8 Microphones And Stereo Video Conferencing

13 - 38
This example creates a stereo video conferencing system with eight table
microphones, stereo program audio, a VSX8000 stereo video codec, and a
stereo audio amplifier. This application is similar to the 8 microphone mono
example shown previously with the addition of the stereo video codec that
enables both a positional "receive" signal from the remote site and enables a
positional "transmit" signal with the local microphones that can be panned to
the two output channels to encode the position of the local talker to the remote
participants.
The block diagram of this system is shown in the following figure. The channel
names are labeled with the virtual channel names that are created by default
by the SoundStructure Studio software.

The steps to design this configuration are similar to the mono case with the
exception of selecting stereo program audio, a stereo VSX8000, and a stereo
amplifier.
