The GefenPRO 3GSDI Audio De-Embedder
TheGefenPRO3GSDIAudioDe-Embedderextractsaudiofrom3GSDI,Single-Link
HDSDI,EDSDI,andSDIvideosignals.UptofourAES/EBUdigitalaudiostreamscanbe
de-embeddedandroutedtoanyofthefouraudiooutputs.Selectionandroutingofeach
audiogrouporpaircanbeconguredviaRS-232.
How It Works
ConnectanSDIsourcetotheSDIInconnector.ConnecttheSDILoopOutconnectorto
anSDIaudio/videodevicetomonitortheoriginalunmodiedsignal.ConnecttheOutput

channels.Beforegettingstarted,seepage10onconguringRS-232.
1. TherststepistoroutewhichSDI audio input groupsaretoberoutedtothesource
groups.Usethe#sdi_in_grp_swcommandtoassignthespeciedSDI audio
grouptothedesiredsource group.

Inthisexample,wewillrouteSDI audio input group1(g1)tosource groupS2and
SDI audio input group3(g3)tosource groupS1:

#sdi_in_grp_sw g1 s2
Error! G1 has been already assigned to S1


Here,wetriedtorouteGroup1toS2.However,bydefault,Group1isalreadyrouted
toS1.Wemustrst“un-route”Group1byroutinganunusedSDIaudioinputgroupto

Forthisexample,wewillalsoadda50msaudiodelaytoO1.2:

Un-routed Source and AES Channels
Note,thatinourexample,thatwedidnotroutesourcechannelsS1.3andS2.2.
Accordingtotheblockdiagramonpage8,eachsourcechannelisroutedtoan
associatedoutputchannel(S1.1>O1.1,S1.2>O1.2,etc).Thisisthedefaultsetting.

AlthoughwedidnotspecifyS1.1toberoutedtoO1.1,thedefaultroutingstatestill
applies(indicatedbythedashed-lines).Thesameholdstrueforthedefaultrouting
stateforS1.4>O1.4,S2.2>O2.2,andS2.4>O2.4.Inaddition,AESaudiochannels
(A.1...A.8)willreceivesourcechannelsS1.1throughS2.4,respectively.

ItisimportanttounderstandthatsinceS1.3wasneverroutedinourexampleand
becauseS1.1wasroutedtoO1.3,thedefaultroutingforS1.3(S1.3>O1.3andS1.3
>A.3)cannottakeplace.


Muting Channels
The3GSDI Audio De-EmbedderallowsanyoutputorAESchannel(orallchannels)
tobemutedbyusingthe#mutecommand(seepage22fordetails).Thiscommand
isusedtomutespecicaudiochannelsbeforebeingsenttotheoutputconnectors.

Forexample,thefollowingcommandwillmuteAESchannelA.4:
