The solution consist of the following
video conferencing components:
1. 1 unit of Radvision Scopia Elite 5115
1080p30 full HD MCU with capacity of 15-port
2. 15 units of LifeSize Express 220
1080p30 full HD point to point video conference systems at the HQ and the
14 branches.
The LifeSize Express 220 video
conferencing systems will be installed at HQ and each branch; and connected
to LED TVs, LCD TVs or LCD projectors.
Either 1 or 2 displays can be used per location. For best video conferencing quality,
1080p30 full HD LED TVs, LCD TVs and LCD projectors are recommended. The LCD projectors shall have brightness
of 3000 ANSI lumens and above.
The Radvision Scopia Elite 5115
1080p30 full HD MCU can be installed at the data center of HQ or hosted at
public data center. The MCU will
have a gatekeeper to allow:
-
a simplified dial plan using E.164 numbers and
-
video conferencing systems at each location to dial into the room
directly.
The LifeSize Express 220 video conferencing
systems and the Radvision Scopia Elite 5230 1080p30 full HD MCU will be
connected using IP network and H.323 protocol.
Video conferencing systems from the
ISDN network using H.320 protocol are able to join the multipoint meeting
as well via the Radvision ISDN Gateway.
Bandwidth requirement for each
location are as follows:

WCIF video resolution @ 30fps: 4.0Mbps 256kbps 256kbps
During a multipoint session, all
locations will see each other on a same screen using the continuous
presence video layouts feature of the MCU.
In addition,
users at any locations are able to connect their PC to the LifeSize
Express220 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 far end users to view both video and
presentation slides simultaneously.
H.239 dual video send and receive feature is also supported by the
Radvision Scopia Elite 5115 MCU.
The MCU is able
to support 1 multipoint session with up to 15 video conferencing systems
together; or multiple sessions concurrently with the total number of
endpoints not exceeding the capacity of the MCU.
For secure
connection, the embedded AES encryption of the LifeSize video conferencing
system and Radvision MCU can be used.
The Radvision Scopia Elite 5115 MCU is also equipped with
web conference capability. This
capability allows PC and Mac computer users with a webcam to join the
multipoint video conferencing sessions using web browser. No licensed H.323 software clients are
required. These PC users will see
the same continuous presence video layouts and able to present/receive PC
presentation in H.239 dual video mode as well.
The Radvision Scopia Elite 5115 MCU is also equipped with
recording capability. This
capability allows the multipoint video conferencing sessions to be recorded
for archive or on-demand viewing later.
If the Radvision Scopia Elite 5115 MCU and its gatekeeper
are deployed in the LAN together with the other LifeSize Express220 video
conferencing systems, and need to invite some H.323 IP video conferencing
systems from outside the LAN, the Radvision PathFinder firewall traversal
will be required.
The LifeSize video conferencing
systems and Radvision Scopia Elite 5115 MCU are fully ITU-T H.323, SIP and
H.320 compliance and compatible with systems from other manufacturers.
The Radvision Scopia Elite 5115 MCU is
able to host and bridge connectivity for various telepresence systems as
well.
