The ResearchChannel Consortium
An intellectual community, we make knowledge available to all by sharing our developments,insights and discoveries with a global audience.
We bring together ideas from many of the world’s premier academic and research institutions and disseminate those ideas to the public directly,without interference.
We are committed to technological innovation toenable leading-edge exchanges of our resources.

Why?
To advance global networking technologies
To explore new methods of media distribution and sharing for teaching learning and research
To further multidisciplinary multinational scientific collaboration
Because the consortium is uniquely qualified to do so
Think Forward. Think ResearchChannel.
ResearchChannel is a collaboration among experts in Internet networking, storage/search infrastructure development, emerging streaming media and interactive technologies, digital television engineering, and video production.
On the Leading Edge
