2.1 Restrictions for content in the DVD-Video zone

2. DVD CPRM Downloadable Video Contents

2.1 Restrictions for content in the DVD-Video zone
Content in the DVD-Video zone shall be used to provide a courtesy message and may be used for otherpromotional or educational purposes that are within these guidelines. Because existing players are not able
to handle contents in DVD-DC zone, the DVD-Video zone is only intended to be played back on existing(legacy) DVD-Video players.
The usage of content in DVD-Video zone is limited, therefore it is required that the content be created as asequential title with no branching. The DVD-Video zone’s playback order shall start with the courtesy
message followed by other content (if any) without any branching by navigation commands or by user
operation. When playback of the content reaches the end of the DVD-Video zone, the content shall becreated to either stop or automatically repeat from the beginning of the courtesy message.
A users operation during the playback of the content is possible if the content does not prohibit it. Sinceuser operation for skipping a chapter is limited within a PGC or within a Title, it is strongly recommended
that the content is created as a sequential PGC and at least shall be created as a Title, since the user function
to skip the chapter is mandatory within a PGC (PrevPG_Search( ) and NextPG_Search( )) and is optional
within a Title (PTT_Search( )).
Total playback time of the DVD-Video zone content is strongly recommended not to exceed 10 minutes.
In addition to the details defined above, the following restrictions shall be applied to the DVD-Video zonecontent:• No menus shall be called by navigation command or user operation.
Æ VMG menu and VTS menu shall not exist.
• Only one title shall be allowed for the DVD-Video zone title.
Æ The number of VTS shall also be one.
Note : Since one VTS shall be allowed for the DVD-Video zone title, the attributes ofeach Video Object such as video or audio codec, aspect ratio of video, number ofaudio channels or others shall be same for all objects within a title if two or moreVideo Objects exist in the DVD-Video zone title.
• Parental control shall be prohibited in the content.
Æ No PGCs shall exist in a PGC Block.

2.2 How to create the Title in DVD-Video zone

2.2 How to create the Title in DVD-Video zone
As defined in 2.1, the title in DVD-Video zone shall be a sequential title.
When a disc which includes DVD CPRM Downloadable Video titles is inserted in a DVD-Video player, theplayback of the DVD-Video zone title is automatically started if the DVD player supports DVD writable
media. The DVD-Video zone title shall then be played back to the end of the DVD-Video zone title
without any branching, if there is no user operation.

In order to realize this behavior;• First Play PGC which includes a command to automatically start the playback of Title#1 (JumpTT #1(TTN = 1)) shall exist.
Once the playback of the DVD-Video zone title reaches the end, the playback shall be stopped or shall berestarted from the beginning of the DVD-Video zone title. In order to realize this behavior;• The "Exit" command shall exist in the Post-Command (POST_CMD) Area in the last PGC of the title
and/or• The commands to restart from the beginning of title, such as "LinkTopPGC (in case that the title iscreated by one PGC)" or "LinkPGCN#1 (in case that the title is created by two or more PGCs)", shallexist in the Post-Command (POST_CMD) Area in the last PGC of the title.
There are several ways to create Video Object(s) for a DVD-Video zone title and to map each logical unit
defined in the DVD-Video specifications. The following is three typical examples:a) The DVD-Video zone title is created and only used for a courtesy message (refer to [Figure2.2-1])¾ One Video Object is created and¾ The Video Object is mapped to a Cell/a PG/a PGC.

Version 1.03. Image data onto a Dual Layer disc

3. Image data onto a Dual Layer disc

When image data is created for a Dual Layer disc, the Last address of Data Recordable area on Layer 0 of thedisc is needed, as this address may be different for each disc.
There is a requirement that a Cell shall be allocated on the same layer and two Cells which are presented
seamlessly shall be allocated on the same layer.
Therefore, if two Cells presented non-seamlessly are recorded across the layer, the DVD-DC zone shall beallocated in the image data so that the end of the first Cell shall be aligned at the end of Data Recordable areaon Layer 0 using the Last address of Data Recordable area on Layer 0 of the disc. When the allocation ofthe DVD-DC zone is changed, related data in Volume and File Structure shall be changed.
See [Figure 3-1].

It is strongly recommended that the courtesy message, promotionaland educational content (if any) in the DVD-Video zone should be used to provide information that helps
DVD-Video consumers experience consistent playback of DVD CPRM Downloadable Video content
protected by CPRM.
Content and service providers are encouraged to provide other informational resources, in addition to thecourtesy message, that consumers can easily access for additional information about DVD CPRM
Downloadable Video protected by CPRM, related products or services.
Content providers shall provide a courtesy message in the DVD-Video zone. For this purpose, content
providers may wish to consider the following as an example of a courtesy message.
