The Academy of Motion Picture Arts and Sciences last week
endorsed technology from
the Cinea division of Dolby Laboratories to create and play back
specially-protected DVDs as part of the process of distributing "screener"
copies of films being considered for Oscar nominations. This will be the
Academy's solution to the problem of screener piracy that resulted in an uproar
in the season leading up to last year's Oscars. The Cinea technology uses a
fingerprint/watermark scheme that the company says can survive analog
conversion and even camcorder recording of movies on TV monitors.
The basic idea behind this solution is to fingerprint discs with the identities
of players as the discs are played. (This meaning of the word
"fingerprint" differs from another one that refers to technology that determines the identities of music tracks by examining
the actual digital content.) In addition to special DVD recorders that
create discs in Cinea's format, the technology requires special players that encrypt the
data and imprint it with the player's identity; therefore, any copies that
anyone makes will be traceable to the individual player. Special players will
need to be distributed to all Oscar reviewers, and the film studios will need to
pay for the special recorders.
This technique is quite similar to technologies already used in the music
industry for distributing promotional copies of albums and tracks to critics,
radio stations, and others who normally receive music before its public release;
companies like DMOD, Activated Content, MusicPoint, and Interoute have
technology or services for distributing music over the Internet in this way,
while some record labels are using SunnComm's copy protection technology for CDs for
the same purpose. It is impractical to send feature film content over the
Internet in this way, so any solution to the screener piracy problem would have
to work on physical media. (Despite that, the UK firm CyphaWare has an
Internet-based solution for secure digital video distribution.)
At the same time, the CSS encryption scheme for DVDs is woefully inadequate
to ensure security. A number of large technology companies submitted
proposals for watermarking-based DRM schemes for DVDs to the DVD Copy Control
Association a few years ago, but that process seems to have been stalled.
More recently, a handful of small firms have been developing this type of
technology, including First4Internet, USA Video Interactive Corp., SunnComm, and
Cinea, which was acquired by Dolby nearly a year ago. All else being
equal, it should be little surprise that the one of those firms with the best
existing Hollywood connections should obtain the Academy's blessing --
particularly because Dolby is heavily involved in the emerging world of digital
cinema, to which Cinea's technology could readily apply.
Although no film studios have formally agreed to use the Cinea technology to
distribute Oscar screeners, it is expected that many will; moreover, they will
need to pay Dolby for the recorders as well as a technology licensing fee.
(It is unclear whether or how the studios will pay for the screener viewers'
special DVD players.) It is interesting that the content industries are
subsidizing DRM schemes like Cinea's that are used for targeted-release content,
whereas they would not subsidize consumer technologies like CSS -- which was
designed by consumer electronics vendors with the presumed primary criterion of
low unit cost rather than effectivness. If they had done so, then the
piracy scenario for DVDs and other content formats would undoubtedly be much
different today.
