Transcript

  • 1. Interoperability And Its Impact On The Market
    Sean Lessman
    Director of Engineering, US Public Sector Telepresence
    March 8, 2011
  • 2. Interoperability
    capable of being used or operated reciprocally
  • 3. “Standards Based”
    based upon an agreed upon set of guidelines typically put forth by a recognized authority (i.e. standards bodies)
  • 4. Interoperability vs Standards Based
    Proprietary methods have never really been successful in videoconferencing
    Non interoperability always costs more money in the long run
    Just when you think you have it figured out…
  • 5. Timelines
    1996 – H.263
    1996 – SIP
    2000 – Transition to IP (H.323)
    2002 – SIP gains some steam
    2003 – H.264
    2005 – Firewall traversal
    2005 – High Definition
    2006 – Multi-codec Systems (Telepresence)
    2007 – H.323/SIP Hybrid environments
    2008 – SVC
    2009 – Multivendor/Multi-codec interoperability begins
  • 6. Telepresence (Multi-Codec) Interoperability
    Several flavors on the market
    Cisco developed ‘TIP’  open source
    There needs to be more done
    CLUE (ControLling mUltiple streams for tElepresence)
    What screen to put the video?
    Angle of view?
    How to handle overlap of multiple screens
    Audio
    Multipoint considerations
    Aspect ratios, framerates, resolution, video encoding
    Presentations and content sharing
    …more
  • 7. Multi-codec Systems
  • 8. Business to Business
    Playing well with others
    Microsoft OCS
    IBM Sametime
    Firewalls
    Up to date firewall support of video
    Firewall traversal (H.323 and SIP)
    Directory Services
    How do you find someone?
    How to make it easy to connect?
    The dial plan problem
  • 9. Business to Consumer
    Financials and Healthcare
    Playing well with others
    Skype
    Facetime
    Home telepresence
    Apple sold 30M video enabled devices in Q410
    Firewall traversal
    Directory systems play a large part
    Social networking systems?
    The dial plan problem
  • 10. Mobility Challenges
    Unlimited Plans going away
    Better international plans
    Different platforms
    OS war in the mobile market
    Android fragmentation
    Networks, bandwidth, peering points
    Packet Loss
  • 11. Outside The Enterprise
    IP
    Home office
  • 12. Challenges
    Multi-codec interoperability
    B2B and B2C must connect in a scalable way
    Mobility requires adaptiveness to non-guaranteed networks
    We need to make this easier
  • 13. Thank you!
