CA 2233891

A copy guard state detection unit detects whether copy guard is applied to the input video signal. If the copy guard state detection unit detects that copy guard is applied to the input video signal, a LED lights or blinks. Further if copy guard is applied to the input video signal and the recording device is in recording state or record waiting state, then the display information generation unit generates a display information for indicating that copy guard is applied to the input video signal, and the display information is displayed on a LCD.

L'invention est une unité de détection de protections contre la duplication qui détecte si une telle protection a été appliquée à un signal vidéo. Quand cette unité de détection détecte la présence d'une telle protection, une diode luminescente s'allume ou se met à clignoter. De plus, quand le signal vidéo est protégé et que l'appareil d'enregistrement est en mode d'enregistrement ou de préenregistrement, l'unité de détection produit une information indiquant que le signal vidéo est protégé et affiche cette information sur un afficheur à cristaux liquides.
