SAN MATEO, Calif.--(Business Wire)--

mobile and Internet test & measurement solutions for continuously
improving the online experience, today announced both Microsoft and
CCTV selected Keynote Streaming Perspective(R) for robust performance
monitoring of streaming video of the 2008 Olympic Games in Beijing.

Keynote was selected by Microsoft to monitor the performance of
2,200 hours of streaming video of the Olympic Games on NBCOlympics.com
on MSN in the U.S. as a result of Keynote's ability to expand the
Streaming Perspective product to include Microsoft Silverlight 2.
Additionally, CCTV, the company that originates much of the Olympics
coverage from China, also selected Keynote Streaming Perspective to
ensure the protection of the copyrighted online streaming video of the
Olympic Games.

The Beijing Olympics generated more streaming video, both live and
on-demand, than any other event in history with a wider variety of
sports delivered to more audiences than in any previous Olympics.

Silverlight, Microsoft's cross-browser, multiplatform plug-in for
delivering the next generation of media experiences and rich
interactive applications via the Web, enabled Olympics fans to not
only watch and pause thousands of hours of live Olympics coverage
online, but also offered rewinding and replaying capabilities for
viewers to re-live historic Olympics moments or catch the technicality
they may have missed.

"We are pleased to have worked with Keynote to test and monitor
the performance of the Olympics video coverage streamed via
Silverlight 2 on NBCOlympics.com on MSN," said Brian Goldfarb, Group
Product Manager, Developer Platforms team, Microsoft Corp. "Keynote's
deep understanding of our technology requirements and our companies'
commitment to customers helps ensure we are delivering an exceptional
experience to our online viewers."

"We're pleased to have worked with both Microsoft and CCTV on such
a historic event," said Umang Gupta, CEO of Keynote Systems. "This
year marks the most ambitious effort to enhance and expand the
experience of the Olympics by bringing thousands of hours of live
streaming video online. Both Microsoft and CCTV demonstrated their
commitment to the end-user experience by working with Keynote's global
test and measurement network to ensure viewers are able to enjoy their
favorite Olympics moments."

"Streaming video for the Olympics was no easy task," said Jian

Perspective allowed us to effectively manage the copyrighted Olympic
