I. About EFF
The EFF is a member-supported nonprofit organization devoted to
protecting civil liberties and free expression in technology, law, policy and
standards. With over 7,000 dues-paying members and over 30,000
mailing-list subscribers, EFF leads the global and national effort to ensure
that fundamental liberties are respected in the digital environment.
EFF has been involved with the broadcast flag issue since
November 2001. We participated in all the meetings of the Broadcast

II. Introduction
Advocates of a broadcast flag mandate--primarily motion picture
studios and the technology firms who stand to gain an advantage as a
result of the mandate--present the flag as a technical solution to a
perceived problem of "Internet piracy" the redistribution of free, over-the-
air television programming on the Internet without authorization.
In their view, unauthorized Internet redistribution will explode as a
consequence of the DTV transition, and fear of this hypothetical explosion
is purportedly chilling motion picture companies from licensing works for
broadcast on DTV. They contend that their reluctance and the resulting
shortage of "high-quality content" available through terrestrial DTV
broadcast is retarding the transition to DTV, and so are calling upon
government to back a broadcast flag mandate to set their minds at ease.
Once they are comfortable with the "safety" of DTV, so goes the
argument, they may make more "high-quality content" available, and
thereby spur consumer adoption of DTV.
These contentions and the conclusions that flow from them are all
highly suspect. First, whether or not "Internet piracy" is a problem today,
the terrestrial broadcast of DTV has nothing to do with that "problem."
Second, even in the absence of a broadcast flag mandate, there is plenty of
high-quality content (even high-quality films from the vaults of the major
motion picture studios) on free, over-the-air DTV channels. Today, fully
half of the most popular prime-time television programs are being
broadcast via DTV.
And more programming is on the way.
Furthermore, even if DTV posed a new and serious threat of
unauthorized Internet redistribution, the broadcast flag would do nothing
to eliminate it. Infringers will go on using the same tools to send files to
the same people, unimpeded by the broadcast flag.
In short, a broadcast flag mandate is an ineffective solution to a
non-existent problem. At the same time, any broadcast flag mandate will
impose genuine and substantial costs on consumers and innovators. It
would raise the cost of DTV devices while reducing the value that they
represent to consumers. It would stifle innovation in DTV and general-
purpose technologies. It would abridge the First Amendment freedoms of
software authors. All of this, in the end, will impede, rather than
encourage, the transition to DTV.

Half of the top 20 U.S. prime-time television shows (via, reporting share as of December 1,
2002) are on the air today via terrestrial DTV broadcasts.

DTV has nothing to do with "Internet piracy;"
and even if it did, a broadcast flag mandate would be
completely ineffective at addressing the problem;
while posing a substantial threat to consumers, innovation
and the DTV transition itself.
III. A Broadcast Flag Mandate Responds to a Nonexistent Problem
Advocates of a broadcast flag mandate justify their position with a
simple story that usually goes something like this: the problem of rampant
unauthorized Internet redistribution has made copyright holders reluctant
to release content for terrestrial DTV broadcast, which has resulted in a
paucity of compelling content that would otherwise drive consumer
adoption of DTV.
In other words, the broadcast flag mandate is meant to respond to
two problems: (1) unauthorized Internet redistribution of DTV content and
(2) the shortage of compelling DTV content that results from the fear of it.
A. Digital Television Has Nothing To Do With "Internet
Unauthorized Internet redistribution is a problem
that simply has
no nexus with DTV today, and is not likely to have any appreciable nexus
with it in the foreseeable future. Accordingly, any broadcast flag mandate
will have no impact on the problem, so long as alternate channels for
infringers (e.g., analog broadcasts, cable television, DVDs, and
camcorders) exist.
The vast majority of infringing content shared on the Internet today
is captured from analog NTSC broadcasts or cable transmissions,
extracted from DVDs, or recorded by camcorders. Any broadcast flag
mandate, of course, will have no impact on these other sources, and thus
no impact on the stock of unauthorized content.
So the proper question becomes: do "unprotected" terrestrial DTV
broadcasts represent any unique or additional risk of unauthorized Internet
redistribution over and above the status quo? The answer is no.

This assumes that unauthorized Internet redistribution is a "problem" at all. While the
practice certainly qualifies as a "problem" from a copyright law perspective, some have
suggested that it may actually constitute a new business opportunity for the copyright
industries. See, e.g., KPMG, The Digital Challenge: Are You Prepared (released
September 25, 2002) (available at

1. High-definition DTV programming cannot practically be
redistributed through consumer-grade broadband channels.
Some advocates of a broadcast flag mandate contend that the
improved quality of DTV broadcasts (referring to perfect, high-resolution,
digital copies and "instant" or "immediate" retransmission) will prove an
irresistible draw for infringers intent on Internet redistribution. This
contention, however, cannot survive scrutiny. The vast majority of the
video content being distributed without authorization over the Internet
today is at a quality well below that of standard-definition ("SD") NTSC
broadcasts, much less the HD quality made possible by DTV. The reason
is that high-quality video files are simply too large to redistribute over the
Internet using consumer-grade Internet connections. The capabilities of
consumer broadband, moreover, are not likely to change this reality in the
foreseeable future.
Recordings of high-definition broadcasts are huge. ATSC
provides up to 19.4 megabits/sec of data capacity, and 1080i broadcasts
use nearly all of this capacity. This means that HDTV video data enters
the home at over ten times the speed of a "T1" line.
A two-hour movie at
this rate occupies nearly 140 gigabits (about 17.5 gigabytes). Under
assumptions that grant infringers hypothetical ideal conditions, an
infringer who dedicated her entire broadband Internet connection to
sharing movies (to the exclusion of all other applications) would require at
least 40 hours to download a single two-hour movie in HD format.
40-hour figure is a best case scenario, presuming that the downloader
finds a source able to offer sustained downloading rates equal to the full
capacity of her broadband connection, turns over the entire use of her
broadband connection to the transferring of one file, and does not
experience a failure of her Internet connection, interruption from the
source, or a software malfunction over 40 hours of continuous use.
The broadband capacity of the typical American consumer,
moreover, is unlikely to increase in the near-term to overcome the barrier
of HD file sizes. First, broadband deployment to the American home has
been slow, with fewer than 11% of American households subscribing to

A T1 line is a very high speed Internet connection, with a data rate of 1.544
megabits/sec. T1 connections today are normally used for business Internet access, and
service providers generally do not attempt to offer them to consumers. (T1 service in a
major urban market such as San Francisco typically costs $500-$1,000 per month,
making it an unrealistic option for consumer Internet access.) While a few markets offer
consumer broadband services with theoretical peak download rates near T1 speeds,
upload rates (which are relevant to the ability to share a file with another Internet user)
are wildly asymmetrical, running at a fraction of the download speed.
If a user sustained a 1 megabit/sec download rate for 40 hours with extremely low
overhead, she could download a single copy of such a movie.

broadband service.
More importantly, however, the infrastructure
realities of the "last mile" suggest that even if penetration increases,
bandwidth is unlikely to grow substantially.
In fact, recent trends suggest
that consumers may see less bandwidth before they see more, as major
ISPs are considering "metered" pricing plans to control their bandwidth
In other words, the average American household will be lucky to
get a broadband connection equivalent to today's DSL and cable modems,
and is not likely to see higher-bandwidth connections in the near term.
2. Copyright infringers have, and will continue to have, ample
adequate alternative sources for video content.
Recordings of high-definition broadcasts are an unattractive target
for Internet infringers, who have proven unable to take advantage of what
is already available to them today. High-quality recordings of standard-
definition programming, which make for file sizes far smaller than
recordings of high-definition programming, are readily available to
prospective infringers. Unencrypted standard-definition digital recordings
can be obtained readily from NTSC broadcast, from analog cable service,
or from DVD discs.
Despite the ease with which digital SD recordings
can be obtained, they are not generally shared on the Internet at even their
native 480i quality.
Instead, infringers reduce the quality to well below

Commerce, September 23, 2002, at 5 (available at

#105, (July 2002)
NTSC transmissions via terrestrial broadcast or cable service can be recorded readily
with a TV tuner card in an ordinary PC; such cards are now sold starting at around $40.
The recording thus obtained suffers a single one-time generational quality loss in
recording; modern low-noise analog to digital conversion technology means that this loss
of quality is imperceptible to a typical viewer. Moreover, "ripping" (transcoding for
redistribution, archiving or format-shifting) a DVD requires minimal technical
knowledge. Transcoding software and dedicated transcoding devices are readily available
from various domestic and foreign suppliers. Even if a small fraction of the public
chooses to use these technologies, their efforts result in downloadable versions of
commercially released DVDs that can be redistributed without any special technical
We do not believe that the quality of infringing copies of works shared on the Internet
has been studied in detail with a carefully controlled methodology. We observe that
public claims about the nature and impact of Internet copyright infringement are lacking
in empirical evidence and rigorous technical analysis, and we welcome continued
scientific inquiry in this area. Many relevant questions appear to be purely quantitative.
It is clear that rigorous research is possible on the actual uses and capabilities of file-
sharing networks to transfer extremely large files; see, e.g., Subhabrata Sen and Jia
Wang, "Analyzing Peer-to-Peer Traffic Across Large Networks," Internet Measurement

that of 480i, using both "downrezzing" (reducing the resolution of the
video source to produce a smaller, lower-quality picture) and "lossy"
compression (where the video and audio quality are substantially degraded
in the service of reducing the files to a more transmissible size) to sacrifice
picture quality in order to reduce download times. This practice
demonstrates that infringers have not generally found it practical to share
widely even 480i or 480p content conveniently available to them--let
alone the 720p or 1080i content brought to them by DTV broadcasts. So
long as the content being broadcast on DTV remains widely available in
these lower-resolution formats, DTV represents no incremental increase in
the Internet redistribution threat.
B. High-Quality Content is Abundant on DTV Today
The second "problem" that the broadcast flag mandate is intended
to address--the shortage of compelling DTV content occasioned by fears
regarding "Internet piracy"--also turns out to be chimerical. If the DTV
transition is behind schedule, it is not because of a lack of high-quality
content. A large and growing body of works from the major studios,
networks and their affiliates is available to from terrestrial DTV
broadcasts today.
Already, fully half of the 20 most popular primetime
programs are broadcast over terrestrial DTV.
In addition, new
producers, such as HDNet, are working to fill any vacuum left
unaddressed by the incumbent content producers. All of this is occurring
in the absence of a broadcast flag mandate.
In fact, not only are the major networks making an increasing
quantity of their content available on DTV broadcasts
, but some
newcomers actively oppose a broadcast flag mandate. For example, Mark

Workshop 2002 (November 6, 2002) (available at (characterizing statistically various
features of peer-to-peer file-sharing traffic on actual networks based on statistics from
major ISPs' routers). Additional evidence of this sort may be useful to the Commission
and to a broader discussion of the nature of Internet file sharing.
"With the fall TV season gearing up, the National Association of Broadcasters (NAB)
today announced that High-Definition Television programming is at a record high, with
2,000 hours of prime-time shows, sporting events and movies scheduled to be broadcast
in HDTV in the 2002-2003 television season. `Broadcasters have taken the lead
in the Digital Television revolution by giving viewers thousands of hours of premium
programming in HDTV format," said Eddie Fritts, President and CEO of NAB."

Cuban, President of HDNet, the only national all-HD television network,
opposes such a mandate, considering it unnecessary and even
counterproductive to DTV adoption.
HDNet is aggressively licensing its
HD content for terrestrial broadcast in the absence of a broadcast flag
In light of the above, it does not appear that compelling content is
being held back from terrestrial DTV broadcast. What's more, even if it
were, a broadcast flag mandate is no answer to the problem: no rights-
holders have made any commitments to make additional content available,
even were a broadcast flag mandate to be enacted.
DTV files are too large to be practically shared over the
Internet infringers have a ready supply of equally attractive
programming from other sources;
Internet infringers cannot widely share even standard-
definition video;
High-quality DTV programming is available today, with
availability increasing steadily;
A broadcast flag mandate will not guarantee that additional
programming will be made available.
IV. If There Were a Problem, the Broadcast Flag Wouldn't Solve It
Even assuming (as advocates of a broadcast flag mandate do) that
unprotected terrestrial DTV broadcasts are vulnerable to widespread
unauthorized Internet distribution, a broadcast flag mandate would be
hopelessly ineffective at addressing the problem.
The broadcast flag, by its nature, is an absurdly weak form of
security technology.
Accordingly, any effort to mandate that DTV
receivers respond to the broadcast flag will be undermined by at least three
simple methods available to any infringers interested in Internet
redistribution: (1) noncompliant receivers, both hardware and software,
can always be easily obtained or built because the relevant technology
standards are publicly documented and widely understood; (2)
noncompliant legacy devices will continue to receive and output DTV

See, e.g., "Cuban Bids Broadcasters Ignore Hollywood on Rights Management,"
Warren's Washington Internet Daily, April 9, 2002 (reporting on Cuban speech opposing
copy control mandates, delivered at NAB conference).
In fact, it has been our experience that some engineers burst into spontaneous laughter
upon first learning of the broadcast flag mandate proposal. "You must be joking," is
another common response from technical audiences.

signals without responding to the broadcast flag; and (3) analog outputs on
compliant devices will be subject to "redigitizing" (sometimes referred to
as the "analog hole").
A. The Broadcast Flag Is a Weak Security Measure
In order to evaluate the efficacy of the broadcast flag as a measure
to reduce unauthorized Internet redistribution, it is helpful to understand
the nature of the threat. As experts have noted, all it takes is one "leak" in
a content security system to facilitate global unauthorized Internet
All it takes is a single person to capture content in
unprotected digital form--once posted to file-sharing networks, the
content will quickly propagate. As a result, even the most secure copyright
management systems are at risk. (Comparatively speaking, the large size
of HD recordings relative to the capacity of consumer broadband
connections is a far more effective deterrent to file-sharing than the
broadcast flag.)
As a matter of technology, the broadcast flag (also known as the
rc_descriptor) is a remarkably weak security measure. Indeed, some
technologists are reluctant to call it a security measure at all. The
broadcast flag is merely a label that advises receiving equipment without
controlling its operation. The broadcast flag by itself has no power to
control or affect the operation of any device, or to prevent non-compliant
devices from continuing to operate and to process marked signals.
Security experts agree that a flag or label-based approach is technically
weak in the presence of "untrusted systems;" it can only be effective when
all systems co-operate to give it effect. A broadcast flag mandate,
however, cannot rid the world of untrusted systems. Even were the FCC to
impose a mandate tomorrow, every existing receiver would constitute an
untrusted system, as it would continue to receive and output DTV
broadcasts while ignoring the broadcast flag.
Determined infringers' access to DTV programming would be
unimpeded by a broadcast flag mandate. DTV programming would
continue to be broadcast unencrypted to anyone who desired to receive it,
using freely published standards that can be, and were meant to be,
implemented by any technologist.
Existing equipment, and any newly

In the words of a recent Microsoft research paper analyzing the problem of
unauthorized Internet redistribution, "If there are subverted hosts, then content will leak
into the darknet [uncontrolled distribution channels]. If the darknet is efficient, then
content will be rapidly propagated to all interested peers." See Peter Biddle, Paul
England, Marcus Peinado, and Bryan Willman, "The Darknet and the Future of Content
Distribution," presented at the 2002 ACM Workshop on Digital Rights Management,
November 18, 2002 (available at

to receive DTV broadcasts. Outputs from these devices would continue to
be indifferent to the presence or absence of the broadcast flag.
devices capable of ATSC demodulation have already been sold and many
more would be sold before any regulation could be effective. Finally, even
compliant receivers would represent a vulnerability, as their analog
outputs (in the absence of additional technology mandates addressing
analog outputs) could easily be redigitized using inexpensive commodity
PC peripherals. These analog-to-digital ("A/D") conversion devices,
mature technology that is readily available in the market today, would be
unaffected by a broadcast flag mandate and would constitute a "leak" that
could be used to facilitate unfettered Internet redistribution.

Television Standard, Revision B (August 7, 2001), Annex D, "RF/Transmission System
Characteristics." (SMPTE and NAB published earlier versions of this document, and the
Commission, on adopting an earlier version as the U.S. digital television transmission
standard, made that version available for public inspection. See In the Matter of
Advanced Television Systems and Their Impact Upon the Existing Television Broadcast
Service (MM Docket No. 87-268), Fourth Report and Order, December 24, 1996,
Appendix A, codified at 47 C.F.R. 73.682(d). The current authoritative version is
available directly from ATSC via the World Wide Web at The same standard notes
the goal of providing sufficient technical information for any party to create an
interoperable implementation:
The normative clauses of the Standard do not specify the design of a receiver.
Instead, they specify the transmitted bit stream and RF signal with a
thoroughness sufficient to permit the design of a receiver.
Id., Annex E, "Receiver Characteristics," at p. 68 (emphasis added). The technical
details of ATSC broadcast are also described by other standards documents, discussed in
textbooks, and taught in schools to electrical engineers. The ATSC standards were
deliberately intended to facilitate many independent implementations. The Commission
considered it essential that, like the NTSC standards, the details of the ATSC standards,
with which broadcasters are required to comply, should be available to all. Of course,
there is no suggestion by advocates of a mandate that this technical information would be
withdrawn from circulation or that technologists of the future would somehow remain
ignorant of the means of receiving ATSC broadcasts.
As the Commission predicted in 1996,
[when ATSC was altered or extended, t]he resultant conditions would be
reminiscent of the introduction of color or stereo sound to the NTSC system.
Earlier equipment continued to work unimpaired even as newer equipment
provided additional or improved features.
In the Matter of Advanced Television Systems and Their Impact Upon the Existing
Television Broadcast Service (MM Docket No. 87-268), Fourth Report and Order,
December 24, 1996, at para. 41. Earlier equipment would, in this sense, likewise "work
unimpaired" if newer equipment instead provided fewer or more limited features. As a
technical matter, the introduction of the rc_descriptor into the PSIP standard has indeed
had no effect on devices that do not assign a meaning to this descriptor.

B. It Will Always be Easy to Build or Acquire Noncompliant
Since the ATSC specifications are published openly, no reasonably
sophisticated engineer is lacking the necessary technical details to
implement this operation from scratch. The digital-signal processing
operations necessary to convert a spectrum sample into an MPEG-2
stream are simply a series of mathematical calculations, which can be
specified precisely, and can be implemented on any general-purpose
computer or calculating system. Indeed, every PC with adequate
processor power is susceptible to being programmed to perform this

ATSC demodulation can be performed entirely in software on a
general-purpose computer supplied with a suitable raw spectrum sample.
A practical software ATSC demodulator is currently under development
by the GNU Radio project, a project of the Free Software Foundation.

This project underscores the technical straightforwardness of
implementing VSB demodulators, since two engineers with no corporate
support and no prior television engineering experience produced a
working prototype in under a year.

Since the broadcast flag is only a flag and does not affect the
modulation, quality, or format of the signal at all, these "noncompliant"
systems will not necessarily respond to the broadcast flag. The means of
demodulating ATSC to MPEG-2 is widely known and widely available--
to consumers, to off-shore manufacturers, and, most importantly, to
would-be infringers. Implementing a broadcast flag mandate in this
context would create an effectively impossible enforcement challenge.
C. Legacy Devices Will Ignore the Broadcast Flag
ATSC tuner cards designed to be inserted into general-purpose
PCs were independently developed in a relatively short time by several
manufacturers, and are being sold freely today. ATSC demodulator chips,
already readily available in the market, can be used to fabricate DTV tuner

The speed (but not the basic feasibility) of software demodulation depends on the
characteristics of the computer hardware on which the demodulation is performed.

D. The Analog Hole Renders the Broadcast Flag Irrelevant
Broadcast flag proponents, in the course of other legislative
advocacy, have admitted that the broadcast flag measure cannot be
effective by itself because of the so-called "analog hole." MPAA
explained in a submission to Congress that measures relying on encryption
might be of limited effectiveness since
[d]igital devices can capture and digitize unprotected
analog signals (including formerly protected digital signals
that are stripped of their protection as they pass through
analog outputs) with complete disregard for current analog
copy protection mechanisms, thus enabling a major source
of unauthorized duplication and/or redistribution.

In addition, at a recent roundtable hosted by the Associated Press, Warner
Brothers Chief Technical Officer Chris Cookson admitted that any
broadcast flag mandate that failed to address analog outputs would be
entirely ineffective at reducing Internet redistribution of content.
Analog-to-digital ("A/D") conversion, sometimes referred to by
entertainment industries as "the analog hole" or "re-digitization," is a
routine and straightforward process. If you connect a DVD player's analog
outputs to a computer's video capture card, the computer will create a
digital recording from the DVD's output, performing an A/D conversion.
A/D conversion capabilities for audio and video are readily available to
consumers at relatively low cost.
The costs of video capture capabilities,
moreover, are falling rapidly.
Where DTV is concerned, performing A/D conversion can yield a
near-perfect digital copy, subject to an imperceptible loss of quality,
especially if the high-quality "component" video outputs offered by many
HD-capable sets and tuners are used. Virtually every DTV device sold to
date includes an unprotected, high-quality analog output, as all but the
most recent generation of DTV displays rely on analog inputs. No publicly

solution to this gaping vulnerability.

Some supporters of the broadcast flag mandate have advocated

Such proposals are beyond the scope of this rule-making,
potentially reach a dizzying array of commonly-used technologies, and are
extraordinarily controversial. Moreover, efforts to impose mandates on
analog outputs raise the specter of making all legacy HD sets and displays
obsolete (as such devices typically have only analog inputs), potentially
leaving millions of American consumers stranded with display devices
that can no longer fully interoperate with new DTV receivers and
If there were a problem with DTV infringement on the
Internet, a broadcast flag mandate would not address it;
Building noncompliant receivers is easy, making any
broadcast flag mandate effectively unenforceable;

broadcasts without regard for the broadcast flag;
The "analog hole" permits the re-digitization of any DTV
signal notwithstanding the broadcast flag, without a
perceptible loss of quality.

[...] This means the digital signal is immediately transformed into an analog signal in

One way to `plug the hole' could be through a `watermark detector.' The `watermark' is
an ingenious design, which commands the signal converter in the TV set to respond to the

V. The Broadcast Flag Harms Consumer Interests and Slows the DTV
Because it would be an ineffective solution to a nonexistent
problem, the benefits that would flow from a broadcast flag mandate are
few. At the same time, the costs are high. A broadcast flag mandate would
necessarily threaten fair use and legitimate consumer expectations, as well
as interoperability, innovation, and constitutionally protected speech,
thereby impeding, rather than assisting, the DTV transition.
A. A Threat to Fair Use and Legitimate Consumer
No use-control scheme can avoid placing some burden on
legitimate activities. A broadcast flag mandate is no exception. Collateral
damage to legitimate, noninfringing activities is inevitable because content
protection technologies cannot reliably determine whether a use is
infringing or non-infringing, and cannot predict future uses that might be
deemed fair.
U.S. copyright law has always recognized that the rights of
copyright holders are not absolute and are subject to various limitations
where the public interest would otherwise be adversely impacted. Since
1841, courts have recognized that the public has the right to make "fair
use" of copyrighted works, even where the copyright holder objects to the
use in question. Fair use is an integral part of the copyright law. Indeed,
the Supreme Court has held that the doctrine of fair use is required in
order to promote the exchange and free flow of ideas and information that
underpins the right of free speech, and that leads to creative innovation.

But by its nature, fair use requires a fact-specific and case-by-case
analysis and is not reducible to a set of technical rules. A DTV receiver
can't examine the intent of its user, or the market impact of the user's
actions, each of which might be highly significant to determining whether
the actions would be deemed fair. Congress has left the decision about
whether a particular use is fair to courts, to decide after weighing various
factors and the underlying purposes of the copyright law.

Amendment Skein," 54 Stanford Law Rev. 1 (2001) (examining historical relationship
between copyright and free expression, noting that courts have considered fair use and
related doctrines necessary and sufficient to protect the public's first amendment rights,
and arguing that these doctrines may now be insufficient to this purpose) (available at

broadcast flag mandate would condition the ability to exercise some use
on whether that capability is permitted within the limits of the mandate's
regulation of input, output, and robustness requirements. Accordingly,
such a mandate necessarily sacrifices noninfringing uses by failing to
accommodate the fact-based analysis intended by Congress.
Collateral damage is also inevitable because the broadcast flag
mandate cannot hope to accurately predict future noninfringing uses. If,
for example, the federal government had in 1972 imposed a mandate on
devices capable of recording analog television, and had judiciously
followed the borders of fair use precedents of the day, such a mandate
would almost certainly have prohibited the range of functionality
represented by the first consumer VCR, introduced by Sony four years
It is one of the great strengths of the fair use doctrine that it is
capable of evolution. This advantage arises from the fact that copyright
law allows technology vendors to innovate first, and test the innovation in
court later. It is one of the great weaknesses of technology regulations like
the broadcast flag mandate that they require innovators to ask for
permission before they may innovate, often from incumbent industrial
giants with a vested interest in stopping disruptive innovation.
Broadcast flag proponents minimize the costs of a technology
mandate and emphasize that certain non-infringing uses will remain
possible. By exaggerating the scope of these "permitted" uses, some
proponents have even suggested that legitimate consumer expectations
would not affected at all by a broadcast flag mandate. The basis for this
peculiar claim seems to be that simulacra of certain existing devices
(especially the analog VCR) can be implemented by means of these
technologies. On this view, so long as the remote control has the same
buttons, consumers have lost nothing. Of course, this fails to recognize
that consumers are losing future features (including both buttons on a
future remote that have not been invented yet, as well as existing buttons
that have yet to be tested in court
But a broadcast flag mandate will deprive consumers of more than
merely future innovations. A broadcast flag mandate would force existing

The question of whether automatic commercial skipping features fall within the scope
of consumers' fair use rights is currently being tested in a court case involving
ReplayTV. See Paramount Pictures Corp. v. ReplayTV, Inc. No. CV-01-09358 FMC.
Similarly, court cases may soon address the question of whether consumers have the right
to edit movies they have legitimately purchased in order to remove profanity and nudity.

Reporter, Oct. 30, 2002 (available at

products off the shelves without replacing them with anything comparable.
It would eliminate legitimate features and functionality that consumers are
enjoying today.
Examples of activities that are possible today but could be banned
under a broadcast flag mandate similar to the one proposed in the BPDG
Final Report include:
Recording DTV broadcasts to standard universally-
playable removable media formats, such as recordable
Sending a short excerpt of a DTV broadcast to a relative
via e-mail.
Recording or transferring a DTV broadcast to a laptop
computer's hard drive, in order to watch it later (for
example, on an airplane).
Transferring a recording of a broadcast over any TCP/IP
network, such as a home Ethernet or wireless Ethernet
("WiFi") network, in order to move a recording between
playback devices.
Incorporating an excerpt of a broadcast program into an
academic report, a documentary or work of scholarship, or
into a home movie.
This is not a question of whether these activities could be enabled
in the future: they, and other lawful and useful capabilities, are available
and practical for DTV viewers right now with current technology, using
commercially available products. Consumers are already benefiting today
from the ability to make these and other uses of DTV, but the requisite
technology would be forbidden to them under a broadcast flag mandate.
Generally speaking, consumers anticipate that they should be able
to do with DTV what they have done with analog television.
But the
real promise of DTV is much greater. It can, and should, supply the
flexibility to allow the development of new and previously unanticipated
uses. That flexibility--and not solely picture quality--promises to
provides consumers with unique value from making the DTV transition.
B. A Threat to Interoperability
The collateral damage that would result from a broadcast flag
mandate extends beyond frustrating consumers' legitimate expectations.

Before making the substantial investment involved in the DTV transition, consumers
have a right to expect that they will have at least the same capabilities with DTV that
they have with traditional analog television. For example, most PVR owners today will
likely resist DTV until equally functional PVR devices are available for DTV content.

By banning the use of "unapproved" outputs and recording methods and
by requiring "robustness" (i.e., tamper-resistance) in all compliant devices,
a broadcast flag mandate could create a welter of confusing, mutually
incompatible systems that will raise the cost of DTV devices while
reducing their value.
There is presently substantial uncertainty about compatibility and
interoperability on the part of consumers who are considering buying HD-
capable equipment. Prospective DTV adopters all across America are
asking questions like these:
If I buy a TV right now that doesn't have a DVI input and
this becomes the standard, is the TV useless for HD? Is it
possible to make an adapter that will convert the DVI
signal to component? Furthermore, if DVI is the standard,
will all of the receivers that are used as switchers need to
incorporate this as well?

Consumers are reluctant to purchase equipment because they don't
know whether the equipment will continue to function in the future--and
whether it will continue to interoperate with other equipment they might
want to purchase later on. They want to know whether a suitable adapter
will be available to guarantee interoperability. This consumer reluctance
will be exacerbated by a broadcast flag mandate, as it will take vendors at
least 18-24 months to design and bring compliant devices to market. In the
meantime, consumer uncertainty may take a substantial toll on the DTV
The consumer question above emphasizes the indirect costs that
would be imposed on consumers by a broadcast flag mandate. As a
technical matter, there is no reason why an adapter to convert a signal
between any arbitrary pair of interfaces might not exist. Where there is
demand for such an adapter, there are many vendors ready to manufacture
it. Unfortunately, the prospect of a broadcast flag mandate reduces the
chance of this reasonable consumer expectation being met in the
marketplace. Many useful adapters capable of preserving compatibility
would be out of bounds. Further, a mandate risks indirectly making
various products obsolete because of the narrowed pool of other products
with which they are permitted to interoperate. The additional restrictions
that would be imposed on recording create further risks that devices
bought today could be substantially less useful in the future.
One consumer electronics magazine gives us an example of this
sort of risk: "Unfortunately," it says, "D-Theater tapes won't play on non-

Richard Straus, letter to the editor, Home Theater, December 2002, p. 18.

D-Theater-certified D-VHS players."
Ordinary D-VHS tapes will play
on all D-VHS players; consumers are currently permitted to make, and
able to make, ordinary D-VHS recordings of terrestrial broadcast, and
therefore to be sure of achieving the greatest possible compatibility. The
BPDG Final Report contemplates eliminating consumers' present ability
to record flagged programming onto ordinary D-VHS tapes, requiring
instead that consumer recordings be less-compatible encrypted D-Theater

Consumers ought to be assured that, regardless of which players
they possess, interoperable recorders will continue to be available. They
ought to be assured that, regardless of the display devices they possess,
interoperable video sources will continue to be available. They ought to
be assured that, in general, adapters to convert one interface to another
will continue to be available. Not only can these assurances not be given
while a mandate looms, but these assurances may well be false under a
C. A Threat to Innovation
Encouraging innovation in digital television technology has been
part of U.S. DTV policy since its inception. In adopting the ATSC
standard, the Commission specifically noted its desire "to encourage
further innovation by those who have devised the ATSC DTV Standard as
well as new entrants."
A broadcast flag mandate, however, would retard,
rather than encourage, DTV innovation.
The value of any new technology is in large part derived from
unanticipated, innovative uses, uses that spring up as the widest possible
variety of technologists and end-users tinker, modify, and experiment to
discover remarkable ways of extracting new value unimagined even by the
technology's inventors. The explosive growth of technologies such as the
Internet, the cellular phone and the automobile is characterized by a
Cambrian explosion of innovation in each case. From the drive-in theater

BPDG Final Report, Tab C-2 (dated June 3, 2002), at 7 (proposing obligation for D-
VHS recordings to include copy controls). No such restriction exists today, and D-VHS
equipment is currently able to make maximally compatible recordings of ATSC
broadcasts. See, e.g., "[A]ll D-VHS decks [as of 2001] also allow you to record (via
MPEG-2 encoding) high definition broadcasts off the air[.]" "D-VHS--A First Look At
a New Format," The Digital Bits, January 31, 2001 (available at

to telephone dating to Internet-based auctions, innovation has been a
principal driver of consumer adoption of a new technology.
Innovation flourishes in the absence of stricture. Hot-rodders and
overclockers both rely on open hardware to tweak their equipment for
maximum performance, and even an average driver would balk at the
notion of purchasing an automobile whose hood was welded shut. A
broadcast flag mandate, particularly if it includes tamper-resistance
requirements, effectively welds shut the hood of every DTV device. It
insists that only authorized parties may peek at the works of any given
DTV device, and requires that interoperability be subject to the prior
consent of vendors who may have reason to discriminate against new
market entrants. In this regime, which BPDG co-chair Andy Setos of Fox
Studios described as an "orderly marketplace," competition is replaced by
gentlemen's agreements between self-interested parties who seek (in the
case of the entertainment companies) to control private use of DTV
programming and (in the case of the technology companies whose
protection technologies are chosen) to shut out their competitors.
In the absence of a broadcast flag mandate, all an innovator needs
to know to build a novel DTV device is what she can find in publicly-
available materials. She need not beg permission of a favored vendor for
some exotic copy-control system nor submit to a private license agreement
governing the scope of her use of that system. She need not add
superfluous tamper-resistance measures that seek to prevent end-users
from modifying her invention or lock out service-centers from performing
minor repairs.
The broadcast flag proposal turns all this on its head. An innovator
in a broadcast flag mandate world needs to build her technology to interact
not with a simple MPEG file, but with a proprietary system whose only
documentation and tools exist at the sufferance of a private licensor. She
is bound not only by the strictures of the art and science, but by any
conditions that the licensors with whom she must treat choose to burden
her with. She can not rely on free/open source software--which
encourages end-user modification--for critical components.
As a result, we can expect that a wide array of innovations will be
slowed or never come to pass as a result of a broadcast flag mandate.
Innovation in this area might include the entry of new manufacturers and
implementers, and the development of new applications of ATSC (and of
8/VSB modulation) as well as new applications for existing
implementations. It might also include a variety of ancillary tools and
technologies that would serve niche markets too small for major vendors
to address. Some innovations that might be imperiled by a broadcast flag
mandate include:

Using DTV content in lawful ways not originally intended,
including with new product categories that might not have
existed when the content was originally captured, as
Macintosh users do when they use Apple's iMovie software
to piece together home movies with excerpts from recorded
TV broadcasts.
Using existing software in lawful ways not originally
intended, including with new DTV programming that might
not have existed when the programs were originally
Manipulating files using free/open source software, and
retaining the ability to repair, modify, and improve that
software and to share improvements with others.
Using any communications or recording medium to transfer
or archive any data.
D. Excludes Free/Open Source Software from the DTV
Free software, sometimes called "open source" software, is a
phenomenon of growing importance in the computer world. Free/open
source software authors release their work to the world in a form that can
be easily modified by other authors, on the condition that those authors
release their modifications under the same terms. Free/open source
software has resulted in a number of significant, industry-standard
technologies. From Apache, the web-server software that powers the
majority of the world's web sites, to Linux, the operating system that is
viewed as the most credible threat to Microsoft's Windows, Free/open
source software powers the Internet and is widely viewed as the most
reliable, least expensive and most flexible form of software extant.
Free/open source software developers are today striving to produce
products that may offer flexible, low-cost DTV solutions to consumers. A
wide variety of video applications--including video recorders, editors, and
players--are now available and are subject to active development.
Innovative free/open source video software like DScaler
is pushing the
boundaries of the art. A variety of applications, both generic video-
processing software and ATSC-specific tools, is under development and
promises to be of use to DTV viewers.
Given the increasing power of general-purpose PCs and the
convergence of PCs and home theater, it is becoming clear that a DTV
receiver can be implemented entirely in software on general purpose PCs,

DScaler is a free/open source video deinterlacer, performing functions elsewhere
implemented in costly hardware products.

using so-called "software defined radio" (SDR) technologies. Given high-
frequency digital samples from a chosen region of the RF spectrum, SDR
receiver software can perform a demodulation function and recover a
representation of the original transmitted signal. As Joseph Mitola III,
who coined the term "software radio," explains, software radio techniques
can be used to implement both transmitters and receivers, with a variety of
As communications technology continues its rapid
transition from analog to digital, more functions of
contemporary radio systems are implemented in software--
leading toward the software radio. A software radio is a
radio whose channel modulation waveforms are defined in
software. That is, waveforms are generated as sampled
digital signals, converted from digital to analog via a
wideband DAC and then possibly upconverted from IF to
RF. The receiver, similarly, employs a wideband Analog to
Digital Converter (ADC) that captures all of the channels
of the software radio node. The receiver then extracts,
downconverts and demodulates the channel waveform
using software on a general purpose processor.

SDR technology is the subject of active research by a broad range
of firms, academic projects, governments, and individuals.
One example
of a Free/open source SDR project aimed at DTV is GNU Radio. It
currently includes essentially complete implementations of FM audio
demodulation, and ATSC video modulation and demodulation functions.

A broadcast flag mandate, to the extent it embraces a "tamper-
resistance" requirement, essentially bans Free/open source software from
the DTV marketplace. By its nature, Free/open source is "tamper-
friendly," in that the software developers freely publish their source code,
intending that others will understand, modify, and improve it.

Joseph Mitola III, "What Is A Software Radio" (available at
The Commission has also begun an examination of the opportunities presented by SDR
technology. See generally In the Matter of Authorization and Use of Software Defined
Radios, ET Docket No. 00-47.

Technology (OET TAC) heard a presentation about GNU Radio on December 4, 2002.

frustrate [User] attempts to modify such Covered Products to defeat the Compliance
Requirements." Broadcast Protection Discussion Group Final Report, Tab C-1,

Should a "tamper-resistance" requirement bar open source
developers from entering the DTV market, a number of important interests
would be harmed. First, insofar as open source software offers a very low-
cost (typically royalty-free) software-based alternative to consumers,
excluding it from the market would harm consumers. Open source
software has also frequently been an important force for ensuring a
competitive marketplace in software, offering a viable competitor to
proprietary software vendors who may otherwise exercise market power.
Finally, because open source software encourages developers freely to
build upon each other's contributions, innovation can be more rapid.
Moreover, insofar as source code has been repeatedly recognized as a
form of speech entitled to First Amendment protections, any broadcast
flag mandate that attempts to proscribe the publication and distribution of
source code relating to DTV reception would tread on the constitutional
rights of software programmers.

E. A Threat to the DTV Transition
By undermining competition, limiting interoperability, frustrating
innovation, and locking out Free/Open Source software, a broadcast flag
mandate is likely to hinder, rather contribute to the DTV transition.
A broadcast flag offers absolutely no benefit to the consumers who
are being asked to purchase new DTV equipment, and may well penalize
early adopters who have made already made substantial investments in
DTV equipment. Instead, a mandate will artificially limit the capabilities
that DTV vendors can offer to the American public. In essence, a

disguise and hamper attempts to discover the approaches used." Id., X.9(b). These
requirements are intrinsically inconsistent with the requirements of free/open source
software. "[A]ccessibility of source code is a necessary condition for free software."

broadcast mandate would force DTV technology vendors to assume that
all of their consumers are "thieves," and treat them accordingly.
History suggests that this is precisely the wrong approach.
Incumbent entertainment industries have repeatedly responded to new
consumer media technologies with initial suspicion and anxiety, decrying
what they perceive as the "thieving" ways of the American public. The
initial concerns, however, have invariably given way to new market
opportunities for those same industries. In several well-known instances,
motion picture studios made confident--and completely erroneous--
public predictions that some new technology would damage their business
For example, when color came to NTSC television broadcast,
major studios were reluctant to broadcast their movies in color. In time,
they recognized that color television was of use to them and began to use
it--not because color television was changed, but because time and
experience validated it, and competitive pressures encouraged studios to
adopt it.

A few decades later, the motion picture industry attacked the
newly-introduced VCR, arguing that the American consumer could not be
trusted with a device capable of recording video content from over-the-air
broadcasts. In the words of MPAA President Jack Valenti before a House
subcommittee in 1982:
But now we are facing a very new and a very troubling
assault on our fiscal security, on our very economic life and
we are facing it from a thing called the video cassette
recorder and its necessary companion called the blank tape.
And it is like a great tidal wave just off the shore. This
video cassette recorder and the blank tape threaten
profoundly the life-sustaining protection, I guess you would
call it, on which copyright owners depend, on which film
people depend, on which television people depend and it is
called copyright.

"The network with the most invested in color, NBC, thus premiered ... the first prime
time series of recent films as Saturday Night at the Movies. Ratings were high and the
other two major networks, CBS and ABC, seeing how poorly their shows fared against
Saturday Night at the Movies, quickly moved to set up their own "Nights at the Movies."

I say to you that the VCR is to the American film producer
and the American public as the Boston strangler is to the
woman home alone.

Ironically enough, in the course of litigating against Sony over the
Betamax VCR, Disney and Universal City Studios suggested that VCR
makers be required to implement a "jamming" system that would respond
to a signal that would be embedded in television broadcasts.
years of history have made it clear that this early version of a broadcast
flag mandate was not necessary. The motion picture industry has since
recognized that the VCR was a much bigger business opportunity than

It is clear that some studios are apprehensive about perceived risks
arising from terrestrial DTV broadcasting. The existence of such
apprehension, however, is not by itself sufficient to justify a federal
technology mandate, especially where the mandate in question would be
ineffective and would exact such a high cost from other stakeholders.
The DTV transition cannot be accelerated through a broadcast flag
mandate--quite the opposite is true.
A broadcast flag mandate presents real threats to consumer
interests and the DTV transition;
The broadcast flag cannot accommodate fair use and other
rights reserved to the public by copyright law;

"[A]n engineer, one Richard J. Stumpf, [...] was supposed to testify to the ease with
which Sony, if it wanted, could make a videotape recorder that served all the legally
innocent purposes of a Betamax and none of the culpable ones. Stumpf had conceived a
system that could render a Betamax incapable of recording a program unless the
broadcaster--presumably on the copyright holder's say-so--chose to let it be recorded.
The system relied on a simple jamming device that could be installed in a Betamax at a
cost, Stumpf was prepared to testify, of less than fifteen dollars a machine." James
Lardner, Fast Forward: A Machine and the Commotion it Caused (Concord, N.H.: Pierce
Law, 2002) (revised ed.), at 104.
Although Congress did ultimately craft a very limited technology mandate for analog
VCRs, requiring VCRs to respond to Macrovision, see 17 U.S.C. 1201(k), the differences
between this mandate and the proposed DTV broadcast flag mandate are striking. First,
the Macrovision mandate was enacted only after more than 20 years of marketplace
competition and at a time when the technology was fully mature. DTV technology, by
contrast, is still in its infancy. Second, the Macrovision mandate applies to only a
narrowly-defined class of products--analog VCRs. The DTV broadcast flag mandate, in
contrast, would apply to a much wider category of products--all devices capable of
receiving DTV.

The broadcast flag will make it harder for consumers to be
confident that their DTV devices will interoperate;
Reduced interoperability and tamper-resistance mandates
will shrink the universe of possible DTV innovations;
A tamper-resistance mandate would impinge upon the First
Amendment rights of Free/Open Source software authors;
By raising the cost and reducing the capabilities of DTV
devices, a broadcast flag mandate will endanger the DTV
VI. Conclusion
For the foregoing reasons, EFF requests that the Commission reject
any broadcast flag mandate that would require devices or computer
programs to respond to the ATSC broadcast flag in any particular way.
