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.

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.

Just as there is a single content video stream sent

endpoints in a conference, there is a single

endpoints in a conference, there is a single

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.

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.
