Abstract

Η συγκεκριμένη ευρεσιτεχνία αναφέρεται στη μέθοδο ενσωμάτωσης δεδομένων (2) σε ήχο ώστε, κατόπιν αναπαραγωγής του, να είναι δυνατή η αποκωδικοποίησή τους από ανεξάρτητη συσκευή που διαθέτει αντίστοιχο δέκτη - αισθητήρα ήχου πχ. μικρόφωνο κινητού τηλεφώνου. Η ενσωμάτωση των δεδομένων γίνεται έτσι ώστε όταν αυτά (2) αναπαραχθούν μαζί με τον κυρίως ήχο (3) να μην ενοχλούν τον ακροατή του κυρίως ήχου (3) αλλά ταυτόχρονα να μπορούν να αποκωδικοποιηθούν από τη συσκευή - δέκτη. Ο τρόπος με τον οποίο αυτό γίνεται είναι η ενσωμάτωση των δεδομένων σε συχνότητες όπου δεν περιέχεται χρήσιμη ηχητική πληροφορία αλλά όπου παράλληλα αυτά (2) μπορούν να ανιχνευτούν με τη χρήση μαθηματικών μεθόδων επεξεργασίας ψηφιακού σήματος.
