Working with digital rights management (DRM) to protect the video content can be a complicated task with the number of technologies and devices in use. The term DRM sends a panic signal to most of the technical leads, business analysts and developers. A lot of R&D is required to understand the DRM system and supported devices for different studio DRM.

Simply put, DRM ensures that video content is stored and transmitted in an encrypted form so that only authorized users and devices can stream the content. When a user device requests to stream a video, the video player requests a key from a license server, the licensing server determines whether the user and device are authorized to access the video content before issuing a license response with a decryption key, once the license is issued, encrypted file is transferred to the device and the player decrypts and streams the content for the user.
