(This deserves reading.....and is quite disturbing.  Also like how Longhorn
will consider this form of DRM a "security" requirement.  It sure doesn't

The Clicker: Microsoft¹s OPM for the masses

Every Thursday Stephen Speicher contributes The Clicker, a weekly column on
television and technology:

A lifetime of computing has taught me one thing: shortly after a new
operating system hits the shelves, I end up upgrading my computer.

Oh sureŠ I do my best to limp along with the ³antiquated² hardware. After
all, my computer is always well within the minimum specs. However, despite
my best efforts, the story always unfolds the same way: I begin to crave the
speed. I drool over the new features. I want the latest and greatest. In
short, I fold like a cheap suit, and I upgrade.

The one bright spot in the upgrade process has always been the monitor. Like
the North Star, the monitor is always there to ease the transition. I look
to it for comfort, and it stares back at me as if to say, ³It¹s OK, Buddy;
I¹m here for you. You¹ll always have me.² Sure, monitors can get a big dated
(think dirty beige 14-inch CRT), but when have you had to upgrade your
monitor to avoid functional problems in the new OS?

That all changes with Longhorn.

Why? With Longhorn, Microsoft will begin pushing opium. Well, technically
it¹s OPM. However, opium might be a good option for those livid that the
video content being sent to their pristine 24-inch Dell LCD monitors is
purposefully being ³fuzzied² (more on that later).

So what is OPM? The successor to Microsoft¹s rarely-mentioned COPP
(Certified Output Protection Protocol), PVP-OPM (Protected Video Path ­
Output Protection Management) is the first play in Microsoft¹s game plan to
ensure that protected content stays protected. PVP-OPM performs two main
functions. First, it detects the capabilities of the display devices
attached to the computer. For instance, does the DVI LCD monitor that you¹re
using have HDCP (High-bandwidth Digital Content Protection)? Second, it
manages what, if anything, gets sent to those devices.

If you¹re one of those rare people whose display is equipped with HDCP,
you¹re fine. However, in the world of computers, those users are few and far
between. While HDCP has become the de facto standard for display
copy-protection in televisions, its penetration in the computer display
market would be pleased to merely be called anemic. Whether you¹re plunking
down money for one of the new ultra-fast LCD displays with 4ms response
times or you¹re becoming the envy of neighborhood with Dell¹s UltraSharp
2405FPW widescreen display, you¹re buying a monitor that won¹t play nice
with premium content in Longhorn.

So what will happen when you try to play premium content on your
incompatible monitor? If you¹re ³lucky², the content will go through a
resolution constrictor. The purpose of this constrictor is to down-sample
high-resolution content to below a certain number of pixels. The newly
down-sampled content is then blown back up to match the resolution of your
monitor. This is much like when you shrink a JPEG and then zoom into it.
Much of the clarity is lost. The result is a picture far fuzzier than it
need be.

That¹s LUCKY?

It sure is ‹ when the alternative is a black screen. If OPM determines that
your monitor falls below the security restrictions (i.e. isn¹t DVI or HDMI
w/HDCP), you could be greeted with a ³polite message explaining that [your
monitor] doesn¹t meet security requirements.²

Who determines when you get the restrictor and when you get the black
screen? You guessed it: the content owner does.

³But I use VGA with my monitor,² you say. Too bad. Unless you upgrade your
monitor, you too will be hoping your content provider opted for the
blurry-but-visible protection mechanism.

Microsoft is quick to point out that many content providers have agreed to
not totally block all analog displays. Instead they have agreed to
compromise and allow the constricted (down-sampled) versions to pass
through. Still ‹ this is a far cry from enjoying the unmolested goodness of
hi-def content.

To be fair ­ it¹s not just Microsoft. The next generation of digital content
will, by and large, be protected to the display. Recently Toshiba released
their HD-DVD specifications and have dictated HDMI/HDCP as a display
requirement for playing back high-definition content. Most expect Blu-ray to
have similar restrictions.

What makes the PC situation so insidious is that nearly every monitor being
sold today will fall victim to this gotcha. Blame whomever you like (the
monitor manufacturers should shoulder their portion of the blame too), just
be careful when buying a monitor these days. Or at least know that you could
be setting yourself up for disappointment.
