CableLabs has approved Real Networks’ universal Helix DRM solution for OpenCable Unidirectional Receiver (OCUR) devices connected to new PCs. Real’s Helix DRM will enable the secure delivery of content to the media center PC environment through CableCARD removable security modules. The OCUR device receives encrypted digital cable content from the CableCARD and then re-encrypts that content with Helix DRM. The secure IP output of the OCUR follows CableLabs’ “Digital Receiver Interface” (DRI) protocol specification, which allows connection to compliant PCs that also have Helix DRM.
Helix DRM is a comprehensive and flexible platform for the secure media content delivery of standards-based as well as leading Internet formats, including RealAudio, RealVideo, MP3, and MPEG-2, AAC, H.263 and AMR. It is the second DRM system to complete the due diligence necessary for approval by CableLabs for use with the OCUR and PCs. Prior approvals of digital rights management systems and secure digital output and recording technologies include DTCP over IEEE-1394, HDCP over DVI and HDMI, WMDRM over DRI, and VCPS and CPDO for optical media recording and hard drive storage, respectively.
