DVD Cutting Master Format Specification

Technology > DVD Cutting Master Format Specification

1.0 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 consists of a maximum six kinds of files named DDVID.DAT, T5TXT.DAT/T5 Text Stream, VOBTBL.DAT/VOB Location Table, COPYPROT.DAT copy Protection Information File, 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.

Figure 1-1: DDVID.DAT File Protocol

DDVID

(Mandatory)

DDVMS

for T5 Text File

(Strongly recommended)

DDVMS

for VOB Location Table

(Mandatory*)

DDVMS

for Copy Protection Information

(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 under the following conditions:

Whenever CSS is to be used on the current layer being described.

When, on the current layer being described, the DVD Image (IMAGE.DAT file) is stored in 2048 byte sectors and the byte 0 of the CPR-MAI field on the DVD Disc to contain non zero data.

When, on the current layer being described, the DVD Image (IMAGE.DAT file) is stored in 2048 byte sectors and the CPPM System is used requiring the byte 0 of the CPR-MAI field on the DVD Disc to contain non zero data.

Otherwise the DDVMS packet for the VOB Location Table file should not be in the DDVID.DAT file.

**Note: The Copy Protection Information file is required only when the CPPM encoding is to be performed on any layer of the disc during the physical disc formatting stage. Otherwise it is not allowed under this specification. If CPPM is to be placed on one layer, then this file is required for both layers.

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.
