Introducing the
Concorde•4500
This chapter presents an overview of the major components of a
PictureTel Concorde¥4500 videoconferencing system.
The Concorde¥4500 is a high-performance videoconferencing
system. What makes this a quality performing system is the way it
digitizes and compresses analog video and audio input. This
process signiÞcantly lowers the data rates for the transmission of
video and sound.
The sending system converts the analog video and audio signals to
digital form, compresses the digital data and places it onto the
telephone network. The receiving system decompresses the signal
and displays an image along with sound.
The system can receive video from:
Any one of three pan-tilt-zoom (PTZ) cameras, such as the
PowerCam™ 100
A VCR
A document camera
A Concorde¥4500 system can receive audio from:
A PowerMic™
A wired keypad (which is not standard with the
Concorde¥4500) and up to two additional microphones
attached to it
External tabletop, or lapel microphones
A VCR
