ViewCast's Acclaimed Osprey-500 Now �Streaming Neutral,� Available To All Applications

DALLAS (Sept. 4, 2001) - ViewCast Corporation (NASDAQ: VCST), the video communications leader, announced today that the popular Osprey-500 video capture card, originally designed in close collaboration with Microsoft, is now "streaming neutral" and supports all software applications requiring capture from digital and analog video/audio sources such as cameras and tape decks.

In addition, prices have been reduced, effective Sept. 3, to $895 � a 10 percent reduction � for the analog/DV-only model and $1995 � a 20 percent reduction � for the fully featured DV Pro version.

"ViewCast's Osprey products have long been dominant capture cards in the streaming market thanks to outstanding technology and dynamic partnerships," said Neal Page, senior vice president and general manger of ViewCast's Osprey division. "I would like to acknowledge Microsoft's contribution to this product and its significance for professionals who required the uncompromised quality of digital sources for their streaming content. We are pleased to make the Osprey-500, a card hailed as the �Rolls Royce of the industry� by Streaming Media World, truly streaming neutral to address the broader workflow and format requirements of the greater streaming market."

Previously, the Osprey-500 only enabled the Windows Media Encoder to create a Windows Media streaming format directly from a video/audio source and WMCap, an audio/video capture application, to capture raw media from the Osprey-500 to an AVI file. This limited the market for the Osprey-500, as some content-creation workflow environments utilize other applications for pre-processing, editing, and conversion to different streaming and archive formats.

Effective Sept. 5, new drivers for the O-500 will be available for free download from www.ospreyvideo.com. Making the Osprey-500 streaming neutral gives customers the ability to use the Osprey-500 with a broader range of software applications � including Windows Media Encoder, RealNetworks� RealSystem Producer, Adobe Premier 6.0, Media 100�s Cleaner 5, Sorrenson Broadcaster and other leading applications � as well as streaming directly to Windows Media and Real formats.

The Osprey-500 is the first professional-grade video capture card designed specifically for the capture of broadcast-quality digital video for streaming media. The Osprey-500 creates pure end-to-end digital video for streaming and removes video-quality degradation caused by the multi-step video-conversion process of the first generation of existing capture cards and software. It also allows anyone with a digital video (DV) camera to plug into the world of streaming media without any loss in quality.
