Abstract

(EN) A recording medium on which an information signal is recorded, wherein a first watermark to be transmitted when the information signal is transmitted in the form of an analog signal and a second watermark to be transmitted when the information signal is transmitted in the form of a digital signal are buried in the information signal.

(FR) L'invention concerne un support d'enregistrement sur lequel un signal d'information est enregistré, une première empreinte à transmettre lorsque le signal d'information est émis sous forme d'un signal analogique et une seconde empreinte à transmettre lorsque ledit signal d'information est émis sous forme d'un signal numérique étant enterrées dans ledit signal d'information.
