25. 3 October, 2009 High Definition videoconference, deep dive SD vs HD quality Standard Definition (HD) Since 199? Up to 768x432 pixels Up to 30 frames per second High Definition (HD) since approx 2006 Up to 1920x1080 pixels Up to 60 frames per second Allows for eye-contact

26. 3 October, 2009 High Definition videoconference, deep dive 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

27. 3 October, 2009 High Definition videoconference, deep dive 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, ... Popular brands:

28. 3 October, 2009 High Definition videoconference, deep dive 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.

29. 3 October, 2009 High Definition videoconference, deep dive 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!

30. 3 October, 2009 High Definition videoconference, deep dive 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

31. 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

36. Table and camera position (continued) Muchbetter 3 October, 2009 High Definition videoconference, deep dive

37. 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 3 October, 2009 High Definition videoconference, deep dive

38. 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

39. 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. 3 October, 2009 High Definition videoconference, deep dive

40. 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

41. 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 3 October, 2009 High Definition videoconference, deep dive
