CSS (Content Scramble System) is a digital rights management (DRM) and encryption system used on DVDs to prevent unauthorized copying and playback of the content. It is a form of copy protection that uses a proprietary 40-bit stream cipher algorithm to scramble the data on the disc, making it difficult to copy or extract. Analog protection refers to the use of Macrovision copy protection, which adds deliberate distortions to the video signal to prevent copying, but this method is not used on DVDs. AACS (Advanced Access Content System) and region codes are also forms of DVD copy protection, but they do not prevent duplication by end-users using standard copy utilities like CSS does.
