Administrator's Guide,
Video Switching Conferencing Mode (Collaboration Server 1500/2000/4000 only)
In Video Switching (VSW) mode all participants see the same video picture (full screen). Only one CIF video
resource is used for each connection. Video Switching mode is not supported in Collaboration Server 1800.
In VSW conferences:
 All endpoints must connect to the conference at the same line rate. Line rates range from 192Kbps
to 6Mb. The Collaboration Server will always connect participants at the highest possible video
quality that is supported by the conference Line Rate.
 All endpoints must connect to the conference at the same video protocol and resolution. Video
Protocol and Resolution ranges from H.261 CIF to H.264 1080p60.
 Compliant endpoints must connect to conferences at the conference line rate and resolutions.
Endpoints that do not meet the conference requirements connect as Secondary (Audio Only) if
there are resources defined for Voice connection or they will disconnect from the conference if
there are not such resources.

Administrator's Guide,
AVC-based Video Resolutions
The resolution in which participants connect to the conference is determined by system according to their
connection line rate and the endpoint's capabilities.
Resolution Configuration for AVC-based CP Conferences
The minimum threshold line rates at which endpoints are connected to the conference at the various video
resolutions are determined in the Resolution Configuration dialog box. Using the Resolution Configuration
sliders, you can modify the video resolution decision matrix, effectively creating your own decision matrix.

AVC-based Video Switching Resolutions (Collaboration Server (RMX) 1500/2000/4000 only)
In Video Switching (VSW) conferences, participants must connect at the conference line rate, video protocol
and resolution. Endpoints that cannot connect using these settings will be connected using Audio only and
their status will appear as Secondary (no video).
The video quality for the conference is determined by the conference video protocol and resolution and it
should be set based on the endpoint with the lowest capabilities that will be connected to the conference.
● Available resolutions in Video Switching mode are: H.261 CIF, H.263 CIF, H.264 CIF, H.264 SD 30,
H.264 720p 30, H.264 720p 60 and H.264 1080p60.

SVC-based Conferencing (Media Relay)

Media Relay SVC Conferencing is based on the Scalable Video Coding (SVC) video protocol and Polycom's
proprietary Scalable Audio Coding (SAC) protocol. It offers high resolution video conferencing with low
end-to-end latency, improved Error Resiliency and higher system capacities.
