Levels of Videoconferencing

  • Web Conferencing

    • PC and small camera

    • Collaboration tools such as Skype, Elluminate, Dimdim….

    • Fair quality

  • Standard H.323 Video Conferencing

    • Most common type today

    • Good quality

  • High-Definition H.323 Video Conferencing

    • Like HDTV

    • Excellent quality

  • Telepresence

    • HD, plus appearance of being in the same room


Ohio board of regents telepresence grant
Ohio Board of Regents these categoriesTelepresence Grant

  • Grant to OARnet to investigate feasibility of Telepresence among Ohio universities

  • Evaluate all available systems

  • Install 2 pilot systems and MCU


Telepresence systems
Telepresence these categories Systems

  • All currently offered systems were investigated.

  • All were found to be too expensive for most applications. Typically $250K and up.

  • Some are proprietary, and incompatible with all others. HP, Cisco.

  • Some require special or vendor-managed networks. Cisco requires that they certify your network.

  • Some are standards-based and will become interoperable. Polycom, Tandberg, LifeSize.

Who uses telepresence
Who Uses these categoriesTelepresence?

  • Typically corporate executives, for whom cost is no object.

  • Rarely used in education. A recent poll shows fewer than 10 in USA.

  • Reasons for little education use:

    High cost, including purchase, installation and operation.

    Typically not suitable for more than a few people at once.

    May be incompatible with existing video conf equipment.

    Will not dedicate a room to something that is rarely used.

    High bandwidth and network quality required.

    Requires multiple rooms.

  • Standard high-definition video conferencing can do most

    things that telepresence does, at much less cost

    and complexity.


The telepresence kit approach
The these categoriesTelepresence Kit Approach

  • LifeSize Corp was the first to offer low-cost high-definition video conferencing.

  • Now they have offered an inexpensive kit version of Telepresence.

  • $70K, including installation and one year maintenance.

  • Installation by ID Solutions, of Indianapolis

  • OARnet has installed 2 of these as a pilot program, funded by the Board of Regents, as affordable examples for other Ohio universities.


Multipoint telepresence conferences
Multipoint these categoriesTelepresence Conferences

  • Any video conference with more than two locations requires a multipoint control unit.

  • We purchased a Codian 12 port HD MCU.

  • Costs $54K.

  • Supports 4 locations of 3 screens each, or any combination of 12.


Interoperability of levels of videoconferencing
Interoperability of Levels of Videoconferencing these categories

  • Web Conferencing

    • Essentially no interoperability. Collaboranza! 2006

    • https://wiki.internet2.edu/confluence/display/Collaboranza/Home

  • Standard H.323 Video Conferencing

    • Complete interoperability. Megaconference 1999-present

    • http://www.megaconference.org

    • 10th Anniversary Megaconference Nov 6.

  • High-Definition H.323 Video Conferencing

    • Complete interoperability. Gigaconference 2005-2006

    • http://commons.internet2.edu/gigaconference2005

    • http://commons.internet2.edu/gigaconference

      Telepresence Teraconference 2009

    • Little advertised interoperability


Telepresence interoperability
Telepresence these categories Interoperability

  • Only one Telepresence vendor (Teliris) claims interoperability with any other Telepresence vendor.

  • Some Telepresence vendors are natively H.323 compatible (eg - LifeSize, Polycom, Tandberg), making full TP interoperability possible in the future. Full VC interoperability exists now.

  • A few vendors have limited interoperability gateways to non-telepresence VC systems (Cisco, HP).

  • Telepresence systems typically use special dedicated MCUs.

  • Telepresence systems typically do not use gatekeepers; hence they can call only via IP address. No Global Dialing System.

  • Telepresence systems typically use proprietary control systems, to simplify operation. Eg - Crestron, AMX
