Content Media Protocols - Polycom realpresence 1800 Administrator's Manual

● 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 only.
H.263 is the only media protocol supported by the MCU for content sharing in ISDN endpoints.
● H.264 - Base and high profiles support is according to the table below:
H.264 AVC (non-TIP) conferences
Content Profile
Base profile
High profile
For single MCU conferences, the MCU determines the media protocol and high/base profile by
applying the Highest Common principle (see
high/base profile requires user configuration (see

● TIP content - The supported TIP content rate is XGA, 5 fps, 512 Kbps, base profile (see
- Polycom Open Collaboration Network
Should the minimal TIP content allocation be less than 512 Kbps, content channel will not be opened.
