Coral Consortium

The Coral Consortium seeks to ensure interoperability so that today's digital music and video can be easily accessed and enjoyed, regardless of the service provider or the device. While recent innovations in digital media distribution provide consumers with new channels to acquire music and video, proprietary differences still exist in underlying DRM or content protection technology. At times, these technologies conflict and prevent consumers from playing content packaged and distributed using one DRM technology on a device that supports a different DRM technology.

Digital Transmission Content Protection over Internet Protocol (DTCP-IP)

DTCP-IP is a specification for the protection of copyrighted content that is transferred over a digital home network. Under this specification, digital content can be shared securely between devices in a user’s home but not shared with third-parties outside the home network.   DTLA is the licensor of DTCP-IP.

Marlin DRM

Marlin is a DRM-based content sharing platform for consumer devices and multimedia services that is based on open standards. The Marlin core system provides seamless functionality when moving license content across different devices and services in a consumer domain.

Intertrust Technologies Corporation, Panasonic Corporation, Royal Philips Electronics, Samsung Electronics, and Sony Corporation originally developed Marlin DRM in 2005.

Microsoft DRM (PlayReady, WMDRM-PD, WMDRM-ND, COPP)

Windows Media Digital Rights Management (DRM) is a proven platform to protect and securely deliver content for playback on computers, portable devices, and network devices. The latest version offers increased flexibility to support a wide range of business models that provide consumers with even greater access to protected audio and video content.

Microsoft PlayReady

Microsoft PlayReady technology is optimized for the mobile industry to support the growth of online content services, and includes features designed to make it easier than ever for consumers to enjoy mobile digital entertainment.

Microsoft Windows Media DRM 10 for Portable Devices (WMDRM-PD)

WMDRM-PD enables the secure delivery of protected content for playback on portable devices such as mobile phones and personal media players.

Microsoft Windows Media DRM 10 for Network Devices (WMDRM-ND)

WMDRM-NDT/NDR enables the secure delivery of protected content for playback with a home entertainment network.

Protected Video Path - Output Protection Management (PVP-OPM) and Certified Output Protection Protocol (COPP)

PVP-OPM and COPP are Microsoft protocols that authenticate graphics drivers and ensure that copy protection is reliably signaled to the graphics adapter.

Open Mobile Alliance Digital Rights Management (OMA DRM)

OMA DRM specifies the end-to-end protocol for the distribution of protected content to devices. The OMA DRM security protocols are built upon a PKI infrastructure and require that both the Rights Issuer and the Devices have access to private keys, certificates and trust anchors.
