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.

Desktop Collaboration Tools

Collaboration tools have traditionally had stone walls between each other.

Standard definition and high definition video conferencing work well together.

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.
