Windows Media DRM or WMDRM, is a digital rights management service for the Windows Media platform. It is designed to provide delivery of audio or video content over an IP network to a PC or other playback device in such a way that the distributor can control how that content is used.
AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard (AES). Title keys are decrypted using a media key (encoded in a Media Key Block) and the Volume ID of the media (e.g., a physical serial number embedded on a pre-recorded disc).

The sandbox was also designed to frustrate the ability for services and the DRM to uniquely track and identify devices.
the encryption of keys for the authentication handshake. In order to decrypt a DVD-Video, the player reads the disc-key-block and uses its player-key to decrypt the disc-key. Thereafter, the player reads the title-keys and decrypts them with the disc-key. A different title-key can be assigned for the Video Manager and for each Video Title Set ...
