  1. VidMid Building Consensus on Middleware for Digital Video Mary Fran Yafchak, maryfran@sura.org Southeastern Universities Research Association

  2. Getting Started Once upon an I2 meeting room in Washington DC…. • Attendees: I2 MW, ViDe (with ANU, Gatech, SURA, SURFNet, UAB, UNC, UT), GSU • Meeting purpose: Compare notes, share project ideas & approaches, decide if there is more to be done

  3. An Initiative is Born • “Vidmid” - Middleware for Digital Video • Goals: • Identify needs (MW for near term DV) • Develop/prioritize usage scenarios • Examine approaches for design/development • Vidmid@internet2.edu • Discussions so far: Naming the group (!), DoD & ENUM, related activities, project scoping

  4. Ken Klingenstein (U-Colorado/I2) Acting Chair Ben Chinowsky (I2) Scribe Egon Verharen (SURFNet) Ivana Belgers (SURFNet) David Pokorney (U-Florida) Mary Trauner (GaTech) Mike Staman (Macon State) Bob Riddle (I2) Michael Gettes (Georgetown) Art Vandenberg (GSU) Ted Hanss (I2) Amy Philipson (ResearchChannel) Keith Hazelton (U-Wisconsin) Pat Jackson (Va Tech) Bob Morgan (U-Washington) Tyler Johnson (UNC) Bob Dixon (OSU) Larry Amiot (ANL/NWU/I2) Renee Frost (I2) Markus Buchhorn (ANU) Mark Poepping (CMU) Dan McCarriar (CMU) Ellen Vaughan (I2) Keith Portis (U-Nebraska) Jill Gemmill (UAB) Mairead Martin (UT) John McNair (UT) David Kuhlman (UT) Phil Galanter (NYU) Mary Fran Yafchak (SURA) Orit Levin (RADVision) Current Members (5/9/01)

  7. And now: DVMiddleware DV middleware - the middleware necessary to support scaleable useful DV usage scenarios • Voice/Video/Data “call” scenarios • Streaming & On-demand scenarios • DV-to-Directory Services scenarios

  8. Scenarios: Directory Services Examples (from Art Vandenberg/GSU): • User can look up person information in a directory. Search interface is simple, “intuitive” and provides contact details. Directory details include attributes specific to supporting videoconference connection (IP address, type of equipment, local time zone info, bandwidth…?). • User’s video conferencing software provides an LDAP interface to the directory information user has set up. The result of a lookup can be used to initiate a conference connection (“click to connect”) and the software can use the configuration details in the directory to negotiate the connection.

  9. Scenarios: Directory Services More examples: • Added feature of user’s directory is that user can index video datasets or other objects that they wish to access during conference. Convenient interface permits them to organize folders, assign sharing access, etc. • User’s directory information is stored in a standard objectClass that enables the information to be discovered easily, promoting interoperability. User is not expected to know details of directory infrastructure. Directory transparently masks any distributed integration required for deployment, performance, or synchronization..

  10. Others scenarios soon.. • Voice/Video “call” scenarios: • Tyler Miller-Johnson, UNC • Data Collaboration scenarios: • Mary Trauner, Georgia Tech • Streaming/VOD scenarios: • Mairead Martin, UT

  11. One Big Happy Mess* • I2 Middleware - Early Harvest/Adopters, MACE (eduPerson, DoDHE, Shibboleth) • Standards makers - ITU, IETF, DMTF, Others? • “Development Communities” - ViDe, TERENA, the I2 Commons, Federal PKI, CREN, Net@EDU PKI & ICS, CSG, Grid Community, Others? *A.K.A “Related Activities & Initiatives”

  12. Interested in More? Today’s Bonus: MFY Working Group Prayer “May we be big enough to be inclusive yet small enough to get things done!” • For all interested - the Vidmid Web site: http://middleware.internet2.edu/video • To join the group, contact any vidmidder • Know someone else who ought to know about vidmid? Pass it along!
