P
P-frame
An easily compressible video frame type. A video frame is compressed using different algorithms that
allow varied amounts of data compression. These different algorithms for video frames are called
picture types or frame types. The three major picture types used in the different video algorithms are I,
P, and B.
PiP
Presentation-in-picture. Data or graphics content sharing through an external monitor known as
presentation-in-picture (PIP) format for space-constrained offices. You can toggle the position of the
PiP between center, left, or right locations on the screen. PiP is not present on the CTS 3000 or
CTS 3200 series.
PoE
Power over Ethernet.
Presentation Codec
The presentation codec provides 30 frames per second to support full-motion video presentations
between Cisco TelePresence endpoints.
Primary Codec
The primary codec is the primary unit; it communicates with secondary units, sends and receives
packets on the uplink network. It contains an onboard Gigabit Ethernet switch. For example, in a
CTS 3000 or CTS 3200 system, the primary codec controls two secondary codecs as well as many
system components and the graphical user interfaces (GUI). In a Cisco TelePresence 1000, it controls
all system functions.
PCB
Printed circuit board.
R
RFC
Request for Comments. Document series used as the primary means for communicating information
about the Internet. Some RFCs are designated by the IAB as Internet standards.
S
Scheduling API
Cisco TelePresence Scheduling API provides programmatic access to your organization's
CTS-Manager using a simple, powerful, and secure application-programming interface for customers
who are not using Microsoft Exchange or IBM Domino Notes. For developers this API allows
groupware applications to utilize Cisco TelePresence Manager for scheduling Cisco TelePresence calls
with resource reservations and
One-Button-to-Push
.
screen resolution
The fineness of detail that can be presented in the image on the plasma display.
SD
Standard definition display.
secondary codec
Codecs that assist the primary codec in the large Cisco TelePresence 3000/3200 systems. Secondary
codecs process audio and video signals and send them to the primary codec, which multiplexes the
signals into separate, single RTP streams.
single system
A Cisco TelePresence system featuring a single main display.
