Memorandum submitted by Electronic Frontier

OVERVIEW
A little-noticed standards body is crafting
a new regime of restrictions that will shape the future of television.
The Digital Video Broadcasting Project (DVB) is a standards-specifying
body that creates standards for digital television in Europe,
Australia, and much of Asia[16].
Consumerswho have not been consultedhave much to
fear from behind the closed doors of DVB.
In 2003, DVB stepped outside its usual domain
of specifying modulation schemes for satellite, cable, and terrestrial
broadcasts, and undertook a radically different work-item: specifying
a far-reaching system of use-restrictions on digital television
programming.
This specification is called Content Protection
Copy Management (CPCM) and it represents a grave danger to national
development priorities, social concepts of the family, competition,
customary public rights in copyright, and innovation.
When CPCM emerges from its DVB committees, it
will be presented to the European Telecommunications Standards
Institute (ETSI), the European standardisation body that turns
the DVB's specifications into standards. Thereafter, each nation
whose digital television system is based on DVB specifications
will be encouraged with all the lobbying pressure big US entertainment
companies can bring to bear to adopt regulations giving CPCM the
force of law. This is because CPCM is not free-standing and capable
of voluntary adoption by the private sector; it requires the force
of law to be effective[17].
Every nation that mandates DVB CPCM signs away
its citizens' rights, signs away the competitiveness of its technology
industry, signs away its domestic artists' self-determination,
and signs away its programmers' rights to innovate and publish
their work.
CPCM represents an unprecedented level of control
for entertainment companies over the technologies that let the
public enjoy and use lawfully received television programming.
Summary
DVB creates digital television specifications
for use in Europe, Asia, Latin America and Australia.
A DVB project called Content Protection
and Copy Management (CPCM) goes beyond the customary work of setting
television standards to set out specifications for restricting
how television programmes are used after reception.
CPCM represents a grave danger to
nations that mandate it as part of their digital television strategies.
ABOUT DVB, DIGITAL
TELEVISION, AND
THE BROADCAST
FLAG
DVB is a standards-specifying body for digital
television (DTV). As countries around the world undertake the
transition from analogue to digital television, various standards
bodies are formulating schemes for encoding, transmitting, receiving
and decoding DTV signals. Among other things, these bodies formulate
systems for broadcast "terrestrial" DTV (DTV signals
sent through the air from a traditional broadcasting tower), DTV
over cable and satellite, and DTV that is optimised for reception
on mobile devices, such as cellular telephones.
The transition to DTV is a policy priority through
much of the world. In nations that allocate spectrum rights by
auction, for instance, the electromagnetic spectrum used by analogue
broadcasters is viewed as a potential source of billions for national
treasuries, once it has been freed up from analogue TV transmissions
and sold on for use by mobile telephony and wireless data applications.
Alternatively, this spectrum could be productively given over
to unlicensed spectrum users as was done with the spectrum used
by WiFi devices.
But switching off analogue television transmissions
is fraught with political peril. An elected lawmaker who orders
analogue transmissions to cease before her constituents have purchased
digital receivers will find herself facing a great deal of political
unrest, as voters discover that their television sets no longer
work.
In the US, this problem has severely delayed
the analogue switch-off. The focus there is the attempt to lure
Americans to DTV with high-definition broadcasts that provide
some qualitative improvement over the old standard-definition
transmissions. Thus far, this value proposition has failed to
persuade a significant proportion of the American audience. This
failure has been politically exploited by entertainment firms
who induced to US Federal Communications Commission to adopt a
regulation known as the "Broadcast Flag", nominally
to spur the DTV transition.
In adopting the broadcast flag rule, the FCC
agreed to dramatically limit the functionality of DTV devicesto
prohibit features the motion picture studios characterized as
challenging their business modelsin the hopes that the
studios would release feature films and other popular programming
for terrestrial DTV broadcast. Though the studios drafted this
regulation and achieved its adoption through their lobbying efforts,
they never promised to provide any DTV programming in exchange
for the regulation; rather, they threatened to withhold DTV programming
if it were not adopted.
The Broadcast Flag relied on a signal that can
be embedded in any DTV programme, which, when detected, triggers
the use-restriction technologies that the studios wanted included
in DTV receivers. This signala simple "on" or
"off"is possible because the US DTV standard
set by the Advanced Television Standards Committee (ATSC, a rival
of the DVB) reserved a place in the signal for a "redistribution
control descriptor". This left a slot open for a legal mandate
and then the studios convinced the FCC, as the regulator, to fill
that slot.
In May 2005, the United States Court of Appeals
for the District of Columbia Circuit struck down the Broadcast
Flag regulation[18]
on the grounds that the Commission did not have the jurisdiction
to regulate what devices do after receiving a programme. In the
words of the court, "In the seven decades of its existence,
to FCC has never before asserted such sweeping authority. Indeed,
in the past, the FCC has informed Congress that it lacked any
such authority. In our view, nothing has changed to give the FCC
the authority it now claims." [19]
The studios have responded by floating a very
broad legislative proposal that will give the Commission "authority
to adopt regulations governing digital television apparatus necessary
to control the indiscriminate redistribution of digital television
broadcast content over digital networks".[20]
As of August 2005, this proposal has not been introduced in the
U.S. Congress. Legislators may be sceptical of it because of public
sentiment against the broadcast flag and because it could substantially
expand the Commission's jurisdiction.
DVB
DVB was founded in 1993 with the understanding
that it was embarking on a specific task: specifying a modern
digital television standard for use in Europe and beyond. This
standard would specify modulation schemes and other technical
elements of DTV systems up until the point of signal reception.
Once this standard was to everyone's liking, the DVB would wind
down or reconstitute to address new issues[21].
However, in 2003, the DVB embarked on a very
different sort of project. At the behest of the same Hollywood
studios that backed the US Broadcast Flag, the DVB embarked on
a project to build a system for restricting what owners of digital
television sets will be able to do with TV programmes after they
have received them.
This project is called Content Protection and
Copy Management (CPCM), and the DVB has put it centre-stage in
its plans for DVB 3.0, the forthcoming version of the DVB standard[22].
The scope of the US broadcast flag regulation was relatively narrowthe
redistribution control flag could only be present or absent. DVB
CPCM, by contrast, is specifying remarkably fine-grained and elaborate
means by which broadcasters can control the detailed functionality
of receiving devices. In effect, CPCM and its constituent specifications
amount to a complicated, lengthy, and, at present, secret body
of private law that describes rules and restrictions potentially
applicable to all manufacturers of DTV devices. It is already
clear that at least some CPCM co-authors expectand requirethe
co-operation of regulators to make this scheme obligatory upon
these manufacturers[23].
CPCM has taken up more and more of DVB's energies,
and has been the source of much controversy in the popular press.
Several Hollywood studio executives sit on the DVB steering committee.
At the same time, the body's focus is shifting from drafting technical
specifications to writing laws that prop up American companies'
business models as practiced abroad and at home.
Government intervention in DTV standards is
already ubiquitous. Governments have perceived a public interest
in seeing to it that every broadcaster who makes use of the public's
airwaves does so in a fashion that is robustso that a clear,
reliable signal may be receivedand that follows standard
formats so that those citizens who buy digital televisions can
be certain that their sets will receive local transmissions. Whether
or not this view of government's role in standardization is appropriate
today, state adoption of a terrestrial DTV standardand
the promulgation of accompanying regulationscontinues to
be the international norm.
This puts DTV standards into the narrow, special
class of standards that are backed by the force of law. Other
standardslike HTTP, which underpins the World Wide Web;
or ISO 9000, which specifies best practices for manufacturersare
voluntary. Businesses and inventors choose which standards they
will employ in order to yield the highest return on investment,
based on perceived marketplace demand, utility and cost of implementation.
In DTV contexts, though, the implementers of
receivers, transmitters and related devices are often required
to adhere to the standards set out by the national regulator.
A noncompliant implementation isn't merely noncompliantwhen
mandated, it is illegal. The traditional telecommunications regulator's
remit covers to use of the airwavesthe kinds of radio waves
a device can emit Broadcast flags are a new kind of mandate: a
mandate over what devices can do with radio waves after they've
been received in the privacy of your own home.
This is why CPCM is more a law than a standard.
It sets out to "protect business models"[24].
ATSC's more modest "redistribution control descriptor"
leaves a void that might be filled with a regulationat
DVB CPCM meetings, participants are boldly writing a regulation
aimed specifically at advancing one group of incumbents' business
model.
Is CPCM Necessary?
Global experience with digital television and
radio broadcasting suggests that CPCM is unnecessary. Digital
television is not inherently risky to rights-holders. Digital
redistribution of recordings of analogue television programming
is already ubiquitous, and there is no element of DTV that makes
it any easier to redistribute over the Internet.
Indeed, practically every single one of the
current analogue TV offerings is recorded and redistributed over
the Internet, suggesting that the "easy enough" point
has already been reached, and no further "progress"
in this field is necessary to enable more infringement or distributionthese
activities are already undertaken by everyone who cares to do
so. It is therefore hard to see how DTV can possibly increase
the practice of sharing of recorded TV programmes.
Even though every TV programme aired is freely
downloadable from the Internet, sales of classic programmes on
DVD are strong and growing year on year. Ironically, switching
to high-definition broadcasts may impede Internet redistribution,
rather than accelerating it, since:
It is harder to redistribute a high-definition
programme over the Internet (the large file size of a high-definition
programme makes it practically impossible to redistribute over
today's P2P networks witout substantial massaging to "down-rez"
(compress) it, a process that generally renders the file indistinguishable
from one recorded from analogue transmission).
A viewing public that is accustomed
to high-resolution transmissions will be less likely to substitute
a down-rezzed P2P download for an authorized, high-definition
version.
Overhanging these discussions is the spectre
of risk that the studios will make good on their threats not to
release their material for DTV transmission without an agreement
to restrict the features in DTV devices. This threat was oft-repeated
during the FCC's deliberation on the Broadcast Flag, and surfaced
as recently as the DVB World conference in March 2005 in Dublin[25].
The US experience shows that these threats are
not very credible, however. Viacom, parent company of the USA's
CBS told the FCC that it would cease to transmit DTV programming
in summer 2003 unless the Broadcast Flag mandate were operational[26],
yet years after the expiration of its deadline, CBS and other
Viacom subsidiaries have made no move to reduce or pull DTV programming.
Similarly, the studios roundly decried the BBC's move to transmit
unencrypted satellite signals and promised to stop licensing to
the BBCa threat they likewise did not make good on. In
fact, a quarter century ago, during the fight over the legality
of video cassette recorders (1976-84)[27],
the studios repeatedly promised never to release a single movie
on pre-recorded cassetteagain, a threat that crumbled in
the face of consumer demand.
The studios are businesses and they depend on
broadcast revenue to make their bottom lines. In general, with
or without the ability to control entertainment technologies,
the studios must license their programming for distribution if
they are to preserve their sources of revenue. Stepping out of
the market to attempt to control device design will never be a
plausible long-term strategy for studios who need customers to
survive.
Finally, even if the movie studios make good
on their threat to withhold content from digital broadcast, a
host of diverse new content producers wait in the wings to fill
any broadcast vacuum left by obstinate studios. In the US, for
example, HDNet has rapidly become one of the biggest producers
of DTV programming. Mark Cuban, billionaire founder of HDNet,
has repeatedly stated that he views restrictions like CPCM as
unnecessary to the success of his and other new DTV ventures.
In the US, luring consumers to a digital transition
via high-definition offerings has met with little success. By
comparison, the UK has adopted a "Freeview" strategy
through which consumers are lured to purchasing DTV receivers
with the promise that these receivers will give them up to 30
free standard-definition channels on their existing sets, for
life, with no subscription fees[28].
Free TV is more valuable than high-resolution TV. High-definition
TV is most properly seen as the icing on the cake, a way to lure
a few videophiles into the digital fold, not the core value-proposition
for a switch away from analogue.
In general, Europe's digital broadcast strategy
has relied more on the carrot than the stick. The UK's Digital
Audio Broadcasting (DAB) system is wide open, and anyone can build
a DAB receiver. There are numerous entrepreneurs, garage inventors,
and mainstream companies innovating in the DAB space, with recording
devices proliferating and readily available DAB support on the
PC[29].
By every metricprogrammes on the air,
revenue to studios, rate of consumer DTV adoptionthe European
carrot approach beats the American stick approach. DVB CPCM as
a policy proposal would thus mark a radical departure from European
norms, which are based on user-friendliness, technological openness,
and interoperability.
Summary
CPCM is the DVB's answer to the failed
American Broadcast Flag, an attempt to buy the studios' co-operation
with the digital TV transition by offering them control over DTV
devices.
The studios have no credible new
threat from DTV, nor is there any reason to believe that they
will avoid DTV in the absence of a CPCM regime.
It is crucial to keep CPCM from being
mandated in national laws.
CPCM OVERVIEW
The DVB CPCM specification is being developed
in closed-door meetings. Joining DVB costs 10,000 Euros per year,
and membership is only open to manufacturers, broadcasters, studios,
and academics. Its proceedings and intermediate work products
are not widely published or publicized[30].
Most of the details of CPCM have not been publicly
disclosed. The material in this section is drawn from two public
presentations, one given by the Motion Picture Association of
America's (MPAA) Vice-President, Jim Williams, at the DVB World
Conference in Dublin in March 2005[31],
the other given by DVB Content Protection Technical Group chairman
Chris Hibbert to the MPAA's Copy Protection Technical Working
Group in Los Angeles in January 2005[32].
CPCM is a system to "enable . . . current
& future business models"[33].
To accomplish this, CPCM employs three areas of specification:
Usage State Information (USI). This
is a set of commands that can be embedded in a TV programme. These
commands instruct a DTV receiver to apply particular restrictions
to the programme received by the device. Elements of USI include
"Copy Once" and "Copy Never", "Proximity
Control" and "View No More." The level of control
afforded by USI is particularly extensive and fine-grained compared
to the "rights expression" in older use-restriction
schemes. This more precise level of control is intentional and
regarded as beneficial by its authors.
Definitions. CPCM defines new terms,
"Authorised Domain" and "Local Environment."
The definitions of these terms effectively set the boundaries
of what a valid family is ("Authorised Domain") and
how far apart two devices are allowed to be in order to interact
("Local Environment").
Compliance rules. This is a set of
rules for DTV device manufacturers. They limit the choices manufacturers
can make in developing their products, and require them to implement
technological measures they might not choose to use otherwise.
CPCM is intended to form the basis of a regulatory
mandate throughout Europe, Asia, Australia, Latin America and
all other countries that adopt DVB specifications. As DVB Executive
and time Warner VP Spencer Stephens stated at DVB World, "[CPCM]
need(s) to be mandated and protected by regulation." [34]To
be effective, CPCM requires that more open and capable devices
be precluded from the market. Otherwise, there is a risk that
consumers would not purchase the less capable CPCM compliant devices.
This, in turn, requires national technology mandates, to outlaw
more capable devices.
As a result, to USI, definitions and compliance
regime are best viewed as proposed device regulations, not as
standards for achieving compatibility. Just as the U.S. broadcast
flag regulation adopted by the FCC was derived substantially from
the proposal produced by the Broadcast Protection Discussion Group
(the ATSC world's counterpart to DVB CPCM), the CPCM "standard"
is being written with an eye to its wholesale incorporation into
a statute book.
The nominal purpose of CPCM is to "enable
. . . business models", but this is an incomplete account.
The real purpose is to enable the business models that rightsholders
conceive of and endorse, even if it means disabling the business
models employed by device vendors to enrich their customers' viewing
experiences.
For example, the Virtuoso MC-500[35],
manufactured by Neuston, is a commercially available tool for
wirelessly retransmitting SCART signals over a short range. The
right to retransmit a programme within a household (rather than
stringing a wire) is included in the price paid by viewers for
their television subscriptions and/or the subsidy provided to
broadcasters in the form of free spectrum in which to broadcast.
CPCM USI would preclude this service by allowing
broadcasters to disable analogue outputs, or to control the number
of screens on which a programme may be viewed.
In other words, today viewers own the value
implicit in being able to move a TV signal around their homes.
Device vendors have created a business-model in helping viewers
realise this value.
CPCM will enable the "business model"
of taking away this value from Neuston's customers, rendering
Neuston's products and those like it useless, and then selling
this value back to customers as a value-added service on top of
any existing payment for television reception. The public as a
whole, including innovative new manufacturers, loses more value
than any manufacturer recoups under a CPCM scheme.
Summary
CPCM's main areas of specification
are Usage State Information (complex instructions for restricting
use after reception), definitional elements such as "Authorised
Domain" (a proxy for one household's worth of devices), and
compliance (rules that all manufacturers are required to follow
in implementing CPCM).
CPCM is intended to form the basis
of regulatory mandates in Europe, Australia and parts of Asia
and Latin America.
CPCM exists to "enable business
models" for rightsholders, even if doing so means destroying
the business models of some manufacturers.
CPCM AND COPYRIGHT
Copyright has never been an absolute and unlimited
property right. Rather, copyright is a limited monopoly granted
to creators in order to provide an incentive to engage in more
creative activity.
Every copyright system contains limitations,
exceptions and exemptions to the exclusive rights of authors and
performers. Software programmes are copyrightable as literary
works, but in most jurisdictions, software may be temporarily
copied in connection with legitimate acts of reverse engineering.
Some countries may grant authors exclusive rights to authorise
distribution of their works, but this is limited by the first
sale/exhaustion doctrine, which permits private citizens to lend
their music, books and movies to one another, and donate them
to schools or charities.
The copyright in a movie or TV programme is
also limited in many jurisdictions that recognize a right to make
private copies of these works.
In crafting a copyright policy, lawmakers take
great care to balance out the public interest with the need to
give incentives to authors and performers. This care is reflected
in the contours of the exclusive rights and the exceptions and
limitations on those rights that are reserved to the public, and
the latitude afforded to reverse engineering as a means of creating
interoperable products.
CPCM is often described as a system for protecting
copyright, but CPCM has been designed to protect exclusive rights
that are not in any copyright system. Structurally, it does not
even attempt to coincide with the concepts of any nation's copyright
law. Instead, it aims to maximize the range and scope of copyright
holders' and broadcasters' ability to impose restrictions unilaterally,
and to allow these restrictions to be as fine-grained as possible.
Broadly speaking CPCM takes rights away from the public and then
allows them to be sold back piecemeal.
For example, many national copyright laws contain
exemptions for members of the public who make copies of works
in order to add assistive information required by people with
disabilities. In the audiovisual realm, fans and public-spirited
individuals often add subtitles to films to help hearing-impaired
people, or narrative audio to help blind people. But within CPCM,
the ability to open recorded programmes in a tool used for this
purpose is limited by flags (such as the USI "Export Beyond
Trust" flag) which rightsholders can apply or withhold at
their discretion.
Likewise, the private performance and use of
copyrighted works (often including private copying) is generally
allowed without special permission from rightsholders. Copyright
has traditionally regulated only public uses of works. If you
want to bring a recorded TV programme upstairs to watch in the
bedroom, or to a friend's house to watch there, or if you want
to pause a movie before leaving for work and pick it up again
when you get home, that is no one's business but your own.
But CPCM is capable of restricting all of these
uses. Though a member of the public may have, under the laws of
her jurisdiction, every right to time-shift or space-shift or
use a pause button, there is nothing in the CPCM specification
that prevents a rightsholder from unilaterally imposing restrictions
on one or more of these activities.
In essence, CPCM allows rightsholders to manufacture
new copyrights for themselves and then impose them on the public
without regard to national copyright law.
Summary
Copyright has many limitations, exceptions
and exemptions that allow the public to make "unauthorised"
uses of copyrighted works.
CPCM does not respect copyright it
runs roughshod over the public's rights in the copyright bargain,
allowing rightsholders to misappropriate any exemption they desire.
Coupled with a regulatory mandate,
this amounts to permission to write private laws to underpin business-models,
at the public's expense.
CPCM AND COMPETITION
No DTV technology is CPCM-compliant today (it
would be impossible to build a CPCM device today, given the absence
of a finalised CPCM specification). For the foreseeable future,
CPCM will be present in a small minority of DTV devices.
The CPCM working groups recognise this and have
made plans for a system for granting permission to non-CPCM systems
to interoperate with a CPCM system.
In systems like this (eg, the licensing authorities
for Digital Transmission Licensing Administrator's Digital Transmission
Copy Protection (DTLA DTCP) and other DRM technologies), a managing
body of yet-to-be-determined composition will meet with technology
vendors who wish to interoperate with CPCM systems. These vendors
will make the case for their technology, demonstrating that it
has similar restrictions to CPCM and that it is licensed on similar
terms to CPCM.
This is how licensing systems for similar restrictions
systems worksuch as the DVD CSS system that is used to
ensure that features aren't introduced to DVD players that disrupt
the studios' business models or provide unwelcome competition
for incumbent technology manufacturers.
It is instructive to examine how these other
restriction systems work in the field. In general, a technology
company that wants to build such a system can do so (albeit sometimes
at high expense[36]).
However, the only companies that are given permission to add new
features to the restriction systems are those that are "in
the club" of companies that run the licensing for that technology.
For example, in 10 years of operation, the DVD-Copy
Control Association (which licenses new features for DVD players)
permitted the inclusion of no new interfaces in DVD players, save
those that were created by companies that are active in the DVD-CCA.
Indeed, one competitor of these companies, Kaleidescape, is currently
being sued for adding a restricted hard-drive jukebox capability
to DVD players. [37]
This concentration of manufacturers, erecting
barriers to entry for competitors, has grave implications for
competition, but it also impacts on the freedom of companies to
contract.
That is because when Alice gets permission to
use her technology in Bob's devices, Bob wants to know the terms
under which Alice will allow all other companies to connect to
her devices. Bob wants to be sure that a license to Alice doesn't
inadvertently confer a license to Charlie or David to receive
content from Bob's technology.
Which means that when Alice gets a license from
Bob, Alice's dealings with others become subject to pressure from
Bob. If Alice does a deal with Charlie, Bob may revoke Alice's
license to receive the content from Alice's devices, citing Charlie's
insecurity or general unfitness. Or Bob may exercise a veto over
Alice's device, demanding that the content he provides not be
output to Charlie's device.
This is the norm in DRM licensing today, but
today's DRM licensing bodies compete in a market where vendors
can choose not to do business with them. If CPCM becomes the subject
of a national legal mandate, then the CPCM licensing cartel will
dramatically undermine competition in the DTV marketplace.
Summary
CPCM's interoperability with other
technologies will be limited by contracts that ensure that no
disruptive entrants to the market are permitted.
These licensing regimes limit implementers'
freedom to contract with other technology vendors.
Historically, these licensing regimes
limit innovation in the industries to which they are applied.
CPCM AND CONSUMER
RIGHTS
The impact of CPCM on commercial interests will
indeed be grim, but far worse will be its impact on consumer rights.
Today, consumers can purchase devices knowing
what those devices do, and likewise can buy media with the understanding
that their media will not be orphaned by the forcible withdrawal
of players from the market.
If you buy a VHS VCR, you know that it plays
VHS cassettes. You know that your VHS recordings will play on
VCRs for so long as VCRs exist and so long as the tape holds out.
You can reasonably assume that no law will be passed requiring
manufacturers to cease offering VCRs in the market, so there will
be a supply of VCRs into the foreseeable future, even if mainstream
companies abandon them. If the VCR enjoys a renaissance (as has
the turntable with the growth of DJ culture), there will be no
legal impediment to manufacturers turning out VCRs to fill it.
But CPCM and systems like it are a very different
matter. Take the question of whether a CPCM system is suited to
some purposefor example, whether a CPCM-based recorder
can be used to create a collection of your favourite episodes
of your favourite television programme.
If the device in question were a VCR, the answer
would be a simple "yes".
But because CPCM devices are manufactured to
respond to any USI that is applied to a given programme, the answer
is "it depends". It may be that today you can record
your favourite programme and transfer it to DVDs for long-term
storage. But next week, the rightsholder for that programme can
change the deal and apply USI to it that prevents the act of recording
and/or the archiving to DVD. [38]
USI's complexity means that there is a vast
number of ways in which your USI-compliant devices and media may
fail you.
No onenot a sales-clerk in a shop or
a manufacturercan tell you, at the time of purchase, whether
your device will record or display the programmes you've bought
it for, nor whether it will go on doing so tomorrow.
Finally, there is the question of revocation.
As with comparable restriction systems in the field, CPCM contains
mechanisms for revoking the authority of devices and their outputs
to play back media. Media can ship with codes that allow it to
identify devices, peripherals and systems that it is not to be
played back on, because that device is known to have been compromised.
The DVD player/recorder you have plugged into
your receiver may not work on the next receiver you buy. The DVD
you bring home may not work on that player. Your recordings may
not play back the next device you buy. If someone, somewhere figures
out how to get your technology to do something that the rightsholder
group dislikes, they retain the power to retaliate by punishing
a limitless number of innocent bystanders.
Summary
It will be impossible to know, a
priori, whether a CPCM device will allow you to use it in the
way you intend on using it.
Even if a CPCM device does work "out
of the box", its functionality can be constrained at a later
date by disabling its features or activating USI in programming
that limits a desired feature
CPCM AND FREE/OPEN
SOURCE SOFTWARE
CPCM contains a "robustness requirement"
that demands that manufacturers design their technologies to resist
end-user modification. This is an extraordinary requirement for
free-to-air television receivers and the devices that connect
to them, where the general rule has been that manufacturers are
merely expected to make devices that work well, not devices that
stymie their owners' attempts to modify them.
This has a particularly harsh impact on Free
and Open Source Software (FOSS) development. FOSS is software
that is released under a license that allows end users to modify
it and redistribute it with their changes. Some FOSS licenses
require those who modify and distribute a programme to release
their modifications under the same terms.
Many large, successful companies employ FOSS
for part or all of their business. These include such DVB members
as Time Warner (Netscape), Sun Microsystems (Solaris) and Intel
(compilers, test suites, libraries), as well as companies such
as Red Hat (Red Hat Linux) and Google (Google Code).
FOSS delivers many benefits to manufacturers,
including lower development and quality-assurance costs, more
robust code, and the positive marketing effect of selling technologies
that users are free to modify if they have the will and the ability.
The success of the GNU/Linux operating system
and the Mozilla/Firefox browsers has demonstrated the ability
of FOSS to act as a countervailing force to check monopolistic
practices in the market (for example, the availability of the
GNU/Linux operating system has led to lower cost licenses for
Microsoft's operating systems in developing nations, and competitive
pressure from the Mozilla/Firefox browser has resulted in a higher
level of standards-compliance and functionality in Microsoft's
Internet Explorer).
Most important is the ability of FOSS to foster
innovation and the creation of knowledge and expertise by inviting
all interested parties to collaborate with one another, by improving
on each others' works, by modifying them, and by publishing their
outcomes.
This is the programmer's equivalent of the scientific
method, the centuries-old practice of publishing your work for
peer review and to add it to the commonly held pool of knowledge.
Scientists, engineers and educators rely on
FOSS as a tool for furthering the pursuit of knowledge. Imposing
CPCM on digital television shuts them out of this promising area
of inquiry.
Summary
CPCM's robustness requirement will
make it impossible to implement CPCM in free and open source software
(FOSS) and hence FOSS programmes will necessarily be precluded
from the market if CPCM is mandated into national law.
The right of programmers to publish
their work through FOSS regimes is often equivalent to other forms
of scientific publishing and is often protected under free speech
laws and traditions.
The CPCM robustness regime will therefore
stifle free and open source software and the scientific inquiry
that relies upon it.
THE BROADCAST
FLAG, THE
BROADCASTERS' TREATY
AND CPCM
CPCM is part of a global strategy on the part
of the Hollywood companies to create a new regulatory regime that
allows them to use their limited copyright monopoly over who can
copy their movies to obtain an unlimited monopoly over who can
design new interoperable technologies that challenge their business
models.
At the DVB World conference in March 2005, Spencer
Stephens, speaking on behalf of the North American Broadcasters'
Association, offered a presentation on this subject. Stephens
is an executive with TimeWarner, and represents that company within
DVB, where he sits on the steering board.
This presentation laid out a roadmap for stitching
the US Broadcast Flag and the DVB initiative into a global system
for restricting recording and distribution. The presentation went
on to call for the incorporation of obligations to mandate redistribution
controls into its proposed new World Intellectual Property Organisation
Treaty for the Protection of the Rights of Broadcasting, Cablecasting
and Webcasting Organizations.
With the US Broadcast Flag in tatters, the Hollywood
companies are engaged in the classic tactic of securing laws abroad
that serve as justification for legislating an equivalent American
regime (and vice versa). This transatlantic copyright ping-pong
has already been used successfully by the studios to secure extensions
of the term of copyright on both continents[39],
each in the name of harmonising with the other, and to extend
the scope of copyright well beyond its historical contours.
While DVB is often sold as a made-in-Europe
solution, Stephens' presentation, coupled with the material emerging
from CPCM shows that DVB's CPCM activity has been subverted to
achieve American entertainment companies' goals at the expense
of worldwide self-determination.
Summary
CPCM is the latest salvo in a global
campaign to restrict consumer rights that encompasses US initiatives
like the Broadcast Flag and WIPO (UN) initiatives like the Broadcasters'
Treaty.
CPCM encompasses many failed US regulatory
initiatives and the move to encase it in international treaty
obligations will likely be used as leverage to get these initiatives
reintroduced in the USA.
CPCM compromises national self-determination
by allowing US culture-exporting companies to dictate public policy.

For comparison, in the US, the Recording Industry Association

The DVB negotiations proceed in secret, and participants in the
negotiation sign a "memorandum of understanding" in
which they undertake to give each sub-group's chair the exclusive

This is not a purely hypothetical example: Americans who bought
Microsoft Media Center PCs to record The Sopranos last year got
a nasty shock when, halfway through the season, HBO activated
a use-control flag analogous to USI that made it impossible to
save their recordings to DVD. People who bought their Media Centers
to library the Sopranos purchased a device fit for this purpose
in September, but useless come December, because there was a hidden
restriction flt on ag waiting to be triggered by the cablecaster.
Likewise Americans who received PVRs from Comcast and used them
to record Six Feet Under discovered that their libraries of the
show were remotely deleted just prior to the DVD release-the rightsholders
were able to reach into the public's sitting rooms and take away
the recordings they'd made. Back

http://en.wikipedia.org/wiki/Directive_on_harmonising_the_term_of_copyright_protection
"Because [the Directive on harmonising the term of copyright
protection's] extended term (longer than that required by the
Berne Convention) was made available within the EU to non-EU copyright
owners on the basis of reciprocity, the directive was one of the
main arguments in favour of the (now highly controversial) US
Sonny Bono Copyright Term Extension Act." Back
