Copy Protection for DVD Duplication:
How it works
It is important to choose a form of copy protection that will address the most wide range of would-be attackers and threats while offering the least potential for impacting the compatibility and playability of the original media content on the DVD.
The digital content industry utilizes several copy protection and anti-piracy methods to guard digital content. To protect content distributed on DVDs there are three main techniques:
-
CSS encryption/decryption, which is built into every DVD player. This is the most commonly used method for manufactured DVDs. The content is encrypted and software on the player decodes the fixed rules on the fly while being played back. Unfortunately, this technology was cracked more than ten years ago.
-
"Bad Sector" schemes, which deliberately place bad sectors of information into the DVD itself that cause copying software to correct the errors. Standard DVD players usually ignore these sectors and play through them. Special players look for these bad sectors to play the DVD and will inhibit playback if it sees a copied disc with the corrected errors.
-
Content Alteration is the most recent type of copy protection that attempts to disable copying and ripping programs without impacting the original content of the DVD. This type of copy protection maintains the highest level of playback compatibility and doesn't require on special hardware or software on the user end.
Rimage Video Protect™ (RVP) is a form of Content Alteration. It guards against unauthorized copying and ripping of DVD content by encapsulating data files in areas of the DVD disc that are not read during playback. This solution not only leaves playback compatibility uncompromised, but it also leaves the original media content unmodified.
Since RVP™ is a passive form of protection is does not require the player or content to be loaded with tracking software or heavy code. This also means that a minimal amount of space is required to utilize the protection, allowing a maximum amount of space on the DVD for the original content. Typical requirements range from about 5% - 9%.
