DVD
forum did a presentation of recent standardization work and future
roadmaps for the organization's formats at a conference held
in Tokyo yesterday. On the agenda were of
course the HD DVD format but also faster DVD-R DL and DVD-RAM speeds as well as
information about the DVD-RW DL format:
HD DVD will get a
second rewritable format called HD DVD-RR, as in ReRecordable. The
previously announced HD DVD-RW format is more or less like an HD DVD-RAM
format while the HD DVD-RR format will share more properties with the HD
DVD-R/ROM formats. Supposedly HD DVD-RR will be easier to make in a DL
version than HD DVD-RW too. The names are quite confusing though…
Region coding, managed
copies and AACS were also topics discussed. Region coding will not be a
part of AACS and might not be incorporated to the HD DVD format at all.
The specifications for AACS are not final yet so exact details of how
managed copies will work were not disclosed.
16x DVD-RAM was also
approved in September. The media will only be compatible with 6x and
higher speeds and hence not be writable with any of the current DVD-RAM
burners.
Draft
version 1.9 of DVD-RW DL specifications are under development and the
final 2.0 version is expected to be ready in late Q1 or early Q2 next
year. The write speed in the basic specifications will be 2x. The
presented specifications for DVD-RW DL show however a reflectivity of
only 5-10 % which is way below the 18-30 % required for matching the
DVD-ROM DL
specifications.
