International Events
As an extension to our testbed teaching experiments, we undertook numerous demonstrations to institutions around the world. Demonstrations to most parts of the world were over Internet connections of 2Mbps or less, and with significant delay. In these situations, slide presentations using videoconferencing applications were the most effective.
In some demonstrations, Internet2 quality bandwidth was available. The remote site could access our resources, such as RSV images, interactively, though only in mono-viewing, not stereo. However, true multi-site collaboration was not available. Screen- sharing applications, such as vnc, supported collaboration but interaction was slow.
Some sites had stereo-viewing capability, enhancing the viewing experience. Others, such as the KISTI and MEDRIC sites in Korea, had high-definition videoconferencing capability, thus providing an extremely strong sense of presence between our laboratory and theirs. However, only those sites, such as NOSM and a few others, who had installed the RSV client and had multicast capability, experienced the collaborative interaction that our application and content was able to provide.
Hear Dr. Young Sung Lee from MEDRIC in South Korea discuss the value of these collaborative events.
