Multiple Screen Conditional Rights Managements – DRM for TV, PC, and Mobile Video
Different types of devices require the use of multiple types of digital rights management systems. Francois Saint-Martin from Viaccess explained to me during IBC that TV broadcasters that are expanding their systems to provide three screen content (TV, computer, and mobile) need to use multiple types of digital rights management (DRM) systems. These include open mobile alliance (OMA) and Microsoft rights management. OMA DRM 1.0 is embedded within many mobile phones and recognized by music distributors as a protected download system. OMA DRM 2.0 is embedded in the newer mobile phones and is recognized by movie studios as a protected distribution system for video and multimedia content. Microsoft media digital rights management (WMRM) is part of personal computer operating systems and is recognized by music distributors and movie studios as a protected distribution system for music, video, and multimedia content. The rights management systems used by TV broadcasters should be able to use and integrate these DRM systems with their existing rights management system.
