Multipoint Videoconferencing Through an ---
Embedded MCU
An embedded 4-port Multipoint Control Unit (MCU)
provides robust but easy-to-use multipoint
conferencing capabilities. Users can initiate and
control the Chair of multipoint conferences,
participants may receive the floor temporarily, or an
administrator can set up a dial-out conference,
instantly connecting all parties. The HD3000
implements audio and video transcoding which
enables all participants to receive the optimum
conference quality supported by their systems.
Additionally, the HD3000 employs speed matching,
allowing all participants to connect at different
speeds, as supported by their systems.
System and Call Security
Administrators may restrict access to the system's
configuration, prevent unauthorized outgoing calls, or
lock the system completely.
The HD3000 supports the H.235 protocol, which
provides secure signaling, video and multimedia
communications in an H.323 conferencing
environment.

Precedence to prioritize the video, audio and control
bits, and DiffServ to transfer packets according to the
