Revision Content
Digital Rights Management (DRM) is technology that enables online video and audio services to enforce that the content they provide is used in accordance with their requirements. This technology may restrict some of the things you can do in the browser. While some DRM-controlled content can be viewed using the Adobe Flash or Microsoft Silverlight plugin, many services are moving towards HTML5 video that requires a different DRM mechanism called a Content Decryption Module (CDM).
