  RGB Networks Demonstrates New Dynamic Bandwidth Manager Delivering 50
     Percent More VOD Content Without Requiring Additional Bandwidth

    Industry’s only real-time VOD bandwidth manager preserves SD and HD picture quality

ORLANDO, FL – June 20, 2007– Here at its Cable-Tec Expo booth (#2480), RGB Networks,
the leader in network video processing, is demonstrating the bandwidth efficiency of its new
Dynamic Bandwidth Manager (DBM) which enables cable television operators to deliver up to
50 percent more video-on-demand (VOD) programming without increasing bandwidth or
impacting picture quality.

In the demonstration, attendees will see side-by-side comparisons showing unmodified,
standard definition (SD) and high definition (HD) VOD programs next to SD and HD VOD
programs that have been ‘bandwidth optimized’ by the DBM with no discernable change in
picture quality. The DBM reduces the bandwidth requirements of VOD programs by processing
them in real-time from the constant bit rate (CBR) they are typically delivered in, converting
them to a variable bit rate (VBR), which frees considerable bandwidth. The demonstration
shows an SD program that has been processed sufficiently to fit 15 VBR VOD programs into a 6
MHz 256-QAM channel, compared to the 10 CBR programs carried in most SD VOD
deployments. The demonstration will also show a substantial bandwidth savings for HD,
enabling operators to deliver three HD VOD programs per channel, compared to the two
programs typically delivered.

“We specifically designed our Dynamic Bandwidth Manager to achieve significant VOD
bandwidth savings while simultaneously preserving optimal picture quality and ensuring that
subscribers experience no noticeable differences when using VOD’s fast forward, rewind and
pause ‘trickplay’ features,” said Kerry Washington, RGB’s Technical Marketing Manager
responsible for the DBM. “Our Cable-Tec demonstrations show that the DBM can meet
operators’ goals of delivering more VOD programming without resorting to node splits and other
costly methods for increasing bandwidth and without affecting the end-user experience.”

Complementing its bandwidth optimizing capabilities, the DBM is exceptionally easy to deploy
as it processes VOD programs in real-time, eliminating the need for complicated pre-processing
of the programs and any complex integration with VOD servers. Operators simply ‘plug’ the
DBM into existing VOD deployments as it is compatible with all the major components of an
end-to-end VOD system, including VOD servers, resource managers and quadrature amplitude
modulation (QAM) modulators. The DBM can also encrypt each VOD program as it is
processed, making it dramatically easier for operators to continually add new programming to
their VOD line-ups compared to solutions which require extensive pre-processing of the content.

Another advantage of the DBM’s real-time processing is that it can also be used in switched
digital video (SDV) architectures, unlike pre-processing and non-real-time based solutions which
cannot work with live broadcast programs.
