 Vista copy protection is defended
Microsoft has defended the digital rights management systems integrated into
its new Vista operating system.

It follows reports that Vista would "downgrade" the quality of all video and
audio, if they were not output via approved connections on the PC.

Microsoft said only the quality of "premium content" would be lowered, and
only if requested by copyright holders.

The measures are in place, says the firm, to protect content such as high
definition movies from being copied.

Vista's copy protection systems have come under fire from many quarters,
including recently from Peter Gutmann, a computer science lecturer at the
University of Auckland.

In a report looking at the impact Vista would have on video and audio
playback, he described Vista's Content Protection specification as "the
longest suicide note in history".

He said Vista was "broken by design" and intentionally crippled the way it
displayed video.

"The sheer obnoxiousness of Vista's content protection may end up being the
biggest incentive to piracy yet created," he wrote.

Enforced

In a response to the paper, Dave Marsh, lead program manager for video at
Microsoft, said many of the copy protection systems enforced by Vista were
common on all playback devices.

He said Vista did have the capability of downgrading video and audio
quality, like other devices, but that it would only be activated "when
required by the policy associated with the content being played".

The copyright holders of content on HD-DVD and Blu-ray discs, for example,
can insist that the video be played back in high definition only if it is
output via a HDMI connection on a PC and into a HDMI connection in a TV or
monitor.

That could prove a problem for many PC users whose graphics cards have a DVI
or component video connection. Microsoft said that if picture quality was
degraded it would still be better than current DVD quality.

Mr Marsh also denied reports that the degradation would impact all video
output, insisting it would only apply to premium content video.

'Very unhappy'

Mr Gutmann told BBC News: "It's reassuring that they are saying that only
the ability to playback high definition video can be revoked.

"But if consumers have gone out and paid thousands of dollars on high
quality, high resolution, high definition displays and find the content is
downscaled or there is no picture at all, they are going to be very unhappy.

"Some of the feedback I have been getting indicates that HD-DVD discs are
not playing on some PCs."

Mr Gutmann also highlighted the extra demands put on a computer's CPU to
handle Vista's Content Protection systems.

Microsoft admitted that the CPU will be taxed further but Mr Marsh said
"Vista's Content Protection features were developed to carefully balance the
need to provide robust protection... while still enabling great new
experiences..."

Mr Gutmann said it was insincere of Microsoft to lay the responsibility for
the increased copy protection systems at the feet of content providers.

He said: "Saying 'we were only following orders' has historically proven not
to be a very good excuse.

"If you have got the protection measures there, the impulse is to use the
most stringent ones at your disposal.

"In general, some sort of DRM is necessary, but we need to strike a balance.
It's very consumer-hostile technology that is being deployed."
