It's an opportune time for up-and-coming conferencing service providers to deploy collaboration solutions based on VoIP architectures. Early adopters amongst the Conferencing Service Providers (CSPs) have demonstrated the benefits and cost-efficiencies of these technologies in large hosted conferencing deployments. Now is the time for smaller or emerging market CSPs still operating legacy TDM audio bridges to embrace IP-based audio conferencing platforms, and capture your fair share of the growing hosted collaboration market opportunity.

What Attendees will learn:
* Understand the trends and key requirements for business customers using hosted conferencing services, and how traditional TDM audio bridges are not keeping up.
* Learn how IP-based conferencing platforms not only deliver cost-efficiencies in hosted conferencing services, but they also offer the flexibility to seamlessly integrate into collaboration processes and communication behaviours of your target markets.
* Understand the equipment and features required in entry-level systems to get you started, with the scalability to grow, or add video and web collaboration capabilities.

  • For Visual Communications, Quality is Key
  • QoS costs…
  • So why not use the Internet?!
  • Poll question: What are the main challenges for using the Internet for real-time video?
    Packet Loss
    Insufficient Bandwidth
    Delay
    Finding who/how to call
    Etiquette peripherals on the other side
  • The Challenges of the Public Internet
  • Video flows in pipes…
    Output
    Input
  • If the pipes don’t have enough capacity…
    Output
    Input
    Congestion
    Delay
    Packet Loss
  • Typical IP Network Impairments
    Packet Loss
    Corruption
    Congestion
    Corrupted packet rejection
    Multi-path
    Collisions
    Dropped by router / switch
  • Typical IP Network Impairments
    Jitter
    TX
    RX
    T
    T+2Δ
    T+4Δ
    T+Δ
  • Packet loss significantly reduces quality!
  • Too many users
    Too many tasks
    Home Worker/Road Warrior
    There is no such thing as enoughbandwidth…
  • Productivity is the name of the game
    By EOY 2011 ~75% of US workforce will require mobile capabilities
    WW mobile workers increase from 759M in 2006 to >1Bn by 2011
  • High Quality of Experience Check-list
    Low delay
    No artifacts
    The right bandwidth
    High definition resolution
    High quality codec
    High quality peripherals
  • Making Real-Time Video Work
    Technologies and Solutions
  • Effective Bandwidth Estimation & Adaptation
  • How does it work?
    Output
    Input
    Packets
    Delay!
  • Look for congestion and solve it before packets are dropped
  • How does it work?
    Monitors delay for “trends”
    Reacts accordingly
    Converges quickly to the effective bandwidth
  • Key Elements for Bandwidth Estimation
    Delay based vs. Packet loss based
    Faster convergence time
    Better evaluation of effective bandwidth
    adapt before artifacts appear!
    adapt quicklyto changes!
    utilize mostof the bandwidth
  • Quality of Experience
    NetSense vs. Competition
    Latency
    * G.1070 score - The higher the score, the better the quality
    * The lower the latency, the better the quality
  • Scalable Video Coding – The Promise
    “One ring to rule them all”The Lord of the Rings, J.R.R Tolkein
    Generate a single video stream that can serve multiple users
  • Scalability of Video - Modalities
    Temporal - Change of frame rate (e.g 30 FPS, 15 FPS)
    Spatial - Change of resolution (e.g720p, 480p, CIF)
    Fidelity / SNR - Change of quality (e.g1 Mbps, 512 kbps)
  • The Hidden Promise of SVC
    H.264
  • The layered structure of SVC introduces higher level of error resilience
    The Hidden Promise of SVC
    H.264 SVC
  • The Hidden Promise of SVC
    H.264 SVC
    The layered structure of SVC allows for Unequal Error Protection (UEP)
  • Protect SVC base layer
    Dynamic FEC strength
    FEC-XOR, FEC-RS
    Reliable Transmission - FEC
  • SVC is Not Just a Single Cake
    Signaling
    SVC
    Transport
    Unequal Error Protection
  • Handling IP Network Impairments
    Packet Loss - Corruption
    SVC + FEC
    Packet Loss - Congestion
    NetSense
    Jitter, Out of Order
    AJB
  • RADVISION’s Solution
    SVC + FEC
    5% packet loss
    5% packet loss

    Inter-Enterprise Communication (SIP, over public Internet)
    Vertical-specific applications – mobile and fixed
