Disc Description Protocol

DDP identifies and describes collections of data that will be recorded onto a High Density (HD), DVD or CD optical disc. DDP was invented by Doug Carson and DCA to help manufacturers have a consistent and complete description of the input media for use in glass mastering of CD. DDP was extended to DVD in 1996, with High Density formats added in 2006, and continues to be licensed and kept current by DCA. The DDP license is free of charge, and requires only the completion of a license agreement and your commitment to keeping the standard consistent.

Effective March 2004, DCA was granted a registered trademark for DDP. DDP® is a registered trademark of Doug Carson & Associates, Inc. and is protected by U.S. Copyright. Disc Description Protocol and the DDP Logo are trademarks of DCA, Inc. Copyright© DCA, Inc. 2004-2008. All Rights Reserved.

DDP and CMF Comparison
The DVD Forum also sanctions CMF (Cutting Master Format), which is a derivative of DDP. This remains the case for HD-DVD ROM: CMF 2.0 is a subset of DDP 3.0. CMF for Blu-Ray (BD CMF) is not related to DDP, though it is DCA's hope that it also eventually will resolve under the existing industry standard DDP.
