Calls between the TelePresence Server and the following endpoints can include a content channel up to
1080p30:
n Cisco TelePresence System 500-32 (with TX 6.0 software)
n Cisco TelePresence TX1300 Series, TX9000 Series, TX9200 Series (with TX 6.0 software)
1080p30 content in a TelePresence Server conference with these endpoints is possible provided that the
calls have adequate media resources and that the content source is 1080p30.
The upper limits of the TelePresence Server's content capabilities are described in the following table.
Operation mode Frame resolution Frame rate
Remotely managed 1920 x 1080 (Full HD) 30 fps
Remotely managed 1280 x 720 (HD) 60 fps
Remotely managed 1920 x 1200 (WUXGA) 27 fps
Locally managed 1280 x 720 5 fps (with TelePresence Serverin HDmode)

Cisco ClearPath support
The TelePresence Server now supports ClearPath to improve media resilience within lossy networks.This
feature is always enabled for all TelePresence Server platforms and does not require any configuration.
The TelePresence Server implementation of ClearPath includes FEC(Forward Error Correction) and two
other techniques which are only used inside the video streams, namely LTRF(Long Term Reference
Frames) and incoming GDR(Gradual Decoder Refreshes).
ClearPath will be negotiated with any endpoints that support ClearPath, and the TelePresence Server's web
interface and API will report statistics on the media resilience techniques used in those calls.
The following endpoints currently support ClearPath in their most recent software releases:
n Cisco Jabber Video for TelePresence
n Cisco Jabber
n Cisco TelePresence System TSeries
n Cisco TelePresence System Quick Set Series (C20, SX20)
n Cisco TelePresence MXSeries (MX200, MX300)
n Cisco TelePresence System EXSeries (EX60, EX90)
n Cisco TelePresence Profile Series (Profile 42", 52", 52" Dual, 65", and 65" Dual)
n Cisco TelePresence Integrator CSeries (Codecs C40, C60, and C90)
FEC (Forward Error Correction)
The TelePresence Server applies FEC to enable media packet recovery on outgoing video, audio, and
content streams. It can also process incoming streams containing FECpackets and will try to recover media
packets lost from these streams.
