Enabling And Disabling Video Clarity™ (Avc-Based Conferences); Muting All Participants Except The Lecturer (Avc-Based Cp Conferences) - Polycom 1500 Getting Started Manual

RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Getting Started Guide
● YES - Cells for dropped endpoints will not be reassigned, but will be reserved until the endpoint
reconnects.
Forced Layout Guidelines
● When a new forced layout is sent to the MCU, the MCU no longer preserves the cells for
disconnected participants. The layout is redrawn using the currently connected participants only.
● If the dropped endpoint was forced to use a particular cell, and that cell is switched from forced layout
to automatically assigned, the MCU no longer preserves the cell. Any other endpoint can be assigned
that particular cell.
● This feature works the same way in Telepresence conferences, even where the layouts are controlled
by MLA.

Enabling and Disabling Video Clarity™ (AVC-based Conferences)
When enabled (default), Video Clarity applies video enhancing algorithms to incoming video streams of
resolutions up to and including SD. Clearer images with sharper edges and higher contrast are sent back
to all endpoints at the highest possible resolution supported by each endpoint. Video Clarity™ can disabled
during an ongoing conference.
To disable or enable Video Clarity:
1 In the Conference List pane, double-click the name of the conference or right-click the conference
name and then click Conference Properties.
2 Click the Video Quality tab.
3 Clear the Video Clarity check box to disable it or select it to enable it as required.
4 Click OK.

Muting all Participants Except the Lecturer (AVC-Based CP Conferences)

The Mute Participants Except Lecturer option can be enabled or disabled during the ongoing conference (in
addition to its setting in the conference Profile). When enabled, the audio of all participants in the conference
except for the lecturer can be automatically muted upon connection to the conference. This prevents other
conference participants from accidentally interrupting the lecture, or from a noisy participant affecting the
audio quality of the entire conference. Muted participants cannot unmute themselves unless they are
unmuted from the Collaboration Server Web Client/RMX Manager.
Muting Participants Guidelines
● Both Administrators and Operators (users) are allowed to set the Mute Participants Except Lecturer
option. It can be enabled at any time after the start of the conference to allow the conference
participants to converse before the lecturer joins the conference or before they are muted.
● When the Mute Participants Except Lecturer option is enabled:
 The mute indicator on the participant endpoints are not visible because the mute participants was
initiated by the MCU. Therefore, it is recommended to inform the participants that their audio is
muted by using the Message Overlay function.
