ABSTRACT:
An apparatus and method for controlling copying of a video signal are provided for detecting a copy preventing signal, and for stopping recording and informing the user that a video signal to be recorded is protected against copying when a video signal having a copy-preventing signal is detected. In the apparatus and method, a copying (or recording) mode is stopped, and the user is informed that a recording medium to be copied is protected against illegal copying when a copy-preventing signal is detected from a video signal reproduced from the recording medium to be copied, thereby allowing the user to quickly recognize that the recording medium to be copied includes a copy-preventing signal before completing the copying. In addition, when the apparatus and method are applied to a dual deck VCR, FM copying can be controlled depending on whether a macrovision signal exists on the basis of the beginning date on which the aggressive protection of copyright becomes effective.
