Title (EN) SYSTEM TO PROVIDE ACCESS TO INFORMATION RELATED TO A BROADCAST SIGNAL
(FR) SYSTEME DONNANT ACCES A DES INFORMATIONS RELATIVES A UN SIGNAL DE RADIODIFFUSION
Abstract:
(EN) A system to provide access to information (1) related to an audio or video signal (12) being distributed to a multiplicity of people at a given time includes watermarking means (9) for inserting identification codes into said audio or video signal before or at the time of distribution, said codes consisting of information identifying the time of distribution and the identity of the distributor, means (14) for reading the identification codes and associating a block of data stored in a data store with said identification codes, and communication means (6) such as a mobile phone for one or more person who has received said audio or video signal to access said block of data using either said identification codes or the identity of the distributor and the time of distribution.
(FR) L'invention se rapporte à un système donnant accès à des informations (1) relatives à un signal audio ou vidéo (12) distribué à un grand nombre de personnes à un moment donné, comprenant : un moyen de tatouage numérique (9) permettant l'insertion de codes d'identification dans ledit signal audio ou vidéo, avant ou pendant le moment de la distribution, lesdits codes étant constitués d'informations indiquant le moment de la distribution et l'identité du distributeur ; un moyen (14) destiné à lire les codes d'identification et à associer un bloc de données stocké dans une mémoire de données auxdits codes d'identification ; et un moyen de communication (6), tel qu'un téléphone mobile, permettant à la ou les personnes ayant reçu ledit signal audio ou vidéo d'accéder audit bloc de données, à l'aide soit desdits codes d'identification, soit de l'identité du distributeur et du temps de distribution.
