    The Analog Protection System (APS), also known as Copyguard or Macrovision, is a VHS and DVD copy protection system originally developed by Macrovision. Video tapes copied from DVDs encoded with APS become garbled and unwatchable. The process works by adding pulses to analog video signals to negatively impact the AGC circuit of a recording device.

      What information is conveyed by an analog signal?
      Any information may be conveyed by an analog signal; often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position, or pressure.

      What happens when an analog signal is converted to digital?
      Converting an analog signal to digital form introduces a low-level quantization noise into the signal, but once in digital form the signal can be processed or transmitted without introducing significant additional noise or distortion. In analog systems, it is difficult to detect when such degradation occurs.

      https://en.wikipedia.org/wiki/CGMS-A

      Copy Generation Management System – Analog is a copy protection mechanism for analog television signals. It consists of a waveform inserted into the non-picture Vertical Blanking Interval of an analogue video signal. If a compatible recording device detects this waveform, it may block or restrict recording of the video content. It is not the same as the broadcast flag, which is …
