Physical Specification
Concept;
Specific
Media Type and Drive is not defined in this specification sheet.
In order to keep data compatibility between media, basic physical
specification is defined.
Media
Type;
This
document specify a protocol for sequential access media such
as a Tape. A protocol for other media type is reserved.
General
File Protocol;
The
DVD Cutting Master consist of maximum five kind of files named
DDVID.DAT, T5TXT.DAT/T5 Text Stream, VOBTBL.DAT/VOB Location
Table, CONTROL.DAT and IMAGE.DAT which shall be located in this
order. The file named DDVID.DAT consist of two kind of data
packet named DDVID and DDVMS. The content for these files and
packets is defined in this specification.
The
following figure 1-1 outlines the DDVID.DAT data file protocol
which is recorded on the media in this order, including packet
sequence and its packet name, that is required in this specification.

DDVID
(Mandatory)
|
DDVMS
for

(Strongly
recommended)

DDVMS
for

(Mandatory*)
|
DDVMS
for
CONTROL.DAT
(Mandatory)
|
DDVMS
for
IMAGE.DAT
(Mandatory)
|
Note: The
packet of DDVMS for T5 Text file is strongly recommended
*Note: The
VOB Location Table file is mandatory only when CSS is to be
used. If CSS will not be used, then the DDVMS packet for the
VOB Location Table file should not be in the DDVID.DAT file.
The
DVD data for one layer or one side is stored on each media.
Therefore, a double-sided or dual-layer application will require
two (2) separate media, each conforming to DVD Cutting Master
Format.
The
following figure 1-2 outlines the general file protocol, including
file sequence and file name, that is required in this specification.

*Note: The
VOB Location Table file is mandatory only when CSS is to be
used. If CSS will not be used, then the VOV Location Table file
should not be on the media.
File
Specification in case of Tape Media;
Tape
File System; ANSI Tape Labels
Tape
File Protocol; Five files of DDV data are separated by ANSI
Tape Labels as shown in Figure 1-3, including file sequence
and file name, that is required in this specification.

Note: The
file of T5TXT.DAT is strongly recommended.
Note: When
the file of T5TXT.DAT is deleted, related ANSI Tape Labels,
such as HDR1, HDR2, FM, EOF1 and EOF2, must be deleted.
Note: When
the file of T5TXT.DAT is deleted, the data packet of DDVMS for
T5TXT.DAT in the DDVID.DAT file should be deleted.
Note: When
the file of VOBTBL.DAT is deleted (when the DVD image shall
not have CSS), related ANSI Tape Labels, such as HDR1, HDR2,
FM, EOF1 and EOF2, must be deleted.
Note: When
the file of VOBTBL.DAT is deleted, the data packet of DDVMS
for VOBTBL.DAT in the DDVID.DAT file should be deleted.
