Computer Hardware User Manual

Displays a sample still video capture of the

participant.

Click the picture to update it.

Note that conferences that are configured to

require encryption do not show previews. Also

note that previews can be disabled on the

page (refer to Customizing the

user interface).

These controls are only available if the conference

is configured with content enabled, and if the

participant is contributing a main video channel.

This control causes the MCU to

attempt to use the participant's main

video channel as the conference's

content channel source. This will not

be possible if the conference already

has an active content channel source

(either an endpoint's content video

channel or another participant's main

video activated via this control).

This control causes the MCU to stop

attempting to use the participant's

main video channel as the conference's

content channel source. It is necessary

to use this control to switch to using a

different endpoint's primary video

channel or to enable content video

contribution from endpoints.

See Content channel video support for additional

information on H.239 and BFCP.

Although you may use the controls described above to manage one participant at a time, for example to mute that

participant's audio, or to make them important, you may wish to manage all participants at once. The all-participant

controls permit you to do this. Note that you may continue to use the per-participant controls in conjunction with

the all-participant controls. Refer to the table below for details of the controls available:

Makes all participants unimportant

If no participants are currently important, then

this control will be unavailable.

This stops all audio in the conference

(mute).

If no participants are currently muted, the stop

muting controls will be unavailable. If all

participants are currently muted, the mute

controls will be unavailable.
