6 © VideoCentric Limited 2002 RADVision MCU-323 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 joinmultipoint conferences

43 © VideoCentric Limited 2002 RADVision MCU-323 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.
