This diagram shows a VSX41 used for video source selection in a "corporate video conferencing" application. A similar system could be
used for "distance learning" applications. An ADVANTAGE
®
autoONE automatic (voice-activated) mixer accepts the microphone signals.
When a microphone becomes active, a corresponding Logic Output goes on. The Logic Outputs of the autoONE are connected
(individually or in specific groups) to the Logic Inputs of the VSX41, for "video-follow-audio" switching. Therefore, the VSX41 will
automatically select the appropriate camera when some one speaks. When the "presentation" mic becomes active, the VSX41 switches to
the "presentation" camera. The "presentation" camera has priority over all other cameras. (The audio & video "presentation" signals could
instead be from a VCR or multi-media device.) The "chairman" camera has priority over the "member" & "room" cameras, and the
"member" camera has priority over the "room" camera. The "room" camera can be made to come on whenever no one is speaking, by
wiring the VSX41 Logic Input 4 directly to ground. Manual or automatic audio override can also be assigned to channel 1 of the autoONE
mixer. A VOICECRAFTER provides echo canceling and proper interface of audio signals to the video-conferencing codec.
