  2. 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.

  3. Pioneering Technology Innovations • 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

  37. 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

  38. Advanced Delivery Methods • The 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

  39. Advanced Delivery Methods It 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 delivery • Global 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
