame (F) from the information obtained in iiib1) and iiib2), and, if the reconstruction is successful, determining that the frame of the video signal and the associated data of the data signal are duly synchronised.
