What Is ResearchChannel?
As a consortium of universities and research institutions, we are an intellectual community that makes knowledge available to all by sharing our developments, insights and discoveries with a global audience. We bring together ideas from the world’s premier institutions and disseminate those ideas to the public directly. We engage our audience in the research process by communicating developments as they unfold. We experiment with technology to enable alternative, leading-edge exchanges of our resources.We are committed to looking forward, both in terms of our technological innovation and our continual diversification and expansion of resources for our audience.

Advanced Delivery MethodsThe content is important, not the delivery method
• We will use what works best for the application• Quality will scale to match the receiving device
Multiple delivery methods will be used• Wired delivery for stationary receivers• Non-wired delivery for mobile devices
As high speed connectivity proliferates, over-the-air transmission becomes less important for stationary receivers
• The multiple use, highly connected devices in the home receive all content over high speed network connections using several forms of transport media
Ip over cable, fiber, copper, RF• CATV operators will migrate to an all-IP delivery scheme and
broadcasters will be hard-pressed to compete • Traditional Broadcasting’s last stand will be rural areas in advance
of expanding IP networks
Think Forward. Think ResearchChannel.
Advanced Delivery MethodsIt took about a year for cable modems downstream speeds to
increase from 2mbps to 8mbps in the Seattle area
High bandwidth connectivity means non-linear viewing of multi-res content which will change the face of media deliveryGlobal reach
Old Model:• Broadcast in your own geographic area• Compete with local broadcasters and print media
New Model:• “X-cast” (Podcast, multicast, unicast etc) to the world and
become part of an immense soup of content• Compete with everyone for a small slice of a universal market
