What is a Gatekeeper?
A gatekeeper as defined by the
ITU
-T H.323 standards
is an optional device that provides access and
bandwidth usage controls for H.323 devices on an
IP
network.
May also provide address lookup and translation,
conference accounting, and site/conference status
information.
It is the key element in the network that allows
endpoints to find other endpoints, gateways, and
to
join
multipoint
conferences

H.323 Multipoint
MULTIPOINT CONTROLLER (MC) The MC is defined as a
software device which provides control functions
to support conferences between three or more
end-points. MULTIPOINT PROCESSOR (MP) The MP is
defined as a physical device which can process
audio, video or data streams to support
conferences between three or more endpoints

Unit Operation - Conference Modes
VOICE SWITCH
All audio from all participants is mixed within
the MCU and distributed. The loudest audio stream
is selected and video from this participant is
broadcast to all other participants.
FIXED BROADCAST
Video from a selected participant is broadcast to
all other participants regardless of audio (audio
continues to be mixed and distributed). This
feature is available only through the Web
management interface.
CONTINUOUS PRESENCE
Video from the four loudest sites is sent
simultaneously to every terminal in the
conference (in QCIF format). Each terminal
combines the four signals into a single,
quadranted display. Audio continues to be mixed
from ALL sites and distributed back to ALL sites.
