Whendesigningasystemthereareanumberofconsiderationsthatneedtobe
addressedforpropersystemfunctionality.Inthissectionwewilllookatallthe
typicalpiecesofasystemandwhatisrequiredforthesystemtofunctionproperly.
Hardwareconsiderations
Whenchoosinghardwareforcontrol‐basedsystemstherearenumberofquestions
thatneedtobeaddressed.Whattypeofprotocolisusedtocommunicatewiththe
hardware?Whatdevicewillhandleaudioandvideoswitching?Howwillvolume
controlbehandled?Thesequestionswillallneedtobeconsideredwhenlookingat
thehardwareusedinthesystem.Let’slookatsomeoftheconsiderationsforeach
typeofhardware.
Display
Theprimarythingtolookatwhenselectingthedisplayishowwillitbecontrolled.
ThetypicaldisplayhaseitherIRorserialcontrol.Thereareseveraladvantagesto
havingserialcontrol.Devicesusingserialcontrolhavetheadvantageofbeingable
toswitchtodistinctinputs.Thismakessourceselectionmucheasier.Ifyouneedto
pagethroughseveralmenustoswitchinputs,thedisplayisnotidealforacontrol
system.IfyouchooseadisplaywithIRcontrolmakesureithastheabilitytoselect
distinctoutputsources.
