Harmonic, Signiant and Open Text Work With Microsoft to Provide a Better Way for Media and Entertainment Companies to Manage Digital Content

Provide an Integrated Solution to Produce, Manage, Protect, Distribute and
Archive Digital Content
LAS VEGAS--(Business Wire)--
A collaborative group of technology providers - Harmonic Inc. (NASDAQ:HLIT),
Open Text, and Signiant - working with Microsoft announced today at NAB 2009 the
demonstration of an open and integrated approach to providing fast and
cost-effective ways for media and entertainment companies (M&E) to produce,
manage, protect, distribute and store digital content.

"I am pleased to see this collaborative approach being taken to address a
critical need in the market," said Bart Palmer, Senior Vice President of Media
Engineering, Discovery Communications. "As an early technology adopter,
Discovery has traditionally had to build interoperable solutions ourselves,
being able to leverage out-of-the-box integration from these best of breed
products will enable us to significantly lower cost and bring innovative
solutions to our users faster."

Microsoft Corp., Harmonic, Open Text Digital Media Group and Signiant worked in
conjunction to provide a collaborative digital production and distribution
solution enabling M&E companies to overcome the common technical challenges of
managing and moving digital assets around the world. The collaborative solution
is different because it uses an open, service oriented architecture so customers
can integrate applications into their current IT infrastructure. This provides a
single interface for managing digital content every step of the way - from
production and editing to distribution and archiving.

"The rapid rate of change in the global media and entertainment industry makes
it difficult for media and entertainment companies to quickly create products
that enable them to take full advantage of new opportunities and channels," said
Jake Winett, Global Industry Manager for Media & Entertainment in the
Communications Sector at Microsoft. "By integrating our core server
technologies, such as Microsoft Office SharePoint Server 2007 and Microsoft
BizTalk Server 2006, with our partners` applications, we have developed a
digital content management solution that provides more flexible workflows and
improves collaboration for media and entertainment companies."

"This collaboration will give M&E companies a technology advantage so they can
better optimize emerging revenue streams found on the Web, on mobile devices and
in new formats such as high-definition," said Damian Saccocio, VP, Product
Marketing, Open Text Digital Media Group. "This collaborative solution is all
about helping M&E companies find the true value of their content."

"The companies involved in this open collaborative model are dedicated to
helping M&E customers get rid of cumbersome old methodologies that make it
difficult for digital content to be utilized to its fullest potential," said
David Trescot, Vice President of the Rhozet Business Unit at Harmonic Inc. "An
important part of this approach then is making sure one digital format can be
translated and converted to another."

"We are able to quickly and cost effectively move and transform enormous digital
files over the WAN to speed the process of getting content where it needs to be:
in front of audiences," said Robert Browne, Founder and Vice President of
Business Development, Signiant. "It doesn't matter if that audience is in a
movie theater or watching a video on the web."

Developed with TechPath, a Microsoft Gold Certified Partner, Microsoft will be
demonstrating a new solution approach integrated with other third party
applications at Booth SL720 at the NAB Show being held at the Las Vegas
Convention Center, 18-23 April 2009.

The solution will demonstrate:

* Microsoft Office SharePoint Server 2007 for workflow, collaboration, analytics
dashboards and user interfaces. For more information visit Microsoft at NAB
Booth SL720.
* Microsoft BizTalk Server 2006 for process orchestration, web service
integration and task and activity monitoring.
* Microsoft SQL Server 2005 for relational database and cube analytics.

* Open Text Digital Media Group (formerly Artesia) will enable streamlined
workflows for the ingestion, tagging, searching, transforming, and packing of
the media. For more information visit Open Text at NAB Booth SU11417.
