example of how a content may be organized:

Music

Multi-x (languages, subtitles, angles and aspect ratios)
DVD-Video supports the multi-x feature, which include multi-languages, multi-subtitles, multi-
angles, and multi-aspect ratios. These features are made possible because of the capacity a DVD
disk can hold.
DVD-Video also employs information control function, such as:
Parental Control
The Parental Control feature allows for up to eight levels of censorship. Different countries
set their own control levels. A DVD system should be designed so that changing Parental
Control levels requires a password.
Copy Protection
There are three different types of content protection:
Videotape (analog) copying is protected by the Macrovision 7.0 type circuit contained
in most players as an Analog Protection System.
DVD disks contain information regarding whether the contents may be copied.
The serial copy generation management system (CGMS) is designed for copy
protection information to be embedded in the disk.
Content Scrambling System (CSS). This copy protection prevents media files from
being read.
Regional Code Protection:
Currently, there are six different regional codes worldwide. Please refer to the DVD
references for determining your region code.
