ViewCast Osprey SimulStream Goes Digital

Popular Software Now Provides Multiple Audio and Video Streams for Digital Capture Cards

DALLAS(Nov. 20, 2001) - ViewCast Corporation (NASDAQ: VCST), the video communications leader, announced today that its innovative Osprey SimulStream(TM) software, which gives users the ability to output multiple video and audio streams settings using multiple encoding applications with independent capture settings from a single Osprey capture card, is now available as Osprey Digital SimulStream to users of Osprey-500 line of products.

For the Osprey-500 DV and DV Pro models the Osprey Digital SimulStream software solution provides cost-effective capabilities in DV and pro audio/video source distribution to software applications. This unique new offering creates a ``virtual splitter'' of video and audio from either DV or SDI sources. Professionals can now process media from digital sources simultaneously, substantially improving production workflow and saving valuable time.

Streaming media content creators typically encode several different streams of the same media in order to provide streams for modems and broadband connections, as well as for different formats, such as RealNetworks�, RealVideo�, and RealAudio� and Microsoft's Windows Media. Before Osprey's SimulStream offerings, content creators had to repeat the encoding task for each file, or use multiple cards to speed up the process. With Osprey SimulStream, multiple encoding tasks can be launched simultaneously on a single computer. Osprey SimulStream reduces encoding time up to 83 percent while greatly improving the video and audio on the resulting streams.

"Three of the biggest challenges for our customers are the quality, cost and workflow of content creation,'' said Kevin Foreman, general manager, Developer and Partner Relations, RealNetworks, Inc. ``The combination of the industry's highest quality codecs -- RealVideo 8 and RealAudio 8 -- with Osprey's new SimulStream software, makes huge strides toward overcoming these obstacles of programming quality, hardware costs and personnel intensive workflow."

"SimulStream is a new concept to the streaming media world and will fundamentally change the way a lot of streaming media is created,'' said ViewCast President and Chief Executive Officer George Platt. ``Professional broadcasters want to reach the broadest possible audience, and the availability Osprey Digital SimulStream allows them to distribute digital content from a single source to a variety of different applications. This substantially improves streaming encoding workflow, saving both time and money."

Osprey SimulStream was introduced in October as an exclusive product for ViewCast Osprey� Video Osprey-210 and Osprey-220 capture cards. Osprey SimulStream is also provided as part of ViewCast Systems package offerings in Niagara(TM) Streaming Systems that utilize the Osprey-210 and Osprey-220 for their capture engines. ViewCast plans to offer support to the digital Osprey-2000 by the end of the year.

The Osprey-500, hailed by Streaming Media World as the ``Rolls Royce of the industry,'' 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.
