Term

 

 

 

Codec

Coder-decoder. A device that converts voice and video

 

into digital code, and vice versa. Refers to the endpoint

 

video camera and video board that are used for

 

videoconferencing.

 

 

Conference

Connection between two or more endpoints exchanging

 

video and audio information. If only two endpoints are

 

involved, a conference is called point-to-pointand no

 

MCU is required. If more than two endpoints are involved,

 

it is called a multipoint conference, and an MCU

 

(Multipoint Control Unit) is required as the management

 

system. For more information, see MCU.

 

 

DTMF

Dual Tone Multi Frequency. A system of coded signals

 

used by touch-tone telephones in which a specific sound,

 

frequency or tone is assigned to each key so that the

 

signal can be easily recognized by a computer. The codes

 

enable data input and control of voice-processing

 

systems. DTMF signals can pass through the entire

 

connection to the destination device and therefore are

 

used for remote control after the connection with the MCU

 

is established.

 

 

Endpoint

A hardware device, or set of devices, that can call, and be

 

called by an MCU or another endpoint. For example, an

 

endpoint can be a phone, a camera and microphone

 

connected to a PC or an integrated Room System

 

(conferencing system).

 

 

FECC

Far End Camera Control. In certain video cameras, the

 

accompanying software that enables a participant to

 

control a remote camera. Used in Continuous Presence

 

video conferences in conjunction with the LSD option. For

 

more information, see LSD.

 

 

Frame

A group of bits that make up an elementary block of video

 

data for transmission by certain protocols.

 

 

Frame Rate

The number of video frames displayed on-screen during

 

one second, measured in fps (frames per second).

 

 

G.711

ITU-T audio algorithm, 64Kbps, 3.4 kHz.
