ViewCast Announces Niagara® PowerStream for High-Bandwidth Streaming

New Streaming System Addresses Performance Needs for Broadband Business Video Applications

DALLAS (April 29, 2003) - ViewCast Corporation (VCST.OB), the video communications leader, announced today the availability of its new Niagara® PowerStream, a premium 2U rack-mount streaming media encoder designed for the high-bandwidth streaming of corporate and business video communications. The Niagara PowerStream addresses broadband needs for security/surveillance, training, corporate video, and business TV applications.

Streaming encoding software engines such as Windows Media Encoder and Real Helix Producer are becoming more CPU intensive with each software release as the demand for high-bandwidth streaming of business video continues to grow. More advanced solutions are required to provide businesses with the high-quality content they seek to deliver, plus meet the processing demands of the most popular streaming engines. With the introduction of the Niagara PowerStream systems, ViewCast offers the most powerful streaming solutions addressing the growth of high-bandwidth content delivery.

"The Niagara PowerStream enables medium to large corporations to quickly and easily take advantage of the high-bandwidth streaming media benefits within their enterprise," said George Platt, ViewCast President and Chief Executive Officer. "Based on customer feedback, ViewCast designed the Niagara PowerStream to meet the rigid requirements of broadband streaming, specifically for business video applications."

The Niagara PowerStream is part of ViewCast's family of the Niagara rack-mountable and portable turnkey streaming systems for business video applications. Niagara Streaming Systems incorporate ViewCast streaming software tools which include SimulStream™, for simultaneous multiple bit rate/multiple format streaming and capture from a single video source, plus Niagara SCX™, which enables remote monitoring and control of multiple or distributed streaming encoders, via a single encoding interface.

The Niagara PowerStream features a dual Intel® Xeon™ 2.4 GHz processors, 1GB RAM, and two 80GB ATA drives, via RAID 0 (160GB total). Powered by ViewCast's industry-leading Osprey® video capture cards, the Niagara PowerStream's audio and video inputs include SDI, DV, S-Video and composite (BNC) video, as well as embedded SDI, AES/EBU, and B/UB audio.
