Zoo Atlanta Showcases Endangered Species with Viewcast Technology

DALLAS (Dec. 21, 2000) – When Giant Panda fans from around the world log on to Zoo Atlanta’s PandaCam Web site (http://www.zooatlanta.com/site/the_animals/exhibits/panda_cam.html) to enjoy the antics of Lun Lun and Yang Yang, the zoo’s resident giant pandas, it’s Viewcast technology delivering the amazingly clear streaming video.

Osprey�-200 video capture cards from Viewcast Corporation (NASDAQ: VCST), a leading provider of Internet and networked video solutions, capture and encode the video of Lun Lun and Yang Yang, which has been seen by thousands of people around the world, according to officials at Zoo Atlanta.

Zoo Atlanta’s PandaCam is a terrific application of ViewCast-enabled steaming video. Not only does it give children and adults around the world a unique opportunity to view this endangered species in a natural setting, it also gives the Atlanta Zoo an opportunity to market its fundraising efforts for ‘Save a Species: The Campaign for Giant Pandas’ research program,” said George Platt, Viewcast president and CEO.

The quality of the streaming video for the PandaCam was paramount for Zoo Atlanta, so that people could truly enjoy watching Lun Lun and Yang Yang over the Internet,” said Derek Kolb, Director of Information Technology, Zoo Atlanta. “The Viewcast Osprey Video capture cards delivered the high quality streaming video we needed, and we’ve been very pleased with the results.

The Osprey-200 capture card expands on the capabilities of the Osprey-100, one of the most widely used capture cards in the relatively short history of streaming media. The Osprey-200 features video and audio capture and provides a highly scalable streaming and capture solution. The Osprey-200 also features advanced DMA for ultra-high performance (full 30fps); Direct Draw for 30 frames per second overlays to video screen with minimal CPU utilization; and closed caption capabilities. Additionally, multiple Osprey-200 boards can be hosted within a single PC enabling multi-channel capture and encoding possibilities.
