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.

High Definition Video to the Desktop

FORMATS• MPEG2 MP@HL

• WMV-HD

• H.264/AVC/MPEG4 Part 10

• HDV (MPEG2 MP@H14)

PLAYERS• VLC

• WM9/10

• QuickTime/MPEG4

• VLC


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


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
