Sharing Content During Conferences
Polycom®, Inc. 103
Endpoints supporting People+Content (for example, FX endpoints) may require a different signaling
protocol. For these endpoints, manually add the System Flag CS_ENABLE_EPC, and set its value
to YES (default value is NO).
Content Media Protocols
The RealPresence Collaboration Server transmits content using the following content media protocols:
H.263 (Annex T) - Base profile.
H.264 - Base profile.
For single MCU conferences, the MCU determines the media protocol by applying the Highest
Common principle (see Highest Common).
.
TIP - Cisco’s proprietary protocol for TelePresence endpoints. The supported TIP content rate is
XGA, 5 fps, 512 Kbps, base profile (see Appendix I - Polycom Open Collaboration Network (POCN)).

LPR has no effect on content rate, though due to the increased number of frames, video rate is
decreased.
