|The DVD Forum has developed new DVD Specifications
"DVD Download Disc for CSS Managed
which specify a write-once media to record CSS encrypted DVD-Video
contents via download.
The DVD-Download disc employs 2x wobble signal and CSS applicable
Lead-in area, which generally differs from the DVD-R for General
Since the DVD-Download disc is a derivative of the DVD-R for
General disc, the DVD Forum has decided to define the DVD-Download
Specifications as an Optional Specification
of the DVD-R for General Specifications initially. In
the future, it is planned that the DVD-Download Specifications,
with any improvement or update of the specifications, will become
a new Main Book that is independent
of the DVD-R for General Book.
Considering the future upgrade to the Main Book of new category,
DVD Forum and DVD Format/Logo Licensing Corporation have also
decided to establish the Format/Logo License for DVD-Download
independent of the License for DVD-R for General starting
from the issuance of the Optional Specification.
Therefore, the Optional Specification Book "DVD Download
Disc for CSS Managed Recording" is not attached to the
DVD-R for General Book, but provided separately from the DVD-R
for General Book at $500 per copy. The subscribed Optional
Specification Book will be upgraded to the Main Book without
extra charge, when it is issued.
Please note that DVD-R for General Book is not necessary to
obtain the Format/Logo License for DVD-Download.
Your understanding will be appreciated.
