Forcing Other Content Capabilities
•
The
H239_FORCE_CAPABILITIES
System Flag
in
system.cfg
gives additional control
over Content sharing:
—
When the flag is set to
NO (default)
, the RMX only verifies that the endpoint
supports the content protocols:
H.263
or
H.264
.
—
When set to
YES
, the RMX checks frame rate, bit rate, resolution, annexes and all
other parameters of the Content mode as declared by an endpoint during the
capabilities negotiation phase. If the endpoint does not support the Content
capabilities of the MCU, the participant will not be able to send or receive content
over a dedicated content channel.
Content Sharing via the Polycom CCS Plug-in for Microsoft Lync Clients
From version 8.1, Polycom CCS (Content Collaboration Solution) Plug-in for Lync clients
allows Lync clients to receive and send
Content
on a separate channel, without having to use
the video channel.
Content
is transmitted using SIP BFCP.
For more information, see Appendix 4, “
Sharing Content Using Multiple Content Resolutions
Mode”
on page
4-18
.
Video Preview (AVC Only Participants)
Collaboration Server users can preview the video sent from the participant to the conference
(MCU) and the video sent from the conference to the participant. It enables the RMX users
to monitor the quality of the video sent and received by the participant and identify possible
quality degradation.
The video preview is displayed in a separate window independent to the
RMX Web Client
.
All Web Client functionality is enabled and conference and participant monitoring as well
as all other user actions can be performed while the video preview window is open and
active. Live video is shown in the preview window as long as the window is open. The
preview window closes automatically when the conference ends or when participant
disconnects from the conference. It can also be closed manually by the RMX user.
Video Preview Guidelines
•
Video preview is available for
AVC
participants. It is not available for
SVC
participants.
•
Video preview window size and resolution are adjusted to the resolution of the PC that
displays the preview.
Video Preview is
not supported when the Collaboration Server is in
Ultra Secure Mode
. For more
