Cnet Asia reports that a re-issue of the Terminator
2 DVD contains a new copy protection based on Microsofts Windows Media Digital
Rights Management. The protection is pretty restrictive and needs an internet
connection to do checks if you are allowed to playback the movie and if you are
on the right continent. Consumers that purchase the movie however get also a
normal DVD, the DVD-ROM is only an extra disc, the other movie is protected with
the normal CSS protection.
The protection also checks if only one person
is viewing the movie, if someone else with the same movie tries to connect he
will not be able to view it, this to prevent illegal copying.
The set
contains a standard DVD, but the DVD-ROM has a high-definition version
that provides three times more video detail, SyncCast spokesman David
Nichols told CNETAsia. The movie file is encoded in WM9 format, required
for the DRM operation of Windows Media Player 9.
The PC playing the DVD-ROM must be connected
to the Internet, so as to obtain a license. Content owners can decide
which type of license to issue; 1 time play, unlimited play, expires after
30 days, and so on, said Nichols. "In the case of T2, Artisan (the studio
releasing the DVD) decided to issue licenses that have to be renewed every
5 days. You can get as many 5 day licenses as you want but each license is
only good for 5 days," he said.
This allows, say, a notebook user to view the
movie for 5 days while on the road and disconnected from the
Web.
