India�s ISRO Selects ViewCast Video Cards for Educational Satellite

Cards encode video for enhanced long-distance learning across nation

DALLAS — Dec. 13, 2005 — The Indian Space Research Organization (ISRO), Delhi, India has selected Dallas-based ViewCast Corporation�s Osprey-230 video cards as part of an expansive program for interactive distance learning and streaming video through its educational satellite, EDUSAT.

The EDUSAT satellite enables nation-wide distance learning by interfacing with video from each school through a system that includes an Osprey-230 at each school site. The ISRO program currently covers more than 1,000 schools and is expected to expand to a network of 10,000 schools within the next three years. ViewCast�s reseller, Rahul Commerce, provided the Osprey technology and associated services to ISRO.

�We chose the Osprey-230s for their quality, functionality and, most importantly, for their reliability,� said A. Bhaskaranarayana, program director of Indian National Satellite Systems. �Satellite technology lends itself to interactive learning and with ViewCast�s help, we hope to bring learning opportunities to thousands of children and adults in remote towns and villages.�

EDUSAT beams local language instructional programs and employs digital interactive classrooms to address illiteracy caused by a lack of trained teachers in rural India. For example, one interactive program lets students send video questions to any teacher in any connected classroom, anywhere in India, via the Osprey-230 streaming video over the EDUSAT satellite. The teacher then returns answers through EDUSAT.

�Streaming media overcomes geographical obstacles and can reach people regardless of their locations, making it a perfect solution for distance learning. Our products help institutions such as the ISRO reach their audiences anytime and anywhere,� said Dave Stoner, president and COO of ViewCast.
