CHAPTER 4: DECLARATIONS AND SAFETY STATEMENTS
DVD-ROM Drive Information
The Mobile System comes with an optional DVD-ROM drive or a CD-ROM drive. In
order to view DVD titles, you must install your own DVD viewer software. Optional DVD
viewer software may be purchased with this Mobile System. The DVD-ROM drive allows
the use of both CD and DVD discs.
Regional Playback Information
Playback of DVD movie titles involves decoding MPEG2 video, digital AC3 audio and
decryption of CSS protected content. CSS (sometimes called copy guard) is the name
given to the content protection scheme adopted by the motion picture industry to
satisfy a need to protect against unlawful content duplication.
Although the design rules imposed on CSS licensors are many, one rule that is
most relevant is playback restrictions on regionalized content. In order to facilitate
geographically staggered movie releases, DVD video titles are released for specifi c
geographic regions as defi ned in “Region Defi nitions” below. Copyright laws require
that all DVD movies be limited to a particular region (usually coded to the region at
which it is sold). While DVD movie content may be released for multiple regions, CSS
design rules require that any system capable of playing CSS encrypted content must
only be capable of playing one region.
NOTE: Photos and icons in this manual are used for artistic purposes
only and do not show what is actually used in the product itself.
NOTE: The region setting may be changed up to fi ve times using the
viewer software, then it can only play DVD movies for the last region
setting. Changing the region code after that will require factory
resetting which is not covered by warranty. If resetting is desired,
shipping and resetting costs will be at the expense of the user.
