ViewCast Delivers Macromedia Flash Video Streaming at NAB 2004

Osprey cards capture and encode video for Flash

DALLAS — April 19, 2004 — ViewCast Corporation (VCST.OB), a leading global provider of high-quality video communications for businesses and media enterprises, today announced at NAB 2004 that their Osprey streaming cards can be used to deliver real-time video to Macromedia� Flash� Player, opening up a significant range of applications for ViewCast users. The ViewCast streaming products seamlessly deliver quality video that can be displayed through Flash Player via the Macromedia Flash Communication Server MX or the Macromedia Flash Video Streaming Service.

Macromedia Flash Player supports live streaming video, delivered with ViewCast Osprey video streaming cards, and Macromedia will be demonstrating VOD and live streaming in its booth at NAB 2004 (booth # SL1248). Macromedia Flash Communication Server MX includes the ability to stream live to the Flash Player for cross-platform streaming, and the ability to synchronize graphics and text with the video stream for superior presentation and display capabilities.

"ViewCast is a great addition to the Macromedia Alliance Partner Program,� said Chris Hock, director of product management, Macromedia. �Simply by plugging a digital video camera directly into a ViewCast Osprey card, live streaming will be available to approximately 500 million online users. This capability will simplify the whole process for content providers who want to work with video on the Internet and in other live video streaming applications."

"The relationship with Macromedia enables ViewCast�s extensive installed base of users to enjoy many expanded capabilities,� said George Platt, president and CEO of ViewCast Corporation. �One significant advantage is that no upgrades to the ViewCast cards and software are necessary, therefore our users can rapidly develop new delivery applications using Flash and incorporate video captured by ViewCast. Additionally, we now have the capability to offer new video streaming enhancements to the large installed base of Flash developers."

ViewCast video capture cards will also be used to support Macromedia Breeze -- the rich-media communications and authoring solution that expands the abilities of organizations to conduct on-line meetings and distance learning programs. Breeze users can use ViewCast cards to integrate real-time streaming video for VOD, live events, IP video conferencing, and real-time collaboration applications.
