8. A system for providing bidirectional video teleconferences on a mobile platform, the system comprising:
a first video teleconference terminal disposed on a mobile platform;
a first local area network arranged to provide network data services on the mobile platform and arranged to communicate with
the first video teleconference terminal;
a second video teleconference terminal disposed at a terrestrial station;
a second local area network arranged to provide network data services and arranged to communicate with the second video teleconference
terminal, the first and second local area networks being in asymmetrical bidirectional packet data radio frequency communications
via a forward satellite link from the terrestrial station having a forward link rate that is substantially greater than a
videoteleconference call rate and a return satellite link from the mobile platform having a return link rate that is adjustable
to support the videoteleconference call rate, wherein packets of video teleconference data are prioritized over packets of
data for services other than video teleconferencing;
a first quality of service device coupled between the first video teleconference terminal and the first local area network
on the mobile platform and arranged to prioritize first packets of video teleconference data that are transmitted from the
mobile platform over second packets of data that are transmitted from the mobile platform for services other than video teleconferencing;
a second quality of service device coupled between the second video teleconference terminal and the second local area network
and arranged to prioritize third packets of video teleconference data that are transmitted to the mobile platform over fourth
packets of data that are transmitted to the mobile platform for services other than video teleconferencing;
a plurality of headsets, each headset having a microphone and at least one headphone; and
an audio interface connectable to the first video teleconference terminal and the plurality of headsets, the audio interface
unit being arranged to supply to all of the headphones an audio signal that includes first audio signal components from all
of the microphones and that further includes a second audio signal component from the second video teleconference terminal.
