8 - 2:30:

Welcoming remarks from ViDe (Jill Gemmill, University of Alabama at Birmingham)

Using IP Video for Virtual Presence During Laparoscopic Surgery (Jerome Johnson, department of surgery, Ohio State University)

After a brief Powerpoint presentation, we will connect to a minimally invasive operating room at University Hospital, Ohio State University, Columbus, OH, where we will interact with the surgical team during a laparoscopic operation. We will demonstrate the various tools we have adapted to IP video and discuss the use of this technology for distant collaboration and consultation in the surgical field. We will also compare and contrast quality of signal at various bandwidths and discuss minimal standards for surgical collaboration.

Broadband Visual Communication for Learning Communities (Martin Brooks National Research Council of Canada)

Work with high school students, high school teachers, and advanced violin students has provided us with some valuable insights into the unique and advantageous attributes of broadband visual communication. This talk will briefly review our experience and describe new knowledge that we have gained.

Louisiana's Interactive & Collaboritive Research Network (Kenneth Tanner, LSU Health Sciences Center - Shreveport)

Presentation on the creation and ongoing development of the interactive and collaborative research network deployed in Louisiana. The network consist of 12 higher ed research institutions with Louisiana all using H.323 to interact and collaborate. Internet 2 is the backbone used for the H.323 transport so the institutions not only interact amongst themselves but also to other Internet 2 institutions. We have also incorporated a management system and a data collaboration tool.

Ethnographic Filmaking/"Guerilla Filmaking in Anthropology" (Rosie O'Beirne, University of Alabama at Birmingham Center for Urban Affairs

Innovative partnership between the Anthropology and Art departments that teaches students to produce a digital video community education site called "The Street," hosted at the McWane Center Science Museum; an on-site kiosk will show student films to demonstrate what can be taught in a single semester couse.

Videoconferencing as an Enabling Tool for Project Actvities: a Case Study of "Imagining the Future" Project (Dr. Amela Sadagic, Advanced Network & Services)

"Imagining the Future" is a three-years umbrella project that invites students and educators to explore how young people learn when they have access to advanced technologies, including high-performance broadband networks (primarily Internet2 but also wireless networks), large-scale public digital resources, rich digital media, and powerful platforms for creating educational products. More specifically, this projects provides a diverse set of activities and tools to facilitate the process of imagining and prototyping students' vision of future learning systems. This talk will detail our experiences in using H.323 videoconferencing system. We will provide our insights and lessons learned on how we coupled this system with a set of creative activities that ranged from multipoint connections to support expert presentations given by leading scientists, over smaller group activities, to one-to-one sessions with teachers and student teams. The overview of other supportive environments and tools that we used in conjunction with videoconferencing tools will be also described. "Imagining the Future" project is closely related to our efforts and work in Internet2 K-20 initiative.

Thursday 4/25, 8 AM until 3:30 PM

Morning session: Emerging & Related Technologies

8 - 11:30:

VidMid-VC: Middleware for Video Conferencing Services (Egon Verharen, Innovation Manager, SURFnet; VidMid-VC Chair) (TBD)

Video has long been seen as a killer application, especially on advanced networks, for both its conferencing and its streaming modes. Deployments have been limited and primitive in large part due to the lack of a middleware infrastructure to make the application usage easily accessible to typical users. The solutions to the above will attempt to leverage federated administration. Federated administration describes the emerging model where autonomous systems or enterprises form communities of interest to exchange management data. In higher education, campuses will group together into federations to share resources and build collaborative environments.

The Vidmid working group, a partnership of Internet2 and ViDe, has been working on these issues and recently has made significant progress in defining requirements and developing architectural alternatives. This session will include a report from the videoconferencing subgroup on authentication and authorization flows, directory and objectclass issues, and naming and resource discovery.

ViDe Developments for Video on Demand (Mairead Martin, Director of Advanced Internet Techologies, University of Tennessee; VidMid-VOD Chair; ViDe MPEG-4 Chair and Video Access Co-Chair) (TBD)

This presentation will present an overview of ViDe work being conducted on video-on-demand. There are currently three ViDe video-on-demand working groups - Video Access, MPEG-4, and VidMid Video-on-Demand. The latter is a collaboration with the Internet2 Middleware Initiative. Digital rights management, metadata application profiles, and MPEG-4 applications are some of the issues and work currently underway for these working groups. The presentation will describe these efforts in detail, and offer participants the opportunity to become actively engaged in this work.

Low Cost Satellite Internet Access for Distance Learning in Rural Areas (Dr. Bob Dixon, Chief Research Engineer, Ohio State University and OARNet)

The American Distance Education Consortium is deploying low-cost satellite internet access systems at minority colleges throughout the country. About 50 are in operation so far, used predominently for web-based instruction. Video conferencing applications are being added as the speed and quality of the connectivity improves. A portable trailer-mounted version of the system is being developed for use in circuit-riding distance learning, and at special events such as fairs and conferences.

Internet2 QoS and Video: Sharing Responsibility to Overcome Congestion-Related Performance Problems (Ben Teitelbaum, Senior Engineer, Internet2, & Dr. Amela Sadagic, Advanced Network & Services)

Since its inception, one of the primary technical objectives of Internet2 has been to engineer scalable, interoperable, and administrable interdomain Quality of Service (QoS) to support an evolving set of new advanced networked applications. Facing a set of intractable deployment obstacles, the Internet2 QoS program has shifted its focus from building an EF-based, virtual circuit service, dubbed the "QBone Premium Service", to designing and deploying non-elevated services that deploy incrementally, with no policing.

This talk will survey the inherent QoS requirements of videoconferencing, together with the QoS requirements of current H.323 internet videoconferencing systems. We will also discuss the enormous challenges facing elevated forms of QoS like the QBone Premium Service and look ahead to non-elevated services that can support latency-sensitive application like videoconferencing. Engineering advanced applications and advanced network infrastructure in concert requires careful consideration of where to add complexity. We will discuss these engineering trade-offs in the context of QoS and internet videoconferencing.
