Abstract

A találmány tárgya eljárás és berendezés kiegészítő adat (W)beágyazására egy információjelbe, amelynek során kiegészítőadatmintákat (w) ágyaznak be az információjel meghatározottpozícióiba. A találmány szerint az információjel legalább kétjelcsatornát (z1, z2) tartalmaz, az eljárás során azonos kiegészítőadatmintákat (w) ágyaznak be a csatornák megfelelő pozícióiba, abeágyazó eszköz (3, 4) pedig alkalmas arra, hogy azonos kiegészítőadatmintákat (w) ágyazzanak be a csatornák megfelelő pozícióiba. Akiegészítő adatkiemelési eljárásban összehasonlítják egy adott számújel mintákkal elkülönített, előre meghatározott első csatornajel-minták egy első sorozatát a második csatornajelminták egy megfelelőmásodik sorozatával, és az első és a második sorozatot egymintapozícióval áthelyezik, és az áthelyezett első és második sorozatösszehasonlítását addig ismétlik, amíg a sorozatok nem egyeznek meg,míg a berendezés erre alkalmas eszközökkel van ellátva.
