Cutting Master Format Specification
(1) Purpose of DVD_CMF.
DVD_CMF (Cutting Master Format) is a standardized way of communicating
and transferring data between DVD title authoring workstations
and DVD glass master cutting systems. DVD_CMF will contain the
final "DVD Image File" as well as certain descriptive information
that is required by DVD glass master cutting systems to perform
the final DVD Encoding steps, including lead-in, lead-out and
middle area data generation, compute proper DVD error correction
and add optional DVD CSS. DVD_CMF also contains information
concerning desired DVD Layer and Side which are used by the
Laser Beam Recorder to establish required rotation and translation
DVD_CMF can be used to describe DVD Image Files on any carrier
that uses named files. This includes sequential access tape
devices that make use of ANSI tape labels, such as DLT (Digital
Linear Tape), SONY AIT (Advanced Intelligent Tape), Exabyte
8mm formats and D-VHS.
(2) Relation with DDP
DVD_CMF has been jointly developed by DCA and DVD Forum WG1/CMF
voluntary members primary based on DCA DDP as a derivative work
in consideration of CSS related.
DVD_CMF is technically equivalent to DCA DDP2.10 subset concerning
DVD, however the occurrences of "DDP" are changed and renamed
to "DDV" for DVD_CMF.
DDP, DDP 1.00, DDP 1.01, DDP2.00 and DDP 2.10 are trademarks
