Nevertheless even open HDMI is not very attractive for pirates because the
signal is not compressed. And it is very expensive to re-compress with good
quality. To manufacture without HDCP license will be risky for the
manufacturer and will mean short lifespan for that brand

Subject: [opendtv] Intel: Leaked HDCP copy protection code is legit
Well, there may be a development that is going to throw the distribution of
all content into question.
HDCP now has it's own "deCSS" problem.

Intel has confirmed that code posted to the Internet earlier this week is
the master key that is part of an Intel-created standard used to make sure
only authorized devices are playing copyright-protected movies.
"We can use it to generate valid device keys that do interoperate with the
(High-bandwidth Digital Content Protection) protocol," Intel spokesman Tom
Waldrop told CNET today.
HDCP is used in set-top boxes, DVD, and Blu-ray disc players, and other
devices to encrypt the content, audio, or video, and verify that the devices
have HDCP licenses and thus won't play pirated content.
The code appeared mysteriously on the Pastebin.com site on Monday with the
headline "IS THE LEAKED HDCP MASTER KEY REAL?"
It remains unknown who posted it and how they were able to get the code,
Waldrop said.
With the master key code it is possible to build devices that play
copyright-protected content without having to pay for licenses. But Waldrop
said that wouldn't be easy to do because the technology would have to be
implemented in the chip. "As a practical matter, that's a difficult and
costly thing to do," he said.
And Intel most definitely would try to thwart any makers of unauthorized
devices.
"We believe that this technology will remain effective," he said. "There's a
large install base of licensed devices including several hundred licensees
that will continue to use it and in any case, were a (circumvention) device
to appear that attempts to take advantage of this particular hack there are
legal remedies, particularly under the DMCA (Digital Millennium Copyright
Act)."
