COPY GUARD STATE INDICATION METHOD AND VIDEO SIGNAL PROCESSING DEVICE

摘要

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.
