1. DESCRIPTION
The V6333/DDigitalAudioMultiplexerisafull broadcast specification embedderofaudiodataintoHD
(High Definition)and SD(StandardDefinition)SDI datastreams. Twoversionsofthe V6333 areavailable,
one with4AES inputs(V6333Q/D), and anotherwith8AES inputs(V6333E/D). Although the V6333
processesHigh Definition (HD)video signals, it isfullycompatiblewithall otherproductsinthe range in
termsofformfactor, powersupplyrequirementsand controlinterface. The V6333 isa3U high cardthat can
be fitted intoaV1606 rack oraV6011 '1-Box', fromwhichit obtainsitspowerand control.
Thereisalsoan audiode-multiplexermodule, the V6334, whichisfullycompatiblewiththe V6333.
Apassiverearmoduleisrequired forall signalinterconnections. Thereare3typesofrearmodule; a4
unbalanced input (Singlemodulewidth), an 8unbalanced input (Doublemodulewidth), and one offering 8
balanced inputs(Singlemodulewidth).
The unit automaticallydetectsthe standardand format ofthe SDorHD input video and operates
accordingly.
The unit embedsaudioontoSDI video datastreamaccording toSMPTE272M(SD)and SMPTE299M
(HD). All ofthe availableaudiogroupsmaybe embedded. Unlikemultiplexersfromsomeother
manufacturersthe audiodoesnot need tobe synchronouswiththe video intowhichit istobe embedded.
Thismakesthe useofembedded audiowithinastudioarea muchsimplertoimplement. Howeverit must
be noted that someothermanufacturersde-multiplexerswill not accept embedded audioifit is
asynchronoustothe SDI clock.
Anotherfacilitytoassist the installation inarealenvironment isthe abilitytoresamplean asynchronous
AES input toan externalreference, generating synchronousmultiplexed audio. The externalreference
maybe anotherAES signal, orthe SDI video itself.
ThereareuptotwoSDI outputs, and one re-clocked versionsofthe SDI input. All ancillary datamaybe
optionallystripped off the SDI input signalpriortoembedding. The EDH isoptionallyregenerated on the
cardforSD.
The unit isfullycontrollableoverthe DART remotecontrolsystem.

Manyinstallationshavedifficultywithembedded audio, whichcan often be traced tothe frequency and
phaserelationshipbetween the video and AES audio. UnlikemanySDI multiplexersthe V6333 doesnot
requirethe signalstobe synchronous. Infact it isquitepossibleforthe SDI video and the twomultiplexed
audiodatastreamstohaveno defined relationship.
Toassist inoperationalinstallation the V6333 can be used toresamplethe audioat 48kHzsynchronised to
variousreferencesignals. Thismayhelpifthe audioistobe de-multiplexed at alaterstage byanother
manufacturer’sde-multiplexer. The referencesourcemaybe eitheran AES signalorthe video input.

3.7.5 Output EDH
EDH isamethod ofembedding datawithinthe ancillary dataspacewhichcarriesameasurement ofthe
video and otherdata. By regenerating the equivalent measurement at the receiving end it ispossibleto
check that the datahasbeen received correctly.
HD signalsalwayshavethe EDH dataembedded, but forSDsignalsit isoptional. Onthe V6333 Audio
multiplexer, the EDH on the output can be disabled on the ENG’ING : O/P EDH menu. Caremust be taken
ifthe newEDH generation isdisabled and the oldEDH isbeing passed through becauseit will probablynot
correctlyrepresent the data. Inthiscasethe Ancillary Datareallyought tobe blanked. (Onearlyunitsthe
ancillary dataisalwaysblanked.)

displayon the localfront panelwill not be visiblesoit will go tosleep afteracertaintime. Thistimeout
delaycan be changed on the ENG’ING : Sleep menu tobe anything between 0and 30 minutes; 0minutes
meansthat it will stayon indefinitely. The sleep timeout alwayscountsfromthe last front panelbutton
push. The default timeis5minutes.
The panelcan alsobe forced intoitssleep mode bymoving up alevelfromthe Top Levelmenu which
