SD Separate Delivery (CPRM Mandatory)

SD Separate Delivery (SD-SD) enables flexible distribution to manage a variety of content while protecting copyrights. In the SD-SD, the content key and content data can be treated separately. SD-SD supports the following distribution schemes.

  • Writing data at kiosk terminals
  • Pre-loaded content
  • Download and recording
  • Key download

The SD memory card can be used as a key storage dongle, as well. Only keys are stored in the SD memory card. A user can play back content data in devices only when the SD memory card is inserted in the device.

SD-SD provides several content format profiles. Some profiles have compatibility with the corresponding SD Application, such as between SD-SD Audio and SD-Audio. SD-SD Audio content can be exported as content in SD-Audio format.
