  13. 13. What is H.323-Based Videoconferencing?  A real-time, two-way exchange of information between two or more geographically disperse locations using audio, video and sometimes data  International Telecommunications Union ratifies standards for communications technologies, such as H.323  H.323 is an umbrella standard that encompasses standards for – Audio • G.711, G.722, G.722.1, G.723.1, G.728, G.729 – Video • H.261, H.263, H.264 – Data • H.239 – Others: Call Control, Directories (H.350) TRACC Transportation Research and Analysis Computing Center
  14. 14. Different Technologies  Standards-based: – H.320: videoconferencing on ISDN lines (Legacy) – H.323: videoconferencing over packet-based networks i.e. IP TRACC Transportation Research and Analysis Computing Center
  15. 15. Video Algorithms  H.261 is the oldest of the standards – Most H.323 and H.320 endpoints can handle this algorithm  H.263 is newer – Most newer H.323 and H.320 endpoints can use this algorithm  H.264 is the newest – Only the newest H.323 endpoints use this algorithm  High Definition – Typically compressed using H.264 – Typically at 1 to 2 Mbps or higher TRACC Transportation Research and Analysis Computing Center

  39. 39. Telepresence With thanks to Robert Dixon, OARnet and Ohio State University for contributions of slides from his investigations on Telepresence In cooperation with the U.S. Department of Transportation, Northern Illinois University and the University of Illinois
  40. 40. Telepresence  Telepresence is a specialized version of video conferencing, in which great efforts are made to create the illusion of a face-to-face meeting.  These efforts include specially-designed video and audio equipment, furniture and room layout.  Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance that they were present, or to have an effect, at a location other than their true location.  Primarily used by large corporations where eye contact and body language is important for negotiations and where initial and ongoing system cost is not important  Usually externally managed system and network although “unbundled” systems are available TRACC Transportation Research and Analysis Computing Center
  41. 41. General Appearance  Dedicated room. Wall paint, carpet, lights etc all identical in all rooms.  Occupies room completely, awkward for other uses.  Two or more large screens  Very wide desk  Furniture cannot be moved  Cameras and microphones are fixed in position. Everyone looks life size. TRACC Transportation Research and Analysis Computing Center
  42. 42. Traditional Telepresence Systems  Turn key systems that were investigated were found to be too expensive for most applications. Typically $250K and up.  Some are proprietary, and incompatible with all others.  Some require dedicated and vendor-managed networks.  Cisco requires that you connect to a specific network (National Lambda Rail), and will not publicly answer questions about why.  A recent poll shows that Telepresence is rare among education and research organizations. Fewer than 10 in the USA. TRACC Transportation Research and Analysis Computing Center
  43. 43. The Companies  Teliris and Telanetix are the oldest companies in the business. Telepresence is the only thing they do. Teliris provides ONLY managed systems  Teliris claims that telepresence cannot be achieved unless it is totally managed by a vendor.  Hewlett Packard and Cisco provide the highest-end and highest- cost systems.  The HP Halo system is provided ONLY as managed system  Polycom, Tandberg and LifeSize are all traditional video conferencing companies, who have leveraged their existing products to make telepresence systems.  Tandberg has a relatively new system which is based on traditional videoconferencing technology. They have several sizes with the T3 being the largest and utilizes their C90 HD codec. TRACC Transportation Research and Analysis Computing Center
  44. 44. Tandberg T3 Telepresence Room  Tandberg PR- Not my words – Exclusive Scandinavian design Ultimate quality in video and audio — high definition up to 1080p with three large 65" full HD displays – Highly immersive — sets a new standard in ergonomics delivering a revolutionary user experience – Excellent eye contact and ideal screen height – Appealing, intuitive user interface – Telepresence T3 includes system, table, three personal touch collaboration screens and lighting – An immersive room package adds premium wood walls, TANDBERG Blue nordic-sky-inspired light package, chairs and a bench for additional seating – Collaboration screens deliver UXGA* high-definition presentation capabilities built right into the table – Unmatched connectivity and network flexibility TRACC Transportation Research and Analysis Computing Center

  49. 49. The Telepresence Kit Approach  LifeSize Corp was the first to offer low-cost high- definition (HD) video conferencing.  Now they have offered an inexpensive kit version of Telepresence.  $70K, including installation and one year maintenance.  Installation by ID Solutions  OARnet has installed 2 of these as a pilot program. TRACC Transportation Research and Analysis Computing Center
  50. 50. The LifeSize Telepresence System • Four cameras • Three 60-inch monitors for video • One 50-inch monitor for slides, etc. • Touch-screen control system TRACC Transportation Research and Analysis Computing Center 50
  51. 51. Multipoint Telepresence Conferences  Any video conference with more than two participants requires a multipoint control unit.  OARnet purchased a Codian 12 port HD MCU,  Costs $54K.  Supports 4 locations of 3 screens each, or any combination of 12.
