CNet is covering a press release from Western Digital which announced a new consortium called Secure Content Storage Association (SCSA) to create standards for transferring restricted / locked contented between storage and playback devices. From those two articles, it's difficult to say what details might be, but the UltraViolet (UV) keyword gives a clue:

"UltraViolet (UV) is a digital rights authentication and cloud-based licensing system that allows consumers [...] to stream and download purchased content to multiple platforms and devices.

...

UltraViolet content is downloaded (or streamed) in the Common File Format, using the Common Encryption (CENC) system."

However, currently it seems UV is all cloud and streaming based, with no option to transfer locked contented off-line. Enter Western Digital. Presumably, they will provide special hard-drives which can store and restrict the content, and only allow read and copy operations under certain conditions. Possibly using TPM or similar technology, but embedded in the drive itself.

Further down in the Wikipedia article, this bit is interesting, and again, the storage aspect is the noticable missing piece:

"UltraViolet selected five DRM technologies allowing restrictions management on a broad range of devices: televisions, set-top-boxes, DVD & Blu-ray players, games consoles, PC, tablets and smartphones. The selected DRM technologies are:

  • Google Widevine DRM, chosen for its strong position on set-top boxes
  • Marlin DRM, chosen for its compatibility with many Connected TVs
  • OMA CMLA-OMA v2, chosen for its strong position on mobile devices
  • Microsoft PlayReady, chosen for its wide availability on PC and CE devices
  • Adobe Flash Access 2.0, chosen for its wide availability on PC"

It's also interesting to see the rest of the list of companies supporting this, in the Digital Entertainment Content Ecosystem (DECE LLC) is a consortium. Nothing too surprising there, I guess, except for Tesco. (What will happen if your veggies are digitally restricted?)
