World's first long-distance Super HD transmission over IP network

Japan's Nippon Telegraph and Telephone (NTT),
in collaboration with the University of Illinois at Chicago (UIC) Electronic Visualization Laboratory (EVL) and the University of Southern California (USC) School of Cinema-Television, successfully demonstrated Super High Definition (SHD) full motion digital imagery streaming in real time from a server in Chicago to a projector in Los Angeles.

This was the world's first successful trial of long-distance transmission of SHD content over general-purpose IP networks.

SHD has four times the resolution of HDTV, and 24 times the resolution of standard definition video. Transmission of SHD via network requires sustainable high-speed connectivity of 1 Gbps over multiple 'hops' without significant packet loss, delay or jitter.

The demonstration, done as part of Internet2's Fall 2002 Members Meeting in Los Angeles, shows the potential for super high performance imaging and visualisation applications over very high-speed networks.

The content, 3840 x 2048 SHD video, came from scientific instruments, computer graphics simulations, digitally scanned motion-picture films and digital still cameras. The imagery was successfully streamed from an NTT content server at StarLight, the National Science Foundation-sponsored optical exchange for advanced networks in Chicago, over the Internet2 Abilene backbone, to the USC Robert Zemeckis Center for Digital Arts.

The content, pre-compressed to 200-400 Mbps using an experimental JPEG 2000 SHD codec, was received in Zemeckis Center by an NTT real time decoder, then fed to NTT's prototype SHD frame-buffer and eight megapixel full-colour D-ILA projector for display on a large screen.

HDTV and other high bandwidth applications supported
Amsterdam, Netherlands - September 19, 2002 - The first long-term, trans-Atlantic 10 gigabit per second wavelength circuit dedicated to research and education, provided by Tyco Telecommunications to the Internet Educational Equal Access Foundation (IEEAF), and provisioned from the US to Europe through the efforts of Internet2 and SURFnet, will be inaugurated at iGrid2002 with a demonstration of uncompressed HDTV over IP sponsored by the Pacific Northwest Gigapop and the Research Channel.

The connection is provided as part of a long-term commitment by Tyco Telecommunications to the research networking community through an agreement with the non-profit organization IEEAF. Internet2, the consortium led by US universities focused on accelerating the development of the Internet, and SURFnet, the Dutch national research network and hosts of iGrid2002, have put the 10 gigabit per second circuit into operation between their networks in New York and Amsterdam.

The trans-Atlantic connection was established in time to support iGrid2002, the biennial International Grid applications-driven testbed event being held this week in Amsterdam. iGrid2002 showcases how extreme networks, combined with application advancements and middleware innovations, can advance scientific research. One of many applications showcased, the 1.5 Gbps uncompressed HDTV stream from Seattle to Amsterdam used the new Tyco Telecommunications link.

The 10 Gbps connection is made possible by a five-year commitment by Tyco Telecommunications to the IEEAF, a non profit organization whose mission is to realize the opportunities in the global telecommunications marketplace on behalf of the research and education community. "Our goal is to enable the 'Global Quilt,'" says IEEAF Board Chair Don Riley, VP and CIO, University of Maryland. Tyco Telecommunications has also provided a companion 622 Mbps packet over SONET (POS) circuit to the IEEAF.

Geographic Network Affiliates International (GEO), which has played a pivotal role in the Tyco Telecommunications donation to the IEEAF, will be present at iGrid2002 promoting the Global Medical Research Exchange (GMRE) initiative, a worldwide application that exemplifies the collaborative capabilities of the Grid for high bandwidth utilization of IP for medical purposes.

Standards have been planned for 10-Gbit over copper. See

Of course this is for short distances in networks, where copper still holds a big cost advantage over fiber. Latest issue of RF Design magazine also discusses big improvements in DSL for delivery of video.
