THE BBC SEEKS ESCAPE FROM PATENT MINEFIELD


By Neil McAllister

It seems like everywhere you look, open standards and open formats are
becoming the preferred means of delivering digital documents. XML, for
one, is now the darling of the enterprise: Even Microsoft has committed
to an open XML format for its upcoming Office 12 suite. But whereas
static, printable document formats become more and more universally
open, the picture isn't so rosy for multimedia.

The BBC wants to change that. Supported by public funds, the BBC is
committed to providing free and open access to audio and video media to
a wide audience. But even for the largest broadcast media organization
in the United Kingdom, breaking the grip of proprietary digital media
standards isn't going to be easy.

Think of any popular multimedia file format and you're probably thinking
of a corporate brand. RealVideo, QuickTime, Windows Media -- each name
is a trademark, with the inner workings of each format a closely
guarded, proprietary formula. Even MP3, a name now virtually synonymous
with intellectual property theft, contains intellectual property -- in
this case, patents held by Fraunhofer-Gesellschaft .

Not that there's any shortage of open standards in the multimedia
industry. After all, standards put forth by the Moving Picture Experts
Group, or MPEG for short, are found in everything from DVD movies, to
videoconferencing, to MP3 audio. Yet multimedia remains a veritable
minefield of patents. In fact, so many patents apply to the simple act
of playing compressed video on a computer screen that it would be
virtually impossible to develop any kind of multimedia application
without an industry consortium such as the MPEG committee.

The way consortiums work is that the various patent holders join an
industry group and agree to let their patents become part of that
group's standards. In so doing, they agree to license their technologies
under the blanket terms agreed on by the consortium. In the case of
MPEG, that means "reasonable and nondiscriminatory" licensing terms.
Anybody is free to license MPEG standards -- nobody can be shut out --
just as long as they pay the fees.

The obvious losers in that kind of deal are open source projects, which
often are but loosely knit groups of individuals in no position to pay
any kind of fee, no matter how "reasonable." But potential users of
those projects lose, as well. Consider the growing number of people in
the developing world who rely on open source for all their computing
needs, and you'll see how patent-encumbered technologies do not pose a
long-term solution for a media organization with a mission similar to
the BBC's.

To push past this encumbrance, the BBC took an unorthodox step: It
decided to develop its own multimedia codec. Called Dirac, the new
format is fully open source, supports high-resolution video, and
promises a twofold increase in compression compared with current MPEG
standards at the same video quality. The final release is due before the
end of the year, but experimental versions are available now. The
VideoLAN  project, for one, has built preliminary support for Dirac into
the latest version of its open source VLC multimedia player, released in
late June.

How can the BBC be sure it isn't just walking into another hidden patent
bomb? It can't. Especially with so much intellectual property at stake.
To hear more about the BBC's prospects -- and the future impact of
patents on European technology businesses -- tune in next week.
