  1. ResearchChannel:Think Forward Michael Wellings, Director, Engineering Dave Robertson, Broadcast Engineer Internet2 Spring Member Meeting Visions ’05: Live HD Video Images from the Seafloor via IP Networks

  2. Topics of Discussion • What is ResearchChannel • iHDTV • What it is • Current state • Planned Software Enhancements • Recent public demonstrations • The Visions ’05 Project • Short video presentation

  3. 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.
