CMLA actively supports numerous industry standardization efforts to ensure compatibility and extend CMLA support to new technologies for delivering premium entertainment content.

OMA Digital Rights Management

OMA DRM version 2 specifications define end to end protocols and methods for protected content distribution. OMA DRM is independent of media formats, operating systems, and runtime environments allowing protection of a wide variety of media objects.

The OMA DRM is the only major digital management rights system that was developed within an open industry standards forum with contributions from dozens of participants including device manufacturers, software companies, service providers, and content owners. CMLA supports up to the latest approved version of the OMA DRM specification, v2.1. more here
