IBM’s xCP Puts a Twist on Content Protection

IBM Corp. on Monday lifted the veil of secrecy surrounding
xCP (eXtensible Content Protection), the digital rights protection
architecture that promises to solve the riddle of portability for content

Big Blue used the spotlight of the National Association of Broadcasters
(NAB) annual conference to showcase the goodies from its Digital Media
Factory and finally unveiled the xCP initiative which puts a twist on
content protection by allowing access to DRM-protected media on and off the

The new technology, which builds on Big Blue’s existing CPRM and CPPM
digital rights management technologies, requires little or no Internet
connectivity and works by allowing all of the devices within a “home”
network to establish common media keys. The unique IDs distinguish each
device in the network from other devices, preventing use (viewing or
listening) of the content by devices outside the
network, the company explained.

For content producers, xCP releases the noose on media content beyond the
PC and extends content to network devices. It allows “fair use” mobility
within a household network and, at the same time, prevents unauthorized
digital content distribution from one household to another.

The xCP technology, based on IBM’s Cluster Protocol, works by assigning a
key within each household that’s embedded into devices like MP3 players, DVD
players, cell phones, PDAs, televisions and entertainment systems in
vehicles. They key then unlocks copy-protected content on all the

Big Blue said xCP can be linked with IBM Web Services technology to
provide a platform to physical media and the necessary network architectures
to enable commerce on any platform. xCP supports plug-n-play functionality
for a limited number of devices. For example, the company said, a user might
play content seamlessly on his home theater in one room of a house. When a
wireless audio player, for example, is purchased for use in another room in
the house, this new device automatically joins the domain and has access to
the existing content.

Even as it unlocks DRM beyond the PC, the protection technology lets
content owners retain control over the distribution of content. “If a user’s
friend were to download some of the user’s files, the content would not work
on the friend’s player without first acquiring an additional license,” an
IBM spokesperson explained.

IBM also used the trade show to debut Digital Media Center (DMC), an
infrastructure for broadcasting and entertainment that offers a digital
video storage system built on open standards.

The new Digital Media Center comes equipped with IBM FAStTStorage, IBM
eServer pSeries severs running on AIX, IBM eServer xSeries servers running
on Linux, IBM General Parallel File System (GPFS), and IBM Global Services
Integration services to install and manage new digital broadcasting

The line of FAStT disk storage servers lets customers to create small
high-bandwidth Storage Area Networks (SAN) that support a variety of
operating systems.
