As Microsoft readies the next version of its Windows operating system,
called Vista, the software giant is building in unprecedented levels of
safeguards against video piracy.

For the first time, the Windows operating system will wall off some audio
and video processes almost completely from users and outside programmers, in
hopes of making them harder for hackers to reach. The company is
establishing digital security checks that could even shut off a computer's
connections to some monitors or televisions if antipiracy procedures that
stop high-quality video copying aren't in place.

In short, the company is bending over backward--and investing considerable
technological resources--to make sure Hollywood studios are happy with the
next version of Windows, which is expected to ship on new PCs by late 2006.
Microsoft believes it has to make nice with the entertainment industry if
the PC is going to form the center of new digital home networks, which could
allow such new features as streaming high-definition movies around the home.

PCs won't be the only ones with reinforced pirate-proofing. Other new
consumer electronics devices will have to play by a similar set of rules in
order to play back the studios' most valuable content, Microsoft executives
say. Indeed, assuring studios that content will have extremely strong
protection is the only way any device will be able to support the studios'
planned high-definition content, the software company says.

"The table is already set," said Marcus Matthias, product manager for
Microsoft's digital media division. "We can come in and eat at the buffet,
or we can stand outside and wash cars."

Hollywood studios didn't get all the protections they wanted in Vista, and
record labels have even seen some of their key concerns about
copy-protecting CDs left unaddressed. But the Vista operating system as a
whole goes much further than any general-purpose computing platform before
it toward addressing content companies' piracy fears.

But these deep changes in the way the operating system handles entertainment
content will also come with costs. The most obvious of these may be the risk
of compatibility problems between some older monitors or TVs and Vista
computers, particularly when trying to play high-quality video. Vista may
also make it harder to do some casual copying, such as recording Internet
audio.

"This is definitely being driven by Microsoft's desire to position Windows
as a home entertainment hub, and to do that they have to make some
concessions," said Matt Rosoff, an analyst with research firm Directions on
Microsoft. "They're walking a line, trying to please both sides (content
companies and consumers) at the same time."

These changes are worrisome to some computer programmers and digital
activist groups. They fear that increasingly high security levels will block
off avenues of programming innovation, or even stop computer owners from
accessing portions of their own machines--a little like walling off a room
inside a private house.

"There is a concern that there is a tendency to lock down parts of the
design to protect the flanks of the copy-protection system," said Princeton
University computer science professor Edward Felten, who has been an
outspoken critic of rigid copy-protection rules. "That makes it harder for
everyone, including Microsoft, to adapt to new uses."

Putting video behind a wall
Several major changes have been made to the way the operating system will
handle video and audio, though few of these are included in the early
version now in the hands of beta testers. The rest of the components will
likely be added in the next, as yet unscheduled, beta release, and will be
in the final launch of the operating system next year.

At the most basic level, some audio and video--at least when it is in
Microsoft's Windows Media format--will be handled in a new "protected
environment" that will keep applications such as media players or plug-ins
separate from the actual media data.
FAQ
Vista's antipiracy shield
Microsoft is working closely with studios in ways that could affect your
home entertainment system. Here's what you need to know.

Essentially, this means that much of the actual heavy lifting of decoding,
unlocking and playing the audio will happen in what some engineers refer to
as a separate "sandbox." Media player applications will send remote control
commands such as play, fast-forward or stop into this protected space,
without directly handling the data as they do today.

Technology called the "Protected Video Path" will then attempt to ensure
that a video stream is encrypted--and thus difficult to copy--all the way
until it reaches a monitor or other device where it is being displayed.

This won't always be possible, because most analog plugs, and some digital
connections, don't support this kind of copy protection. Part of Vista's job
will be to check to see what kind of devices are linked to the computer, and
through what kind of connection, and decide whether the content can be
encrypted or otherwise protected over that link.

If the answer is "no," in the case of high-resolution Video Graphics Array
(VGA) connections, or some early Digital Video Interface connections, the
computer could shut down output of video altogether through those plugs, if
the content owners require that.

Alternately, Vista will include a "constriction" feature that can decrease
the resolution of high-definition video on the fly, outputting a version
that is slightly fuzzier (about the same as today's DVDs) than the pristine
original. This can be used as an alternative to blocking a connection
altogether, if a content company won't let high-definition video play over
the lower-security outputs.

This feature won't affect most HD televisions, which typically are already
shipped with secure connection technologies. PC monitors have been slower to
adopt tools such as Intel's HDCP (High-Bandwidth Digital Content Protection)
that support secure connections, however.

Most of these advanced copy-protection features in Vista are designed to
apply to high-definition content and are unlikely to change the way today's
DVDs or broadcast-quality content is played, Microsoft says.

Labels lack copy-protected CD support
A similar process will happen for copy-protected audio files, potentially
encrypting the audio until it leaves the computer, and offering the ability
to turn off specific outputs if content owners deem them insecure.

For the last year, record labels have sought additional features in the
operating system that would make playing copy-protected CDs a more
streamlined experience. But so far, Microsoft has not added any features
specifically supporting these new CDs, saying that the technology isn't yet
mature, and that other companies--Apple Computer and other music software
companies included--also need to be involved.

"We're seeing digital distribution move at a rapid enough pace that the
rules for which people access content today across the music services are
very consistent," said John Paddleford, lead program manager for the
Microsoft team that works directly with content companies. "This is what
we're driving the labels to reach on the CD itself, so there's a consistent
consumer experience. I think it is going to take time for the labels and the
application vendors--not just Microsoft--to find a middle ground."

A spokesman for the Recording Industry Association of America, which has
engaged in discussions with Microsoft on this issue, declined to comment.

Sensitive subject
Microsoft is aware that the high level of protection--which could result in
some monitors and TVs not playing high-definition content at full
resolution--could spark criticism and confusion.

The company is quick to say that this has not been a case of studios
dictating policy to programmers.

"The studios are very good about not trying to design software," Paddleford
said. "I've never had a studio say, 'We need an API (application programming
interface) that does this.' But they do talk about, 'Well, we want to make
sure that our theatrical content doesn't get played in any place but a
theater.'"

For their part, studio executives say they haven't been involved in the
intimate details, but are happy to see what Microsoft has done.

"The greatest problem in existing operating systems is that content is in
the clear across certain interfaces," said Chris Cookson, chief technology
officer for Warner Bros. "They've undertaken to improve that, which everyone
was glad to see."
