Traditionally, digital content has been protected with encryption. A digital rights management (DRM) system, using a secret key, encrypts content to make it unwatchable so that only somebody who has the key can decrypt and watch it. But that key, like all digital information, is easy to copy and share so on its own it is not sufficient to protect the content.
This was initially software-based, i.e., trying to stop people copying computer games and operating systems. As music, film, television and sports moved into the digital world, rights holders needed to find lightweight, non-intrusive and effective DRM technology solutions to protect their intellectual property.
The same DRM principles apply for any kind of video-enabled devices including smartphones, computers, tablets and gaming consoles.
