Open Source Content Decryption Module now accessible

The Open Source Content Decryption Module has been developed by Fraunhofer FOKUS with the aim to be suitable and interoperable for as many systems and providers as possible. The code is now accessible for everyone on GitHub.

It is intended for OEMs, DRM providers, system integrators and browser ven-dors looking to enable playback of premium video content via EME.

The media transmission between a browser decoupled media engine and the Content Decryption Module interface specification (CDMi) can be secured via a DRM-specific authenticated interface. The CDMi itself contains most CDM logic and is a c++ wrapper for the embedded platform DRM.

This implementation offers interoperable HTML5 based protected video delivery, DRM interoperability based on Common Encryption (CENC) and MPEG-DASH support.

Dr. Stefan Arbanowski, director of Fraunhofer FOKUS‘ competence center „Future Applications and Media“ says: »We would be happy to see a broad adoption of our implementation and encourage contributions of OEMs, DRM providers, system integrators and browser vendors. A first end-to-end implementation has been done testing with a Microsoft PlayReady CDMi implementation. This CDMi allows open source browser vendors to support DRM without licensing it.«

OCDM is built with a modular concept in mind to be easily extendible and flexible. The open source code already provides support for the CDMi, which essentially requires the CDM to use the operating system's native Remote Procedure Call (RPC) mechanisms to forward EME calls.

»We are pleased with Fraunhofer FOKUS’ decision to publish an open source version of their HTML5 Content Decryption Module (CDM). This software will enable HTML5 browsers to deliver on the promise of internet enabled media, and will greatly expand the reach and footprint of premium content for content owners, service providers and OEMs«, says Chris Santini, Director of Strategy and Business Planning at Microsoft.

OCDM supports the Linux based Browsers and Platforms FAMIUM, Chromium, Opera, QtWebengine. Detailed information on how to build and run OCDM can be found on GitHub. The end-to-end prototype implementation for early technology evaluation and interoperability testing FAMIUM already integrates OCDM and a CDMi Implementation supporting Microsoft PlayReady.

The Open Source Content Decryption Module and its implementation will be shown at IBC 2014. Be invited to Fraunhofer FOKUS’ booth in hall 8.B80 and Microsoft’s booth in hall 13.MS1/2. IBC is taking place in Amsterdam on Sep-tember 12-16.
