DRM platform owned by Google which combines DASH, CENC and EME to provide multiplatform content protection.

Widevine is a google company which provides a platform for delivering protected content and defend the copyright of the content.

In order to achieve the highest possible quality they use DASH (Dynamic Adaptive Streaming over HTTP). Using CENC (Common Encryption) which is in-line with other DRM providers regarding the license structure - such as PlayReady from Microsoft.

The device side of the Widvine solution is the CDM (Content Decryption Module) and EME (Encrypted Media Extension). The CDM is responsible for acquiring the content keys for decryption and securely delivering the output to the device’s firmware/hardware. The EME provides a JavaScript API that enables web applications to interact with content protection systems (e.g. the CDM), to allow playback of encrypted audio and video.

Widevine also maintains a license server which allow clients to access in order to get the license. Key management for the content can be done on Widvine platform or by the clients.

Widevine current version is 7.0 For more information see: http://storage.googleapis.com/wvdocs/Widevine_DRM_Getting_Started.pdf
