This field sets which video codec is used for
conferences' content video streams.
A single content video stream is used for each
conference, and this stream will be sent to all
viewing endpoints. If an endpoint is unable to
receive content video using the codec configured
here, no content channel will be opened to that
endpoint.
This field sets a lower limit on the bandwidth of
the shared content video encoding sent to content
receivers in a conference.
Changing this setting when there are connected
participants causes the MCU to re-assess whether
there should be content video channels to those
endpoints; the MCU will close existing channels
and open new ones as appropriate.
A single content video stream is used for each
conference, and this stream will be sent to all
endpoints receiving the content channel as a
separate video channel. If some endpoints are
only able to receive low bit rate streams (for
instance if they have called into the MCU at a low
call rate), it is sometimes preferable to exclude
those endpoints completely from the content
stream rather than force all viewers to see a
reduced bit rate channel.
If you do not wish to exclude endpoints from
viewing the shared content video channel in a
conference, make sure this is set to <no
minimum>, which is the default setting.
Where an endpoint cannot, for whatever reason,
receive the content channel as an additional video
channel, the MCU can show the content channel
as part of the main video channel. That is, the
participant will see the content as a pane in the
conference layout. This functionality is controlled
by the Display content in normal video channel
setting (see below).
Note that during a call, an endpoint can send a
'flow control message' to the MCU that could
cause the MCU to reduce the bit rate to that
endpoint to below the configured Minimum content
channel bit rate; in this case, the MCU will close
the content channel to that participant. To re-
enable content (which has been disabled in this
way) to this participant, go to the conference's
Participant list and use the content enable
control. For more information about altering a
participant's settings during a conference, refer to
Viewing the conference participant list.
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, or might not support the video format
specified by the Outgoing content video codec setting
