Glossary of Terms
DDP stands for Disc Description Protocol. It is a format used to send technical information about the structure and contents of optical discs (CD, DVD, HD-DVD) to a replication plant. It was developed by Doug Carson and Associates, Inc. in 1989 and DCA, Inc. still owns the format. It is the industry standard for most optical media premasters. In the past, DDP images have been delivered on DLT (Digital Linear Tape) or Exabyte (another digital tape technology), but can now also be sent over FTP (File Transfer Protocol) or on another digital storage medium.
