HD Video Streaming Reaches New Quality and Performance Levels with ViewCast's
Niagara 7500

PLANO, Texas, April 7 /PRNewswire-FirstCall/ -- ViewCast Corporation (OTC
Bulletin Board: VCST), a developer of industry-leading hardware and software
for the transformation, management and delivery of professional quality video
over IP and mobile networks, today announced they will be demonstrating the
Niagara(R) 7500, their latest innovation in high-definition streaming, at NAB
2009. The Niagara 7500 is a powerful, feature-rich streaming appliance for
Web-based delivery of high-definition video. Designed for the most demanding
professional broadcasting applications and other professional-level
high-definition video distribution requirements, the Niagara 7500 is a
complete plug-and-play solution that enables users to quickly capture and
broadcast premium quality audio and video to IP and mobile networks in
multiple formats and at multiple bit rates - all simultaneously.

"The Niagara 7500 combines the latest multi-core processing power with
ViewCast's advanced video processing and comprehensive encoding capabilities
enabling broadcasting professionals to deliver the highest definition,
multi-standard video streaming experiences that today's digital media
marketplace demands," said Dave Stoner, ViewCast President and CEO. "Even more
significantly, our management tools simplify the complex workflows often
associated with the transformation and delivery of HD sources to IP and mobile
networks."

The Niagara 7500 is a high-definition video-streaming appliance that brings a
new level of quality and performance to professional broadcasting
applications. It offers a sleek, innovative touch control interface that
streamlines and simplifies operation. A brilliant high-resolution widescreen
monitor on the front panel displays captured video, and multi-segment LED
meters and a headphone jack are provided for audio monitoring.

The Niagara 7500 accepts standard or high-definition video through its SDI
interface, and an SDI loop-out is provided to facilitate workflow. A key
feature of its video processing capability is that it can switch-on-the-fly
between standard and high-definition sources, without having to re-initialize
the system. Audio inputs include analog stereo (balanced and unbalanced), two
channels of AES/EBU, and eight stereo pairs of embedded SDI audio.

The Niagara 7500 also comes standard with ViewCast SimulStream(R) technology,
which enables a single video source to generate several video streams all at
once, with each stream configured differently for laptops, cell phones, or
mobile devices. It also allows simultaneous streaming in many popular formats,
including Windows Media(TM), VC-1, Silverlight(TM), Flash(TM), H.264, 3GPP
mobile and more.

Closed-caption extraction and rendering, de-interlacing, and inverse telecine
are standard on the Niagara 7500, as well as bitmap overlay, scaling and
cropping. If its incoming signal is interrupted, the Niagara 7500 will even
default to a standby message that can be customized by the user.

Like all professional-grade ViewCast streaming appliances, the Niagara 7500
comes standard with Niagara SCX(R) Pro, which allows remote management of all
the key features of multiple units in the same easy-to-use interface, over the
network. There's also an available SDK that allows users to customize their
experience, or interface with broadcast automation systems for highly
customized applications.

NAB 2009
ViewCast will be demonstrating the Niagara 7500 along with the company's
latest products at NAB 2009, April 20-23, Booth SL6020, at the Las Vegas
Convention Center. To schedule an appointment with a ViewCast executive at the
