The past year was, like 2005, another slow one for DRM standards. Much
of the activity was in the area of consortia controlled by certain segments of
the content and consumer electronics industries.
The "media player" axis of consumer electronics companies -- which includes
Panasonic, Philips, Samsung, Sony, and others -- was most active in developing
new standards. The two that they are backing are Marlin and Coral, and
they are complementary. Marlin is a spec for a DRM technology intended for
use with connected portable devices. It is based on some very elegant R&D
done by Intertrust -- the DRM technology company jointly owned by Sony and
Philips -- that uses graph theory instead of rights expression languages to
determine what rights a particular combination of user and device has to a given
body of content. The first complete
Marlin spec
issued in May, and a
trial in Japan
(part of an IPTV trial) will take place early this coming year.
DRM Interoperability Standards
Coral is a DRM interoperability standard based on the same underlying
messaging technology as Marlin, a technology also developed by Intertrust and
known as NEMO. Coral is a practical approach to DRM interoperability; it is
meant to be used by service providers that have an incentive to offer it, such
as customer lock-in or cross-sell. The first
public Coral
spec was published in June, and shortly thereafter, the Coral working group
published a
white paper showing how Microsoft Windows Media DRM can interoperate with
Coral "out of the box," i.e., with no changes to the technology. This is
an important result; the Coral group has already shown interoperability with
both Marlin and OMA DRM.
The major obstacle to Coral's market uptake is the lack of cooperation from
Apple -- which, of course, does not make its iTunes and FairPlay technology
available (or even visible through published APIs) to anyone else. It is
possible that Jon Lech Johansen's DoubleTwist technology will solve this
problem; see our
year-end DRM technology review for more on this. Still, a lot of
interest is building in Coral: its membership now totals 35 organizations,
including all four major music companies, three major movie studios, the RIAA,
IFPI, NARM, IFPI, and many consumer electronics companies in addition to several
DRM-related technology vendors.
Besides Apple, the other missing piece in Coral is the participation of
service providers that could build Coral-compliant services. The current
membership only lists two major ones: AOL and Time Warner Cable, both
subsidiaries of the media giant Time Warner. No other ISPs, telcos, or
cable companies are involved. This does not bode particularly well for Coral as
it moves into 2007 -- a year in which it needs to find uptake among service
providers, lest it lose its considerable momentum.
The two other DRM interoperability standards initiatives that had activity in
2006 were the Digital Media Project (DMP) and Sun Microsystems's Project DReaM.
DMP released its second major spec,
IDP-2, back
in May. IDP-2 finally showed DMP's approach to interoperability, something that
was inexplicably missing from the first spec (IDP-1) the previous year.
The IDP-2 approach is the converse of Coral. Instead of providing
interoperability among existing DRM technologies, as Coral does, IDP-2 is a spec
for a new, device-centric DRM that includes a small amount of required core
functionality and enables particular devices to include extended DRM features.
The idea is that everyone should adopt IDP-2 and choose the set of DRM features
that makes the most sense for any particular device.
The IDP-2 spec is an elegant piece of work, but DMP continues to suffer from
the same problems as before: an idealistic bent and a membership list that
includes no major content providers and only a couple of major consumer
electronics vendors. On reflection, we find that the IDP-2 technology is
conceptually similar to the Octopus DRM toolkit technology from Intertrust that
forms the basis (along with NEMO, as mentioned above) for Marlin. This is
somewhat ironic, given that Marlin is positioned as a single DRM solution, not
an interoperability standard.
Sun's Project DReaM (DRM/everywhere available) originally had the Quixotic
goal of being a spec for interoperable DRM that would both be developed on a
community-source basis and avoid reading on the existing DRM intellectual
property. Recent activity on Project DReaM shows a much more modest goal:
an open-source, royalty-free conditional access technology for IPTV systems
called DReaM/CAS. The other spec being developed by the DReaM group, a
more ambitious technology called DReaM/MMI (for "Mother May I"), did not --
unsurprisingly -- get a clean bill of health in a
patent coverage review (by an unnamed legal authority) commissioned by Sun.
The DReaM/CAS spec may well be of interest in the nascent market for IPTV
security, which is fragmented among several small vendors, as we mention in our
year-end technology review. At a minimum, the availability of an
open-source solution could reduce prices of the proprietary technologies; if the
technology is successful, those vendors could even morph into providers of
value-added implementations of DReaM/CAS. For this to happen, video
content providers must approve the technology, which has not happened yet.
Mobile DRM Standards
2006 saw two standards-related points of movement in mobile DRM. It has
now been over a year since the first OMA DRM 2.0-based content service
launched; no
others have followed suit. The word of mouth around OMA DRM 2.0 among handset
makers and wireless carriers is now so
negative
that we believe only a miracle can save it from oblivion. That miracle may
come from the DVB-H (Digital Video Broadcasting for Handhelds) community in
Europe, which is gearing up to launch a number of services into production next
year, but it is more than equally possible that DVB-H will become a vehicle for
conditional access technology from vendors like NDS, Nagravision, Thomson, and
Irdeto.
At the same time, OMA DRM 1.0 continues to proliferate; estimates put the
global installed base of devices that are OMA DRM 1.0 compliant -- or can be via
over-the-air software downloads -- at as much as half a billion. Yet
questions over "patent overhang" -- the applicability of DRM-related patents
from companies like ContentGuard and Intertrust to OMA DRM 1.0 implementations
-- remain unresolved, as do concerns about implementation complexity. The
patent pool for OMA DRM 1.0 implementations put together by the patent licensing
organization MPEG LA last year appears to be dead, as no progress in
negotiations with the wireless industry on licensing terms has been made in over
a year and a half, and MPEG LA has been focusing on Blu-ray and other fronts.
The other mobile DRM standards activity came from Melodeo, a Seattle-based
provider of proprietary mobile content delivery infrastructure whose customers
have included Telefónica Móviles
de España and Rogers Wireless of Canada.
As we mentioned in our
year-end review of DRM-enabled content services, Melodeo
is now focusing on MobilCast, its mobile podcasting service. Back in June,
Melodeo made its mobile DRM technology available to third parties under the name
PachyDRM,
positioning it as an open standard. In reality, the PachyDRM spec is
available on an open-standard basis, but the source code carries a licensing fee
of US $0.05 per device -- admittedly much cheaper than, say, Windows Media DRM
for Portable Devices -- and no indemnification for any patents on which it may
read. To our knowledge, PachyDRM has had no takers thus far.
AACS
The major new standard of interest to the film industry is Advanced Access
Content System (AACS), which is backed by IBM, Intel, Microsoft, Panasonic
(Matsushita), Sony, Toshiba, Disney, and Warner Bros. AACS is a grab-bag
of content protection technologies that has been adopted by both of the factions
in the high-definition optical disc format wars, HD DVD (backed by Toshiba) and
Blu-ray (backed by Disney and Sony). AACS appeared to be a major success
in that it eschewed the essential problems of DeCSS security for DVDs: it is a
much stronger, flexible, and more comprehensive DRM scheme, and the consumer
electronics industry agreed to adopt it apparently without any subsidies.
Yet AACS already seems a bit frayed around the edges. CE vendors have
devices supporting both formats on the market, and although sales were slow this
year, they are expected to grow significantly in 2007 as consumers bought HD TV
sets in droves this holiday season (ours is a Sony Bravia!) and will presumably
want sources of worthy content for them in the coming year. The problem is
that the spec is not finalized; even so, device makers have been selling players
that do not implement a few of the features, such as
digital output
resolution control. The lesson here for film studios is that they can
succeed in demanding a host of content protection features to be built into
consumer electronics before they will agree to license their content for use in
those devices, but those features must be chosen rationally according to
implementation practicality.
Creative Commons
Our final note on standards concerns the open rights management standard that
could turn out to be the one true success story of the decade: Creative Commons
(CC). Although CC is a product of the so-called "copy left" academic axis
and has been associated with many diatribes against the media industry and DRM,
it is really a standard for expressing certain types of rights that a content
publisher wishes to grant others. Some of the terms in CC licenses can be
enforced proactively through technology.
No less an organization than Microsoft has seen CC's potential and acted on
it. In June, Microsoft issued a
free add-on to
Microsoft Office applications that lets users insert CC licenses into their
Word, Excel, and PowerPoint documents with simple menu selections.
Then more recently, a startup called
Lisensa
announced a service that will license RSS feeds of blog content using a
combination of CC and commercial licensing terms. The person behind
Lisensa is associated with the Berkman Center at Harvard Law School, a bastion
of the copy left. Creative Commons has attributes in common with OMA DRM
1.0 that may well lead to its success as a rights management standard: it is
simple (not over-engineered) and it applies to a very interesting emerging
market (consumer created content). As we head into 2007, we expect more
stories like Lisensa to appear that enhance CC's appeal in the real world of
digital content rights and commerce.
