What Is CSS
CSS here is short for Content Scramble System that is a common encryption scheme used on DVD-Video discs. It can be considered as an advanced regional restriction. The aim is to prevent discs being read, analyzed and copied for illegal purpose. It is similar to other DVD copy protections or digital rights management (DRM) systems like region codes, DVD-Cops, Burst Cutting Area, ProtectDisc Video and LaserLock.
CSS can be applied on a player (hardware) to encrypt the playback protection, a drive to prevent reading disc data or a disc to deny the accessing unless a secret key or authentication is provided.
What Is CSS Protected DVD
A CSS protected DVD is always a commercial DVD that is encrypted with CSS. Specifically, a title key is embedded in small sections of all Packs of the disc.
