Customizing a participant's layout view

Displays static sample of video screen in the currently selected layout.

Adds a border thickness to display around the video image.

If the image is displaying off the edges of the participant's screen, add a border until the image displays properly.

Give prominence to one participant over the others.

The number of contributing conference participants determines the size of the large pane.

Displays a single participant.

Displays the four most active participants without seeing them scaled down to a small size if there are lots of other participants.

Used when there are five or more video participants.

Gives equal prominence to up to 20 conference contributors, and is useful for a "roll call" of active participants.

The MCU automatically changes the layout to the 3 x 3 arrangement, and will continue to use this layout for up to 9 participants. With 10 or more participants, the 4 x 4 view is used, and with 17 or more participants the 5 x 4 view will be used. The MCU will then continue to use this layout even if there are more than 20 participants.

Gives prominence to two participants in the center of the view while showing smaller versions of other participants' video streams above and below.

This view is useful for observing a dialog between two participants or for viewing slides and a presenter.

These buttons control whether this participant is permitted to change the layout they see on the endpoint.

These buttons control whether the MCU alters the aspect ratio of the layout sent to the active participant. If the controls are available, you can force the MCU to compose the layout in a 4:3 aspect ratio (Send "normal" format video) or in a 16:9 aspect ratio (Send "widescreen" format video).

The available options for the resolution of transmitted video are controlled by the Transmitted video resolutions setting which can be configured for the whole MCU on the Settings > Conferences page or per configured endpoint (refer to Configuring an H.323 endpoint and/or Configuring a SIP endpoint).

The widescreen setting on the active participant's display tab takes precedence over the preconfigured widescreen setting for the endpoint, which in turn takes precedence over the MCU-wide setting.

These buttons control whether the active participant is allowed to contribute content to the conference.

Content contribution can also be defined in the conference template, the conference, or the endpoint's configuration. The setting on the active participant's display tab takes precedence over the endpoint configuration, which in turn takes precedence over the conference configuration. For more information, see Content per-participant parameters.

These buttons control whether the video sent to the participant is stopped. If the video is stopped, the participant will not see the conference layout, but will still be able to hear the conference and can still contribute audio, video, and content to the conference.

Select which participant receives the focus on this participant's layout.

Depending on the types of participant in the conference (i.e. content channel, endpoint, audio-only participant), you can select from these options:

• Voice-switched: the loudest participant occupies the largest pane in the layout (the default setting)
• Content channel: the content channel occupies the largest pane in the layout
• <participant name>: you select a participant by name and then that participant occupies the largest pane in the layout

This setting will be overridden if a participant is identified as "important" on the Conference Participants List (see Viewing the conference participants list).
