The term multiplexer was given to an electronic device that time-multi-
plexes video pictures from numerous cameras onto one VCR. This means
that one field or frame from one camera was switched to the VCR, then im-
mediately following that picture was another field or frame from another cam-
era and so on from each camera, then it started over again. This technique
maintains full resolution as does normal video switchers but reduces the time
betweenrecorded images so the2-3 second dead timebetween normal cam-
era switching was reduce to 17ms (milliseconds) times the number of cam-
eras. The multiplexer electronically marks each picture with a camera num-
ber so it can be identified upon playback.
When the recorded tape is played back through the multiplex the multi-
plexer electronically identifies the desired picture to be viewed. When the
picture is identified the multiplexer updates the viewable image on the moni-
tor so you only see the requested image or images if in the quad mode.
There exits three types of multiplexers in Black & White or Color; Sim-
plex, Duplex or Full Duplex. The Simplex models are for unattended opera-
tion since they can only view switched images when the multiplexer is in the
recording mode. Duplex models allow simultaneously recording on the VCR,
while the operator can view the total number of cameras viewed at once on
the multi-screen display. Full Duplex allows the playback of a second VCR
while viewing the multi-screen display while the first VCR remains recording.
The AVE QM line of multiplexers are Black & White Simplex. They do
however have features above the standard Simplex design. The high resolu-
tion give the QM line the most advanced performance & features of any Black
& White simplex multiplexeres. The name QM stands for Quad or Multi-
plexer since the QM series has the ability to be a real time 60 Hz quad or
sequencing Duoquad (QM8) or a high performance simplex multiplexer. With
2 monitor outputs the user can be viewing the call monitor with live images
while watching the playback on an additional monitor.
For additional information on multiplexers visit the AVE website at
www.americanvideoequipment.com and click “Education”. A more detailed
white paper on multiplexer technology is available here.

8. BASIC OPERATION
Inthis section wewilldiscuss the basicoperationof the multiplexerwithoutdoing any
programming.We will assumetheprogramming is atthefactory default settings. There
aretwo basic modes of operation in the QM; namely the Recordmodeandthe Play back
Mode.
Power Up the QM
Powerup the QM after making the connectionsasshown in the Figure 3. The LEDs
onthe RECORD and FULL buttons will be turnedonwhich is the power up operational
mode. You will see the multiplex image on theVCR monitor indicating that the QM is
sendingthe Multiplexrecordsignal to theVCR. The Callmonitorwill also havethe multi-
plexedsignalin case youare only usingonemonitor.Toview the callmonitorsequencing
throughtthe live views ofall cameras press “MON” andthe “SEQ”. Any blinking LEDon
theCAM buttons indicate that cameras’ input is not present and avideo lossisdetected.
6.1 Record Mode
Thereare 5 possiblewaysof recording intheQM; Multiplex, Quad,Zoom,Full
Screen,and Full ScreenSequencerecording. The VCR monitoroutputwill always show
theactual video signal going totheinput of the VCR. Whileyouare recording in any ofthe
abovemodes you can alsoview the full screen outputof any specific cameraorall the
camerassequentially on the call monitor. To do thatmakesureamonitoris connected to
theMON output of the QM as showninfigure 3. See the MON mode to setthisoption.
Multiplex Recording /Viewing
Bydefault the QM willpower up in the multiplexedrecording mode. The LED onthe
RECORDand FULL buttonsilluminatedonly indicates that theQMis sending multiplexed
images toVCR. You can see the multiplexed image on theVCR monitor also. You can
alsoactivate this modebypressing the “RECORD”buttonany time. If youwantto see any
specificcamera on yourcall monitor, presstheMON buttonthen press the “CAM #”
(where# isthenumber ofcamera you wantto view). Ifyou want to automaticallysequence
throughall the cameras,pressthe SEQ button.TheLEDs on theMON,SEQ, and
RECORDbutton will beon,while the LEDsonthe CAM buttonswillbe ON sequentially
and will remain ON for the amount of time set in SEQUENCE DWELL . See the program-
mingsection to set the sequencetiming. If youconnect a separate monitor onthe“VCR”
outputthen youcan viewthe multiplexed image onthatmonitor.If youdesireto viewthe
multiplexedrecordingimageon the call monitor,pressthe RECORD button.
Warning:When the MONLEDis off youcanchange the recording output signaltothe
VCR.The normal mode of multiplexedrecordingis when the FULL LEDison. If this is off
then either one camera or a sequence of cameras is being recorded as in a normal video
switcher.
