Polycom realpresence 1800 - Support for Hd1080 P Resolution

Appendix H - Deployment Into Microsoft Environments
Polycom®, Inc. 998
Support for HD1080p Resolution
The Collaboration Server Hosted deployment supports HD1080p30 video resolution symmetrically for direct
calls.
The MS AVMCU Cascade deployment supports HD1080p30 video resolution only if
Video Optimized mode
is selected and according to the settings of the LYNC_AVMCU_1080p30_ENCODE _RESOLUTION
System Flag:
NO (Default) Video streams sent to and received from the MS AVMCU are HD720p30, SD, and CIF.
YES Video streams sent to the MS AVMCU are HD1080p30, SD, CIF. Video streams received from
the MS AVMCU are 720p30, SD, and CIF.
Limit Maximum Resolution for MS SVC Using a System flag
The MAX_MS_SVC_RESOLUTION System Flag can be used to minimizing the resource usage by
overriding the default resolution selection and limiting it to a lower resolution.
Range: AUTO, CIF, VGA, HD720, HD1080
Default: AUTO
The MAX_MS_SVC_RESOLUTION System Flag operates independently from the
MAX_RTV_RESOLUTION System Flag allowing differing maximum resolutions to be selected for the MS
SVC and RTV protocols.
If you want to modify System Flag values, the flags must be added to the System Configuration file. For
more information see:
Modifying System Flags and Controlling Resource Allocations for Lync Clients Using
RTV Video Protocol.
FEC (Forward Error Correction)
FEC is supported for RTV and MS SVC video protocols.
● FEC will be automatically turned on by the VSR (Video Source Request) message.
Redundant Audio Data (RED) is supported for the following Audio CODECS:
● G.722
● G.711A
● G.711U
The Collaboration Server transmits RED when packet loss is reported and stops sending RAD when packet
loss is stopped.
For more information see Lost Packet Recovery.
IPv6 Support
In addition to IPv4, IPv6 is supported in Lync 2013 environments.
Following IP modes are supported for all network connections—ICE, Media, Management, Signaling, etc.:
● IPv4 only
● IPv6 only
● IPv4 & IPv6
As in previous versions, IPv4 Candidates are advertised first in the SDP.
