Abstract

A találmány eljárás és berendezés egy infőrmációs jelben, példáűlvideőképben lévő több-bites vízjel érzékelésére, valamint az ilyenvízjel beágyazására. A több-bites érték mindegyik bitjét egy, azinfőrmációs jelbe beágyazőtt vízjelalminta adja. Az egyesvízjelalminta jelenlétének érzékelésére az ismert módszer (mindenegyes bit érzékelése) helyett a találmány szerinti eljárással azinfőrmációs jelben meglévő teljes vízjelet a több-bites értékétőlfüggetlenül érzékelik, és megvizsgálják, hőgy az alminta milyenmértékben egyezik meg az ellenőrzendő több-bites értékkel. ŕ
