Disc Description Protocol

Disc Description Protocol (DDP) is a format for specifying the content of optical discs, including CDs and DVDs.

DDP is commonly used for delivery of disc premasters for duplication. DDP is a proprietary format and is the property of DCA. The file format specification is not freely available.

The DDP must contain 4 parts:[1]

  1. Audio image(s) (.DAT file(s))
  2. DDP Identifier (DDPID)
  3. DDP Stream descriptor (DDPMS)
  4. Subcode descriptor (PQDESCR)

An optional text file can also be included, this will contain the track titles and timings.
