Bob Dixon, Ohio Academic Resources Network (OARnet)_
Internet2 Fall member MeetingOctober 7, 2009
San Antonio, Texas
Schedule of Events
• Introduction of Speakers• Overview of Video Conferencing Interoperability• Description of Yesterday’s Live Demos• Playback of Recordings from the Demos• Presentations by the Speakers

Our Presenters
• Stefan Karapetkov - Polycom• Bill Rippon - IBM Research• Jim Goodyear - LifeSize• Gabe Moulton - Ohio State University• Robbie Noble - Ohio State University

• Web Conferencing– PC and small camera – Collaboration tools such as Skype, Elluminate, WebX.... – 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
*Note there are a few other systems that do not fit into these categories
The Four Levels of Videoconferencing
Telepresence Systems Generalities
• Most telepresence systems are expensive. – Typically $250K and up, per room.
• Some are proprietary or do not use the standard H.323 protocol, and hence are not interoperable with other telepresence systems.– HP, Cisco.
• Some require special or vendor-managed networks. • Some are H.323 standards-based and can become fully
interoperable with one another.– Polycom– Tandberg– LifeSize

Typical Telepresence Systems
• For reasons of brevity, I will illustrate only one typical model of telepresence equipment from each vendor.
– They all have other models also.
• Photos are from the company web sites.

Who Uses Telepresence?• Typically corporate execs, for whom cost is less important.• So far little used in education. A recent poll shows <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, such as classrooms.– Incompatibility with each other, and 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 many of the things that telepresence does, with less cost and complexity.

Videoconferencing Interoperability by Level
11
• Web Conferencing– Very little interoperability, with each other or with industry
standard.– A few now provide interoperability with standard H.323. (Elluminate
VCS, RADVision Scopia Desktop, Vidyo…)– Skype/H.323 gateway being evaluated by Internet2.
• Standard H.323 Videoconferencing– Complete interoperability.
• High-definition Standard H.323 Videoconferencing– Complete Interoperability.
• Telepresence• Few vendors claim interoperability.• Tandberg and Polycom can interoperate thru their MCUs.

Collaboration tools have traditionally had stone walls between each other.

Some collaboration tools have now blasted a hole thru the wall separating them from industry standard video conferencing.And they have begun to penetrate the walls between themselves.
