Maintenance Manual

Display
content in
normal
video
channel
Sets whether the MCU will render content
channel data in endpoints' main video
channels.
If there is an active content channel for a conference, it
may be that the MCU is unable to open a content
channel to a particular endpoint. For instance, that
endpoint may have no content capability. Passthrough
content cannot be sent in the main video channel. The
message Content source (main video) - No effect in
passthrough mode is displayed.
In these cases, if this option is set to Enabled, the MCU
will display the content channel video within a pane of
the currently selected conference layout. In these
cases, you might also want to enable the Automatically
make content channel important option in the Settings
> Conferences page which will make the content
channel important at the same time.
Note that SIP endpoints receive content from the MCU
in the normal video channel (rather than in a separate
channel). For this reason, this option must be enabled to
allow SIP participants to see content.
Video fast
update
request
filtering
If this option is Enabled, the MCU will
ignore fast update requests for a
conference's content video channel
received from endpoints whose
connections are experiencing problems.
When this mode is active, it can prevent a large number
of keyframes being sent in the shared content video
encoding in response to fast update requests from a
single endpoint. A high number of keyframes may
reduce the video quality of the content channel for all
conference participants, including those with good
connections to the MCU.
Web
viewing
applet
bandwidth
Sets the bandwidth of the content channel
video stream sent to streaming viewers.
This option is only available if the MCU web
conferencing (WCO) feature key is present.
Just as there is a single content video stream sent to all
content-capable video conferencing endpoints in a
conference, there is a single content channel video
stream sent to all streaming viewers.
This option allows the bandwidth of the streamed
content channel video to be set. While in general a
higher value means a greater frame rate (and thus better
video quality), it is important to not set this value too
high (i.e. higher than the available TCP network
bandwidth between the MCU and viewers' machines) to
avoid degradation resulting from lost data.
Markup of
content
channel
video
If Enabled, people viewing the content
channel stream via a web browser will be
able to add markup to that video stream
such as graphics and text. This markup will
then be visible to all content channel
viewers, both those viewing via streaming
and those connected via
videoconferencing endpoints.
This option is only available if the MCU web
conferencing (WCO) feature key is present.
Changing this setting has an immediate effect:
■ if changed to Disabled, it will not be possible for
existing viewers to complete markup currently in
progress
■ if changed to Enabled, existing streaming
viewers will gain the ability to add markup
