    ISDN vs IP
    Old technology: ISDN
    64k per channel
    Expensive in usage
    Limited to low bandwidth (mostly up to 384k)
    Call initialization typically takes 30-60 seconds
    Now and future: IP over Internet
    Unlimited bandwidth
    Flat-fee, no usage costs
    Click and connect, no waiting
    No guarantees, unless you have end-to-end QoS
    All new models support IP,
    Some organisations only allow for ISDN calls

    Multipoint (MCU)
    Conference between two meeting rooms is called point-to-point.
    Does not require any special equipment, one room simply calls the other.
    Simultaneous videoconferencing among three or more remote points is possible by means of a Multipoint Control Unit (MCU). Types of MCU:
    Embedded in a video endpoint
    High-end videoconference systems, such as the LifeSize Team 200 and Room 200 have a build-in MCU.
    Up to 4 or 6 participants.
    Dedicated MCU
    Located in datacenter / server room
    12-48 participants
    Extra functionality such as recording, web-sharing, ...

    Transcoding
    Without transcoding, all participants get video and audio quality of the least powerfull device
    With transcoding, everyone gets the best possible quality
    Video transcoding
    Real-time conversion of video resolution between videoconference participants.
    Audio transcoding
    Real-time conversion of audio codex and quality between videoconference participants.
    Bandwidth transcoding
    Real-time conversion of connection bandwidth between videoconference participants.

    Bandwidthusage
    Some examples
    128 Kbps (400 x 244 pixels) Widescreen FCIF
    384 Kbps (768 x 432 pixels) Cable TV
    512 Kbps (848 x 480 pixels) DVD Resolution
    768 Kbps (1088 x 608 pixels) 2x DVD Resolution
    1.1 Mbps (1280 x 720 pixels) High Definition
    1.7 Mbps (1920 x 1080 pixels) Full HD
    LifeSize automatically adjusts image quality and frame rate based on available bandwith
    Both upstream and downstream are required
    ADSL and Cable type connections usually have low upstream
    A reliable internet connection is key to success!

    Networklatency
    Latency, a synonym for delay, is an expression of how much time it takes for a packet of data to get from one designated point to another
    Type of network links:
    Fibre links: >1ms
    DSL / cable: >10ms
    Satellite links: >500ms
    Latency increases with distance
    Fibre link from Europe to US: 80-150ms
    Speed of light is the limiting factor
  • 3 October, 2009
    High Definition videoconference, deep dive
    Networklatency and videoconferencing
    Try to keep below 150 milliseconds
    Excessive latency increases the chances of people "talking over one another" because they don't realize that the person at the other end has started speaking too. This is less significant in calls with less than 50ms of network latency. It can become very troublesome in calls with more than 150ms.
    Reference table
    < 50ms: humans do not notice any latency
    50-150ms: small noticeable latency, interactive conferencing still very comfortable
    150-250ms: noticeable latency, interactive conferencing possible but need users may need some adaptation (not talk at same time)
    250-400ms: very noticeable latency, interactive conferencing possible is users wait until other have finished talking
    >400ms: interactive conferencing becomes very difficult

  • Select the right monitor size
    Distance to monitor:
    < 2 meter: 37 inch monitor (private offices)
    2-3 meter: 42 inch monitor (very small meeting room)
    4-5 meter: 50 inch monitor (small meeting room)
    5-6 meter: 58 inch monitor (medium meeting room)
    7-8 meter: 65 inch monitor (large boardroom)
    > 8 meter: High definition projector (large boardroom)
    Especially important to read small text and PowerPoint graphics

  • Lights
    Light on participants faces should be between 700-1000lux (vertical light) with less than 200lux variations in the area. Horizontal light should be between 900-1200lux. The area with the monitor screens should have less than 300lux.
    Things to avoid
    Windows in the camera view (direct sunlight)
    Spot lights
    Halogen lighting
    Colors: (ea. Walls)Avoid primary & hard colors (such as: pure red, pure green, pure blue,.....)Avoid very bright colors (such as bright/pure white)
    3 October, 2009
    High Definition videoconference, deep dive
  • Lights (continued)
    Recommendations
    Use fluorescent light with a color temperature of 4000K (Kelvin) (ea. Osram 11)
    Use louvers with reflectors (60x60 - 3 tubes or 120x30 - 2 tubes)Example : ETAP UI44/318 - 60x60 louver normalized yield 0.57 ; 3 light tubes of 26mm/18W/4000K ; color index : 85 ; 4350 lumen luminance
    Use dimmers on all light circuits
    Use at least 3 separated light circuits
    One circuit above the table (direct light for participants)
    One circuit for the background lighting (Back & Side walls)
    One circuit for additional light (ea. near the system cabinet, door entrance,...)
    Cover all windows with blinds or curtains.
    Use a conference table with a 50% reflecting surface (not shining or mirroring). Recommended color is light grey.
    Colors: Use of any color, situated between off-white/beige and light/medium grey. (ea. pastel/pale colors). Recommended : Blue-grey or green-grey color (as they enhances the natural & flesh tones). Most colors mixed with grey are suitable. Avoid too dark colors and those too white. Note: The human eye is not always a good judge for choosing colors; we tend to choose hard colors.

  • Sound / Acoustics
    The room reverberation time should be conform to the RT60 specs and less then 400ms. The ambient noise in the room should be conform to the ISO 35 (NR) curve.
    Things to avoid
    Hard surfaces in microphone pickup ranges , especially windows
    Hard surfaces are reflectors and create echo!!
    ea. whiteboard, wooden walls/cupboards/cabinets,..., brick walls, windows, doors,...
    Noisy (adjacent) rooms and corridors
    Noisy equipment in the room (ie. HVAC - Air-conditioning, printers & fax)
    Air-conditioning in- and outlets in the microphone pickup ranges
    usually from the border of the conference table (nearest to the cabinet) up to the back wall
    3 October, 2009
    High Definition videoconference, deep dive
  • Sound / Acoustics (continued)
    Recommendations
    CEILINGPreferably use a modular T-Grid with acoustic panelsExample : RockfonFibral 567, 25mm (60x60)
    WALL BEHIND CABINETNo acoustic treatment necessary (may be/preferably a hard surface) if the participants are not in eye contact with each other (color is preferably white or pale)
    SIDE WALLS and BACK WALLUse an acoustic absorbing or diffusing tissue. (The sound absorption can be enhanced by also using 10-25mm fiber glass isolation material between the tissue/fabric and the wall.) In case windows need to be covered, use an acoustic curtain. Especially the back wall should be strongly absorbing. Note: mind the colors (see ‘Light’)Example : Cover AplixBlue-Grey ; Ref: Nopal 074 ; absorption factor 0.46 ; acoustic isolation : 6dBExample : Mur de SilenceBlue-Grey ; Ref: M20170 ; absorption factor 0.41 ; acoustic isolation : 4dB
    FLOORUse a (preferably antistatic) carpet. Color is not important, but preferably medium/dark grey
