VFO-4200 Video
Firewall Options
The MCU has 2 Ethernet ports - A & B. Port B
is disabled, by default, on the base MCU and
IP VCR. The activation of the video firewall option
feature allows Port B to be enabled. In a video firewall
deployment one of the ports is connected to the local network (typically
Port A) and the other (typically Port B) is connected to the Internet.
This is because Port B cannot use DHCP. This allows the MCU to host
conferences with a mix of participants from the internal and external
networks. This does not compromise your network security because the MCU
will never route packets between the two ports, not even media packets.You
can purchase your unit with the feature already activated
or add the option later.
Web Conferencing Options - WCO
- WCO-4205 Web Conferencing Option for the MCU-4205
- WCO-4210 Web Conferencing Option for the MCU-4210
- WCO-4215 Web Conferencing Option for the MCU-4215
- WCO-4220 Web Conferencing Option for the MCU-4220
With the Web Conferencing Option you can add
data, such as slides, chat and annotations to standard video and voice
streaming, giving each participant an interactive experience regardless of
how they connect.
The Codian MCU 4200 series supports the ITU H.239 protocol. This protocol
allows H.323 endpoints to contribute or receive an additional video channel
when communicating to the MCU. This additional video channel is typically
used for a low-motion, high resolution stream such as a slide-based
presentation. Web conferencing. In addition to
communicating with H.323 endpoints using the H.239 protocol for contributing
or receiving this content channel, the MCU 4200 series also provides the
facility for streaming the content channel to users’ desktops. As part of
content channel streaming, video markup may be added to the content video
stream, and text chat messages may be sent between participants. These
features require the web conferencing option
feature key.
H.239 availability for ad hoc conferences The H.239 (content channel)
is available in scheduled conferences
and it is also available in ad hoc conferences,
if this option is enabled for the unit. H.239 streaming change With version
1.3(x) software, an optional WCO feature key was required to enable
streaming viewers to view the content channel. Without the feature key, the
content channel was unavailable for streaming viewers. With this release
(version 1.4 software), on an MCU without the WCO feature key, streaming
viewers will see the content channel as a pane in the main video window. The
behavior for an MCU with the WCO has not changed.
You can configure the
MCU to share data with a conference using H.239 and VNC. H.239 is enabled
box-wide by default but you can also enable or disable it on a per
conference basis. The H.239 channel is in addition to the main video
channel. The MCU has several methods of displaying data within a conference:
Via the H.239 channel to endpoints In the standard video channel
Streaming to a web browser.
Third party free software VNC can be used to
share PC data in a conference so that participants
with endpoints that do not support H.239 can still contribute data. On the
computer that you intend to use, download the free edition of VNC from
http://www.realvnc.com/download.html. The MCU calls
the VNC computer participant into the conference and the PC desktop is
shared in the conference.
High Resolution Options - HRO
- HRO-4205 High Resolution Option (4CIF) for the MCU-4205
- HRO-4210 High Resolution Option (4CIF) for the MCU-4210
- HRO-4215 High Resolution Option (4CIF) for the MCU-4215
- HRO-4220 High Resolution Option (4CIF) for the MCU-4220
With the High Resolution Options, the MCU supports
enhanced resolutions from 4CIF up to 720p HD, allowing multiple sites to be
viewed simultaneously with no loss of clarity — you can clearly see all
participants and content at the same time.
Every port on the MCU supports: a. Any Codec
(H.261, H.263, H.264) b. Any Speed (up to 4MB) c. Any Resolution
(QCIF,CIF,4CIF,VGA,SVGA,XVGA)
The ability to send video in widescreen format is governed by the
presence of the high resolution feature key (HRO). If the MCU has not been
configured with this feature key, these controls will not be available.
Send "widescreen" format video to a participant
- means that the video is intended to be displayed on a screen whose
dimensions (width and height) are in the ratio 16:9.
Send "normal" format video to a participant -
this means that the video is intended to be displayed on a screen whose
dimensions (width and height) are in the ratio 4:3.
Enhanced resolution support - the
current software release includes support for 720p (1280 x 720)
screen resolution with H263+.
