The following LifeSize video
conferencing systems are recommended:
1. for point-to-point video conferencing:
- LifeSize Express 220 full HD point to
point system.
2. for multipoint video conferencing:
- LifeSize Team 220 full HD video
conferencing system with built-in 4-party MCU.
- LifeSize Room 220 full HD video conferencing
system with built-in 8-party MCU.
The LifeSize video conferencing
systems can be used with any full HD LED TVs, LCD TVs or LCD
projectors. For best video quality
results, 1080p30 full HD LED TVs, LCD TVs and LCD projectors are
recommended. The LCD projectors
shall have brightness of 3000 ANSI lumens and above. Either 1 or 2 displays can be used. When connected, users will see the far
end video and local video on the displays.
If 1 display is used, the far end video and local video will be
displayed as either side-by-side videos or picture-in-picture videos. If 2 displays are used, the far end video
and local video will be shown on the separate displays. As LifeSize is a full HD video
conferencing system, videos displayed are in 16:9 aspect ratio.
In addition to
the real time video conferencing session, users are able to connect their
PC to the LifeSize video conferencing system to start a presentation.
When the
presentation starts, the LifeSize video conference systems will use the H.239
dual video sending and receiving feature to allow local and far end users
to view both video and presentation slides simultaneously. The PC presentation will be in 1080p30
full HD resolution as well.
If 1 display is
used, the following display options are possible:
  
  
If 2 displays are
used, the video and PC presentation will be displayed separately on the 2
displays.
Good audio pickup coverage is usually a primary concern of a
video conferencing system. For a
meeting room of more than 10 people, the meeting table could be long
rectangular or U-shape. It is not
sufficient to use the default microphones of the video conferencing
system. 3rd party
microphone systems with echo cancellation are required to be integrated
with the video conferencing system.
The microphone systems recommended
are:
1. ClearOne InterACT AT
It has 3 InterACT microphone pods
(each with 3 microphone elements, 9 microphones in total).
2. ClearOne InterACT Pro
It can support up to 16 desktop
boundary microphones and these microphones can be placed any where on the
table. This arrangement is
particularly good for U-shape meeting table.
  
3. ClearOne SR1212 with desktop boundary
microphones.
It can support as many desktop
boundary microphones as possible and these microphone can be placed any
where on the table. Particularly
good for a very long rectangular or a very large U-shape meeting
table. Up to 100 desktop boundary
microphones can be supported.
By default, all LifeSize video
conferencing systems run well on any TCP-IP network (leased line or
broadband internet access) using H.323 or SIP protocol.
For connection using H.320 protocol or
ISDN network, the optional LifeSize Networker can be used. It supports up to 4 ISDN BRI lines or 1
ISDN PRI line.
The LifeSize video conferencing
systems are fully ITU-T H.323, SIP and H.320 compliance and compatible with
any systems from other manufacturers.
With the optional LifeSize Video Center,
the entire video conference meetings can be streamed live and/or recorded
just by pressing a button on the handheld remote control unit. The recorded videos can be playback using
a PC, Mac computers and iPhone/iPad/iPod whenever required.
