Advanced networks are making it possible for libraries to expand access and outreach opportunities in never-before imagined ways.

Advanced Video Technologies

Advanced video technologies and collaborative tools are allowing organizations on the MAGPI and Internet2 networks to communicate in new and exciting ways.

Access Grid® is a suite of collaboration technologies that enable large scale (wall or room sized) group collaboration including live video, audio, and data sharing. The Access Grid® is an ensemble of resources including multimedia large-format displays, presentation and interactive environments, and interfaces to Grid middleware and to visualization environments. These resources are used to support group-to-group interactions across the Grid.

Microsoft Research's Conference XP software allows for distributed interactive collaboration spaces using a virtual venue. It integrates recent advances in high-performance audio, video, and network technologies to seamlessly connect multiple, distant participants in a rich, immersive environment for distance conferencing, instruction, and collaboration. ConferenceXP provides an extensible foundation for interactive collaborative environments and serves as a research platform for designing and implementing distance conferencing and learning applications. Currently, it is being used for multi-institutional instruction, distance learning, and advanced research collaboration. MAGPI runs a Conference XP test node that is available to MAGPI Members.

The Digital Video Transport System (DVTS) is a simple and inexpensive method of transmitting high-quality video and audio over the Internet. DVTS uses 30 Mbps uncompressed video to provide high-quality images with low latency. DVTS can also be used in multicast mode to allow three or more sites to participate in a single conference. More broadly, DVTS is a step toward a world in which you will be able to tune your computer to a series of educational channels the same way you tune your television to satellite channels—send and receive high-quality video across the Internet with the same ease as sending and receiving email - - and do all this without any significant capital expenditure.  DVTS-based telemicroscopy is used for real time clinical case consultation between pathologists at the three Philadelphia hospitals that make up the University of Pennsylvania Health System. The Office of Cultural Affairs at Montgomery County Community College used DVTS to conduct dance critiques between dancers in Pennsylvania and choreographers in Japan.

Digital Library/Video Repositories

Organizations on the MAGPI and Internet2 networks can take advantage of expansive networking infrastructure in order to facilitate digitization projects or access large quantities of data. The Library Congress is collaborating with the Internet2 community to leverage its advanced network infrastructure to facilitate wide-scale digital preservation projects and to enhance the development of an Internet-based database of U.S. newspapers. C-SPAN has digitized its entire holdings from 1998 to the present and allows educators and researchers to access this collection via the Internet2 Network. The video library is searchable using a extensive number of fields such as topic, speaker, organization, committee, keywords and has an optimized word searching tool that includes abstracts and closed captioning text. The University of Pennsylvania has made over 12,000 images from various collections of rare books, manuscripts, papyri, photographs and sheet music are available over the network through their SCETI Project.  

InCommon

The mission of the InCommon Federation is to create and support a common framework for trustworthy shared management of access to on-line resources in support of education and research in the United States. To achieve its mission, InCommon will facilitate development of a community-based common trust fabric sufficient to enable participants to make appropriate decisions about the release of identity information and the control of access to protected online resources. InCommon is intended to enable production-level end-user access to a wide variety of protected resources. For more information see http://www.incommonfederation.org/.

Interactive Videoconferencing

Videoconferencing allows people in geographically distributed locations to see and hear each other and collaborate in real-time. Increasingly, videoconferencing is becoming part of the standard set of tools used by teachers, students, faculty, staff, librarians and researchers to enhance communication, training, and instruction. Public and cultural organizations are using videoconferencing to expand their outreach opportunities and reach audiences beyond their geographic proximity through virtual lectures and field trips. MAGPI supports the use of videoconferencing within our member community through interactive educational programming, training and technical support.

MAGPI Members can facilitate multisite videconferences through MAGPI’s Internet2 Commons subscription. This service provides a large-scale deployment of tools for one-to-one, one-to-group, and group-to-group collaborations enabling the Internet2 research and education community to hold distributed working groups, classes, meetings, and events. As of July 1, 2009, this MCU service available to our members for $15/connecting site/ hour for your events. Through this service offering, MAGPI members can conduct multi-site videoconference events, as well as webstream those events live and archive them.

Multicast

Multicast is a set of technologies that enables efficient delivery of data to many locations on a network. In today’s Internet, the dominant model of communication is “unicast”—the data source must create a separate copy of the data for each recipient. When there are many recipients, and when large amounts of data (e.g. streaming video) are being sent, unicast becomes prohibitively wasteful of bandwidth. The key idea behind multicast is to create each recipient's copy of each message at a point as close to that recipient as possible, thus minimizing the bandwidth consumed. In July 2007, MAGPI worked with the Friends of Live Earth Global Screens Program to send out a 30 mbps webstream of the 24-hour Live Earth Concert to campuses and organizations on the MAGPI and Internet2 networks, as well as other research and education networks worldwide. Northwestern University and Video Furnace, in collaboration with C-SPAN and Internet2, make live, high-quality C-SPAN and C-SPAN2 broadcasts [PDF] available 24 hours a day to anyone with an Internet2 network connection that is multicast capable.
