ViewCast Introduces First Streaming Capture Card Combining Analog and Digital Video Capture for Under $500

Osprey�-300 Addresses Both Streaming and Video Editing Applications

DALLAS — April 20, 2004 — ViewCast Corporation (VCST.OB), a leading global provider of high-quality video communications for businesses and media enterprises, has announced the launch of Osprey-300, establishing an introduction into the nonlinear editing market. The Osprey-300 combines the quality and superiority of the industry-leading Osprey Video streaming capture cards with the features of a standard IEEE 1394b card, creating a quality digital video (DV) capture card with full device control capability. The Osprey-300 is also the first ViewCast capture card to be certified for Adobe� Premiere� Pro, Adobe�s award-winning non-linear editing software.

"The Osprey-300 is a price-performance breakthrough,� said George Platt, president & CEO of ViewCast. �We�re essentially delivering two cards for the price of one and then offering it bundled with the industry�s leading creative software, all at an extremely attractive price. Additionally, it enables media production teams to optimize streaming time in the post-production process, more efficient use of editing equipment, and assurance of the high integrity of the original images."

Building upon the video streaming and high-performance features of the Osprey-230, the Osprey-300 adds OHCI-compliancy (IEEE-1394) for video capture. The Open Host Controller Interface(OHCI) compliant IEEE-1394 standard allows users to transfer DV material into an editing system in its native DV format while maintaining original source quality and optimizing the workflow for post-production houses. The PCI-X bus interface provides compatibility with the latest PC technologies, delivering high-performance/high-bandwidth data transfers.

In addition to the launch of Osprey-300, and its certification for Adobe Premiere Pro, ViewCast is in the process of being certified for the future release version of Premiere Pro 1.5, which was announced at NAB. Together, the Osprey-300 and Adobe Premiere Pro deliver high-performance capture and device control for real-time editing.

"With the certification of the latest Osprey-300 video card, Adobe Premiere Pro users have access to a strong, affordable option for editing and streaming capture of desktop digital video," said Ron D. Nydam, senior product manager for Adobe Premiere.
